Representative Projects


Stanton Energy Reliability Center, California

E3 served as the Independent Engineer for the Stanton Energy Reliability Center (SERC), a state-of-the-art hybrid energy storage system that will consist of two General Electric (GE) LM6000 based EGT®s located in Stanton, CA. EGT® refers to the Hybrid technology jointly developed by General Electric International, Inc. (GE) and Wellhead Power Solutions. The EGT® combines a turbine with an integrated battery storage system operated by a proprietary software system. SERC will provide 98 MW (nominal) of hybrid energy storage capacity. E3 is currently providing construction monitoring on the project.

GlassPoint Solar Enhanced Oil Recovery, California

E3 was engaged by a confidential client to evaluate GlassPoint’s solar technology, which is specifically designed to produce steam for injection into oilfields for enhanced recovery of heavier crude oils. The technology has been implemented for Oman Oil Company in Oman at one of their developments, and they are planning the next phase of implementation. E3 was asked to evaluate this an investment opportunity, reviewing the technology, and examining project financing opportunities for the future projects. E3 visited the Oman site to verify the operation and to understand how well the technology works on a commercial scale. The technology is undergoing some enhancements, and E3 evaluated the pilot facilities and development laboratories in San Jose and Bakersfield, California. E3 also reviewed the process and mechanical designs for both the original technology and the new version. E3 reviewed capital cost estimates for the old and new versions of the technology. In addition, several other early stage projects were reviewed in detail, including process design, steam production estimates, financial pro-forma inputs, environmental, construction contracts, agreements with major oil companies and other aspects. The total value of all the projects reviewed was more than $5 billion.

AES Distributed Energy – PV+Storage Portfolio, Massachusetts

E3 was the Independent Engineer to support the tax equity investment and debt financing of a portfolio of solar PV plus energy storage projects in Massachusetts. The projects were designed for the Solar Massachusetts Renewable Target (SMART) Program.  The scope for E3 included a comprehensive review and report covering major equipment, technical design review, detailed resource evaluation, battery dispatch model, warranty review, interconnection agreement, engineering, procurement and construction (EPC) agreement, O&M costs, and the financial model.
