An unprecedented backlog of clean energy projects is in line to join PJM Interconnection, an electricity market serving one in five Americans. ---PJM Interconnection, the largest wholesale electricity market in the U.S., is on the verge of going solar in a big way. The market, which encompasses 13 states from the mid-Atlantic shore, through fossil fuel-rich Pennsylvania and Ohio and as far West as Illinois, has a massive backlog of clean energy projects of all types that are waiting to be built, with solar foremost among them. In fact, the amount of clean energy in line to join PJM totals more than all of the generation capacity that exists in the market today.Mike Borgatti, Vice President of RTO Services and Regulatory Affairs at Gabel Associates, discusses the unprecedented number of new clean energy projects that are lined up in PJM’s interconnection queue, and the policy and economic factors that are driving the shift to solar, wind and storage. He also takes a look at the decline in the number of natural gas projects waiting to enter the market, and what all of these developments may mean for the future power mix.Mike Borgatti is Vice President of RTO Services and Regulatory Affairs at Gabel Associates, an energy, environmental and public utility consulting company.Related Content The Opportunities and Limitations of Seasonal Energy Storage. https://kleinmanenergy.upenn.edu/research/publications/the-opportunities-and-limitations-of-seasonal-energy-storage/ Electricity Storage and Renewables: How Investments Change as Technology Improves. https://kleinmanenergy.upenn.edu/research/publications/electricity-storage-and-renewables-how-investments-change-as-technology-improves/As Climate Concerns Rise, What Role Will Natural Gas Play? https://kleinmanenergy.upenn.edu/podcast/as-climate-concerns-rise-what-role-will-natural-gas-play/
