Sample Projects

Transmission system planning and operations have never been more challenging. Increasing penetration of variable generation requires new operating protocols and imposes costs on transmission providers due to increased need for flexible generation, while queue reforms and new regional planning efforts under the auspices of FERC Order 1000 increase the complexity of transmission planning decisions. E3’s thorough understanding of transmission system operations and planning, combined with our up-to-date knowledge of energy policy and regulatory developments, places us in a unique position to help clients grapple with these and other important questions. In addition, we provide support through the entire process, frequently serving as expert witnesses in regulatory cases involving siting or tariff administration

Our transmission services include:

  • Transmission planning
  • Transmission project needs assessment
  • Projections of transmission project benefits
  • Assessment of “non-wires” alternatives to transmission investments
  • Regulatory and permitting support
  • Renewable integration needs and cost assessment
  • Transmission tariff and rate design
  • Development of cost allocation mechanisms
  • FERC Order 1000 support
  • Expert witness testimony
