Net Metering

There are 41 companies in Connecticut providing electricity. Of those 41,13 of them offer some type of net metering option for their customers, making solar panels and alternative electric sources more economically viable. Regulations put in place at the state level are some of the best for consumers interested in installing solar or other alternative electricity generation sources.

Energy Loss

Connecticut has 12 providers who are reporting energy loss during transmission activities. The average energy loss amount for these 12 companies is 1.70%. For comparison, the countrywide average electricity loss is 2.72%. Connecticut has a rank of 48th worst in the country for energy loss.

Solar Taxes And Rebates

When it comes to stimulating solar panel installs at private residences, one of the best uses of government resources is tax breaks and rebates for solar installs. Connecticut currently offers no state tax credit to consumers who install solar at their place of residence. Residents in the state enjoy rebates for solar panel installs of over $500. This is the highest amount we’ve seen in the US. Fortunately, Connecticut offers a 100% tax exemption to residents who wish to install solar panels. Fortunately, residents in the state have a 100% sales tax exemption for the install of private solar panels. Can’t beat that!

State Level Initiatives

Customers who are seeking electricity options that generated by renewable sources will benefit from statewide initiatives that encourage green energy usage. Many states require green fuel types to be a portion of the fuel used for electricity generation. These stipulations are referred to as Renewable Portfolio Standards (RPS). Electric providers in Connecticut are required to produce at least 25% of their output using renewable fuel types. Also, low income solar programs are another way a state can encourage renewable fuel types and the state of Connecticut is home to one such program.
