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.

Canada Electricity Shortage threatens renewable energy transition as EV adoption and building decarbonization surge; Hydro-Quebec exports, wind power expansion, demand response, and smart grid resilience shape investment and capacity planning.

Key Points

A looming supply gap in central and eastern provinces driven by EVs, heating decarbonization, exports, and limited new hydro.

✅ Hydro-Quebec capacity pressured by exports and new loads

✅ Wind power prioritized; new mega-dams deemed unworkable

✅ Smart meters boost flexibility but raise cyber risk

Quebec and other provinces in central and eastern Canada are heading toward a significant shortage of electricity to respond to the various needs of a transition to renewable energy, and Ontario's energy storage push underscores how supply is tightening across the region.

This is according to Polytechnique Montréal’s Institut de l’énergie Trottier, which published a report titled A Strategic Perspective on Electricity in Central and Eastern Canada last week.

The white paper says that at the current rate, most provinces will be incapable of meeting the electricity needs created by the increase in the number of electric vehicles, including the federal 2035 EV sales mandate that will amplify demand, and the decarbonization of building heating by 2030. “The situation worsens if we consider carbon neutrality objectives of the federal government and some provinces for 2050,” the institute says.

The researchers called on public utilities to immediately review their investment plans for the coming years in light of examples such as B.C.'s power supply challenges that accompany rapid green ambitions.

In a news conference Wednesday, Premier François Legault said the province could indeed be short on electricity as debates over Quebec's EV push continue. “We’re open to exploiting green hydrogen, if the price is good and also based on the electrical capacity we have. Because currently, we predict that in the coming years we’re going to lack electricity, so we must be prudent.”

Quebec is in a better position than other provinces because it is the largest hydroelectricity producer in the country. But that energy source also attracts new clients that have contributed to increased demand over the coming years, including data centres, cryptocurrency miners and greenhouses.

Report co-author Normand Mousseau said that while Hydro-Québec largely has the capacity to meet demand from electric vehicles, even amid EV shortages and wait times for buyers, heating and manufacturers, export contracts to the United States “risk reducing its leeway.”

Hydro-Québec will therefore have to find new sources of electricity, and Mousseau said the answer isn’t new dams.

“The reservoirs give an immense flexibility to the network, but we don’t have the capacity today to flood territories like we have done in the past,” said Mousseau, the institute’s scientific director. “From an environmental viewpoint and a social accessibility one, it’s unworkable.”

The solution would be more wind turbines, he said, adding construction could happen at “very competitive rates” and if there’s a surplus, “we can sell it without issue because other provinces are in an even worse situation than ours,” a reality echoed by eco groups in Northern Ontario sustainability discussions focused on the grid’s future.

The researchers propose solutions based on six themes: regulations, pricing, demand management, data, support for implementation and resilience.

In the resilience category, the report notes that innovative technology like smart meters makes the network more flexible, with pilots such as EV-to-grid integration in Nova Scotia illustrating emerging options, but also increases the risk of cyberattacks. The more extreme weather caused by climate change also increases the risks of damage to infrastructure while at the same time increasing demand.

DOE Office of Fossil Energy safeguards energy security via the Strategic Petroleum Reserve, domestic critical minerals from coal byproducts, and carbon capture to curb CO2, strengthening resiliency amid shocks and supporting U.S. manufacturing and defense.

Key Points

A DOE program advancing energy security through SPR stewardship, critical minerals R&D, and carbon capture.

✅ Manages the Strategic Petroleum Reserve for emergency crude supply

✅ Develops domestic critical minerals from coal and mining byproducts

✅ Deploys carbon capture, utilization, and storage to cut CO2

The global economy has just experienced a period of unique transformation because of COVID-19. The fact that remains constant in this new economic landscape is that our society relies on energy; it’s an integral part of our day-to-day lives, even as U.S. energy use has evolved over time. According to the U.S. Energy Information Administration, approximately 80 percent of energy consumption in the United States comes from fossil fuels, so having access to a secure and reliable supply of those energy resources is more important than ever for national energy security considerations today. Below are three examples that highlight how our work at the U.S. Department of Energy’s Office of Fossil Energy (FE) helps ensure the Nation’s energy security and resiliency.

(1) Open crude oil reserves to respond to crises

FE has overall program responsibility for carrying out the mission of the Strategic Petroleum Reserve (SPR), the world’s largest supply of emergency crude oil. These federally-owned stocks are stored in massive underground salt caverns along the coastline of the Gulf of Mexico. The SPR is a powerful tool U.S. leaders use to respond to a wide range of crises, including energy crisis impacts on electricity and fuels, involving crude oil disruption or demand loss.  When the COVID-19 pandemic hit, the oil markets crashed and crude oil demand dropped drastically across the world. U.S. oil producers turned to the SPR to store their oil while broader energy dominance constraints were becoming evident in practice. This helped alleviate the pressure on producers to shut in oil production and proved to be a critical asset for American energy and national security.

