California Lending for Energy and Environmental Needs (CLEEN) Center

IBank established the California Lending for Energy and Environmental Needs (CLEEN) Center to encourage public and private investments. The CLEEN Center utilizes IBank’s access to capital markets for clean energy and energy efficiency projects and will help drive energy related projects for State and local governments in California through the Statewide Energy Efficiency Program (SWEEP).

IBank is an integral part of protecting California’s (State) environment and vast natural resources by offering financing that helps achieve the State’s greenhouse gas reduction goals. At the same time, IBank enhances the quality of life our State is known for by promoting and stimulating economic growth, creating clean energy jobs, protecting and caring for the environment and revitalizing communities.

Program Objectives

  • Provide low-cost financing vehicles, which reduce the cost of clean energy and energy efficiency projects.
  • Leverage existing public programs and funds to attract private sector investment.
