California Gets $500M to Upgrade Power Grid

Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.

Key Points

An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.

✅ VFSGs start engines, then generate 235Vac variable-frequency power

✅ Bleedless pressurization, electric anti-ice improve fuel efficiency

✅ Electric brakes cut hydraulic weight and simplify maintenance

The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.

When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.

What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.

Power sources

The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.

Engine starter/generators

The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.

The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.

APU starter/generators

In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.

The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.

The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.

Battery power

The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.

The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.

Ram air turbine (RAT) generator

When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.

Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.

External power

Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.

The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.

The aft external power is only used when the ground power is required for engine start.

Circuit breakers

Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.

Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.

Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.

A normal flight

While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.

On the ground

When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.

Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.

APU start

As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.

The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.

If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.

Engine start

Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is  below 5°C.

On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.

Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.

After start

Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.

As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.

By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.

In-flight

Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.

Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.

Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.

Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.

Shutdown

With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.

However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.

Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.

Bottom line

Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.

The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.

The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.

Alliant Energy Net-Zero Carbon Plan outlines carbon-neutral electricity by 2050, coal retirements by 2040, major solar and wind additions, gas transition, battery storage, hydrogen, and carbon credits to reduce emissions and lower customer costs.

Key Points

Alliant Energy's strategy to reach carbon-neutral power by 2050 via coal phaseout, renewables, storage, and offsets.

✅ Targets net-zero electricity by 2050

✅ Retires all coal by 2040; expands solar and wind

✅ Uses storage, hydrogen, and offsets to bridge gaps

Alliant Energy has joined a small but growing group of utilities aiming for carbon-neutral electricity by 2050.

In a report released Wednesday, the Madison-based company announced a goal of “net-zero carbon dioxide emissions” from its electricity generation along with plans to eliminate all coal-powered generation by 2040, a decade earlier than the company’s previous target.

Alliant, which is pursuing plans that would make it the largest solar energy generator in Wisconsin, said it is on track to cut its 2005 carbon emissions in half by 2030.

Both goals are in line with targets an international group of scientists warn is necessary to avoid the most catastrophic impacts of climate change. But reducing greenhouse gasses was not the primary motivation, said executive vice president and general counsel Jim Gallegos.

“The primary driver is focused on our customers and communities and setting them up … to be competitive,” Gallegos said. “We do think renewables are going to do it better than fossil fuels.”

Alliant has told regulators it can save customers up to $6.5 billion over the next 35 years by adding more than 1,600 megawatts of renewable generation, closing one of its two remaining Wisconsin coal plants and taking other undisclosed actions.

In a statement, Alliant chairman and CEO John Larsen said the goal is part of broader corporate and social responsibility efforts “guided by our strategy and designed to deliver on our purpose — to serve customers and build stronger communities.”

Coal out; gas remains
The goal applies only to Alliant’s electricity generation — the company has no plans to stop distributing natural gas for heating — and is “net-zero,” meaning the company could use some form of carbon capture or purchase carbon credits to offset continuing emissions.

The plan relies heavily on renewable generation — seen in regions embracing clean power across North America — including the addition of up to 1,000 megawatts of new Wisconsin solar plants by the end of 2023 and 1,000 megawatts of Iowa wind generation added over the past four years — as well as natural gas generators to replace its aging coal fleet.

But Jeff Hanson, Alliant’s director of sustainability, said eliminating or offsetting all carbon emissions will require new tools, such as battery storage or possibly carbon-free fuels such as hydrogen, and awareness of the Three Mile Island debate over the role of nuclear power in the mix.

“Getting to the 2040 goals, that’s all based on the technologies of today,” Hanson said. “Can we get to net zero today? The challenge would be a pretty high bar to clear.”

Gallegos said the plan does not call for the construction of more large-scale natural gas generators like the recently completed $700 million West Riverside Energy Center in Beloit, though natural gas will remain a key piece of Alliant’s generation portfolio.

Alliant announced plans in May to close its 400-megawatt Edgewater plant in Sheboygan by the end of 2022, echoing how Alberta is retiring coal by 2023 as markets shift, but has not provided a date for the shutdown of the jointly owned 1,100-megawatt Columbia Energy Center near Portage, which received about $1 billion worth of pollution-control upgrades in the past decade.

