In light of the recent midterm elections, it seems like a good time to look at what makes good energy policy and what we might expect as a result of voter choices going forward. Policy plays an important role in the success of clean energy. As more states set targets for a future powered by renewables, there’s some trial and error in how to integrate new types of shared power to the existing grid, as well as how to support their growth and ensure ratepayers see the benefit of cleaner, less expensive energy. Community solar, when it’s supported by a state’s policies, is a very accessible and relatively inexpensive solution to these challenges.
Twenty nine states have a mandatory amount of clean energy utilities have to use, called a “Renewable Portfolio Standard (RPS)” while eight more have a voluntary clean energy target. These regulations have different ambition levels and methods of reaching their goals. Of these, only nineteen states have a shared renewables program. Shared renewables are those, like community solar, which allow everyone to participate in the benefits of clean power. Shared renewables programs allow new power sources like community solar to scale up. To compare how different states stacked up, the Interstate Renewable Energy Council (IREC) made a scorecard for states with established community solar programs. They evaluation criteria included such things as if the program is accessible to underserved and low income communities, if all residents are eligible to use the program, if it promotes subscription portability and transferability (being able to “take it with you” or give it to the next resident if you move) and how much benefit residents can get from joining a solar farm.
Massachusetts has one of the strongest programs in place to allow community solar to grow. It allows offset of both distribution and supply charges, targets benefits to low and moderate income customers, and has recently changed its program to remove barriers between utility load zones. This makes farms more accessible and beneficial to more residents, and it makes subscriptions much more portable.
At the polls this week, there was more good news for the future of clean energy. With a shift in congress, Democratic leadership has promised to “resurrect the defunct select committee on climate change.” Nevada also voted for a measure to use 50% renewable energy by 2030, and has seen increasing investment in clean energy recently.
Overall, states, rather than the federal government, continue to lead the charge against climate change. Experimenting with different programs to find the best practices paves the way for other states to follow suit. And as states with strong renewable energy programs reap rewards such as economic growth, financial savings, and environmental benefits, hopefully more policymakers and voters will come around.
