Resource Planning 2.0

Ascend is pioneering Resource Planning 2.0 for a more uncertain and interconnected world.

The energy landscape is undergoing fundamental change.  Renewables are being added to the grid at a rapid pace and changing market dynamics unlike anything in the past 100 years.  As times change, we need new tools and techniques to manage increasing uncertainty and variability.

Times have changed... Has your modeling kept pace?

New Paradigm

Resource Planning 2.0



  • Simulated weather that jointly drives load, renewables, and prices.


  • Comprehensively plan for capacity to meet peak load through simulated weather, outages, and renewable output n easy-to-interpret reliability planning metrics.


  • Determine increased flexible resource requirements due to variability in renewable generation.


  • Realistically capture uncertainty inherent in daily operations by simulating imperfect foresight in generation optimization.


  • Stochastic construct to capture "meaningful uncertainty" of emerging market dynamics and the impact of tomorrow's new structural drivers effect on supply and market price dynamics.

Ascend works with utilities throughout the US to develop innovative resource plans that balance the need to add renewables to comply with RPS requirements and add integration technologies such as batteries and sub-hourly operations. This helps maintain reliability and minimize costs for customers.

Writing of resource plans

Ascend charts a course for 100% renewables in Hawaii

HECO's Ascend-backed Power Supply Improvement Plan (PSIP) to achieve 100% renewables was approved after Ascend was brought in to address previous deficiencies.

Ascend provides Riverside with decision framework for Integrated Resources Plan

Ascend examined the biggest planning challenges of the day, including resource adequacy needs, RPS mandates, carbon emission goals, and risk metric objectives in Riverside's Integrated Resource Plan.

Ascend establishes industry best practices in NorthWestern Hydros acquisition

Ascend established "industry best practices" in NorthWestern's resource plan, providing detailed modeling, writing, and expert testimony in the Montana Supreme Court.

Ascend helps Duke Energy prepare for an influx of renewables

Duke relies on Ascend to help determine the net benefits of new renewable projects and resource mixes within a large portfolio.  Ascend probabilistically informs Duke of least-risk location of each project.


Flexibility and Reliability Requirements for LADWP

Los Angeles Department of Water and Power is using Ascend's PowerFlex tool to see how additional renewable capacity will impact flexibility and reliability requirements.
