Renewable electricity powered California just shy of 100% for the first time in history

ABO Wind Tunisia 10MW Solar Project will build a photovoltaic park in Gabes with a STEG PPA, fixed tariff, 2,500 m grid connection, producing 18 million kWh annually, targeted for 2020 commissioning with local partners.

Key Points

A 10MW photovoltaic park in Gabes with a 20-year STEG PPA and fixed tariff, slated for 2020 commissioning.

✅ 18 million kWh/year; 2,500 m grid tie, 20-year fixed tariff

✅ Electricity supplied to STEG under PPA; 2020 commissioning

✅ Located in Gabes; built with local partners, 10MW capacity

ABO Wind has received a permit and a tariff for a 10MW photovoltaic project in Tunisia, amid global activity such as Spain's 90MW wind project now underway, which it plans to build and commission in 2020.

The solar park, in the governorate of Gabes, is 400km south of the country’s capital Tunis and aligns with renewable funding initiatives seen across developing markets.

The developer said it plans to build the project next year in close cooperation with local partners, as regional markets from North Africa to the Gulf expand, with Saudi Arabia boosting wind capacity as well.

ABO Wind department head Nicolas Konig said: “The solar park will produce more than 18 million kilowatt hours of electricity per year and will feed it into the grid at a distance of 2500 metres.”

The developer will conclude an electricity supply contract with the state-owned energy supplier (Societe tunisienne de l’electricite et du gaz (STEG), which will provide a fixed remuneration over 20 years, a model echoed by Germany's wind-solar tender for the electricity fed into the grid.

Earlier this year, ABO Wind had already secured a tariff for a wind farm with a capacity of 30MW in a tender, 35km south-east of Tunis, underscoring Tunisia's wind investments under its long-term plan.

The company is working on half a dozen Tunisian wind and solar projects, as institutions like the World Bank support wind growth in developing countries.

“We are making good progress on our way to assemble a portfolio of several ready-to-build wind and solar projects attractive to investors, as Saudi clean energy targets continue to expand globally,” said ABO Wind general manager responsible for international business development Patrik Fischer.

San Francisco Battery-Electric Ferries will deliver zero-emission, high-speed passenger service powered by Wartsila electric propulsion, EPMS, IAS, batteries, and shore power, advancing maritime decarbonization under the REEF program and USCG Subchapter T standards.

Key Points

They are the first US zero-emission high-speed passenger ferries using integrated electric propulsion and shore power

✅ Dual 625 kW motors enable up to 24-knot service speeds

✅ EPMS, IAS, DC hub, and shore power streamline operations

✅ Built to USCG Subchapter T for safety and compliance

Wartsila, a global leader in sustainable marine technology, has been selected to supply the electric propulsion system for the United States' first fully battery-electric, zero-emission high-speed passenger ferries. This significant development marks a pivotal step in the decarbonization of maritime transport, aligning with California's ambitious environmental goals, including recent clean-transport investments across ports and corridors.

A Leap Toward Sustainable Maritime Transport

The project, commissioned by All American Marine (AAM) on behalf of San Francisco Bay Ferry, involves the construction of three 150-passenger ferries, reflecting broader U.S. advances like the Washington State Ferries hybrid upgrade now underway. These vessels will operate on new routes connecting the rapidly developing neighborhoods of Treasure Island and Mission Bay to downtown San Francisco. The ferries are part of the Rapid Electric Emission Free (REEF) Ferry Program, a comprehensive initiative by San Francisco Bay Ferry to transition its fleet to zero-emission propulsion technology. The first vessel is expected to join the fleet in early 2027.

Wärtsilä’s Role in the Project

Wärtsilä's involvement encompasses the supply of a comprehensive electric propulsion system, including the Energy and Power Management System (EPMS), integrated automation system (IAS), batteries, DC hub, transformers, electric motors, and shore power supply. This extensive scope underscores Wärtsilä’s expertise in providing integrated solutions for emission-free marine transportation. The company's extensive global experience in developing and supplying integrated systems and solutions for zero-emission high-speed vessels, as seen with electric ships on the B.C. coast operating today, was a key consideration in the selection process.

Technical Specifications of the Ferries

The ferries will be 100 feet (approximately 30 meters) in length, with a beam of 26 feet and a draft of 5.9 feet. Each vessel will be powered by dual 625-kilowatt electric motors, enabling them to achieve speeds of up to 24 knots. The vessels will be built to U.S. Coast Guard Subchapter T standards, ensuring compliance with stringent safety regulations.

