To: Members of the House Science, Technology and Energy Committee, As currently written, the bill prohibits batteries in conjunction with net metering from ever being charged from the grid and conflicts with beneficial utility programs like Liberty’s battery pilot. An amendment to this bill is needed to address this issue. This amendment should: -Authorize the PUC to make exceptions to the general prohibition from grid charging -Allow utility-managed programs to charge customer storage devices before and after dispatch to shave system peaks -Ensure the bill does not unintentionally constrain customer resiliency benefits or market innovation I am a participant in the Liberty Battery pilot program and I recently installed solar in conjunction with this system. It is important that these systems are allowed to charge during times of low usage when the marginal price per MWh is lowest and discharge when prices are high and the grid is experiencing stress. During Winter we do not always have enough sunlight to fully charge our batteries from solar alone, in addition the grid is experiencing additional load due to electric heating, without the ability to charge from the grid all consumers will experience higher energy prices. For context we have over 23kW DC of solar (~19 kW AC), our battery system has 27 kWh of storage. There have been several days this Winter with this amount of solar that we have only produced 1-5 kWh of energy. Please consider amending this bill to ensure we have the tools to lower energy prices. Thank you for your consideration. Sincerely, Douglas Plumley Enfield, NH
