Vinod Khosla, Silicon Valley's biggest alternative energy investor, forecast a rapid rise in cellulosic ethanol production and utility-grade solar power, while coal should fall from favor.

The legendary venture capitalist behind high-tech companies such as Sun Microsystems and Juniper Networks said backing renewable technologies has similar investment horizons to the four- to six-year cycles that computer start-ups have enjoyed.

"I would say that the technical risk in biofuels is no different than semiconductors and the market risk is also somewhat similar," Khosla said in an interview during the Reuters Biofuels Summit.

Khosla Partners, the venture fund he founded after 15 years with top firm Kleiner Perkins Caufield & Byers, has invested in more than 25 renewable energy companies ranging from ethanol technology to solar to more efficient lamps and engines.

In the interview, Khosla forecast rapid progress in the development of low-cost cellulosic ethanol fuel as an alternative to oil, fueled by a bipartisan groundswell of support by U.S. politicians and state-level regulatory change.

2007 is the year cellulosic ethanol will become a real prospect for investors, he said. By 2008, he forecast the first initial public offerings by suppliers of cellulosic ethanol technology.

"Remember, last year (cellulosic ethanol) was six to 10 years (away). Now people talk about four to six years. And my bet is (that) by the end of this year, they will talk about two to three years," Khosla said. "So we are maybe making two years of progress every year."

He forecast the rise of a global market for ethanol fuels, as production swells in places such as Brazil and Indonesia and barriers fall to importation into Europe and North America.

"I suspect tariffs will be on their way out," he said.

On the political front, Khosla said Bush has one issue in common with the new Democratic-controlled Congress - expansion of renewable energy to offset dependence on foreign oil.

The build-up to the U.S. presidential elections next year, combined with a major Supreme Court decision that could classify carbon dioxide emissions as a pollutant, are likely to be the driving forces of further regulatory changes.

"That completely changes the equation because suddenly all the states can start to regulate carbon dioxide emissions without relying on the federal government," he said.

Khosla is lukewarm on wind or residential solar power being of much value to large utilities. But he is bullish on "solar thermal" power - large arrays of solar cells installed in Southwestern deserts - which he said is attracting the attention of at least one major electric utility in the Western United States.

"Solar thermal will become much more visible. I suspect that it will be (only) 2008 before they are recognized as real utility-scale power," Khosla said.

Khosla's upbeat remarks about alternative energies contrast sharply with his views on coal.

He said Wall Street will wake up in the coming year to the risks of further investment in coal as the primary source of fuel to produce U.S. electrical power.

"Fifteen, 20 years ago people didn't think about the political risks around nuclear," Khosla said. "Coal has the same kind of risks today and they just aren't as visible."

With carbon taxes and other anti-coal measures looming, a 50-year return on investment in new plants looks doubtful.

"My bet is that, by the end of the year or early next year ... utility values will be discounted. Market caps will come down for people who are investing or are more dependent on coal. That is going to be a big financial phenomena."

Electricity demand set to reduce if UK workforce self-isolates

UK Energy Networks Coronavirus Contingency outlines ESO's lockdown electricity demand forecast, reduced industrial and commercial load, rising domestic use, Ofgem guidance needs, grid resilience, control rooms, mutual aid, and backup centers.

 

Key Points

A coordinated plan with ESO forecasts, safeguards, and mutual aid to keep power and gas services during a lockdown.

✅ ESO forecasts lower industrial use, higher domestic demand

✅ Control rooms protected; backup sites and cross-trained staff

✅ Mutual aid and Ofgem coordination bolster grid resilience

 

National Grid ESO is predicting a reduction in electricity demand, consistent with residential use trends observed during the pandemic, in the case of the coronavirus spread prompting a lockdown across the country.

Its analysis shows the reduction in commercial and industrial use would outweigh an upsurge in domestic demand, mirroring Ontario demand data seen as people stayed home, according to similar analyses.