Environmental and Operational Benefits

The transition to battery-electric propulsion offers numerous environmental and operational advantages. Electric ferries produce zero emissions during operation, as demonstrated by Berlin's electric ferry deployments, significantly reducing the carbon footprint of maritime transport. Additionally, electric propulsion systems are generally more efficient and require less maintenance compared to traditional diesel engines, leading to lower operational costs over the vessel's lifespan.

Broader Implications for Maritime Decarbonization

This project is part of a broader movement toward sustainable maritime transport in the United States. San Francisco Bay Ferry has also approved the purchase of two larger 400-passenger battery-electric ferries for transbay routes, further expanding its commitment to zero-emission operations. The agency has secured approximately $200 million in funding from local, state, and federal sources, echoing infrastructure bank support seen in B.C., to support these initiatives, including vessel construction and terminal electrification.

Wartsila’s involvement in this project highlights the company's leadership in the maritime industry's transition to sustainable energy solutions, including hybrid-electric pathways like BC Ferries' new hybrids now in service. With a proven track record in supplying integrated systems for zero-emission vessels, Wärtsilä is well-positioned to support the global shift toward decarbonized maritime transport.

As the first fully battery-electric high-speed passenger ferries in the United States, these vessels represent a significant milestone in the journey toward sustainable and environmentally responsible maritime transportation, paralleling regional advances such as the Kootenay Lake electric-ready ferry entering service. The collaboration between Wärtsilä, All American Marine, and San Francisco Bay Ferry exemplifies the collective effort required to realize a zero-emission future for the maritime industry.

The deployment of these battery-electric ferries in San Francisco Bay not only advances the city's environmental objectives but also sets a precedent for other regions to follow. With continued innovation and collaboration, the maritime industry can look forward to a future where sustainable practices are the standard, not the exception.

EV Grid Capacity Management shows how smart charging, load balancing, and off-peak pricing align with utility demand response, DC fast charging networks, and renewable integration to keep national electricity infrastructure reliable as EV adoption scales

Key Points

EV Grid Capacity Management schedules charging and balances load to keep EV demand within utility capacity.

✅ Off-peak pricing and time-of-use tariffs shift charging demand.

✅ Smart chargers enable demand response and local load balancing.

✅ Gradual EV adoption allows utilities to plan upgrades efficiently.

One of the most frequent concerns you will see from electric vehicle haters is that the electricity grid can’t possibly cope with all cars becoming EVs, or that EVs will crash the grid entirely. However, they haven’t done the math properly. The grids in most developed nations will be just fine, so long as the demand is properly management. Here’s how.

The biggest mistake the social media keyboard warriors make is the very strange assumption that all cars could be charging at once. In the UK, there are currently 32,697,408 cars according to the UK Department of Transport. The UK national grid had a capacity of 75.8GW in 2020. If all the cars in the UK were EVs and charging at the same time at 7kW (the typical home charger rate), they would need 229GW – three times the UK grid capacity. If they were all charging at 50kW (a common public DC charger rate), they would need 1.6TW – 21.5 times the UK grid capacity. That sounds unworkable, and this is usually the kind of thinking behind those who claim the UK grid can't cope with EVs.

What they don’t seem to realize is that the chances of every single car charging all at once are infinitesimally low. Their arguments seem to assume that nobody ever drives their car, and just charges it all the time. If you look at averages, the absurdity of this position becomes particularly clear. The distance each UK car travels per year has been slowly dropping, and was 7,400 miles on average in 2019, again according to the UK Department of Transport. An EV will do somewhere between 2.5 and 4.5 miles per kWh on average, so let’s go in the middle and say 3.5 miles. In other words, each car will consume an average of 2,114kWh per year. Multiply that by the number of cars, and you get 69.1TWh. But the UK national grid produced 323TWh of power in 2019, so that is only 21.4% of the energy it produced for the year. Before you argue that’s still a problem, the UK grid produced 402TWh in 2005, which is more than the 2019 figure plus charging all the EVs in the UK put together. The capacity is there, and energy storage can help manage EV-driven peaks as well.

Let’s do the same calculation for the USA, where an EV boom is about to begin and planning matters. In 2020, there were 286.9 million cars registered in America. In 2020, while the US grid had 1,117.5TW of utility electricity capacity and 27.7GW of solar, according to the US Energy Information Administration. If all the cars were EVs charging at 7kW, they would need 2,008.3TW – nearly twice the grid capacity. If they charged at 50kW, they would need 14,345TW – 12.8 times the capacity.

