Green Mountain Power is developing three projects to add 14.4 MW of solar and 6 MW of storage to its system.
When it comes to energy storage, “there’s a big range of potential futures out there,” one researcher said.
Liberty Utilities’ proposed program would include a “bring your own device” option for customers during its second phase.
The state awarded $20 million in grants with hopes of helping to increase state’s storage capacity by more than tenfold.
The test projects involve using cheap materials to store energy as heat and convert it to electricity when needed.