The prediction was included in an update from the Energy Networks Association (ENA), in which it sought to reassure the public that contingency plans are in place, reflecting utility disaster planning across electric and gas networks, to ensure services are unaffected by the coronavirus spread.

The body, which represents the UK's electricity and gas network companies, said "robust measures" had been put in place to protect control rooms and contact centres, similar to staff lockdown protocols considered by other system operators, to maintain resilience. To provide additional resilience, engineers have been trained across multiple disciplines and backup centres exist should operations need to be moved if, for example, deep cleaning is required, the ENA said.

Networks also have industry-wide mutual aid arrangements, similar to grid response measures outlined in the U.S., for people and the equipment needed to keep gas and electricity flowing.

ENA chief executive, David Smith, said, echoing system reliability assurances from other markets: "The UK's electricity and gas network is one of the most reliable in the world and network operators are working with the authorities to ensure that their contingency plans are reviewed and delivered in accordance with the latest expert advice. We are following this advice closely and reassuring customers that energy networks are continuing to operate as normal for the public."

Utility Week spoke to a senior figure at one of the networks who reiterated the robust measures in place to keep the lights on, even as grid alerts elsewhere highlight the importance of contingency planning. However, they pleaded for more clarity from Ofgem and government on how its workers will be treated if the coronavirus spread becomes a pandemic in the UK.

Fixing California's electric grid is like repairing a car while driving

CAISO Clean Energy Transition outlines California's path to 100% carbon-free power by 2045, scaling renewables, battery storage, and offshore wind while safeguarding grid reliability, managing natural gas, and leveraging Western markets like EDAM.

 

Key Points

CAISO Clean Energy Transition is the plan to reach 100% carbon-free power by 2045 while maintaining grid reliability.

✅ Target: add 7 GW/year to reach 120 GW capacity by 2045

✅ Battery storage up 30x; smooths intermittent solar and wind

✅ EDAM and WEIM enhance imports, savings, and reliability

 

Mark Rothleder, Chief Operating Officer and Senior Vice President at the California Independent System Operator (CAISO), which manages roughly 80% of California’s electric grid, has expressed cautious optimism about meeting the state's ambitious clean energy targets while keeping the lights on across the grid. However, he acknowledges that this journey will not be without its challenges.

California aims to transition its power system to 100% carbon-free sources by 2045, ensuring a reliable electricity supply at reasonable costs for consumers. Rothleder, aware of the task's enormity, likens it to a complex car repair performed while the vehicle is in motion.

Recent achievements have demonstrated California's ability to temporarily sustain its grid using clean energy sources. According to Rothleder, the real challenge lies in maintaining this performance round the clock, every day of the year.

Adding thousands of megawatts of renewable energy into California’s existing 50-gigawatt system, which needs to expand to 120 gigawatts to meet the 2045 goal, poses a significant challenge, though recent grid upgrade funding offers some support for needed infrastructure. CAISO estimates that an addition of 7 gigawatts of clean power per year for the next two decades is necessary, all while ensuring uninterrupted power delivery.

While natural gas currently constitutes California's largest single source of power, Rothleder notes the need to gradually decrease reliance on it, even as it remains an operational necessity in the transition phase.

In 2023, CAISO added 5,660 megawatts of new power to the grid, with plans to integrate over 1,100 additional megawatts in the next six to eight months of 2024. Battery storage, crucial for mitigating the intermittent nature of wind and solar power, has seen substantial growth as California turns to batteries for grid support, increasing 30-fold in three years.

Rothleder emphasizes that electricity reliability is paramount, as consumers always expect power availability. He also highlights the potential of offshore wind projects to significantly contribute to California's power mix by 2045.

The offshore wind industry faces financial and supply chain challenges despite these plans. CAISO’s 20-year outlook indicates a significant increase in utility-scale solar, requiring extensive land use and wider deployment of advanced inverters for grid stability.

Addressing affordability is vital, especially as California residents face increasing utility bills. Rothleder suggests a broader energy cost perspective, encompassing utility and transportation expenses.

