Steep Cost Reductions Confirmed as Ribbon Cut on Giant Dudgeon Offshore Wind Farm

The giant 402MW Dudgeon offshore wind farm off the coast of Norfolk was officially opened yesterday, providing further evidence costs are falling sharply across the industry.

Operator Statoil and its partners Masdar and Statkraft announced the construction costs for the project had fallen more than 15 per cent from £1.5bn to £1.25bn since the original investment decision for the project was made in 2014.

The project and its 67 turbines are now fully operational, providing enough power to the grid for up to 410,000 homes.

Statoil’s CEO Eldar Sætre hailed the project as “an important contribution to realizing the UK’s renewable energy strategy”.

“The UK has already achieved impressive reductions in CO2 emissions with clear policies to phase out coal, and last year achieved the lowest CO2 emissions since before year 1900,” he said. “Statoil is proud to contribute to this both by being a large supplier of natural gas and by our investments in offshore wind.”

He added the project was further evidence of Statoil’s plan to diversity its portfolio of energy projects.

“As part of our strategy to develop from an oil and gas company to a broad energy major, Statoil will grow significantly in profitable renewable energy, with an ambition to invest around NOK 100 billion towards 2030,” he said. “Dudgeon has successfully been developed in cooperation with Masdar and Statkraft, and is a key part of Statoil’s strategy to complement our oil and gas portfolio with profitable renewable energy solutions, as well as adding to Statoil’s strong UK presence.”

The company is now hoping to curb costs further for the Dudgeon wind farm and the neighbouring Sheringham Shoal project.

“Over recent years Statoil has worked hard to reduce costs, improve efficiency and increase profitability in both our oil and gas projects and our renewable projects,” said Statoil’s executive vice president for Technology, projects and drilling, Margareth Øvrum. “Reducing costs by more than 15 per cent, or £250m, at Dudgeon and completing the construction phase without any serious incidents is a great achievement by all three partners.”

The news came as the UK government cranked up pressure on offshore wind developers to deliver further cost reductions.

In a surprise move the Budget confirmed the existing £557m budget for clean power auctions through to 2021 would be extended to 2025 with no further funding assigned.

The government said the rapid recent fall in renewables costs meant no further funding was needed to meet the UK’s clean energy goals over the period. It also hinted some additional contracts could be offered if projects could show that they can be delivered without any increase in levies and helped meet the government’s strategic goals.

However, the government’s official projections predict negligible increases in capacity for all forms of renewables barring offshore wind, which it expects to rise from 5.2GW to 14GW by 2025.

“The renewable energy industry has a little more certainty than it did this morning,” RenewableUK’s chief executive Hugh McNeal said yesterday. “The existing budget of £557m remains intact, and there is a commitment to maintain the Carbon Price Floor at current levels until coal comes off the system. The removal of an annual cap on the Levy Control Framework reduces the risk of a boom and bust cycle. While this is welcome, what is missing is the ambition to take full advantage of the UK’s global-leading renewables industry at such a crucial time for our country.”

James Court of the Renewable Energy Association said the failure to increase the £557m budget could lead to a hiatus in renewables investment.

“The UK government seem to be turning their back on renewables by announcing no new support for projects post 2020 and a freeze on carbon taxes,” he said. “This could see a hiatus in much needed infrastructure development. Considering this is coming only a couple of months after the much vaunted Clean Growth Plan, it’s hugely disappointing.”

Tesla is set to deliver on its promise to complete the world’s largest lithium-ion battery project within 100 days, after the South Australian government today confirmed testing of the high profile installation is about to get underway.

Earlier this year, Tesla chief executive Elon Musk made a public promise to deliver a large scale energy storage project capable of tackling South Australia’s recent grid instability within 100 days, promising that it would be delivered for free if the self-imposed deadline was missed.

The company subsequently won a competitive tender for the 129MWh project and signed a grid connection deal in last September.

South Australia’s State Premier Jay Weatherhill confirmed today that testing of Tesla’s Powerpacks is now set to begin following their installation at a wind farm operated by French developer Neoen.

“While others are just talking, we are delivering our energy plan, making South Australia more self-sufficient, and providing back up power and more affordable energy for South Australians this summer,” he said in a statement.

