About GridReason

What we do

GridReason Energy Analytics predicts regional electricity demand peaks so that you can save money on coincident demand and transmission charges. Our prediction services for the summer of 2014 will cover:

  • Mid-Atlantic: PJM's 5CP Hours
  • New England: ISO-NE's ICAP Hour
  • Texas: ERCOT's 4CP Intervals

If you are located in one of these regions, we might be able to help you reduce your electricity bills by up to 20%.

About coincident peak charges

If you represent a large commercial or industrial facility that buys power from a retailer other than your utility, a portion of your bill is probably based on your company's electricity usage at the same time that the grid reaches peak demand. In the United States, this tends to occur during hot summer afternoons when air conditioning loads are high.

The specific time periods that are classified as peak demand are identified after-the-fact using a formula specific to your region's grid operator. The peak hour determination depends on on the entire grid's demand, rather than your individual facility's demand. Here is a quick summary of the rules, by region:

Region Operator Method
Mid-Atlantic PJM Five coincident peak (5CP) hours. Each year, PJM looks back at the months from June through September, and picks the five highest demand hours occurring on distinct days.
New England ISO New England Installed Capacity - a.k.a the "ICAP Hour". Each year, ISO New England looks back at the months from June through September, and picks the single highest demand hour of the summer.
Texas ERCOT Four coincident peak (4CP) intervals. Each month from June through September, ERCOT picks the single highest demand 15-minute interval for that month.

How our service works

Coincident peaks are not known with certainty until the end of the summer. However, with an understanding of demand patterns and weather effects, it's possible to accurately forecast high risk periods. GridReason uses modern statistical and machine learning tools to estimate the probability of a coincident peak occurring at any given time during the summer.

Customers can access our predictions via our online dashboard, or by SMS/email notifications. Here is an example of one of our charts, which shows a load forecast as well as an hour-by-hour estimate of the chance of a peak:

We constantly monitor grid conditions and weather forecasts to keep our predictions up to date. Charts such as the one above are updated at least once an hour. We also offer a notification service that alerts our customers of upcoming peak demand periods.
