Net Metering Available

Get paid for the extra solar you produce

Net metering policies in Connecticut can help solar panel owners save money and reduce their carbon footprint. When your solar panels generate more electricity than you use, you can send the excess back to the grid and receive credit on your next bill. Just something to keep in mind when considering solar panels.

The Deregulation of Connecticut’s Power Grid

Connecticut adopted PA 98-28 in 1988, which deregulated its electric industry and allowed consumers to choose their electric suppliers.

This act required Connecticut Light & Power (CL&P), now Eversource, and United Illuminating (UI) to unbundle their services and sell off their generation assets so they were able to start purchasing power on the wholesale market alongside new competitive retail suppliers. It also required the Department of Public Utility Control (DPUC) to take the first steps to establish a competitive market.

According to a report released in 2011 by Connecticut government officials, 41.8% of all customers in Connecticut have chosen competitive suppliers, among the highest in the country.

Renewable Power in Connecticut

In addition to the deregulation, PA 98-28 required suppliers to obtain part of their power from renewable sources.

According to the U.S. Energy Information Administration (EIA), in 2017, almost half of Connecticut’s net electricity generation came from the state’s Millstone nuclear station. In that same year, about 4.7% of the state’s net electricity generation came from renewable energy resources.

Connecticut aims for a high Renewable Portfolio Standard that requires electric providers to sell a minimum percentage of renewable energy. While nuclear power remains a large source of electricity to the state, Connecticut aims to increase the adoption of solar, wind, and hydroelectric power to diversify its energy generation. In June of 2019, Connecticut lawmakers passed House Bill 7156 to procure up to 2 GW of offshore wind power.

A lot of WattBuy’s suppliers use renewable energy sources to generate their energy. You can check if any renewable energy sources are available in your area by inputting your zip code at the top of this page!