The hope is the project will be fully online in time for summer demand peaks, minimising the risk of the blackouts that have marred South Australia’s grid in recent years.

Weatherhill said the project would provide an important part of the state’s wider A$550m energy infrastructure upgrade programme, which promises to deliver a wave of new renewables, energy storage, and back-up power plants.

“The world’s largest lithium-ion battery will be an important part of our energy mix and it sends the clearest message that South Australia will be a leader in renewable energy with battery storage,” he said.

India Installs 2.2 Gigawatts Of Solar In Third Quarter

India installed a total of 2.2 gigawatts worth of solar in the third quarter, up 300 megawatts from the previous quarter, and left another 1 gigawatt unconnected due to grid issues caused by government agencies, according to Mercom India.

Mercom India Research published its third-quarter India Solar Market Update report this week, detailing a total of 2,247 MW (megawatts) of new solar capacity constructed and added to the Indian grid during the third quarter. This might sound pretty good, considering that India installed an impressive 4.8 GW (gigawatts) in the first half of 2017 — and it is pretty good, when you take into account India only installed 4.3 GW of solar for the whole of 2016.

However, according to Mercom India Research, approximately 1 GW worth of large-scale solar projects were left completed but unconnected due to grid connection and grid evacuation delays caused by government agencies. Mercom explains that these delays further contributed “to the slower than expected installation figures seen in Q3” — which shows just how much experts are expecting from the Indian solar industry this year.

Throughout the third quarter a total of 265 MW worth of rooftop solar was installed, and 1,982 MW worth of large-scale solar projects, bringing 2017’s cumulative installed solar capacity up to 7.1 GW. Meanwhile, India’s pipeline of utility-scale projects currently sits at around 11.5 GW, with another 5.6 GW worth of tenders pending auction.

“Even though the Indian solar market is on pace for a record-breaking year, the momentum has definitely slowed,” said Raj Prabhu, CEO of Mercom Capital Group. “Just like the preceding quarter, we saw many project commissioning dates get delayed. In addition, there are approximately 1 GW of large-scale solar projects that are complete but unable to get connected to the grid. These factors are likely to lead to a weaker-than-projected Q4.”

Looking forward, Mercom predicts that total solar installations for 2017 will peak in the range of 9.5 GW to 10 GW, before sliding back to 7 GW in 2018.

Mercom also highlighted the fragility of the Indian solar market at the moment, caused by uncertainty over tariffs and tax rates. “After solar tariffs fell below the ₹2.50 (~$0.0385)/kWh level in Q2 2017, tender and auction activity came to a grinding halt as distribution companies (DISCOMs) pushed developers to match those low tariffs no matter what state they were in,” Mercom India Research noted, adding that “the central government has directed states to honour signed PPAs and not to try and renegotiate contracts, they cannot force DISCOMs to buy power at any price.”

There is also ambiguity surrounding what GST tax rates will apply to which component of solar manufacturing, with 5% set for solar modules as the only component with any real clarity, compared to the possibility of GST rates anywhere between 18% and 28% for other components.

“An extremely cost sensitive market like India will find it very tough to handle any aggressive imposition of tariffs,” explained Prabhu. “The developer community could adjust and model their bids accordingly, but we are concerned that state utilities who are already renegotiating PPAs so that they can procure solar power at the lowest possible prices will stop buying more solar if the tariff moves toward the ₹3.50 (~$0.054)/kWh level.”

Australia Could Go 100% Renewable By 2030

New research from the Alternative Technology Association has showed that Australia could transition to a fully renewable energy electricity grid by 2030, which would be cheaper and less risky than building new coal-fired power stations.

“Australia should transition quickly to a 100% renewable electricity grid, as it is cheaper and less risky than the alternative of building new coal-fired power stations,” wrote the Alternative Technology Association’s (ATA) Energy Projects Team, led by Andrew Reddaway, an energy analayst at the ATA, a transition which they believe “can be achieved by 2030.” The report takes into account recent research conducted by the Australian National University (ANU) and considers recent trends and developments in local projects such as the Snowy Hydro 2.0 to forecast likely progress towards a 100% renewable energy electricity grid.

For a fully-renewable operation of Australia’s National Electricity Market, a total of 93.3 GW of renewable energy generation capacity is necessary. If solar and wind installation continues at the 2017 rate this would happen by 2040, but to reach this milestone by 2030 would require an acceleration of 80% from current trends.

