Case Studies

Ascend quantified value from both day-ahead and real-time energy market revenues, ancillary service revenues, and avoided resource adequacy procurement.
  • The Clean Energy RFO received over 100 offers including wind, solar and storage hybrid, geothermal, small hydro, and biofuel projects. Ascend evaluated and rank-ordered the most economic projects for CPA to procure 1-2 million megawatt-hours (MWh) annually of clean renewable energy.
  • The Reliability RFO received 70 offers for 46 stand-alone battery projects. Ascend used its leading analytics tools to quickly calculate the economic value of each project to derive CPA's short list of projects for negotiation.
  • Developed tools to automate the screening and evaluation of qualitative project criteria, in addition to economic valuation
  • Provided a complete end-to-end service, including marketing, bidder communication, administration, and project valuations
  • Used Ascend-generated forecasts of day-ahead and real-time electricity prices, including capture of key fundamental changes in CAISO price dynamics such as increased volatility, changing price shapes, and evolving basis risk.
