Description: In December of 2025 a final switch was flipped and 160 megawatts of electricity started flowing onto Maryland’s grid from the biggest solar farm in the entire state, the Backbone power project in Garrett County. To give you a sense of how big 160 megawatts is, this project will produce more electricity than all the homes in Garrett County combined use in a year. When Backbone Power came online, it single handedly increased the total amount of solar power installed in Maryland by over 5%.The project would be newsworthy just because of its size, but on top of that it also happens to be located on an old coal mine and is now providing local and state tax revenue that was lost when that coal mine closed.This project is a great example of the tremendous benefits we get out of investing in the state’s Renewable Portfolio Standard in terms of jobs, tax revenue, and instate generation, but to me it also feels like a symbol of possibility, proof in miniature that transitioning to the clean economy is possible and beneficial. To talk all about this project, the Maryland energy policies that made it possible, and what lawmakers can do to make sure more projects like this one keep coming online, I am joined by Mike Resca, the executive Vice-President of CPV Renewables, the company that developed the backbone solar project.