On top of accelerating wind and solar development, the ATA forecast envisions pumped hydro storage increasing to cover intermittency issues. The various energy storage projects in mind are shown in the chart below, showing energy storage capacity in MWh and as a percentage of the 490,000 MWh required for a 100% renewable electricity grid.

“Electricity from new-build coal-fired power stations would likely cost between $81 and $182 per megawatt hour,” said lead author Andrew Reddaway. “This becomes a range of $102 to $203 once we allow for hidden health impacts and climate impacts.”

“In a fully renewable electricity grid, electricity would cost about $93 per megawatt hour. This includes the cost of building energy storage and extra transmission to manage intermittency.”

These costs are only likely to continue to widen apart as we increase our understanding of the impacts of coal-fired generation and as renewable energy technology costs continue to decrease.

“Australia should prepare a proper plan for 100% renewable energy, and implement it,” continued Reddaway. “Decisions should not be left to separate companies driven by short-term profits because this might lead to a poor overall system.”

Global Electric Car Sales Up 63% In 3rd Quarter, BNEF Reports

Foto-ilustracija: Pixabay
Photo-illustration: Pixabay

It’s good news, bad news time at Bloomberg New Energy Finance. First, the good news. Global electric car sales (including plug-in hybrids) surged 63% in the third quarter of this year and are up 23% since the second quarter. BNEF is now confident EV sales will top 1,000,000 units this year. The bad news? China accounted for almost all of those increases.

Sales of electric cars totaled 287,000 in July, August, and September, with China responsible for half of them (something you already knew). Sales in other markets are trending up gradually, but nothing like what is happening in China. The increase in EV sales in China can be traced directly to a number of government policies that strongly encourage people to purchase an electric car instead of a conventional car, as well as fast growth of its car market overall. Many policymakers are worried their own incentive programs are too generous, but the Chinese experience makes it clear that if you want people to buy electric, you have to make it worth their while up front.

“The Chinese government is very focused on pushing up EV sales,” says Aleksandra O’Donovan, advanced transport analyst at BNEF and one of the authors of the report. “One reason for that is the local pollution levels in the cities, and a second is for China to build domestic heroes to compete internationally in this market.”

Many countries are sending mixed messages about their electric car policies. On one hand, they are talking about banning conventional cars. On the other, they are complaining incentives are budget busters that disproportionally benefit the wealthy. The main issue is that EVs still cost quite a bit more than the least expensive conventional cars, the ones that many people rely on for daily transportation. Incentives may not make a big difference to wealthy buyers, but they can make all the difference for low-income drivers who need basic transportation to get back and forth to work.

China proves electric car incentives work. One key question is, can governments afford them? Another is, do they have the political will to provide them? The factor that could make incentives unnecessary is lower battery prices. Batteries make up a large part of the price of electric cars. The less they cost, the more affordable those cars will be and the less the need will be for incentives. Until then, incentives matter.

The e-Volution of vehicles continues WOULD YOU TRY OUT AN ELECTRIC VEHICLE?

Photo: Volkswagen

When it comes to vehicles of the future, most people will immediately think of electric cars. The reality, however, is different. In fact, electric cars are already part of our present. Nowadays, the interest in EVs is growing on many markets, Serbia included. Besides environmental protection and more economical charging, there are numerous reasons for purchasing EVs, some of which are presented below in further detail:

  • „ These vehicles provide quiet operation and do not add to the noise pollution.
  • „ There is no tailpipe emission and no air pollution due to smog.
  • „ Flexible and easy charging. You can charge your vehicle at work or at home – all it takes is to pass a cord through and connect it to a socket.
  • „ Fewer repairs resulting from reduced likelihood of a mechanical failure.
  • „ Easier to maintain.
  • „ Improved cost‑efficiency in the long run.

