PJM drops Oklo advanced nuclear project from interconnection study cycle

This is a story about large-scale power grid planning, not something that touches homeowner energy upgrades directly, but it shows how big new demand for electricity is working through the system.

Nuclear technology company Oklo has filed a complaint with federal regulators after PJM Interconnection, the grid operator covering much of the mid-Atlantic and parts of the Midwest, pulled Oklo's 750-megawatt power project out of its review process for connecting new generation to the grid. The project, planned for Pike County, Ohio, mixes advanced nuclear power, natural gas, and fuel cells, and would supply electricity to Meta's data centers under a deal reached earlier this year. Oklo says PJM's move violates its own rules and will delay the project by at least 14 months, raising its costs, and it's asking regulators to force PJM to reinstate the project.

For homeowners, this doesn't change anything about rebates or home upgrades. But it's part of a bigger pattern: utilities and grid operators like PJM are managing a wave of new demand for electricity, largely driven by data centers, and disputes like this one show how contested and slow that process can be. As data centers compete for grid capacity, it can affect how much power is available and how electricity prices move in regions served by PJM, which spans parts of many states including Ohio, Pennsylvania, and Virginia.
