In Massachusetts, other energy companies that offer solar panel net metering include Eversource and Con Edison. Is National Grid’s net metering the best in Massachusetts, New York, and Rhode Island? Massachusetts There is no net metering cap for customers in National Grid’s Rhode Island service territory. The cap is set at 100 MW, so the 85% capacity marker is set at 85 MW. The Public Service Commission requires each utility in New York to report when they reach 85% of their recommended net metering capacity so subsequent action can be determined. It is set at 2% of incremental net revenue, which is equivalent to 100 MW. Now, the net metering cap is determined by calculating net metering’s impact on the utility’s net revenue.
In March 2017, New York State transitioned away from a “peak load” based cap. Most residential homes have a single-phase circuit – so, if your system is over 10 kW, there’s a good chance the net metering cap will apply. However, systems that have a nameplate rating less than 10 kW on a single-phase circuit or 25 kW on a three-phase circuit are exempt from the net metering cap. National Grid’s cap is 359.19 MW for private customers and 410.54 MW for public entities. As of April 2016, the net metering cap for Massachusetts limits net metering to 7% of a utility’s historical peak load for private customers and 8% for public entities.
The net metering cap of a utility represents how many solar (or other renewable energy) installations can participate in the net metering program. What is National Grid’s net metering cap? Massachusetts In addition, National Grid owns the revenue meter installed for net metering, and customers are responsible for associated taxes, meter maintenance, incremental readings, and billing costs to the utility on a monthly basis. Customers will still be responsible for paying any demand charges or customer charges associated with the account. Based on current residential rates (as of late 2020) this adds up to approximately 11 cents/kWh. The credits are worth the retail price of electricity in Rhode Island, calculated as the sum of Standard Offer Service, Distribution, Transmission, and Transition charges. The residential rate varies and can be viewed on National Grid's website. Like other net metering programs, National Grid’s program allows customers to financially balance out the amount of energy exported back to the grid with the energy imported from the grid over the course of the billing period. National Grid customers in Rhode Island are eligible to receive net metering credits when using a solar panel system. The residential rate varies by month and can be viewed on National Grid's website. When a customer exports more energy than they use in a given month, they receive credits on their bill that are calculated by multiplying Supply Costs, Delivery, Market Settlement, State Assessment, and System Benefit charges by the number of excess kWh. Residential net metering on solar panel systems up to 25 kW is available through National Grid in New York. Most residential systems are under 20 kW, so they fall under this category. The value of the credit depends on the size of the customer’s solar panel system, and can be viewed on National Grid's website.įor customers with solar panel systems under 1,000 kW, the net metering credit is determined by multiplying the number of kilowatt hours (kWh) exported back to the grid by the sum of Supply Costs, Distribution, Basic Service, Transmission, and Transition. When a customer exports or feeds more power back to the grid than they use, they qualify for net metering credits. What are National Grid’s rates and prices for net metering? Massachusetts