Second generation electric Golf cars, now based on the improved existing seven series, can already be seen on the roads in this country. Improvements have been made to a number of features: battery power is declared to the level of 35.8 kW/h while the aggregate power is increased to 100 kW, which can be easily converted to 136 hp. On the basis of these performances, one can very easily determine the realistic driving mileage, charging time, and of course the price of consumption.

e-Golf can now run for over

200 kilometers in the everyday drive

on a single battery charge

With electric energy, everything is strictly defined, and the power of an electric engine in kW equals the product voltage (220 V) and electricity (A). With a 10A charger, it takes a modest 2.2. kW of power, but also almost 18 hours of charging time, to reach the full capacity of 35.8 kW. A more powerful charger will reduce this time proportionally to its power and amperage; thus with a 40kW charger, your e‑Golf may be “ready to go” within 45 minutes.

Users largely drive by day and recharge their vehicles overnight, at reduced rates. The cost‑efficiency of e‑Golf can be demonstrated through the following example: the 10A charger, which comes as a part of an e‑Golf package, takes roughly 10 hours to charge to full battery potential, using up about 25 kW/h of electric energy. A simple calculation shows such charging will end up costing us a total of 125 dinars or 1 EUR. The additional advantage is that daily charging requires only a regular power socket.

As for the annual average, which is relevant for all users, e‑Golf can now run for over 200 kilometers in the everyday drive on a single battery charge, depending on the driving style, use of air conditioning and other parameters. Quality driving enthusiasts will also be interested to learn that e‑Golf can accelerate to 100 km/h in 9.6 seconds.

It is particularly interesting that e‑Golf lost none of its driving comfort or the signature design. The LED headlights, characterized by low electric energy consumption, enhance its appearance with a new, technological flair. Blue designer elements and aerodynamic optimization provide it with additional standout features.

Numerous advantages notwithstanding, there are real constraints that continue to slow down the popularization of the concept of electrical mobility. One of them is the price, which remains relatively high at the moment of purchase. Given that cost‑efficiency of e‑vehicles is far higher compared to conventional vehicles, the starting price of e‑models should not be directly compared to the equivalent standard models. The price of e‑Golf models starts at €40,000.

Building a network of public charging points in Serbia is a project well underway and particularly contributed to by the company Porsche SCG, the authorized representative of the Volkswagen brand. Always ready to get involved in a project of this type, they have placed a charging point for EV users on Zrenjaninski put 11, the location of Volkswagen authorized dealership and service center, Porsche Beograd Sever.

Indian State Earns Nearly $1 Million Selling Excess Wind Power In 14 Days

Photo-ilustration: Pixabay
Photo-illustration: Pixabay

The record wind energy generation that India witnessed brought in record revenue (and profit!) for the state of Tamil Nadu, the leading producer of wind power in the country.

According to officials, the state power distribution company sold 11.94 gigawatt-hours of wind power over 14 days in August of this year on the open market. Around 500 megawatts of wind power was sold per day in the market for two to four hours over the 14-day period.

This exercise reaped revenue of more than Rs 61 million ($0.95 million). The average per unit cost translates into around Rs 5.16/kWh (7.9¢/kWh). The Tamil Nadu Generation and Distribution Company Limited (TANGEDCO) buys wind power at tariffs of Rs 3.00-4.15/kWh (4.6-6.4¢/kWh). The company thus earned a profit of Rs 1.01-2.16 on each kilowatt-hour of electricity sold. The overall profit for the company is around Rs 12 to 26 million ($183,725-$398,071) during this period.

Given that this is the first time that TANGEDCO has actually managed to generate a profit by selling wind power speaks volumes of the opportunity that the company will have every year during the monsoon season of high-speed winds.

Tamil Nadu, and India, witnessed the highest-ever wind energy generation this year. In July, Tamil Nadu witnessed 5 gigawatts of wind energy generation for the first time ever, while in August it recorded the highest-ever single day generation, exceeding 100 gigawatt-hours.

The state had to reduce generation from thermal power plants by 50% in order to accommodate the excess wind power in the grid. However, around 40% of the wind power generated was lost due to inadequate transmission capacity.

In July we reported that for more than 2 hours on July 11th, Tamil Nadu generated a record 5,079 megawatts of wind power. This forced TANGEDCO to shutdown 1,020 megawatts of thermal power capacity and operate several other power plants at half of their capacity.

While the Ministry of New & Renewable Energy has directed all states to procure all electricity generated from solar and wind energy projects, even if they have to shutdown thermal power plants, this directive has not been implemented fully. One of the major reasons for this is the lack of adequate transmission capacity and the intermittent nature of these power technologies which puts traditional grid infrastructure at risk.

