Electric Power Engineers, Inc. provides unparalleled consulting services in studying the technical and economic feasibility as well as engineering and design of distributed generation. EPE’s experience with distribution system studies since 1968, bonded with our expertise in renewable generation integration since 1995, provides the skills necessary to address all of the following when it comes to integrating distributed generation on the grid:
➤ Study of the distribution grid and its ability to integrate new renewable or other generation
➤ Voltage flicker analysis and compliance with IEEE 519 and IEC 61400-21
➤ Thermal loading analysis
➤ Interconnection application process
➤ Review of compliance with good utility practice criteria
➤ Design/Engineering/Procurement for renewable generators including solar, wind and biomass
➤ Feasibility studies:
Technical and Financial review of feasibility of distributed generation.

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

Generator Grid Interconnection

EPE will assist clients in all stages of the grid interconnection process:
• Applications for Interconnection
• Electrical interconnection system design
• One-line diagrams
• Technical support
• Interface discussions with transmission providers
• Critical review of feasibility and system impact studies
• Review of Interconnection Agreements (IA)
• Responses to Request for Proposals (RFP) for the purchase of renewable generation

Plant Design / Engineering / Procurement

EPE can act as owner’s engineer for generation developers, overseeing engineering, design and procurement aspects of their projects. EPE will specifically provide the following services:
• Substation and transmission interconnection one-line diagrams and specifications.
• Collection system design
• Specification documents for design / build contractor bids for:
➤ Substations
➤ Power transformers
➤ Electrical Balance of Plant (BOP)
• Evaluation of bids
• Review of technical compliance with transmission provider IA