Despite smooth grid operations in 2023, challenges in previous years, including extreme weather-induced power outages driven by climate change, underscore the need for a robust, adaptable grid. California imports about a quarter of its power from neighbouring states and participates in the Western Energy Imbalance Market, which has yielded significant savings.

CAISO is also working on establishing an extended day-ahead electricity market (EDAM) to enhance the current energy market's success, building on insights from a Western grid integration report that supports expanded coordination.

Rothleder believes that a thoughtfully designed, diverse power system can offer greater reliability and resilience in the long run. A future grid reliant on multiple, smaller power sources such as microgrids could better absorb potential losses, ensuring a more reliable electricity supply for California.

Cape Town to Build Own Power Plants, Buy Additional Electricity

Cape Town Renewable Energy Plan targets 450+ MW via solar, wind, and battery storage, cutting Eskom reliance, lowering greenhouse gas emissions, stabilizing electricity prices, and boosting grid resilience through municipal procurement, PPAs, and city-owned plants.

 

Key Points

A municipal plan to procure over 450 MW, cut Eskom reliance, stabilize prices, and reduce Cape Town emissions.

✅ Up to 150 MW from private plants within the city

✅ 300 MW to be purchased from outside Cape Town later

✅ City financing 100-200 MW of its own generation

 

Cape Town is seeking to secure more than 450 megawatts of power from renewable sources to cut reliance on state power utility Eskom Holdings SOC Ltd., where wind procurement cuts were considered during lockdown, and reduce greenhouse gas emissions.

South Africa’s second-biggest city is looking at a range of options, including geothermal exploration in comparable markets, and expects the bulk of the electricity to be generated from solar plants, Kadri Nassiep, the city’s executive director of energy and climate change, said in an interview.

On July 14 the city of 4.6 million people released a request for information to seek funding to build its own plants. This month or next it will seek proposals for the provision of as much as 150 megawatts from privately owned plants, largely solar additions, to be built and operated within the city, he said. As much as 300 megawatts may also be purchased at a later stage from plants outside of Cape Town, according to Nassiep.

The city could secure finance to build 100 to 200 megawatts of its own generation capacity, Nassiep said. “We realized that it is important for the city to be more in control around the pricing of the power,” he added.

Power Outages

Cape Town’s foray into the securing of power from sources other than Eskom comes after more than a decade of intermittent electricity outages, while elsewhere in Africa coal projects face scrutiny from lenders, because the utility can’t meet national demand. The government last year said municipalities could find alternative suppliers.

Earlier this month Ethekwini, the municipal area that includes the city of Durban, issued a request for information for the provision of 400 megawatts of power, similar to BC Hydro’s call for power driven by EV uptake.

The City of Johannesburg will in September seek information and proposals for the construction of a 150-megawatt solar plant, reflecting moves like Ontario’s new wind and solar procurements to tackle supply gaps, 50 megawatts of rooftop solar panels and the refurbishment of an idle gas-fired plant that could generate 20 megawatts, it said in June. It will also seek information for the installation of 100 megawatts of battery storage.

Cape Town, which uses a peak of 1,800 megawatts of electricity in winter, hopes to start generating some of its own power next year, aligning with SaskPower’s 2030 renewables plan seen in Canada, according to a statement that accompanied its request for financing proposals.

Electricity Regulation With Equity & Justice For All

Energy equity in utility regulation prioritizes fair rates, clean energy access, and DERs, addressing fixed charges and energy burdens on low-income households through stakeholder engagement and public utility commission reforms.

 

Key Points

Fairly allocates clean energy benefits and rate burdens, ensuring access and protections for low-income households.

✅ Reduces fixed charges that burden low-income households

✅ Funds community participation in utility proceedings

✅ Prioritizes DERs, energy efficiency, and solar in impacted areas

 

By Kiran Julin

Pouring over the line items on your monthly electricity bill may not sound like an enticing way to spend an afternoon, but the way electricity bills are structured has a significant impact on equitable energy access and distribution. For example, fixed fees can have a disproportionate impact on low-income households. And combined with other factors, low-income households and households of color are far more likely to report losing home heating service, with evidence from pandemic power shut-offs highlighting these disparities, according to recent federal data.

