A Bowmanville cement plant is taking a 50 MWh battery with nothing due up front - the megawatts are blank, one trade page hopes for May 2028, and the box charges from the grid
On 27 October 2026 Rodan Energy and St. Marys Cement said Rodan will develop, own and operate a 50 MWh battery behind the meter at the Bowmanville, Ontario plant. St. Marys pays nothing up front. The release does not print megawatts, a dollar figure, a savings split or a switch-on date. CemNet, on 29 October, says those four lines were not disclosed. Energy Tech, on 28 October, writes that Rodan hopes to switch on by May 2028. No solar is named. The battery charges from the grid.
