Energy Storage Procurement Support

Project Slate + BESS

Phoventus was contracted by Recurrent Energy to provide engineering support in assessing the Energy Storage System (ESS) Integrators’ bids for the 45MW/180MWh Slate Project in Kings County, California. The quality and quantity of documents submitted by the bidders differed significantly. The level of conformance to the RFP was varied, and the underlying assumptions in each bid diverged from each other.

Phoventus homologated the proposals by decomposing each bid price into the major cost contributing factors and reproduced the normalized project’s cost over its lifetime. This analysis is available in form of a comparative workbook.

The integrator EPC cost, the civil work and implementation were reviewed. The level of detail regarding fault protection strategies provided by the bidders was reviewed.  Phoventus recommended short-listing bidders; and a more thorough analysis of the bids that followed.
