About Grid Data
What is an ISO/RTO?

What does LMP mean?
- Locational Marginal Price (LMP) is the cost of supplying the next megawatt of electricity at a specific location on the grid. It includes energy cost, transmission congestion, and losses. LMPs are the basis for wholesale electricity pricing.
How often is grid data updated?
- Grid data updates every 5 minutes during operating hours. This includes current load, generation mix, and real-time prices. Some data points may have slight delays depending on the ISO's publication schedule.
