ERCOT 15 Minute Pricing

Hi Paul - I'm setting up a template for PV plus storage for our customers in Texas, behind Centerpoint, Oncor and AEP primarily. We're looking at a hybrid BTM system, however also providing Ancillary Services and mining energy arbitrage opportunities also thru. the QSE's that we work with. In your financial models where would Ancillary Services and Energy Arbitrage revenues be input?  Appreciate your thoughts.

Hi Robert,

SAM's behind-the-meter (BTM) financial models assume that the value of electricity is based on a reduction in the annual electricity bill, so they do not model project revenue. However, you can model value in addition to the bill savings using inputs on the Incentives page for incentives earned on a $ per kWh of production basis or $ kW of installed capacity basis.

SAM's PPA financial models, such as the Single Owner model assume the value of electricity is based on electricity sales at a negotiated power price with optional time-of-delivery adjustments. The Single Owner model's Revenue page provides inputs for additional revenue streams for capacity payments and/or curtailment payments.

SAM's Merchant Plant financial model is for projects that sell electricity at hourly our subhourly market rates. The Revenue page for this  model has inputs for energy market and up to three ancillary service markets, each with its own inputs for time-series cleared capacity and time series power price.

Best regards,
Paul.
