Maximizing Solar Savings with National Grid MA
Time-of-Use Rate Optimization
National Grid MA uses time-of-use rates with peak pricing at $0.35/kWh and off-peak at $0.14/kWh. Solar panels produce the most energy during peak afternoon hours when rates are highest, maximizing your bill savings. Adding battery storage lets you store excess solar energy and use it during expensive peak periods.
Export Compensation
When your solar system produces more electricity than you use, the excess is exported to the grid. National Grid MA compensates you at $0.12/kWh for exported energy under their retail policy.
Battery Storage Benefits
National Grid MA offers battery storage incentives. A home battery system can store excess solar energy for use during peak rate periods or grid outages, improving your return on investment and energy independence.
