The electric grid operator for the region that includes Pennsylvania is preparing for a shift in electricity generation.
PJM Interconnection recently released a road map for the grid of the future.
Over the next 15 years, it expects to add 100,000 megawatts of renewable power from sources including onshore and offshore wind, solar, and battery storage. Right now there are about 15,000 MW of renewables on the PJM grid. It takes one megawatt to power about 200 homes.
PJM estimates it will cost $3 billion to bring on those resources. Some of those costs could be offset by federal infrastructure money. But some will ultimately filter down to consumers’ bills. However, some experts argue that the low cost of generating renewable energy and a more efficient grid will save money in the long term.
To prepare, PJM is looking to streamline the process for new sources to join the grid and studying how to expand transmission and maintain reliability.
Electric generators and municipalities within PJM recently voted to speed up and improve the process for getting new power on the grid. The plan is expected to go into effect later this year or in early 2023.
Under it, proposed projects would be addressed on a first-ready, first-served basis rather than first come, first served. PJM would also simplify its analysis of project costs.
The operator says the number of projects entering its New Services Queue has nearly tripled over the past four years, because of the rapid growth in renewables.