However, in 2020, the US grid generated 4,007TWh of electricity. Americans drive further on average than Brits – 13,500 miles per year, according to the US Department of Transport’s Federal Highway Administration. That means an American car, if it were an EV, would need 3,857kWh per year, assuming the average efficiency figures above. If all US cars were EVs, they would need a total of 1,106.6TWh, which is 27.6% of what the American grid produced in 2020. US electricity consumption hasn’t shrunk in the same way since 2005 as it has in the UK, but it is clearly not unfeasible for all American cars to be EVs. The US grid could cope too, even as state power grids face challenges during the transition.

After all, the transition to electric isn’t going to happen overnight. The sales of EVs are growing fast, with for example more plug-ins sold in the UK in 2021 so far than the whole of the previous decade (2010-19) put together. Battery-electric vehicles are closing in on 10% of the market in the UK, and they were already 77.5% of new cars sold in Norway in September 2021. But that is new cars, leaving the vast majority of cars on the road fossil fuel powered. A gradual introduction is essential, too, because an overnight switchover would require a massive ramp up in charge point installation, particularly devices for people who don’t have the luxury of home charging. This will require considerable investment, but could be served by lots of chargers on street lamps, which allegedly only cost £1,000 ($1,300) each to install, usually with no need for extra wiring.

This would be a perfectly viable way to provide charging for most people. For example, as I write this article, my own EV is attached to a lamppost down the street from my house. It is receiving 5.5kW costing 24p (32 cents) per kWh through SimpleSocket, a service run by Ubitricity (now owned by Shell) and installed by my local London council, Barnet. I plugged in at 11am and by 7.30pm, my car (which was on about 28% when I started) will have around 275 miles of range – enough for a couple more weeks. It will have cost me around £12 ($16) – way less than a tank of fossil fuel. It was a super-easy process involving the scanning of a QR code and entering of a credit card, very similar to many parking systems nowadays. If most lampposts had one of these charging plugs, not having off-street parking would be no problem at all for owning an EV.

With most EVs having a range of at least 200 miles these days, and the average mileage per day being 20 miles in the UK (the 7,400-mile annual figure divided by 365 days) or 37 miles in the USA, EVs won’t need charging more than once a week or even every week or two. On average, therefore, the grids in most developed nations will be fine. The important consideration is to balance the load, because if too many EVs are charging at once, there could be a problem, and some regions like California are looking to EVs for grid stability as part of the solution. This will be a matter of incentivizing charging during off-peak times such as at night, or making peak charging more expensive. It might also be necessary to have the option to reduce charging power rates locally, while providing the ability to prioritize where necessary – such as emergency services workers. But the problem is one of logistics, not impossibility.

There will be grids around the world that are not in such a good place for an EV revolution, at least not yet, and some critics argue that policies like Canada's 2035 EV mandate are unrealistic. But to argue that widespread EV adoption will be an insurmountable catastrophe for electricity supply in developed nations is just plain wrong. So long as the supply is managed correctly to make use of spare capacity when it’s available as much as possible, the grids will cope just fine.

Zaporizhzhia Nuclear Plant Restart signals new high-voltage transmission lines to Mariupol, Rosatom grid integration, and IAEA-monitored safety amid occupied territory risks, cooling system shortfalls after the Kakhovka dam collapse, and disputed international law.

Key Points

A Russian plan to reconnect and possibly restart ZNPP via power lines, despite IAEA safety, cooling, and legal risks.

✅ 80 km high-voltage link toward Mariupol confirmed by imagery

✅ IAEA warns of safety risks and militarization at the site

✅ Cooling capacity limited after Kakhovka dam destruction

Russia is actively constructing new power lines to facilitate the restart of the Zaporizhzhia Nuclear Power Plant (ZNPP), Europe's largest nuclear facility, which it seized from Ukraine in 2022. Satellite imagery analyzed by Greenpeace indicates the construction of approximately 80 kilometers (50 miles) of high-voltage transmission lines and pylons connecting the plant to the Russian-controlled port city of Mariupol. This development marks the first tangible evidence of Russia's plan to reintegrate the plant into its energy infrastructure.