UK Environment Department Using 1,400 Disposable Coffee Cups a Day

Photo-ilustration: Pixabay
Photo-illustration: Pixabay

More than 2.5m disposable cups have been purchased by the UK’s environment department for use in its restaurants and cafes over the past five years – equivalent to nearly 1,400 a day.

The Liberal Democrats’ environment spokesman, Tim Farron, said the revelation, obtained through a freedom of information request, showed Michael Gove “needs to get his own house in order” in light of his public pledges to tackle the growing scourge of plastic pollution.

The Lib Dems revealed that 516,000 disposable cups had been purchased by the Department for Environment, Food and Rural Affairs’ (Defra) catering contractors in the last year alone, under two separate outsourced contracts for use in catering outlets across its sites. The figure was 589,700 in 2016 and 785,100 the previous year.

The catering contractors did not previously provide any reusable cups, but purchased 200 reusable cups on 31 October 2017.

Separate figures uncovered by the Lib Dems have revealed the House of Commons itself is also failing to get to grips with disposable cup waste, using almost 4m disposable cups in the past five years.

They reveal that 657,000 disposable cups have been purchased by the Commons’ catering service in the last year alone – equivalent to 1,000 per MP – but down from 918,700 in 2013. In addition, 500 reusable or so-called “keep cups” were purchased in 2013, but only four of these have been sold in the last three years.

An estimated 3bn paper cups are thrown away in the UK every year, but it was revealed last year that less than one in 400 is recycled, meaning that millions end up in landfill. The plastic lining in cups means they cannot be recycled in normal depots and have to be put in special bins and sent to one of three dedicated recycling mills.

The Liberal Democrats are calling for the introduction of a 5p charge on disposable coffee cups in the budget, following the success of the plastic carrier bag charge which has reduced usage in England by 85 per cent since it was introduced in October 2015.

The chancellor, Philip Hammond, is expected to announce in Wednesday’s budget a “call for evidence” on how taxes or other charges on single-use plastics such as takeaway cartons and packaging could reduce the impact of discarded waste on marine and bird life. Under Defra’s litter strategy launched in April, a working group has been set up drawing together industry and retailers to develop further practical steps to tackle plastic waste.

“It’s astounding that the department which is supposed to be protecting our environment is responsible for such a colossal amount of waste” said Farron. “Millions of plastic cups have been thrown away by the government, some of which will now be polluting our seas, rivers and countryside. Michael Gove needs to get his own house in order. A coffee cup charge should be introduced in the budget to tackle waste and encourage the use of reusable cups, including in the civil service and parliament.”

A spokesperson for Defra said: “We are committed to reducing unnecessary waste within the department and these figures show the number of disposable cups used has fallen by more than half since 2013. We are working with our suppliers to see what more can be done to further cut their use and promote recycling.”

France Won’t Achieve Goal Of Reducing Nuclear Share Of Power Mix To 50% Until 2030–2035, Environment Minister Reveals

France won’t achieve its goals of reducing the share of its power mix held by nuclear energy to 50%, down from 75%, until the 2030–2035 timeframe (rather than by the 2025 target), the country’s environment minister Nicolas Hulot has revealed.

That means that the country’s goal to reduce reliance upon nuclear energy to a notable degree will be running at least 5–10 years late — and possibly even longer than that. The original 2025 goal was dropped because it was “not realistic” and would increase carbon dioxide emissions, according to Hulot.

As a reminder, the 2025 goal was set by the previous administration, not by the current one, so it shouldn’t be too surprising to see it dropped.

“We will probably have to delay until 2030 or 2035, we will see, at the latest 2035, but don’t ask me to be more precise as that would mean everything has already been decided,” stated Hulot while being interviewed on BFM Television.

“He added that in the coming year, the government would hold public consultations and talks with unions and the energy sector to come up with a new deadline and a program for closing nuclear reactors,” Reuters reports.

“On Tuesday, Hulot said that reaching the 50% target by 2025 would mean closing 17 to 25 nuclear reactors. France is the world’s most nuclear-reliant country. State-controlled utility EDF generates about three-quarters of French power with 58 nuclear reactors in 19 nuclear plants.