Advancing Equity in Utility Regulation, a new report published by the U.S. Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab), makes a unifying case that utilities, regulators, and stakeholders need to prioritize energy equity in the deployment of clean energy technologies and resources, aligning with a people-and-planet electricity future envisioned by advocacy groups. Equity in this context is the fair distribution of the benefits and burdens of energy production and consumption. The report outlines systemic changes needed to advance equity in electric utility regulation by providing perspectives from four organizations — Portland General Electric, a utility company; the National Consumer Law Center, a consumer advocacy organization; and the Partnership for Southern Equity and the Center for Biological Diversity, social justice and environmental organizations.
 
“While government and ratepayer-funded energy efficiency programs have made strides towards equity by enabling low-income households to access energy-efficiency measures, that has not yet extended in a major way to other clean-energy technologies,” said Lisa Schwartz, a manager and strategic advisor at Berkeley Lab and technical editor of the report. “States and utilities can take the lead to make sure the clean-energy transition does not leave behind low-income households and communities of color. Decarbonization and energy equity goals are not mutually exclusive, and in fact, they need to go hand-in-hand.”

Energy bills and electricity rates are governed by state laws and utility regulators, whose mission is to ensure that utility services are reliable, safe, and fairly priced. Public utility commissions also are increasingly recognizing equity as an important goal, tool, and metric, and some customers face major changes to electric bills as reforms advance. While states can use existing authorities to advance equity in their decision-making, several, including Illinois, Maine, Oregon, and Washington, have enacted legislation over the last couple of years to more explicitly require utility regulators to consider equity.

“The infrastructure investments that utility companies make today, and regulator decisions about what goes into electricity bills, including new rate design steps that shape customer costs, will have significant impacts for decades to come,” Schwartz said.

Solutions recommended in the report include considering energy justice goals when determining the “public interest” in regulatory decisions, allocating funding for energy justice organizations to participate in utility proceedings, supporting utility programs that increase deployment of energy efficiency and solar for low-income households, and accounting for energy inequities and access in designing electricity rates, while examining future utility revenue models as technologies evolve.

The report is part of the Future of Electric Utility Regulation series that started in 2015, led by Berkeley Lab and funded by DOE, to encourage informed discussion and debate on utility trends and tackling the toughest issues related to state electric utility regulation. An advisory group of utilities, public utility commissioners, consumer advocates, environmental and social justice organizations, and other experts provides guidance.

 

Taking stock of past and current energy inequities

One focus of the report is electricity bills. In addition to charges based on usage, electricity bills usually also have a fixed basic customer charge, which is the minimum amount a household has to pay every month to access electricity. The fixed charge varies widely, from $5 to more than $20. In recent years, utility companies have sought sizable increases in this charge to cover more costs, amid rising electricity prices in some markets.

This fixed charge means that no matter what a household does to use energy more efficiently or to conserve energy, there is always a minimum cost. Moreover, low-income households often live in older, poorly insulated housing. Current levels of public and utility funding for energy-efficiency programs fall far short of the need. The combined result is that the energy burden – or percent of income needed to keep the lights on and their homes at a healthy temperature – is far greater for lower-income households.

“While all households require basic lighting, heating, cooling, and refrigeration, low-income households must devote a greater proportion of income to maintain basic service,” explained John Howat and Jenifer Bosco from the National Consumer Law Center and co-authors of Berkeley Lab’s report. Their analysis of data from the most recent U.S. Energy Information Administration’s Residential Energy Consumption Survey shows households with income less than $20,000 reported losing home heating service at a pace more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. In addition, low-income households and households of color are more likely to have to choose between paying their energy bill or paying for other necessities, such as healthcare or food.