Strategic Importance of Zaporizhzhia Nuclear Power Plant

The ZNPP, located on the eastern bank of the Dnipro River in Enerhodar, was a significant asset in Ukraine's energy sector before its occupation. Prior to the war, the plant was connected to Ukraine's national grid, which later saw resumed electricity exports, via four 750-kilovolt lines, two of which passed through Ukrainian-controlled territory and two through areas under Russian control. The ongoing conflict has damaged these lines, complicating efforts to restore the plant's operations.

In March 2022, Russian forces captured the plant, and by 2023, all six of its reactors had been shut down. Despite this, Russian authorities have expressed intentions to restart the facility. Rosatom, Russia's state nuclear corporation, has identified replacing the power grid as one of the critical steps necessary for resuming operations, even as Ukraine pursues more resilient wind power to bolster its energy mix.

Environmental and Safety Concerns

The construction of new power lines and the potential restart of the ZNPP have raised significant environmental and safety concerns, as the IAEA has warned of nuclear risks from grid attacks in recent assessments. Greenpeace has reported that the plant's cooling system has been compromised due to the destruction of the Kakhovka Reservoir dam in 2023, which previously supplied cooling water to the plant. Currently, the plant relies on wells for cooling, which are insufficient for full-scale operations.

Additionally, the International Atomic Energy Agency (IAEA) has expressed concerns about the militarization of the plant. Reports indicate that Russian forces have established defensive positions and trenches around the facility, with mines found at ZNPP by UN inspectors, raising the risk of accidents and complicating efforts to ensure the plant's safety.

International Reactions and Legal Implications

Ukraine and the international community have condemned Russia's actions as violations of international law and Ukrainian sovereignty. Ukrainian officials have argued that the construction of power lines and the potential restart of the ZNPP constitute illegal activities in occupied territory. The IAEA has called for a ceasefire to allow for necessary safety improvements and to facilitate inspections of the plant, as a possible agreement on power plant attacks could underpin de-escalation efforts.

The United States has also expressed concerns, with President Donald Trump reportedly proposing the inclusion of the ZNPP in peace negotiations, which sparked controversy among Ukrainian and international observers, even suggesting the possibility of transferring control to American companies. However, Russia has rejected such proposals, reaffirming its intention to maintain control over the facility.

The construction of new power lines to the Zaporizhzhia Nuclear Power Plant signifies Russia's commitment to reintegrating the facility into its energy infrastructure. However, this move raises significant environmental, safety, and legal concerns, and a proposal to control Ukraine's nuclear plants remains controversial among stakeholders. The international community continues to monitor the situation closely, urging for adherence to international laws and standards to prevent potential nuclear risks.

Alberta Renewable Energy Procurement is surging as corporate PPAs drive wind and solar growth, with the Pembina Institute and the Business Renewables Centre linking buyers and developers in Alberta's energy-only market near Medicine Hat.

Key Points

A market-led approach where corporations use PPAs to secure wind and solar power from Alberta projects.

✅ Corporate PPAs de-risk projects and lock in clean power.

✅ Alberta's energy-only market enables efficient transactions.

✅ Skilled workforce supports wind, solar, legal, and financing.

Alberta has big potential when it comes to providing renewable energy, advocates say.

The Pembina Institute says the practice of corporations committing to buy renewable energy is just taking off in Canada, and Alberta has both the energy sector and the skilled workforce to provide it.

Earlier this week, a company owned by U.S. billionaire Warren Buffett announced a large new wind farm near Medicine Hat. It has a buyer for the power.

Sara Hastings-Simon, director of the Pembina's Business Renewables Centre, says this is part of a trend.

"We're talking about the practice of corporate institutions purchasing renewables to meet their own electricity demand. And this is a really well-established driver for renewable energy development in the U.S.," she said. "You may be hearing headlines like Google, Apple and others that are buying renewables and we're helping to bring this practice to Canada."

The Business Renewables Centre (BRC) is a not-for-profit working to accelerate corporate and institutional procurement of renewables in Canada. The group held its inaugural all members event in Calgary on Thursday.

Hastings-Simon says shareholders and investors are encouraging more use of solar and wind power in Canada.

"We have over 10 gigawatts of renewable energy projects in the pipeline that are ready for buyers. And so we see multinational companies coming to Canada to start to procure here, as well as Canadian companies understanding that this is an opportunity for them as well," Hastings-Simon said.

"It's really exciting to see business interests driving renewable energy development."

