Utility scale energy storage Natural Power helps to de-risk utility scale energy storage in California

Battery Storage

What was the aim of the work?

Natural Power worked with one of the market’s largest independent power producers to provide technical due diligence on the acquisition of a portfolio of grid-scale energy storage assets.

What was the outcome?

With approximately 90 MW of capacity and energy storage projects offering a range of services, such as resource adequacy, frequency response, and capacity the portfolio provided many opportunities for the client and also a complex mix of technical and financial risks to navigate. Natural Power’s technical team quickly deployed to evaluate key risks facing many of today’s energy storage projects, such as capacity degradation and suitability for participation in an optimized combination of revenue streams. The team also examined project design and technology selections in the context of rapidly evolving codes and standards.

What did Natural Power do to get this result?

Leveraging this expertise and in-depth review, Natural Power was able to help the client negotiate improved warranty coverage and a repowering program to ensure that the battery systems could meet the portfolio’s financial projections, even under the kinds of increased degradation rates that often come with maximizing disparate revenue streams.