(2) Use the Nation’s abundant coal reserves to produce valuable materials

Critical materials, including rare earth elements, are a group of chemical elements and materials with unique properties that support manufacturing of most modern technologies. They are essential components for critical defense and homeland security applications, green energy technologies, hybrid and electric vehicles, and high-value electronics. While these materials are not rare, they are hard to separate and expensive to extract. The United States relies heavily on imports from China. To reduce U.S. dependence on foreign sources, FE has a research and development program aimed at producing a domestic supply of critical materials from the Nation’s abundant coal resources and associated byproducts from legacy and current mining operations. Many of the technologies being developed can also be used to separate critical minerals from other mining materials and byproducts. Tapping into these resources has the potential to create new industries and revitalize coal communities and the workforce in coal-producing regions.

(3) Decrease carbon emissions for a cleaner energy future

FE is committed to balancing the Nation’s energy use with the need to protect the environment, and has a comprehensive portfolio of technological solutions that help keep carbon dioxide (CO2) emissions out of the atmosphere. For example, amid high natural gas prices that reinforce the case for clean electricity, the Department has been investing in carbon capture, utilization, and storage technologies for over a decade. These technologies capture CO2 emissions from various sources, including coal-fired power plants and manufacturing plants, before they enter the atmosphere. Several of these cutting-edge technologies have been deployed at major demonstration sites, supported by clean energy funding that aims to benefit millions. Three of these projects—Petra Nova, Archer Daniels Midland, and Air Products & Chemicals—have captured and injected over 10.8 million metric tons of CO2. The success of these projects is paving the way toward a cleaner and more sustainable American energy future.

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”

Brazil ICMS Tax Cap limits state VAT on fuels, natural gas, electricity, communications, and transit, promising short-term price relief amid inflation, with federal compensation to states and potential legal challenges affecting investments and ANP auctions.

Key Points

A policy capping state VAT at 17-18 percent on fuels, electricity, and services to temper prices and inflation.

✅ Caps VAT to 17-18% on fuels, power, telecom, transit

✅ Short-term relief; medium-long term impact uncertain

✅ Federal compensation; potential court challenges, investment risk

Brazil’s congress approved a bill that limits the ICMS tax rate that state governments can charge on fuels, natural gas, electricity, communications, and public transportation. 

Local lawyers told BNamericas that the measure may reduce fuel and power prices in the short term, similar to Brazil power sector relief loans seen during the pandemic, but it is unlikely to produce any major effects in the medium and long term. 

In most states the ceiling was set at 17% or 18% and the federal government will pay compensation to the states for lost tax revenue until December 31, via reduced payments on debts that states owe the federal government.

The bill will become law once signed by President Jair Bolsonaro, who pushed strongly for the proposal with an eye on his struggling reelection campaign for the October presidential election. Double-digit inflation has turned into a major election issue and fuel and electricity prices have been among the main inflation drivers, as seen in EU energy-driven inflation across the bloc this year. Congress’ approval of the bill is seen by analysts as political victory for the Brazilian leader.

How much difference will it make?

Marcus Francisco, tax specialist and partner at Villemor Amaral Advogados, said that in the formation of fuel and electricity prices there are other factors, including high natural gas prices, that drive increases.

“In the case of fuels, if the barrel of oil [price] increases, automatically the final price for the consumer will go up. For electricity, on the other hand, there are several subsidies and policy choices such as Florida rejecting federal solar incentives that are part of the price and that can increase the rate [paid],” he said. 

There is also a possibility that some states will take the issue to the supreme court since ICMS is a key source of revenue for them, Francisco added.

Tiago Severini, a partner at law firm Vieira Rezende, said the comparison between the revenue impact and the effective price reduction, based on the estimates made by the states and the federal government, seems disproportionate, and, as seen in Europe, rolling back European electricity prices is often tougher than it appears. 

“In other words, a large tax collection impact is generated, which is quite unequal among the different states, for a not so strong price reduction,” he said.

“Due to the lack of clarity regarding the precision of the calculations involved, it’s difficult even to assess the adequacy of the offsets the federal government has been considering, and international cases such as France's new electricity pricing scheme illustrate how complex it can be to align fiscal offsets with regulatory constraints, to cover the cost it would have with the compensation for the states” Severini added.

The compensation ideas that are known so far include hiking other taxes, such as the social contribution on net profits (CSLL) that is paid by oil and gas firms focused on exploration and production.

“This can generate severe adverse effects, such as legal disputes, reduced investments in the country, and reduced attractiveness of the new auctions by [sector regulator] ANP, and costly interventions like the Texas electricity market bailout after extreme weather events,” Severini said.