Based on the most recent data (2015) from the U.S. Energy Information Administration (EIA), households with income less than $20,000 reported losing home heating service at a rate more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. Click on chart for larger view.

Moreover, while many of the infrastructure investment decisions that utilities make, such as whether and where to build a new power plant, often have long-term environmental and health consequences, impacted communities often are not at the table. “Despite bearing an inequitable proportion of the negative impacts of environmental injustices related to fossil fuel-based energy production and climate change, marginalized communities remain virtually unrepresented in the energy planning and decision-making processes that drive energy production, distribution, and regulation,” wrote Chandra Farley, CEO of ReSolve and a co-author of the report.


Engaging impacted communities
Each of the perspectives in the report identify a need for meaningful engagement of underrepresented and disadvantaged communities in energy planning and utility decision-making. “Connecting the dots between energy, racial injustice, economic disinvestment, health disparities, and other associated equity challenges becomes a clarion call for communities that are being completely left out of the clean energy economy,” wrote Farley, who previously served as the Just Energy Director at Partnership for Southern Equity. “We must prioritize the voices and lived experiences of residents if we are to have more equity in utility regulation and equitably transform the energy sector.”

In another essay in the report, Nidhi Thaker and Jake Wise from Portland General Electric identify the importance of collaborating directly with the communities they serve. In 2021, the Oregon Legislature passed Oregon HB 2475, which allows the Oregon Public Utility Commission to allocate ratepayer funding for organizations representing people most affected by a high energy burden, enabling them to participate in utility regulatory processes.

The report explains why energy equity requires correcting inequities resulting from past and present failures as well as rethinking how we achieve future energy and decarbonization goals. “Equity in energy requires adopting an expansive definition of the ‘public interest’ that encompasses energy, climate, and environmental justice. Energy equity also means prioritizing the deployment of distributed energy resources and clean energy technologies in areas that have been hit first and worst by the existing fossil fuel economy,” wrote Jean Su, energy justice director and senior attorney at the Center for Biological Diversity.

This report was supported by DOE’s Grid Modernization Laboratory Consortium, with funding from the Office of Energy Efficiency and Renewable Energy and the Office of Electricity.

Tracking Progress on 100% Clean Energy Targets

100% Clean Energy Targets drive renewable electricity, decarbonization, and cost savings through state policies, CCAs, RECs, and mandates, with timelines and interim goals that boost jobs, resilience, and public health across cities, counties, and utilities.

 

Key Points

Policies for cities and states to reach 100% clean power by set dates, using mandates, RECs, and interim goals.

✅ Define eligible clean vs renewable resources

✅ Mandate vs goal framework with enforcement

✅ Timelines with interim targets and escape clauses

 

“An enormous amount of authority still rests with the states for determining your energy future. So we can build these policies that will become a postcard from the future for the rest of the country,” said David Hochschild, chair of the California Energy Commission, speaking last week at a UCLA summit on state and local progress toward 100 percent clean energy.

According to a new report from the UCLA Luskin Center for Innovation, 13 states, districts and territories, as well as more than 200 cities and counties, with standout clean energy purchases by Southeast cities helping drive momentum, have committed to a 100 percent clean electricity target — and dozens of cities have already hit it.

This means that one of every three Americans, or roughly 111 million U.S. residents representing 34 percent of the population, live in a community that has committed to or has already achieved 100 percent clean electricity, including communities like Frisco, Colorado that have set ambitious targets.

“We’re going to look back on this moment as the moment when local action and state commitments began to push the entire nation toward this goal,” said J.R. DeShazo, director of the UCLA Luskin Center for Innovation.

Not all 100 percent targets are alike, however. The report notes that these targets vary based on 1) what resources are eligible, 2) how binding the 100 percent target is, and 3) how and when the target will be achieved.

These distinctions will carry a lot of weight as the policy discussion shifts from setting goals to actually meeting targets. They also have implications for communities in terms of health benefits, cost savings and employment opportunities.