“EDF argues that it makes no economic sense to close well-functioning nuclear plants and instead wants to extend the lifespan of its nuclear reactors from 40 to 50 years and longer.”

Critics responded to EDF’s stated desire by noting that it would be cheaper to invest in renewables such as solar and wind energy than it would be to safely maintain the country’s current nuclear reactor fleet for such a long time.

200 Megawatts To Be Re-Tendered At India’s Largest Solar Power Park

India’s largest solar power park, in Karnataka, will witness a re-tendering of 200 megawatts of capacity shortly.

The tender was first issued in July 2017 but was withdrawn the following month. The tender was floated to auction 200 megawatts of capacity in blocks of 50 megawatts each. The solar power park at Pavagada was planned by the Solar Energy Corporation of India in partnership with the Karnataka Renewable Energy Development Limited.

Karnataka will procure electricity generated from the solar power park through long-term power purchase agreements of 25 years. The solar power park will have an eventual installed capacity of 2,700 megawatts.

Some of the leading solar power developers are already working on projects allocated to them in earlier auctions. Adani Power and Tata Power Solar each are developing 150 megawatts, Acme Solar and Fortum are working on 100 megawatts each while Arrow Solar and ReNew Power are working on 50 megawatts of capacity each. The total of 600 megawatts of capacity is expected to be operational by December of this year.

The power generated from these solar power projects will be bundled with thermal power generated from coal-fired power plants owned by NTPC Limited. So, while these six developers placed bids of around Rs 4.80/kWh (7.3¢/kWh), the power distribution companies that will purchase the electricity will pay Rs 3.30/kWh (5.51¢/kWh) for the bundled electricity.

The region that hosts this solar power park has been facing drought for several years now. The government is looking to support the local population through economic development. For this, Rs 200 million ($3 million) will be collected from the project developers. The fund will be used to establish schools, health centers, roads and other basic infrastructure in the region.

China Aims To Plug Renewable Energy Losses By 2020

Photo - ilustration: Pixabay

China may be the largest renewable energy generator in the world, but it still has to sort issues related to integration of wind and solar power in the existing transmission grid.

According to the National Energy Administration (NEA), curtailment of hydro, wind, and solar power projects is expected to drop this year, with the government planning to reduce it to zero by 2020. Curtailment of hydro power in Yunnan and Sichuan province is expected to decline to 10% this year.

Wind energy curtailment in Gansu and Xinjiang provinces is expected to decline to 30% while that in Jilin, Heilongjiang, and Inner Mongolia is expected to fall to 20%. Solar power curtailment is expected to fall to 20% in Gansu and Xinjiang provinces and to 10% in Shaanxi and Qinghai provinces this year.

The northwestern provinces are blessed with immense renewable energy potential but are the farthest from big energy consuming centers in southeastern provinces. Due to the intermittent nature of wind and solar power and the lack of adequate transmission infrastructure in the north-western provinces, a huge amount of electricity is wasted.

Bloomberg New Energy Finance also issued a map highlighting the provinces that have the greatest risk of curtailment. Xinjiang, Gansu, Qinghai, Ningxia, and Inner Mongolia were noted to have the greatest curtailment risk. Last year, 56.2 terawatt-hours of electricity was curtailed.

China has taken measures to reduce this curtailment. Last year, the National Development and Reform Commission mandated grid companies to purchase electricity from wind and solar power projects so as to let them function a set minimum hours in a year.

The NRDC has ordered that enough power from wind energy projects be procured so as to allow them to function for at least 1,800 hours in a year. The figure for solar power projects is at least 1,300 hours. The mandatory procurement will be applicable across 11 provinces including Xianjing and Gansu.

California To Meet 2030 Renewable Energy Targets By 2020

A new report from the California Public Utilities Commission has concluded that the state’s major utilities have already met or will all soon exceed the state’s 2020 renewable energy target of 33%, and will likely meet the 2030 target of 50% by 2020.

California is well-known as a world leader in clean energy technology deployment, but the California Public Utilities Commission’s (CPUC) annual Renewables Portfolio Standard (RPS) report published earlier this month shows that the state’s utilities are well ahead of the RPS targets — specifically, to source 33% of retail sales per year from eligible renewable energy sources by 2020 and 50% by 2030.