Alliant’s Iowa subsidiary plans to convert its 52-year-old, 200-megawatt Burlington plant to natural gas by the end of next year and a pair of small coal-fired generators in Linn County by 2025. That leaves the 250-megawatt plant in Lansing, which is now 43 years old, and the 734-megawatt Ottumwa plant as the remaining coal-fired generators, even as others keep a U.S. coal plant running indefinitely elsewhere.

Earlier this year, the utility asked regulators to approve a roughly $900 million investment in six solar farms across the state with a total capacity of 675 megawatts, similar to plans in Ontario to seek new wind and solar to address supply needs. The company plans to apply next year for permission to add up to 325 additional megawatts.

Alliant said the carbon-neutral plan, which entails closing Edgewater along with other undisclosed actions, would save customers between $2 billion and $6.5 billion through 2055 compared to the status quo.

Tom Content, executive director of the Citizens Utility Board, said the consumer advocacy group wants to ensure that ratepayers aren’t forced to continue paying for coal plants that are no longer needed while also paying for new energy sources and would like to see a bigger role for energy efficiency and more transparency about the utilities’ pathways to decarbonization.

‘They could do better’
Environmental groups said the announcement is a step in the right direction, though they say utilities need to do even more to protect the environment and consumers.

Amid competition from cheaper natural gas and renewable energy and pressure from environmentally conscious investors, U.S. utilities have been closing coal plants at a record pace in recent years, as industry CEOs say a coal comeback is unlikely in the U.S., a trend that is expected to continue through the next decade.

“This is not industry leadership when we’re talking about emission reductions,” said Elizabeth Katt Reinders, regional campaign director for the Sierra Club, which has called on Alliant to retire the Columbia plant by 2026.

Closing Edgewater and Columbia would get Alliant nearly halfway to its emissions goals while saving customers more than $250 million over the next decade, according to a Sierra Club study released earlier this year.

“Retiring Edgewater was a really good decision. Investing in 1,000 megawatts of new solar is game-changing for Wisconsin,” Katt Reinders said. “In the same breath we can say this emissions reduction goal is unambitious. Our analysis has shown they can do far more far sooner.”

Scott Blankman, a former Alliant executive who now works as director of energy and air programs for Clean Wisconsin, said Alliant should not run the Columbia plant for another 20 years.

“If they’re saying they’re looking to get out of coal by 2040 in Wisconsin I’d be very disappointed,” Blankman said. “I do think they could do better.”

Alliant is the 15th U.S. investor-owned utility to set a net-zero target, according to the Natural Resources Defense Council, joining Madison Gas and Electric, which announced a similar goal last year. Minnesota-based Xcel Energy, which serves customers in western Wisconsin, was the first large investor-owned utility to set such a target, as state utilities report declining returns in coal operations.

U.S. Offshore Wind Capacity is set to exceed 1 GW by 2024, driven by BOEM approvals, federal leases, and resilient supply chains, with eastern states scaling renewable energy, turbines, and content despite COVID-19 disruptions.

Key Points

Projected gigawatt-scale offshore wind growth enabled by BOEM approvals, federal leases, and East Coast state demand.

✅ 17+ GW leased; only 1,870 MW in announced first phases.

✅ BOEM approvals are critical to reach >1 GW by 2024.

✅ Local supply chains mitigate COVID-19 impacts and lower costs.

Offshore wind in the U.S. will exceed 1 GW of capacity by 2024 and add more than 1 GW annually by 2027, a trajectory consistent with U.S. offshore wind power trends, according to a report released last week by Navigant Research.

The report calculated over 17 GW of offshore state and federal leases for wind production, reflecting forecasts that $1 trillion offshore wind market growth is possible. However, the owners of those leases have only announced first phase plans for 1,870 MW of capacity, leaving much of the projects in early stages with significant room to grow, according to senior research analyst Jesse Broehl.

The Business Network for Offshore Wind (BNOW) believes it is possible to hit 1 GW by 2023-24, according to CEO Liz Burdock. While the economy has taken a hit from the coronavirus pandemic, she said the offshore wind industry can continue growing as "the supply chain from Asia and Europe regains speed this summer, and the administration starts clearing" plans of construction.

