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 |