As can be seen below, California’s investor-owned utilities have already surpassed their interim targets and, according to the CPUC, “have sufficient resources under development to exceed the 33% by 2020 RPS requirement.”

On top of the fast pace of renewable energy deployment, California’s RPS program has similarly helped reduce the cost of renewable electricity, with the price of utility solar contracts between 2008 and 2016 falling by 77%, while the price of wind contracts between 2007 and 2015 fell by 47%.

Further, the CPUC predicts that, on aggregate, California’s utilities will meet its 2030 RPS requirements of 50% by 2020.

“There is no greater time than now to fight climate change, and California is leading the way,” said CPUC Commissioner Clifford Rechtschaffen, who is assigned to oversee the CPUC’s RPS proceeding. “Our utilities are exceeding the goals we put in place for them. Costs have continued to decline, and reliability has not been compromised in any way. California’s successful program offers lessons for other states interested in advancing clean energy policies.”

The smaller Community Choice Aggregators (CA) and the small and multi-jurisdictional utilities (SMJU) all report compliance with current RPS requirements and are on track to meet their 2020 targets, but more work will need to be done to meet post-2020 targets.

India’s Wind Energy Generation Up 35% In Q3 2017

Photo-illustration: Pixabay
Photo-illustration: Pixabay

Good monsoon winds and a sharp jump in installed capacity helped India generate record wind energy in the July-September 2017 quarter.

According to data released by the Indian government, wind energy generation in the country jumped 35% in Q2 2017 compared to the preceding quarter. The generation was up 25% compared to Q3 2016. This quarter-on-quarter increase was likely the result of high wind speeds thanks to a good monsoon season this year. The year-on-year jump was the result of a 14% increase in installed capacity between October 2016 and September 2017.

Total wind energy generation in India increased from 15.8 gigawatt-hours in Q2 2017 to 21.3 gigawatt-hours in Q3 2017. The share of wind energy in the total power generation or imported in India on quarterly basis touched a high of 6.4% in Q3 2017, up from previous high of 5.4% in Q3 2016.

Within renewable energy generation, the share of wind energy increased to its second-highest level. The share of wind energy within renewable energy generated in India during Q3 2017 touched 67.9%, compared to 62.2% in Q2 2017 and 61.8% in Q3 2016.

In July of 2017, the share of wind energy in India’s total power generation and import touched an all-time high of 8.9%, surpassing the previous high of 6.7% in July 2016. Wind energy’s share within the renewable energy generated in that month was also at an all-time high of 76.2%. The absolute wind energy generation in July 2017 also touched an all-time high of 9.8 gigawatt-hours. India can be expected to see more than 10 gigawatt-hours of wind energy generation in June or July next year.

However, the rise in generation next year may not be as high as it is this year. Wind energy capacity addition has taken a massive hit this year. Project developers are no longer being allowed to add projects under the feed-in tariff scheme and are required to set up projects through competitive auctions. This will significantly impact the capacity addition.

The first wind turbine at the Mount Emerald Wind Farm near Walkamin has been sucessfully erected, marking a significant milestone for the biggest wind farm in Queensland.

The turbine consists of three 16 tonne blades, each 57m long, that were positioned in place atop the 90-metre tower after the project’s first towers were raised last week.

Each tower is made up of four separate sections and is anchored to an 800-tonne concrete and steel foundation using 168, 36mm bolts.

The turbine’s 120-tonne nacelle (the box that houses all of the generating components in a wind turbine) is as big as a shipping container and was craned into place.

Ratch Australia Corporation construction director Rene Kuypers said the significant milestone capped a huge team effort.

“Reaching this construction point has involved careful planning over many months and a lot of work from a lot of people and I’d like to thank them all,” he said.

“From unloading the cargo at Cairns Port to carefully trucking the components up to Walkamin and now the crane crews erecting the components, it’s teamwork at its best.”

Mr Kuypers said more than 400 construction crew had been inducted to work on the project to date, including 130 locals and more than 20 suppliers contracted from the wider Cairns region.

Over the project’s construction phase more than 450 components will be delivered to the site. A total of 53 wind turbines will be erected, each with a capacity exceeding 3 megawatts (MW) for a total capacity of around 180MW.

Once fully operational in September 2018, Mount Emerald will be the biggest wind farm in Queensland.

