Connecticut Renewable Energy

Almost half of the electricity produced in Connecticut comes from the Millstone Nuclear Power Plant. This plant has 0 carbon emissions, and produces enough electricity to power 2 million homes. Natural gas accounts for most of the rest of Connecticut's electricity generation. However, Connecticut also produces small amounts of electricity from biomass, solar, hydroelectric, and coal-fired power plants.

Connecticut has an ambitious Renewable Portfolio Standard, which requires all electric suppliers in-state to sell a minimum percentage of renewable energy. The Standard has been updated several times, but the most recent version requires electric suppliers to use at least 23% renewable sources by 2020. Most of this renewable energy is purchased from other states because less than 4% of the electricity produced in Connecticut comes from renewable sources.

Connecticut Electricity Prices

Connecticut has a deregulated electricity market, where customers can choose their electricity supplier and often access lower electricity prices. According to the U.S. Energy Information Administration, the average retail price of electricity for Connecticut residents in December 2016 was 19.02¢ per kWh, which is 6.81¢ above the average U.S. residential electricity price of 12.21¢ per kWh.

Connecticut Electricity Rates

Residential electricity prices are on the rise in Connecticut. According to the U.S. Energy Information Administration, residential electricity prices in Connecticut have risen more than 10% over the past 5 years. This trend has led to higher electricity bills for Connecticut residents, motivating many to switch to renewable energy (i.e. go solar) to save money.

From 2005-2015, natural gas went from about 26% to 46% of Connecticut's total electricity production. Over the same period, electricity production from coal fell almost 85%.


Connecticut Energy Sector Employment

According to the Department of Energy, the Electric Power Generation segment employs 5,205 workers in Connecticut. More than half of these jobs are related to solar energy, and natural gas creates the second-most jobs in Connecticut. The most common solar jobs in Connecticut are installers, manufacturers, salespeople, and project managers. Some of the biggest Connecticut renewable energy companies are SolarCity, Greenskies, and OnForce Solar. 

Fun fact: more Americans are employed by renewable energy than coal, oil, and gas combined, despite wind and solar energy only making up 5% of the total U.S. energy mix. According to a study from the University of California, Berkeley, solar energy creates over 7 times more jobs than coal or oil per MWh produced. The employment estimates for wind power differ from source to source, but most agree that it also produces more jobs than fossil fuels.



Connecticut Utility Companies

Some of the largest utility companies in Connecticut are Eversource Energy, The United Illuminating Company (UI), and Connecticut Municipal Electric Energy Cooperative (CMEEC). Previously in Connecticut, one utility company controlled the entire flow of electricity, from production to distribution. However, the Connecticut energy market has since been “deregulated,” meaning that some elements of the service, such as electricity prices, can be set by other companies. This gives Connecticut businesses and homeowners the power to choose their electricity supplier.

Your local utility is still responsible for distributing electricity to every home in your area. In return, they send you a monthly bill, which you must pay to keep the electricity flowing. By default, they also produce or purchase your electricity. However, Connecticut’s deregulated energy market allows you to switch electricity suppliers to take advantage of lower electricity prices.
