        Minnesota to Consider Using Energy Storage for Peaker Plants

        Gas peaker plants may be among the first casualties of a new Minnesota law requiring utilities to include energy storage as part of their long-range plans. The provision, part of an omnibus jobs and energy bill, "puts energy storage on a level playing field with natural gas plants and other resources," said Ellen Anderson, executive director of the University of Minnesota's Energy Transition Lab. "Utilities will have to acknowledge the capabilities storage can provide as an alternative to, say, a fossil fuel plant."

        Lithium Batteries: Far More Widely Recycled than Second-Hand Statistics Imply

        Lithium-ion batteries are far more widely recycled than many people think, while China and South Korea are already leaders of the emerging circular economy of lithium, a report commissioned by the Swedish Energy Agency has found. The report has been republished in English after a launch in Spring in Swedish. The author stated that many misconceptions and poor observations are made and repeated around lithium recycling and that more than 70% of lithium-ion batteries recycled today are processed in China and South Korea, with “high” recovery rates of materials.

        Power Plants Create Giant Water Battery

        California is a leader in renewable energy, and the state has pledged to use only clean sources for electricity, including wind and solar power, by 2045. One hurdle is energy storage, but an old solution involving water may help the state reach its goal of zero emissions. The solution is pumped storage, which uses water in reservoirs at different elevations to smooth the fluctuations of intermittent power from the wind and sun, and makes electricity available when it is needed.

        New York Regulators Assess Potential for Storage to Replace Peaking Units in the State

        New York's Department of Public Services on Monday issued two reports on energy storage development in the state — a unit-by-unit study of replacing or repowering peaking units in the state and a review of a DER Data Platform pilot.
        At least 275 MW of peaking units, or about 6% of the total rated capacity of New York's peaking fleet, were identified as potential candidates for replacement with six‐hour energy storage sized to the maximum 2013 output of each peaking unit, according to study. This number increases to over 500 MW when using eight‐hour duration storage.

        Utility-Scale Energy Storage Will Enable a Renewable Grid

        The way the world gets its electricity is undergoing a rapid transition, driven by both the increased urgency of decarbonizing energy systems and the plummeting costs of wind and solar technology. But the intermittent nature of those sources means that electric utilities need a way to keep energy in their back pocket for when the sun is not shining and the winds are calm. That need is increasing interest in energy-storage technology which is finally poised to be more than just a bit player in the grid.

        PNM Plans Early Retirement of Coal Plant with Massive Addition of Solar + Storage

        Public Service of New Mexico (PNM) filed a plan with regulators for how it plans to get to 100% emission-free power by 2040. The utility reviewed four scenarios, all of which involved the early retirement of the San Juan Coal Plant, to arrive at its recommended path forward. PMN recommends using the energy from a 280-MW gas-fired power plant, plus 350 MW of solar capacity, 130 MW of battery storage and 140 MW of wind power. The battery storage will represent 5 percent of the total capacity of the system, which is the highest percent penetration in the nation, according to PNM. PNM says its plan will save customers on average $7.11 per month in the first year.
