North Central Energy Facilities deliver 1,484 MW of renewable power in Oklahoma, uniting Invenergy, GE Renewable Energy, and AEP with the Traverse, Maverick, and Sundance wind farms, 531 turbines, grid-scale clean energy, and regional decarbonization.

Key Points

A 1,484 MW trio of Oklahoma wind farms by Invenergy with GE turbines, owned by AEP to supply regional customers.

✅ 1,484 MW capacity from 531 GE 2 MW platform turbines

✅ Largest single-phase wind farm: 998 MW Traverse

✅ Owned by AEP subsidiaries SWEPCO and PSO

Invenergy, the largest privately held global developer, owner and operator of sustainable energy solutions and GE Renewable Energy, today announced commercial operations for the 998-megawatt Traverse Wind Energy Center, the largest wind farm constructed in a single phase in North America, reflecting broader growth such as Enel's 450 MW project announced recently.

Located in north central Oklahoma, Traverse joins the operational 199-megawatt Sundance Wind Energy Center and the 287-megawatt Maverick Wind Energy Center, as the last of three projects developed by Invenergy for American Electric Power (AEP) to reach commercial operation, amid investor activity like WEC Energy's Illinois stake in wind assets this year. These projects make up the North Central Energy Facilities and have 531 GE turbines with a combined capacity of 1,484 megawatts, making them collectively among the largest wind energy facilities globally, even as new capacity comes online such as TransAlta's 119 MW addition in the US.

"This is a moment that Invenergy and our valued partners at AEP, GE Renewable Energy, and the gracious members of our home communities in Oklahoma have been looking forward to," said Jim Shield, Senior Executive Vice President and Development Business Leader at Invenergy, reflecting broader momentum as projects like Building Energy project begin operations nationwide. "With the completion of Traverse and with it the North Central Energy Facilities, we're proud to further our commitment to responsible, clean energy development and to advance our mission to build a sustainable world."

The North Central Energy Facilities represent a $2 billion capital investment in north central Oklahoma, mirroring Iowa wind investments that spur growth, directly investing in the local economy through new tax revenues and lease payments to participating landowners and will generate enough electricity to power 440,000 American homes.

"GE was honored to work with Invenergy on this milestone wind project, continuing our long-standing partnership," said Steve Swift, Global Commercial Leader for GE's Onshore Wind business, a view reinforced by projects like North Carolina's first wind farm coming online. "Wind power is a key element of driving decarbonization, and a dependable and affordable energy option here in the US and around the world. GE's 2 MW platform turbines are ideally suited to bring reliable and sustainable renewable energy to the region for many years to come."

AEP's subsidiaries Southwestern Electric Power Company (SWEPCO) and Public Service Company of Oklahoma (PSO) assumed ownership of the three wind farms upon start of commercial operations, alongside emerging interstate delivery efforts like Wyoming-to-California wind plans, to serve their customers in Arkansas, Louisiana and Oklahoma.

Nova Scotia Biomass Electricity Policy increases dispatchable renewable generation from Port Hawkesbury and Brooklyn Energy, raising MWh output while critics cite clearcutting, carbon emissions, high costs to ratepayers, and delays replacing Muskrat Falls hydro.

Key Points

Policy directing utilities to maximize biomass power as dispatchable renewable supply during hydro delays.

✅ Port Hawkesbury biomass output up 35% year over year

✅ Brooklyn Energy used as dispatchable renewable supply

✅ Critics cite clearcutting, emissions, high ratepayer costs

A boiler owned by Nova Scotia Power on the grounds of the Port Hawkesbury paper plant, whose discount power rate request has drawn attention, is burning 35% more woody biomass this year than last. 

The year-to-date figures show 126,810 megawatt hours (MWh) of electricity was generated over the first nine months of 2021 compared to 93,934 MWh for the same period in 2020 and 65,891 MWh in 2019. 

The information is contained in monthly fuel cost reports Nova Scotia Power must make to the Utility and Review Board, which regulates how much consumers ultimately pay for electricity and has received a call for major grid changes in Nova Scotia.

Burning biomass  — which includes everything from low-grade pulpwood to bark, shavings, and wood chip waste from sawmills — for the purpose of generating electricity is only about 22% efficient, even as some coal stations have switched to biomass abroad. Nova Scotia Power’s boiler at Port Hawkesbury supplies about 3% of the total electricity used in the province. 

