LCG, February 2, 2026--Ontario Power Generation (OPG) announced today that construction on the four-unit Darlington Refurbishment project is now complete. Station staff are completing final testing, and the last unit is expected to return to service in the coming weeks. OPG stated that the overall project is currently four months ahead of schedule and $150 million under budget.

Peak Energy Announces First Grid-Scale, Sodium-Ion Battery Energy Storage System in the U.S.
LCG, July 30, 2025--Peak Energy today announced the launch and shipment of its sodium-ion battery energy storage system (BESS) that includes a patent-pending passive cooling design that should significantly reduce lifetime energy costs. Peak Energy's system is to be deployed this summer in a shared pilot project with nine utility and independent power producer (IPP) customers.
Peak Energy's announcement states that its system is the first ever fully passive megawatt-hour scale BESS. Moreover, it will deploy the largest sodium-ion phosphate pyrophosphate (NFPP) battery system in the world and the first grid-scale, sodium-ion storage solution ever connected to the nation's electric grid. The design eliminates all moving parts, including active cooling and ventilation components, and completely eliminates the most common failure modes in typical battery storage systems, which improves reliability and reduces operating and maintenance costs. Furthermore, Peak Energy states that its design removes the root cause of 89 percent of reported battery storage system fires in the United States, as documented by the Electric Power Research Institute (EPRI).
Peak Energy states that it has conducted extensive performance testing of its system, and results indicate: up to 90 percent reduction in auxiliary power use; approximately a 20 percent lifetime cost savings versus Lithium Iron Phosphate (LFP) in an average deployment; and a 33 percent reduction in battery degradation over a 20-year project lifespan.
"This isn't just another product launch – it's a breakthrough in energy storage," said Peak Energy's VP of Engineering. "We've taken a very stable chemistry and invested its benefits back into our passive cooling architecture. The system is dead-simple with no moving parts, no planned maintenance and negligible aux loads. It's the lowest total-cost grid storage technology to be deployed anywhere in the world. I'm incredibly proud of the creativity and grit our team has shown in bringing our vision to life."
Peak Energy's announcement also highlights that the use of sodium-ion presents the United States' best opportunity to lead in battery chemistries given that the United States holds the world's largest reserves of soda ash, the mineral precursor to sodium-ion, and the full raw material supply chain for sodium-ion can be sourced domestically or from allied nations.
"We see energy storage not only as an economic imperative, but also as a national security priority. Time is of the essence if the U.S. wants to take ownership and maintain control of its energy future," said Peak Energy's CEO and Co-Founder. "We are committed to onshoring the manufacturing of this critical industry, and this launch proves our ability to execute quickly on our vision to establish the U.S. as a global leader in battery manufacturing."
Peak Energy states that its pilot project marks a significant first step in commercializing sodium-ion battery storage in the United States and that it will unlock nearly 1 GWh of future commercial contracts currently under negotiation. Following the pilot, Peak Energy will deploy several hundred megawatt hours of commercial-scale storage products to serve multiple IPP and hyperscaler partners over the next two years.