BNOW is concerned with the economic hardship imposed on secondary and tertiary U.S. suppliers due to the global spread of COVID-19.

Offshore wind has been touted by many eastern states and governors as an opportunity to create jobs, with U.S. wind employment expected to expand, according to industry forecasts. Analysts see the growing momentum of projects as a way to further lower costs by creating a local supply chain, which could be jeopardized by a long-term shutdown and recession.

"The federal government must act now — today, not in December — and approve project construction and operation plans," a recent BNOW report said. Approving any of the seven projects before BOEM, which has recently received new lease requests, currently would allow small businesses to get to work "following the containment of the coronavirus," but approval of the projects next year "may be too late to keep them solvent."

The prospects for maintaining momentum in the industry falls largely to the Department of the Interior's Bureau of Ocean Energy Management (BOEM). The industry cannot hit the 1 GW milestone without project approvals by BOEM, which is revising processes to analyze federal permit applications in the context of "greater build out of offshore wind capacity," according to its website.

"It is heavily dependent on the project approval success," Burdock told Utility Dive.

Currently, seven projects are awaiting determinations from BOEM on their construction operation plans in Massachusetts, New York, where a major offshore wind farm was recently approved, New Jersey and Maryland, with more to be added soon, a BNOW spokesperson told Utility Dive.

To date, only one project has received BOEM approval for development in federal waters, a 12 MW pilot by Dominion Energy and Ørsted in Virginia. The two-turbine project is a stepping stone to a commercial-scale 2.6 GW project the companies say could begin installation as soon as 2024, and gave the developers experience with the permitting process.

In the U.S., developers have the capacity to develop 16.9 GW of offshore wind in federal U.S. lease areas, even as wind power's share of the electricity mix surges nationwide, Broehl told Utility Dive, but much of that is in early stages. The Navigant report did not address any impacts of coronavirus on offshore wind, he said.

Although Massachusetts has legislation in place to require utilities to purchase 1.6 GW of wind power by 2026, and several other projects are in early development stages, Navigant expects the first large offshore wind projects in the U.S. (exceeding 200 MW) will come online in 2022 or later, and the first projects with 400 MW or more capacity are likely to be built by 2024-2025, and lessons from the U.K.'s experience could help accelerate timelines. The U.S. would add about 1.2 GW in 2027, Broehl said.

The federal leasing activities along with the involvement from Eastern states and utilities "virtually guarantees that a large offshore wind market is going to take off in the U.S.," Broehl said.

bGen Thermal Energy Storage stores high-temperature heat in crushed rocks, enabling on-demand steam, hot water, or hot air; integrates renewables, shifts load with off-peak electricity, and decarbonizes campus heating at SUNY Purchase with NYPA.

Key Points

A rock-based TES system storing heat to deliver steam, hot water, or hot air using renewables or off-peak power.

✅ Uses crushed rocks to store high-temperature heat

✅ Cuts about 550 metric tons CO2 annually at SUNY Purchase

✅ Integrates renewables and off-peak electricity with NYPA

Brenmiller Energy Ltd. (NASDAQ: BNRG), in collaboration with the New York Power Authority (NYPA), a utility pursuing grid software modernization to improve reliability, has successfully deployed its first bGen™ thermal energy storage (TES) system in the United States at the State University of New York (SUNY) Purchase College. This milestone project, valued at $2.5 million, underscores the growing role of TES in advancing sustainable energy solutions.

Innovative TES Technology

The bGen™ system utilizes crushed rocks to store high-temperature heat, which can be harnessed to generate steam, hot air, or hot water on demand. This approach allows for the efficient use of excess renewable energy or off-peak electricity, and parallels microreactor storage advances that broaden thermal options, providing a reliable and cost-effective means of meeting heating needs. At SUNY Purchase College, the bGen™ system is designed to supply nearly 100% of the heating requirements for the Physical Education Building.

Environmental Impact

The implementation of the bGen™ system is expected to eliminate approximately 550 metric tons of greenhouse gas emissions annually. This reduction aligns with New York State's ambitious climate goals, including a 40% reduction in greenhouse gas emissions by 2030, even as transmission constraints can limit cross-border imports. The project also demonstrates the potential of TES to support the state's transition to a cleaner and more resilient energy system.