Citizens concerned about climate change have for years opposed the government classifying biomass as “renewable energy” and have echoed calls to reduce biomass use for electricity, because clearcutting, which releases carbon from the ground, remains the dominant form of harvesting on Crown and private land. That’s despite ongoing work to begin implementing 2018 recommendations from Professor Bill Lahey to move toward a more ecological approach. 

In May 2020, after it became obvious renewable hydroelectricity from Muskrat Falls was going to be delayed yet again, the McNeil government passed an Order-in-Council extending until December 2022 the deadline to generate 40% of electricity from renewable sources as it moved to increase wind and solar projects across Nova Scotia. 

To help with the shortfall, Nova Scotia Power was told to “maximize” its use of biomass at both the facility it owns in Port Hawkesbury and another one in Brooklyn owned by its parent company, Emera.

In a letter to Nova Scotia Power dated May 15, then-Energy Minister Derek Mombourquette, amid debate over independent energy planning, added: “Nova Scotia Power shall also maximize the use of dispatchable renewable electricity from its own facilities, as well as those of renewable electricity power producers in Nova Scotia (excluding COMFIT generation sources).” 

By definition, “dispatchable” excludes wind and hydro sources, which are not available 24/7, though a new attempt to harness the Bay of Fundy's tides is underway. Nova Scotia Power claims the only “dispatchable renewable electricity power producer” in the province is Brooklyn Energy, the 35 MW biomass plant near Liverpool. 

The government capped at $7 million a year how much electricity Nova Scotia Power could buy from its affiliate company. Critics of the deal — such as auditors hired by the regulator and the province’s consumer advocate — say electricity generated by Brooklyn is the most expensive power and question why the province would burden ratepayers with its purchase.

The answer became apparent in September 2020 when then-Intergovernmental Affairs Minister Kelliann Dean appeared before the legislature’s standing committee on Natural Resources and Economic Development to praise the Order-in-Council for helping rescue the forestry industry four months after the closure of the Northern Pulp mill. 

“The change to Renewable Energy Standards (May,2020) is enabling Nova Scotia Power to generate more electricity from wood chips and sawmill residuals by operating two biomass plants at capacity until electricity from Muskrat Falls comes onstream,” she said. “We are using all the policy levers at our disposal to support the sector.”

Nova Scotia Power is not required to report to the UARB how much electricity is being produced or how much biomass is being burned at Brooklyn Energy. The company pleads “commercial confidentiality” when asked by The Halifax Examiner. 

Nova Scotia Power does report how much it spends each month to buy power from independent producers — a small group which includes Brooklyn but excludes all wind farms. That dollar amount has also increased over the past year — from $15.9 million for 10 months ending October 2020 compared to $23.3 million for 10 months ending October 2021. Unfortunately, the lack of transparency makes it impossible to know exactly how much of that increase is attributable to purchasing more biomass.

Radio silence
The current Minister of Natural Resources and Renewable Energy ,Tory Rushton, has the authority to reduce the amount of biomass being burned to generate electricity and by extension, the rate of clearcutting.

With a stroke of the pen, the PC government of Tim Houston could issue another Order-in-Council capping the amount of metric tonnes that could be used in the boilers, or, direct Nova Scotia Power to use biomass only when it is the most economical fuel choice. 

But so far, Rushton has not responded to the Halifax Examiner’s question about whether he intends to make any change to stop “maximizing” the use of biomass to produce electricity.

 The Examiner isn’t the only one pushing the Minister for answers to difficult issues. At noon today, Citizens opposed to a controversial clearcut on Crown land near Rocky Point Lake in Digby County will stage a demonstration outside the Department of Natural Resources and Renewable Energy on Hollis Street. The protest led by members of Extinction Rebellion and the Healthy Forest Coalition is to pressure the government to take action to protect the habitat of the mainland moose, an endangered species that ranges overs the Crown land currently being cut by the Westfor consortium.

EVI-Pro Lite EV Load Forecasting helps utilities model EV charging infrastructure, grid load shapes, and resilient energy systems, factoring home, workplace, and public charging behavior to inform planning, capacity upgrades, and flexible demand strategies.

Key Points

A NREL tool projecting EV charging demand and load shapes to help utilities plan the grid and right-size infrastructure.