 

100% targets come in different forms

One key attribute is whether a target is based on "renewable" or "clean" energy resources. Some 100 percent targets, like Hawaii’s and Rhode Island’s 2030 plan, are focused exclusively on renewable energy, or sources that cannot be depleted, such as wind, solar and geothermal. But most jurisdictions use the broader term “clean energy,” which can also include resources like large hydroelectric generation and nuclear power.

States also vary in their treatment of renewable energy certificates, used to track and assign ownership to renewable energy generation and use. Unbundled RECs allow for the environmental attributes of the renewable energy resource to be purchased separately from the physical electricity delivery.

The binding nature of these targets is also noteworthy. Seven states, as well as Puerto Rico and the District of Columbia, have passed 100 percent clean energy transition laws. Of the jurisdictions that have passed 100 percent legislation, all but one specifies that the target is a “mandate,” according to the report. Nevada is the only state to call the target a “goal.”

Governors in four other states have signed executive orders with 100 percent clean energy goals.

Target timelines also vary. Washington, D.C. has set the most ambitious target date, with a mandate to achieve 100 percent renewable electricity by 2032. Other states and cities have set deadline years between 2040 and 2050. All "100 percent" state laws, and some city and county policies, also include interim targets to keep clean energy deployment on track.

In addition, some locations have included some form of escape clause. For instance, Salt Lake City, which last month passed a resolution establishing a goal of powering the county with 100 percent clean electricity by 2030, included “exit strategies” in its policy in order to encourage stakeholder buy-in, said Mayor Jackie Biskupski, speaking last week at the UCLA summit.

“We don’t think they’ll get used, but they’re there,” she said.

Other locales, meanwhile, have decided to go well beyond 100 percent clean electricity. The State of California and 44 cities have set even more challenging targets to also transition their entire transportation, heating and cooling sectors to 100 percent clean energy sources, and proposals like requiring solar panels on new buildings underscore how policy can accelerate progress across sectors.

Businesses are simultaneously electing to adopt more clean and renewable energy. Six utilities across the United States have set their own 100 percent clean or carbon-free electricity targets. UCLA researchers did not include populations served by these utilities in their analysis of locations with state and city 100 percent clean commitments.

 

“We cannot wait”

All state and local policies that require a certain share of electricity to come from renewable energy resources have contributed to more efficient project development and financing mechanisms, which have supported continued technology cost declines and contributed to a near doubling of renewable energy generation since 2008.

Many communities are switching to clean energy in order to save money, now that the cost calculation is increasingly in favor of renewables over fossil fuels, as more jurisdictions get on the road to 100% renewables worldwide. Additional benefits include local job creation, cleaner air and electricity system resilience due to greater reliance on local energy resources.

Another major motivator is climate change. The electricity sector is responsible for 28 percent of U.S. greenhouse gas emissions, second only to transportation. Decarbonizing the grid also helps to clean up the transportation sector as more vehicles move to electricity as their fuel source.

“The now-constant threat of wildfires, droughts, severe storms and habitat loss driven by climate change signals a crisis we can no longer ignore,” said Carla Peterman, senior vice president of regulatory affairs at investor-owned utility Southern California Edison. “We cannot wait and we should not wait when there are viable solutions to pursue now.”

Prior to joining SCE on October 1, Peterman served as a member of the California Public Utilities Commission, which implements and administers renewable portfolio standard (RPS) compliance rules for California’s retail sellers of electricity. California’s target requires 60 percent of the state’s electricity to come from renewable energy resources by 2030, and all the state's electricity to come from carbon-free resources by 2045.  

 

How CCAs are driving renewable energy deployment

One way California communities are working to meet the state’s ambitious targets is through community-choice aggregation, especially after California's near-100% renewable milestone underscored what's possible, via which cities and counties can take control of their energy procurement decisions to suit their preferences. Investor-owned utilities no longer purchase energy for these jurisdictions, but they continue to operate the transmission and distribution grid for all electricity users.                           

A second paper released by the Luskin Center for Innovation in recent days examines how community-choice aggregators are affecting levels of renewable energy deployment in California and contributing to the state’s 100 percent target.