Collaborative Effort

The successful deployment of the bGen™ system at SUNY Purchase College is the result of a collaborative effort between Brenmiller Energy and NYPA. The project was partially funded by a grant from the Israel-U.S. Binational Industrial Research and Development (BIRD) Foundation. This partnership highlights the importance of international cooperation in advancing innovative energy technologies, as seen in OPG-TVA nuclear collaboration efforts across North America.

Future Prospects

The successful installation and operation of the bGen™ system at SUNY Purchase College serve as a model for broader adoption of TES technology in institutional settings, as OPG's SMR commitment signals parallel low-carbon investment across the region. Brenmiller Energy and NYPA plan to share the project's findings through a webinar hosted by the Renewable Thermal Collaborative on May 19, 2025. This initiative aims to promote the scalability and replicability of TES solutions across New York State and beyond.

As the demand for sustainable energy solutions continues to grow, the successful deployment of the bGen™ system at SUNY Purchase College marks a significant step forward in the integration of TES technology into the U.S. energy landscape, while projects like Pickering B refurbishment underscore parallel clean power investments. The project not only demonstrates the feasibility of TES but also sets a precedent for future initiatives aimed at reducing carbon emissions and enhancing energy efficiency.

Brenmiller Energy's commitment to innovation and sustainability positions the company as a key player in the evolving energy sector. With continued support from partners like NYPA and the BIRD Foundation, and as jurisdictions advance first SMR deployments in North America, Brenmiller Energy is poised to expand the reach of its TES solutions, contributing to a more sustainable and resilient energy future.

Germany Coal Phase-Out 2038 advances the energy transition, curbing lignite emissions while scaling renewable energy, carbon pricing, and hydrogen storage amid a nuclear phase-out and regional just-transition funding for miners and communities.

Key Points

Germany's plan to end coal by 2038, fund regional transition, and scale renewable energy while exiting nuclear.

✅ Closes last coal plant by 2038; reviews may accelerate.

✅ 40b euros aid for lignite regions and workforce.

✅ Emphasizes renewables, hydrogen, carbon pricing reforms.

German lawmakers have finalized the country's long-awaited phase-out of coal as an energy source, backing a plan that environmental groups say isn't ambitious enough and free marketeers criticize as a waste of taxpayers' money.

Bills approved by both houses of parliament Friday envision shutting down the last coal-fired power plant by 2038 and spending some 40 billion euros ($45 billion) to help affected regions cope with the transition, which has been complicated by grid expansion woes in recent years.

The plan is part of Germany's `energy transition' - an effort to wean Europe's biggest economy off planet-warming fossil fuels and generate all of the country's considerable energy needs from renewable sources. Achieving that goal is made harder than in comparable countries such as France and Britain because of Germany's existing commitment to also phase out nuclear power entirely by the end of 2022.

"The days of coal are numbered in Germany," Environment Minister Svenja Schulze said. "Germany is the first industrialized country that leaves behind both nuclear energy and coal."

Greenpeace and other environmental groups have staged vocal protests against the plan, including by dropping a banner down the front of the Reichstag building Friday. They argue that the government's road map won't reduce Germany's greenhouse gas emissions fast enough to meet the targets set out in the Paris climate accord.

"Germany, the country that burns the greatest amount of lignite coal worldwide, will burden the next generation with 18 more years of carbon dioxide," Greenpeace Germany's executive director Martin Kaiser told The Associated Press.

Kaiser, who was part of a government-appointed expert commission, accused Chancellor Angela Merkel of making a "historic mistake," saying an end date for coal of 2030 would have sent a strong signal for European and global climate policy. Merkel has said she wants Europe to be the first continent to end its greenhouse gas emissions, by 2050, even as some in Berlin debate a possible nuclear U-turn to reach that goal faster.

Germany closed its last black coal mine in 2018, but it continues to import the fuel and extract its own reserves of lignite, a brownish coal that is abundant in the west and east of the country, and generates about a third of its electricity from coal in recent years. Officials warn that the loss of mining jobs could hurt those economically fragile regions, though efforts are already under way to turn the vast lignite mines into nature reserves and lakeside resorts.