✅ Visualizes weekday/weekend EV load by charger type.

✅ Tests home, workplace, and public charging access scenarios.

✅ Supports utility planning, demand flexibility, and capacity upgrades.

As electric vehicles (EVs) continue to grow in popularity, utilities and community planners are increasingly focused on building resilient energy systems that can support the added electric load from EV charging, including a possible EV-driven demand increase across the grid.

But forecasting the best ways to adapt to increased EV charging can be a difficult task as EV adoption will challenge state power grids in diverse ways. Planners need to consider when consumers charge, how fast they charge, and where they charge, among other factors.

To support that effort, researchers at the National Renewable Energy Laboratory (NREL) have expanded the Electric Vehicle Infrastructure Projection (EVI-Pro) Lite tool with more analytic capabilities. EVI-Pro Lite is a simplified version of EVI-Pro, the more complex, original version of the tool developed by NREL and the California Energy Commission to inform detailed infrastructure requirements to support a growing EV fleet in California, where EVs bolster grid stability through coordinated planning.

EVI-Pro Lite’s estimated weekday electric load by charger type for El Paso, Texas, assuming a fleet of 10,000 plug-in electric vehicles, an average of 35 daily miles traveled, and 50% access to home charging, among other variables, as well as potential roles for vehicle-to-grid power in future scenarios. The order of the legend items matches the order of the series stacked in the chart.

Previously, the tool was limited to letting users estimate how many chargers and what kind of chargers a city, region, or state may need to support an influx of EVs. In the added online application, those same users can take it a step further to predict how that added EV charging will impact electricity demand, or load shapes, in their area at any given time and inform grid coordination for EV flexibility strategies.

“EV charging is going to look different across the country, depending on the prevalence of EVs, access to home charging, and the kind of chargers most used,” said Eric Wood, an NREL researcher who led model development. “Our expansion gives stakeholders—especially small- to medium-size electric utilities and co-ops—an easy way to analyze key factors for developing a flexible energy strategy that can respond to what’s happening on the ground.”

Tools to forecast EV loads have existed for some time, but Wood said that EVI-Pro Lite appeals to a wider audience, including planners tracking EVs' impact on utilities in many markets. The tool is a user-friendly, free online application that displays a clear graphic of daily projected electric loads from EV charging for regions across the country.

After selecting a U.S. metropolitan area and entering the number of EVs in the light-duty fleet, users can change a range of variables to see how they affect electricity demand on a typical weekday or weekend. Reducing access to home charging by half, for example, results in higher electric loads earlier in the day, although energy storage and mobile charging can help moderate peaks in some cases. That is because under such a scenario, EV owners might rely more on public or workplace charging instead of plugging in at home later in the evening or at night.

“Our goal with the lite version of EVI-Pro is to make estimating loads across thousands of scenarios fast and intuitive,” Wood said. “And if utilities or stakeholders want to take that analysis even deeper, our team at NREL can fill that gap through partnership agreements, too. The full version of EVI-Pro can be tailored to develop detailed studies for individual planners, agencies, or utilities.”

Germany Hydrogen Fuel Cell Market gains momentum as policy, mobility, and R&D align; National Hydrogen Strategy, regulatory frameworks, and cost-of-ownership advances boost heavy transport, while Europe races Asia amid battery-electric competition and infrastructure scale-up.

Key Points

It is Germany and Europe's hydrogen fuel cell ecosystem across policy, costs, R&D, and mobility and freight deployments.

✅ Policy support via National Hydrogen Strategy and tax incentives

✅ TCO parity improves for heavy transport vs other low-emission tech

✅ R&D targets higher temps, compactness for road, rail, sea, air

In a new report examining the status of the German and European hydrogen fuel cell markets, the German government-backed National Platform Future of Mobility (NPM) says there is “a good chance that fuel cell technology can achieve a break-through in mobile applications,” even as the age of electric cars accelerates across markets.

However, Europe must catch up with Asian countries, it adds, even as a push for electricity shapes climate policy. For Germany and Europe to take on a leading role in fuel cell technologies, their industries need to be strengthened and sustainably developed, the report finds. In its paper, the NPM Working Group 4 – which aims to secure Germany as a place for mobility, battery cell production, recycling, training and qualification – states that the “chances of fuel cell technology achieving a break-through in the automotive industry – even in Europe – are better than ever,” echoing recent remarks from BMW's chief about hydrogen's appeal.

