About

We are experts in the design and operation of distributed energy resources (DER) who are driven by a commitment to help electric utilities navigate the clean energy transition in a way that meets society’s need for a reliable and affordable power system.

 

Our analyses and leadership have supported numerous power system operators in gaining regulatory approval for energy storage and other DER projects, including multiple utility rate-based projects.

 

We deliver a unique engagement that transforms our clients by respecting and empowering practitioners, supporting them with tools and experience, and challenging them to achieve more with DERs as part of their normal operations.

 

We have direct experience in electric utility engineering and operations, advanced power system modelling and analytics, DER technology creation focused on energy storage utilization, DER deployment, and organizational leadership and change.

Our Mission

To accelerate the decarbonization of the electric grid by providing engineering, analytics, and procurement capabilities that enable utilities to make distributed energy resources a normal part of a safe, reliable, low-cost electric grid.
