Renewable Portfolio Standard (RPS)


RPS approved by Roseville City Council February 19, 2003

Roseville Electric RPS Objectives

  • Meet the state mandate to encourage renewable resources, especially wind and photovoltaics
  • Maintain reliable overall energy supply portfolio
  • Strive for environmental improvement
  • Minimize adverse impact of acquiring new renewable energy resources on customer electric rates

Roseville Electric Qualified RPS Resources
Renewable resources are defined as non-fossil fueled electric generating resources, including hydroelectric.

Roseville Electric RPS Target
Roseville Electric resource mix will have a minimum of 20% renewable resources.

Strategies for Meeting Roseville’s RPS Objectives
Increase renewable resources in Roseville during the next five years by 5 megawatts, one of which to be sited locally

Reporting RPS Performance
Roseville Electric will report in the annual power content label to be distributed to all Roseville Electric customers:

  • Expenditure of public benefits funds collected for renewable energy resource development
  • The resource mix by fuel type including each type of renewable resource

Ongoing Review of Roseville Electric RPS
An ongoing five-year review of the RPS will address changes in the Roseville Electric power portfolio including local generation versus market power purchases and potential changes in the renewable energy technologies.


California Legislative Mandates for Renewable Portfolio Standards

SB 1078 was signed into law September 12, 2002. This law defines qualified renewable energy resources and sets forth the following renewable portfolio standard (RPS) for retail electric sellers other than municipal utilities:

  • 20% of retail electric sales must be supplied by renewable resources by 12/31/17.
  • Retail sellers must increase renewable supply by at least 1% per year until the 20% target is reached.

Roseville Electric is a municipal electric utility. SB 1078 outlines the following as RPS requirements for municipal electric utilities:

  • Each municipal governing board is responsible for implementing and enforcing a local RPS that
    • “recognizes the Legislature’s intent to encourage renewable resources, especially wind and photovoltaic, taking into consideration the effect on rates, reliability, financial resources and the goal of environmental improvement”
  • Each municipal utility must report annually to its customers:
    • Expenditure of public benefits funds collected for renewable energy resource development; and,
    • The resource mix by fuel type including each type of renewable resource
  • Each municipal utility governing board must define the terms of its RPS. This would include the determination of the following:
    • what qualifies as a renewable resource (whether or not to count large hydro projects) and
    • the percentage of the total energy resources that are to be renewable, and
    • how quickly you plan to meet that goal.