The development, expansion and use of the technology in various applications are now supported by “a significantly modified regulatory framework and new political ambitions, as stipulated in the National Hydrogen Strategy,” while updated forecasts show e-mobility driving electricity demand in Germany, the report stresses. In terms of cost of ownership, “hydrogen solutions can hold their own compared to other technologies” and there are “many promising developments in the transport sector, especially in heavy transport.”

If research and development efforts can help optimise installation space and weight as well as increase the operating temperature of fuel cells, hydrogen solutions can also become attractive for maritime, rail and air transport, even as other electrochemical approaches, such as flow battery cars, progress, the report notes. Tax incentives -- such as the Renewable Energy Sources Act (EEG) surcharge exemption for green hydrogen -- can contribute to the technology’s appeal, it adds.

Fuel cell drives are often seen as a way to decarbonise certain areas of transport, such as heavy trucks. However, producing the hydrogen in a sustainable way consumes a lot of renewable electricity that power companies must supply in other sectors, and experts say electricity vs hydrogen trade-offs favor battery-electric trucks because they are much cheaper to run than other low-emission technologies, including fuel cells.

Ukraine Wind Energy Resilience shields the grid with wind power along the Black Sea, dispersing turbines to withstand missile attacks, accelerate clean energy transition, aid EU integration, and strengthen energy security and rapid recovery.

Key Points

A strategy in Ukraine using wind farms to harden the grid, ensure clean power, and speed recovery from missile strikes.

✅ Distributed turbines reduce single-point-of-failure risk

✅ Faster repair of substations and lines than power plants

✅ Supports EU-aligned clean energy and grid security goals

The giants catch the wind with their huge arms, helping to keep the lights on in Ukraine — newly built windmills, on plains along the Black Sea.

In 15 months of war, Russia has launched countless missiles and exploding drones at power plants, hydroelectric dams and substations, trying to black out as much of Ukraine as it can, as often as it can, even amid talk of limiting attacks on energy sites that has surfaced, in its campaign to pound the country into submission.

The new Tyligulska wind farm stands only a few dozen miles from Russian artillery, but Ukrainians say it has a crucial advantage over most of the country’s grid, helping stabilize the system even as electricity exports have occasionally resumed under fire.

A single, well-placed missile can damage a power plant severely enough to take it out of action, but Ukrainian officials say that doing the same to a set of windmills — each one tens of meters apart from any other — would require dozens of missiles. A wind farm can be temporarily disabled by striking a transformer substation or transmission lines, but these are much easier to repair than power plants.

“It is our response to Russians,” said Maksym Timchenko, CEO of DTEK Group, the company that built the turbines in the southern Mykolaiv region — the first phase of what is planned as Eastern Europe’s largest wind farm. “It is the most profitable and, as we know now, most secure form of energy.”

Ukraine has had laws in place since 2014 to promote a transition to renewable energy, both to lower dependence on Russian energy imports, with periods when electricity exports resumed to neighbors, and because it was profitable. But that transition still has a long way to go, and the war makes its prospects, like everything else about Ukraine’s future, murky.

In 2020, 12% of Ukraine’s electricity came from renewable sources — barely half the percentage for the European Union. Plans for the Tyligulska project call for 85 turbines producing up to 500 megawatts of electricity. That’s enough for 500,000 apartments — an impressive output for a wind farm, but less than 1% of the country’s prewar generating capacity.

After the Kremlin began its full-scale invasion of Ukraine in February 2022, the need for new power sources became acute, prompting deliveries such as a mobile gas turbine power plant to bolster capacity. Russia has bombarded Ukraine’s power plants and cut off delivery of the natural gas that fueled some of them.

Russian occupation forces have seized a large part of the country’s power supply, and Russia has built power lines to reactivate the Zaporizhzhia plant in occupied territory, ensuring that its output does not reach territory still held by Ukraine. They hold the single largest generator, the 5,700-megawatt Zaporizhzhia Nuclear Power Plant, which has been damaged repeatedly in fighting and has stopped transmitting energy to the grid, with UN inspectors warning of mines at the site during recent visits. They also control 90% of Ukraine’s renewable energy plants, which are concentrated in the southeast.

