EPE has been in the engineering consulting business since 1968 and has extensive experience in renewable energy projects, particularly wind. We assist our clients through all stages of renewable generation development: from initial site evaluation to generation grid interconnection. EPE has assisted dozens of wind and solar generation developers all across the US and internationally. We specialize in the evaluation of transmission grid export capacity, and will also act as Owner’s Engineer, coordinating engineering, procurement, and construction of projects.

At EPE, we understand and address all technical corner-stone
elements that are vital for the success of a renewable generation project.
➤ Over 50 renewable generation clients.
➤ Over 100 generator interconnection assessments per year.

Our experience is extensive in generation interconnection to the Electric Reliability Council of Texas (ERCOT), as well as Southwest Power Pool (SPP), Western Electricity Coordinating Council (WECC), Midwest Independent Transmission System Operator (MISO), and New York Independent System Operator (NYISO). At EPE, there are no geographical limitations to where our services can extend. We have worked on projects all across the United States as well as internationally.

Transmission Grid Evaluation

Availability of transmission is as essential to generation project development as the capability of the renewable resource. Without transmission, the energy cannot be delivered and sold to the market. At EPE we extensively address all the aspects of transmission grid evaluation:
• Generation Export Analysis
• Analysis of transmission deliverability across networks
• Generation Interconnection Feasibility Studies
• Short Circuit and Transient Stability
Analysis (System Impact) Studies
• All calculations use PSS/E & PowerWorld
• Latest models for the entire U.S. transmission grid
• Transmission mapping of resource sites
• Special investigation of transmission
grid interconnection solutions
• Review of transmission grid planned upgrades
• Review and impact analysis of queued
and other generation projects
• Recommendations on transmission upgrades and additions
• Evaluation of wheeling charges, congestion, and losses
• Estimation of electricity sales price
($/MWhr) using LMP analysis
• Analysis of voltage flicker on weak
transmission or distribution networks