The paper finds that 19 CCAs have launched in California since 2010, growing to include more than 160 towns, cities and counties. Of those communities, 64 have a 100 percent renewable or clean energy policy as their default energy program.

Because of these policies, the UCLA paper finds that “CCAs have had both direct and indirect effects that have led to increases in the clean energy sold in excess of the state’s RPS.”

From 2011 to 2018, CCAs directly procured 24 terawatt-hours of RPS-eligible electricity, 11 TWh of which have been voluntary or in excess of RPS compliance, according to the paper.

The formation of CCAs has also had an indirect effect on investor-owned utilities. As customers have left investor-owned utilities to join CCAs, the utilities have been left holding contracts for more renewable energy than they need to comply with California’s clean energy targets, amid rising solar and wind curtailments that complicate procurement decisions. UCLA researchers estimate that this indirect effect of CCA formation has left IOUs holding 13 terawatt-hours in excess of RPS requirements.

The paper concludes that CCAs have helped to accelerate California’s ability to meet state renewable energy targets over the past decade. However, the future contributions of CCAs to the RPS are more uncertain as communities make new power-purchasing decisions and utilities seek to reduce their excess renewable energy contracts.

“CCAs offer a way for communities to put their desire for clean energy into action. They're growing fast in California, one of only eight states where this kind of mechanism is allowed," said UCLA's Kelly Trumbull, an author of the report. "State and federal policies could be reformed to better enable communities to meet local demand for renewable energy.”

Enel kicks off 90MW Spanish wind build

Enel Green Power España Aragon wind farms advance Spain's renewable energy transition, with 90MW under construction in Teruel, Endesa investment of €88 million, 25-50MW turbines, and 2017 auction-backed capacity enhancing grid integration and clean power.

 

Key Points

They are three Teruel wind projects totaling 90MW, part of Endesa's 2017-awarded plan expanding Spain's clean energy.

✅ 90MW across Sierra Costera I, Allueva, and Sierra Pelarda

✅ €88m invested; 14+7+4 turbines; Endesa-led build in Teruel

✅ Part of 2017 tender: 540MW wind, 339MW solar, nationwide

 

Enel Green Power Espana, part of Enel's wind projects worldwide, has started constructing three wind farms in Aragon, north-east Spain, which are due online by the end of the year.

The projects, all situated in the Teruel province, are worth a total investment of €88 million.

The biggest of the facilities, Sierra Costera I, will have a 50MW and will feature 14 turbines.

The wind farm is spread across the municipalities of Mezquita de Jarque, Fuentes Calientes, Canada Vellida and Rillo.

The Allueva wind facility will feature seven turbines and will exceed 25MW.

Sierra Pelarda, in Fonfria, will have four turbines and a capacity of 15MW, as advances in offshore wind turbine technology continue to push scale elsewhere.

The projects bring the total number of wind farms that Enel Green Power Espana has started building in the Teruel province to six, equal to an overall capacity of 218MW.

Endesa chief executive Jose Bogas said: “These plants mark the acceleration on a new wave of growth in the renewable energy space that Endesa is committed to pursue in the next years, driving the energy transition in Spain.”

The six wind farms under construction in Teruel are part of the 540MW that Enel Green Power Espana was awarded in the Spanish government's renewable energy tender held in May 2017.

In Aragon, the company will invest around €434 million euros, reflecting broader European wind power investment trends in recent years, to build 13 wind farms with a total installed capacity of more than 380MW.

The remaining 160MW of wind capacity will be located in Andalusia, Castile-Leon, Castile La Mancha and Galicia, even as some Spanish turbine factories closed during pandemic restrictions.

Enel Green Power Espana was also awarded 339MW of solar capacity in the Spanish government's auction held in July 2017, while other Spanish developers advance CSP projects abroad in markets like Chile.

Once all wind and solar under the 2017 tender are complete they will boost the company’s capacity by around 52%.