The postwar recovery plans Ukraine has presented to supporters including the European Union, which it hopes to join, feature a major new commitment to clean energy, even as a controversial proposal on Ukraine’s nuclear plants continues to stir debate.

Alberta Renewable Energy Boom highlights corporate investments, power purchase agreements, wind and solar capacity gains, grid decarbonization, and job growth, adding 2 GW and $3.7B construction since 2019 in an open electricity market.

Key Points

Alberta's PPA-driven wind and solar surge adds 2 GW, cuts grid emissions, creates jobs, and accelerates private builds.

✅ 2 GW added since 2019 via corporate PPAs

✅ Open electricity market enables direct deals

✅ Strong wind and solar resources boost output

Alberta has seen a massive increase in corporate investment in renewable energy since 2019, and capacity from those deals is set to increase output by two gigawatts —  enough to power roughly 1.5 million homes. 

“Our analysis shows $3.7 billion worth of renewables construction by 2023 and 4,500 jobs,” Nagwan Al-Guneid, the director of Business Renewables Centre Canada, says. 

The centre is an initiative of the environmental think tank Pembina Institute and provides education and guidance for companies looking to invest in renewable energy or energy offsets across Canada. Its membership is made up of renewable energy companies.

The addition of two gigawatts is over two times the amount of renewable energy added to the grid between 2010 and 2017, according to the Canadian Energy Regulator.

“This is driven directly by what we call power purchase agreements,” Al-Guneid says. “We have companies from across the country coming to Alberta.”

So far this year, 191 megawatts of renewable energy will be added through purchase agreements, according to the Business Renewables Centre, as diversified energy sources can make better projects overall.

Alberta’s electricity system is unique in Canada — an open market where companies can ink deals directly with private power producers to sell renewable energy and buy a set amount of electricity produced each year, either for use or for offset credits. The financial security provided by those contracts helps producers build out more renewable projects without market risks. Purchasers get cheap renewable energy or credits to meet internal or external emissions goals. 

It differs from other provinces, many of which rely on large hydro capacity and where there is a monopoly, often government-owned, on power supply. 

In those provinces, investment in renewables largely depends on whether the company with the monopoly is in a buying mood, says Blake Shaffer, an economics professor at the University of Calgary who studies electricity markets. 

That’s not the case in Alberta, where the only real regulatory hurdle is applying to connect a project to the grid.

“Once that’s approved, you can just go ahead and build it, and you can sell it,” Shaffer says.

That sort of flexibility has attracted some big investments, including two deals with Amazon in 2021 to purchase 455 megawatts worth of solar power from Calgary-based Greengate Power. There are also big investments from oil companies looking to offset emissions.

The investments are allowing Alberta to decarbonize its grid, largely with the backing of the private sector. 

Shaffer says Alberta is the “renewables capital in Canada,” a powerhouse in both green and fossil energy by many measures.

“That just shocks people because of course their association with Alberta is nothing about renewables, but oil and gas,” Shaffer says. “But it really is the investment centre for renewables in the entire country right now.”

Alberta has ‘embarrassing’ riches in wind energy and solar power
It’s not just the market that is driving Alberta’s renewables boom. According to Shaffer there are three other key factors: an embarrassment of wind and solar riches, the need to transition away from a traditionally dirty, coal-reliant grid and the current high costs of energy. 

Shaffer says the strong and seemingly non-stop winds coming off the foothills of the Rockies in the southwest of the province mean wind power is increasingly competitive and each turbine produces more energy compared to other areas. The same is true for solar, with an abundance of sunny days.

“Southern Alberta and southern Saskatchewan have the best solar insolation,” he says. “You put a panel in Vancouver, or you put a panel in Medicine Hat, and you’re gonna get about 50 per cent more energy out of that panel in Medicine Hat, and they’re gonna cost you the same.”

The spark that set off the surge in investments wasn’t strictly an open-market mechanism. Under the previous NDP government, the province brought in a program that allowed private producers to compete for government contracts, with some solar facilities contracted below natural gas demonstrating cost advantages.

The government agreed to a certain price and the producers were then allowed to sell their electricity on the open market. If the price dropped below what was guaranteed, the province would pay the difference. If, however, the price was higher, the developers would pay the difference to the government.
