Benefiting from community solarIn a nutshell, community-owned solar gardens & farms let their participants partake in the financial and environmental benefits of solar power even without a roof. If you are a participant in a community solar project, you should expect to save money on your power bill. Exactly how these savings are delivered will vary by location and program, but as with rooftop solar, it is key that anyone considering buying electricity from a community solar garden shop around and be well-informed before making a decision.
Many States in the U.S. Advocate For Community Solar GardensMore and more community solar gardens are appearing in more and more states as policies come into place to support them. Currently, 9 states and Washington DC have all enacted policies governing and supporting shared solar projects, according to advocacy group www.SharedRenewables.org. In at least 10 other states (or parts of states) there are campaigns underway to have shared renewable project legislation brought in. As part of its SunShot initiative, the US Department of Energy (DOE) has also been looking to boost community solar for some years now, updating its definitive 2010 report on the topic, A Guide to Community Solar, in 2012. Further clearing the path, the National Renewable Energy Laboratory (NREL) recently introduced a Community Solar Scenario Tool (CSST) to help communities and developers alike assess the financial viability of potential community projects.
States leading the wayAt the moment, the number of programs available is still small but growing, especially in states with community solar policies. If you live in one of the states below, you can either keep an eye out for community solar projects developed by others – or even consider starting one of your own.Solar Gardens Institute and the rapidly expanding community solar project developer Clean Energy Collective, Colorado is home to more community solar farms than any other state, with at least 19 in operation at the time of writing. State policy makes it relatively easy for projects to be developed and for benefits to be paid out through utilities. It also encourages participants to be owners in projects, and as such, most Colorado programs are ownership-based.Virtual Net Metering (VNM) policy. The state is home to a number of ideal-driven, locally-initiated community solar gardens such as the Brewster Community Solar Garden and Harvard Solar Garden, but other players looking to sell community solar for profit are quickly entering the scene.Group Net Metering‘. Group Net Metering takes the ‘community’ aspect of community solar one step further than most other states, allowing any person in charge/owner of a renewable energy facility to determine how the renewable energy credits it produces are allotted, avoiding the need to have a utility administer the program or its payouts. Additionally, all Net Metering credits created through a solar system in the state (rooftop, community or otherwise) benefit from a ‘solar adder’ which increases their value above whatever their utility rate is.Group Net Metering legislation, offering benefits essentially the same as those in Vermont.Net Energy Billing‘) legislation; project participants must have a legally enforceable ownership stake in the projects that they receive benefits from, and at least 51% of owners need to be local. A project may have up to 10 owners and its electricity split between up to 10 meters. The state is currently piloting a program to incentivize energy generation from community projects.
