Use this node to get the predicted prices (cents/kWh) for the next day (24 hours). Run the following command in the root directory of your Node-RED install npm install node-red-contrib-comed-rrtp Since Hourly Pricing participants pay the market price of electricity, they are actually being paid to use electricity during negative priced hours. In the market, some types of electricity generators cannot or prefer not to reduce electricity output for short periods of time when demand is insufficient, and as a result some generators may provide electricity to the market at prices below zero. This typically occurs in the middle of the night and under certain circumstances when electricity supply is far greater than demand. Negative Prices: With real-time hourly market prices, it is possible for the price of electricity to be negative for short periods of time. These are distribution loss factors, a system average uncollectable factor, and an incremental uncollectable loss factor. There are slight differences between the PJM 5-minute prices and the ComEd 5-minute prices because of adjustments that ComEd passes through to customers. ComEd RRTP customers are billed based on the PJM real-time hourly market prices. The current hour average price is the real-time average of the current hour’s 5-minute prices. The ComEd real-time hourly market price is determined by the average of the twelve 5-minute prices from that hour, and so the averaged real-time hourly price is not known until after the hour has passed. These nodes scrape the ComEd RRTP site to obtain real-time and predicted pricing information. Node-Red nodes for obtaining Commonwealth Edison's Residential Real-Time Pricing (RRTP) information.
