Energy Resource Procurement
with Modern Analytics

Ascend provides end-to-end support for the energy procurement process, including capturing the value of renewables and storage for the system dynamics of tomorrow. Utilities, retailers, and Community Choice Aggregators turn to Ascend Analytics to implement efficient RFO/RFP processes that support intelligent and defendable risk-based decisions on behalf of their customers.

Capture the value of renewables and storage

Managing the RFP/RFO Process
the Ascend Approach offers:

Full-service procurement with an experienced team of analysts that have helped our customers procure over 10 million megawatt-hours per year of renewables and 500 MW of battery storage capacity. Ascend's industry-leading software suite provides the capabilities for selecting the best resources through:
    • Capturing the value of flexible resources to day-ahead, real-time (sub-hourly), and ancillary services.
    • Evaluation of both demand and supply-side resources on a level playing field. These include demand response, energy efficiency, behind-the-meter solar and storage, electric vehicle smart charging, as well as utility-scale renewables, storage, and traditional thermal resources.
    • Evaluation of risk through simulation across a range of possible futures rather than a single deterministic one.
    • Simulation of nodal prices to account for basis risk and renewable saturation in specific areas.
    • Access to Ascend's proprietary market price forecasts that capture changing market fundamentals driven by renewable and battery adoption such as increasing volatility, changing price shapes, and real-time price spike patterns.
    • Seamless process automation for rapid validation and valuation of bids. Valuation results turned around in weeks, NOT months.
    • Web hosting, project management, and bidder engagement.
    • One of the industry's largest database of reputable project developers for easy marketing.

Resource RFO Process

Risk-Based Decision Making
with Ascend

Signing PPA contracts can be a risky engagement, locking in purchase obligations for extended time periods. While perfect foresight remains impossible, Ascend's valuation approach assesses and mitigates the primary risks:

Historical Bias

Ascend's forecasting approach accounts for emerging market dynamics associated with renewable penetration while remaining firmly grounded in long-run economic equilibrium. This approach prevents being overly anchored to historical price behavior while also not overweighing the present or the near-term future.

Basis Risk

Ascend's models simulate nodal prices and their correlation with weather and renewable output, thus accounting for price depression at geographic locations with high renewable penetrations. This approach avoids overvaluing resources at saturated locations.


Ascend's stochastic modeling accounts for the hourly, daily, seasonal, and annual variation in renewable generation profiles, thus providing a valuation under realistic conditions rather than averaged ones. This approach allows quantifying variation in revenues, market exposure, loss of load, carbon impacts, and other metrics affected by the variable output from renewables.