Hastings-Simon says renewable procurement could help dispel the narrative that it's all about oil and gas in Alberta by highlighting Alberta as a powerhouse for both green energy and fossil fuels in Canada.

She says the practice started with a handful of tech companies in the U.S. and has become more mainstream there, even as Canada remains a solar laggard to some observers, with more and more large companies wanting to reduce their energy footprint.

He says his U.S.-based organization has been working for years to speed up and expand the renewables market for companies that want to address their own sustainability.

"We try and make that a little bit easier by building out a community that can help to really reinforce each other, share lessons learned, best practices and then drive for transactions to have actual material impact worldwide," he said.

"We're really excited to be working with the Pembina group and the BRC Canada team," he said. "We feel our best value for this is just to support them with our experiences and lessons. They've been basically doing the same thing for many years helping to grow and grow and cultivate the market."

Porter says Alberta's market is more than ready.

"There are some precedent transactions already so people know it can work," he said. "The way Alberta is structured, being an energy-only market is useful. And I think that there is a strong ecosystem of both budget developers and service providers … that can really help these transactions get over the line."

As procurement ramps up, Hastings-Simon says Alberta already has the skilled workers needed to fill renewable energy jobs across the province.

"We have a lot of the knowledge that's needed, and that's everybody from the construction down through the legal and financing — all those pieces of building big projects," she said. "We are seeing increasing interest in people that want to become involved in that industry, and so there is increasing demand for training in things like solar power installation and wind technicians."

Hastings-Simon predicts an increase in demand for both the services and the workers.

"As this industry ramps up, we're going to need to have more workers that are active in those areas," she said. "So I think we can see a very nice increase — both the demand and the number of folks that are able to work in this field."

Collectively, the storage facilities will enhance grid operations, increase efficiencies and improve overall reliability for surrounding communities, with virtual power plant programs offering a model for coordinating distributed resources.

They will also provide important backup generation during power outages, a service that is becoming increasingly important with the number and intensity of storms that have recently impacted the state.

As the grid manager and operator, DEF can maximize the versatility of battery energy storage systems (BESS) to include multiple customer and electric system benefits such as balancing energy demand, managing intermittent resources, increasing energy security and deferring traditional power grid upgrades.

These benefits help reduce costs for customers and increase operational efficiencies.

The 11-megawatt (MW) Trenton lithium-based battery facility will be located 30 miles west of Gainesville in Gilchrist County. The energy storage project will continue to improve power reliability using newer technologies.

The 5.5-MW Cape San Blas lithium-based battery facility will be located approximately 40 miles southeast of Panama City in Gulf County. The project will provide additional power capacity to meet our customers' rising energy demand in the area. This project is an economical alternative to replacing distribution equipment necessary to accommodate local load growth.

The 5.5-MW Jennings lithium-based battery facility will be located 1.5 miles south of the Florida-Georgia border in Hamilton County. The project will continue to improve power reliability through energy storage as an alternative solution to installing new and more costly distribution equipment.

Currently the company plans to complete all three projects by the end of 2020.

"These battery projects provide electric system benefits that will help improve local reliability for our customers and provide significant energy services to the power grid," said Catherine Stempien, Duke Energy Florida state president. "Duke Energy Florida will continue to identify opportunities in battery storage technology which will deliver efficiency improvements to our customers."

Additional renewables projects

As part of DEF's commitment to renewables, the company is investing an estimated $1 billion to construct or acquire a total of 700 MW of cost-effective solar power facilities and 50 MW of battery storage through 2022.

Duke Energy is leading the industry deployment of battery technology, with SDG&E's Emerald Storage project underscoring broader adoption across the sector today. Last fall, the company and University of South Florida St. Petersburg unveiled a Tesla battery storage system that is connected to a 100-kilowatt (kW) solar array – the first of its kind in Florida.

This solar-battery microgrid system manages the energy captured by the solar array, situated on top of the university's parking garage, and similar low-income housing microgrid financing efforts are expanding access. The solar array was constructed three years ago through a $1 million grant from Duke Energy. The microgrid provides a backup power source during a power outage for the parking garage elevator, lights and electric vehicle charging stations. Click here to learn more.

In addition to expanding its battery storage technology and solar investments, DEF is investing in transportation electrification to support the growing U.S. adoption of electric vehicles (EV), including EV charging infrastructure, 530 EV charging stations and a modernized power grid to deliver the diverse and reliable energy solutions customers want and need.
