What your output is worth, hour by hour

Solar, wind, hydro, landfill gas and CHP owners see output, the price they actually capture, curtailment exposure and certificate value in one place. When you want to sell energy or certificates, you tell us what you have.

Small producers

144 plants in ERCOT, up to 100 MW

The console maps every operating solar, wind, hydro and landfill gas plant of 100 MW or less in ERCOT from EIA-860M, and models which sites each one could supply. In Northern Italy it maps 3,576 small plants in Lombardy and Emilia-Romagna.

Describe what you could sell. Volume, start date, term, price structure and certificates.
Reviewed by a person. We read every request and reply with the options we see, or tell you if we have none yet.
No commitment. A request is an enquiry, not an offer or a contract.
