Renewables & Alternative Fuels

Due Diligence & Technical Services

As a result of the specialized and diverse experience of our select group of employees, E3 has worked on renewable energy projects including wind, geothermal, solar (CSP and PV), hydroelectric, landfill gas, waste-to-energy, biomass, biomass to fuels (both hydrolysis & fermentation and gasification & catalytic), biodiesel, and anaerobic digestion projects.

Alternative Fuels

In the biofuels and alternative energies sector, E3 and its professionals have worked on alternative fuels engagements (hydrolysis & fermentation and gasification & catalytic), biodiesel, and anaerobic digestion projects. We have supported engagements on projects ranging from ethanol production facilities up to 100 million gallons per year, biodiesel facilities up to 180 million gallons per year. Our assignments have included technology assessments, environmental assessments and permitting, project planning, feasibility assessments, technical and economic due diligence, construction monitoring, and operations and maintenance reviews.

Biomass

E3 has reviewed the development, construction, and operation of a variety of biomass-fueled projects including biomass projects combustion projects ranging in size from 6 MWs to 75 MW and wood pelletizing projects, among others. E3’s team of biomass experts understands what makes a project technically viable and financially feasible.

Geothermal

E3’s staff has provided expertise on a variety of geothermal projects totaling more than 2,000 MW of electric capacity. The services provided include pre-financing due diligence, acquisition and divestiture assistance, project turnaround, asset valuations and appraisals, operations management consulting, environmental permitting and site assessments, development assistance, and dispute resolution support. Our team members have worked with several technologies, including single flash, dual flash, triple flash, Ormat Binary Cycle, Ormat Hybrid Cycle utilizing Fuji and Mitsubishi turbines, and Turbine Air Systems (TAS) binary power cycle.

Hydropower

E3 has reviewed the development, construction, and operation of a variety of hydropower projects. We work with several highly experienced sub consultants who provide additional expertise related to hydroelectric plant design and operations and hydro resource assessments. We also draw upon the shared resources of our parent company, NAES, to provide in-depth operation and maintenance services.

Solar Power

E3 has reviewed the development, construction, and operation of everything from single solar installations to large portfolios consisting of residential solar leases. Our solar team understands what makes a solar project technically viable and financially feasible.

Wind Power

E3 has reviewed the development, construction, and operation of wind farms ranging in size from less than 10 MWs to portfolios of more than 900 MWs. We have worked with the major turbine manufacturers and understand what makes a wind project both technical viable and financially feasible.

Representative Projects


Conifex

AES Distributed Generation Warehouse Project, Nationwide

E3 served as the Independent Engineer to support the acquisition and financing of a portfolio of residential photovoltaic (PV) solar leases for AES Distributed Generation, formerly Main Street Power, and their Joint Venture with Morgan Stanley, MySolar. For this unique project, E3 developed an innovative sampling method and lease evaluation process that will provide statistical data on the compliance of the leases to the lease criteria. This unique approach was applied to thousands of residential solar leases, with only a statistical sample of projects being evaluated. For these leases, E3 conducted a comprehensive review of approximately 200 criteria, including the rooftop installation detail, solar resource, shading analysis, net metering regulation compliance, electrical design, inverter reserves, 1603 compliance, interconnection requirements, equipment selection, warranties, performance guarantees, construction agreements, and other aspects.


Conifex

Myriant Lake Providence Succinic Acid Plant, Louisiana

E3 served as the Independent Engineer supporting the construction and term financing of a succinic acid and ammonium sulfate production plant in Lake Providence, Louisiana. The plant uses novel fermentation processes to produce high-value industrial chemicals using low-cost non-petroleum feedstocks. E3 reviewed the process technology, construction plans, capital and production costs, permitting requirements and financial projections. The facility was partially financed with commercial debt and received grants from the U.S. Department of Energy and the United States Department of Agriculture.


Conifex

Terra-Gen Voyager I Wind Project, California

E3 is currently serving as the Independent Engineer on behalf of project lenders to support the construction and term financing of this 130 MW wind project located in the Tehachapi Wind Resource Area of California.  The project is utilizing Vestas V112-3.45 WTGs.  E3’s services include a review of technology, status of permitting, construction contracts, construction costs and schedule, the wind resource study and production estimates, O&M costs, and interconnection requirements.