Schulze, the environment minister, said there would be regular government reviews to examine whether the end date for coal can be brought forward, even as Berlin temporarily extended nuclear operations during the energy crisis. She noted that by the end of 2022, eight of the country's most polluting coal-fired plants will have already been closed.

Environmentalists have also criticized the large sums being offered to coal companies to shut down their plants, a complaint shared by libertarians such as Germany's opposition Free Democratic Party.

Katja Suding, a leading FDP lawmaker, said the government should have opted to expand existing emissions trading systems that put a price on carbon, thereby encouraging operators to shut down unprofitable coal plants.

Katja Suding, a leading FDP lawmaker, said the government should have opted to expand existing emissions trading systems, rather than banking on a nuclear option, that put a price on carbon, thereby encouraging operators to shut down unprofitable coal plants.

"You just have to make it so expensive that it's not profitable anymore to turn coal into electricity," she said.

This week, utility companies in Spain shut down seven of the country's 15 coal-fired power plants, saying they couldn't be operated at profit without government subsidies.

But the head of Germany's main miners' union, Michael Vassiliadis, welcomed the decision, calling it a "historic milestone." He urged the government to focus next on an expansion of renewable energy generation and the use of hydrogen as a clean alternative for storing and transporting energy in the future, amid arguments that nuclear won't fix the gas crunch in the near term.

Power plant staff sequestration isolates essential operators on-site at plants and control centers, safeguarding critical infrastructure and grid reliability during the COVID-19 pandemic under DHS CISA guidance, with social distancing, offset shifts, and stockpiled supplies.

Key Points

A protocol isolating essential grid workers on-site to maintain operations at plants and control centers.

✅ Ensures grid reliability and continuity of critical infrastructure

✅ Implements social distancing, offset shifts, and isolation protocols

✅ Stockpiles food, beds, PPE, and sanitation for essential crews

The U.S. electric industry may ask essential staff to live on site at power plants and control centers to keep operations running if the coronavirus outbreak worsens, after a U.S. grid warning from the overseer, and has been stockpiling beds, blankets, and food for them, according to industry trade groups and electric cooperatives.

The contingency plans, if enacted, would mark an unprecedented step by power providers to keep their highly-skilled workers healthy as both private industry and governments scramble to minimize the impact of the global pandemic that has infected more than 227,000 people worldwide, with some utilities such as BC Hydro at Site C reporting COVID-19 updates as the situation evolves.

“The focus needs to be on things that keep the lights on and the gas flowing,” said Scott Aaronson, vice president of security and preparedness at the Edison Electric Institute (EEI), the nation’s biggest power industry association. He said that some “companies are already either sequestering a healthy group of their essential employees or are considering doing that and are identifying appropriate protocols to do that.”

Maria Korsnick, president of the Nuclear Energy Institute, said that some of the nation’s nearly 60 nuclear power plants are also “considering measures to isolate a core group to run the plant, stockpiling ready-to-eat meals and disposable tableware, laundry supplies and personal care items.”

Neither group identified specific companies, though nuclear worker concerns have been raised in some cases.

Electric power plants, oil and gas infrastructure and nuclear reactors are considered “critical infrastructure” by the federal government, and utilities continue to emphasize safety near downed lines even during emergencies. The U.S. Department of Homeland Security is charged with coordinating plans to keep them operational during an emergency.

A DHS spokesperson said that its Cybersecurity and Infrastructure Security Agency had issued guidance to local governments and businesses on Thursday asking them to implement policies to protect their critical staff from the virus, even as an EPA telework policy emerged during the pandemic.

“When continuous remote work is not possible, businesses should enlist strategies to reduce the likelihood of spreading the disease,” the guidance stated. “This includes, but is not necessarily limited to, separating staff by off-setting shift hours or days and/or social distancing.”

Public health officials have urged the public to practice social distancing as a preventative measure to slow the spread of the virus, and as more people work from home, rising residential electricity use is being observed alongside daily routines. If workers who are deemed essential still leave, go to work and return to their homes, it puts the people they live with at risk of exposure. 

California has imposed a statewide shutdown, asking all citizens who do not work in those critical infrastructure industries not to leave their homes, a shift that may raise household electricity bills for consumers. Similar actions have been put in place in cities across America.
