Inside the largest power market in the US: How PJM is navigating the collision of data centres, decarbonization, and affordability.

When the workings of an electricity market come to the attention of the White House, it’s usually a sign that something’s wrong. Back in January, 13 state governors went to the White House to agree plans for PJM, the largest electricity market in the US. The market is scrambling to find more energy supply to keep up with the boom in data centers, while holding down ratepayers’ bills. Managing the PJM grid is one of the toughest jobs in the US power industry. And these days it is being carried out in the full glare of political and public scrutiny. If you want to understand the pressures bearing down on the US electricity, PJM is the place to look. It is the largest grid in the country, serving 67 million people across 13 states and the District of Columbia. And it is some of the world's most intense hotspots for new data center development, including the famous “data center alley” of northern Virginia, which takes roughly 90% of the country's internet traffic . When things get complicated for PJM, they get complicated for everyone. On this episode, host Ed Crooks is joined by Asim Haque, Senior Vice President for Governmental and Member Services at PJM, and by regular guest Amy Myers Jaffe, Director of the Energy, Climate Justice and Sustainability Lab at New York University. Together, they unpack how PJM got itself noticed by the White House, and how its problems can be tackled. Asim explains the organization he works for. PJM is a nonprofit that operates the grid, runs the electricity market, and plans the transmission system. It is regulated by FERC, but also accountable to a thousand-plus members across 13 states, each with its own energy policies, its own governor, and its own politics. That structural complexity is central to why running PJM is so challenging. Those problems converged from two directions: decarbonization and data centers. The result has been soaring prices in the PJM capacity market. And when those prices were capped, the alarms about a future reliability crisis started flashing red. The White House responded by convening all 13 governors of the states covered by PJM, and produced a statement of principles for bringing new generation capacity into the market. As Asim explains, these principles lie behind the plan for a backstop reliability procurement, designed as a one-time mechanism to bring new electricity supply onto the system quickly. There is also an expectation that data centres will bring their own generation; and a "connect and manage" framework for those that don't. The key feature of that: data centers can have their supply curtailed before residential customers lose power. The White House and the governors agreed that the bill for grid and generation improvements to meet rising demand should be paid by the data centers. It sounds straightforward, but is it really? Asim explains his perspective. The episode also examines the deeper design questions about PJM’s capacity market: whether a three-year forward procurement window can send the right signals for the long-term investment the grid now needs. Amy brings the consumer and policy lens throughout. Are the complexities of cost allocation and market design inherent to the electricity system, or are they manufactured and even sometimes exaggerated? And can they sometimes militate against lower-cost solutions such as renewables and batteries? Asim ends by offering some advice for other grid operators. If you are not going to gate demand, you need a connect-and-manage approach; if you are not going to gate demand, it will get expensive; and if it is going to get expensive, you need to decide who pays.