The wind farm will deliver 540,000 megawatt hours of renewable energy, which is predicted to meet the annual needs of about 75,000 north Queensland homes over a 20-year period.

Powerlink’s construction of a dedicated 275kV substation to connect the wind farm to its transmission network is also underway.

World’s Cheapest Solar Power to be Generated in Mexico

Mexico is on track to generate the world’s cheapest solar power — with prices as low as 1.77¢/kWh, according to Mexico’s Centro Nacional de Control de Energía (Cenace). Mexico’s Department of Energy recently announced the companies selected to complete new renewable power projects, and the rates at which this electricity will be sold. The lowest price for solar in Mexico has been set just below that of Saudi Arabia at 1.77¢/kWh, and is expected to continue to decrease to 1¢/kWh in 2019 or sooner. In this most recent bidding round, 15 bids from eight solar and wind energy companies, including Canadian Solar, ENEL Green Power, and Mitsui, were approved in a sign that Mexico’s renewable surge is not slowing down.

The clean energy projects recently approved by Mexico will be online and selling power by 2020. These projects and others are important steps towards meeting Mexico’s goals under the Paris agreement as well as regional goals established by Mexico, the United States, and Canada. In 2016, all three countries pledged to source 50 percent of their power from renewable sources by 2025. Canada is on track to meet this goal while Mexico continues to build up its renewable portfolio. As it was when the regional pledge was made, the United States still lags behind in its transition to clean energy.

Mexico’s achievement of cheap solar energy exceeds the expectations of skeptics who believed that such a price in a country like Mexico, rather than one like wealthy Saudi Arabia, would be highly unlikely. Despite its economic challenges, Mexico is proving that affordable renewable energy is possible around the world, brightening the prospects of the Paris agreement even as the United States refuses to participate. If current trends continue, the world may soon be faced with the prospect of plentiful, clean, affordable energy, the possibilities for which are endless.

Soil Management: Key to Fighting Climate Change?

An important tool for mitigating climate change may lie beneath our feet—soil management could increase our ability to keep carbon out of the atmosphere, a new study shows.

A paper published last week in the journal Scientific Reports estimates that by altering land use practices, the top layer of soil around the globe could increase the amount of carbon stored anywhere from 0.9 to 1.85 billion metric tons per year—an amount that equals the transportation sector’s carbon emissions.

“Analyses like this help us understand the importance of soil management for reaching climate goals. The question now is: how can we unlock this potential?” Deborah Bossio, one of the study’s authors said in a statement.

Worldwide, scientists estimate that the earth’s soil contains about 2.5 trillion tons of carbon in its top three-foot layer. Agricultural activity, depending on the type, could release large amounts of carbon by disturbing the soil. Almost 50 percent of all potentially vegetated land surface has been converted to croplands, pastures and rangelands. This in turn has contributed approximately 136 peta grams of carbon to the atmosphere since the industrial revolution. For comparison, fossil fuel combustion has pumped an estimated 270 peta grams of carbon into the atmosphere, according to the study.

The good news is this study shows how land management practices are an opportunity to reverse that trend. Rotating crops, composting, zero tillage, cover cropping and agroforestry can increase soil’s potential to keep carbon out of the atmosphere.

On a per hectare basis, South Asia and North Africa hold the greatest potential for land carbon storage, while areas with the greatest opportunity for implementation now are places that already have extensive soil management, such as the U.S.

“Regenerating soil organic carbon is a foundational strategy for conservation, through which we can provide food and water sustainably and help tackle climate change,” Bassio said.

Despite this, soil management as a climate mitigation tool did not make it onto the official Bonn climate conference agenda, although it has been discussed in side events run by environmental groups.

“It’s just not a high priority in terms of all the issues faced globally by agriculture,” Jonathan Sanderman, a soil expert at the Woods Hole Research Center, told the Scientific American.

Improving food security, increasing crop yields and increasing the resilience of agriculture to the effects of climate change are the main discussion points among policy makers. However they tend to ignore the importance of land use management and what it can do to mitigate climate change.

“The beauty of carbon sequestration is if you improve your resource bases—your soil health, your soil fertility—it almost automatically comes with sequestration of carbon,” said Rolf Sommer, one of the study’s authors.
