Putting a battery with a wind farm in the US is more or less unheard of, because even battery backed wind is typically only able to bid for a fraction of its output in capacity and wholesale markets. So when Glidepath sent us a release about it this week, whereby it plans to buy up 149 MW of wind farms in North Texas and pair them with batteries, we took note. Glidepath’s idea seems to be putting the same capacity in MWh as the wind capacity itself has in peak capacity, in batteries – so 149 MWh of battery for 149 MW of turbines. That would likely give it 25% of that capacity for four hours (37 MW) to support…
