Updated Map on PJM Website Shows Price of Wholesale Electricity in Your Area

We’ve made it easier to see the wholesale price of electricity in your area with an improved Locational Marginal Pricing Map on pjm.com. The locational marginal price is the price of wholesale electricity for each location in the PJM footprint.

A legend in the bottom right corner of the map shows the color codes for the current wholesale price of electricity. You can zoom in on a specific location of the map for details.

Clicking on a specific area shows you two additional costs of electricity: marginal losses and congestion. Marginal losses the cost of the megawatts lost in moving electricity through transmission lines. Congestion prices are the higher cost of providing power from local generators when transmission lines can’t deliver any more lower-priced energy to an area.
