The CalPeak – Enterprise project was reviewed under Public Resources Code section 25705, which granted the California Energy Commission (Energy Commission) emergency permitting authority, and Executive Order D-26-01, issued February 8, 2001 and Executive Order D-28-01 issued on March 7, 2001. In Executive Order D-26-01 and D-28-01, the Governor ordered the Energy Commission and other relevant state and local agencies to expedite review of proposed thermal power plants for construction and operation on an emergency basis by September 30, 2001. The Governor also declared that these projects were emergency projects under Public Resources Code section 21080(b)(4), and are thereby exempt from the requirements of the California Environmental Quality Act.

On June 6, 2001, the Energy Commission approved the nominal 49.5 megawatt, simple-cycle, natural gas-fired peaking CalPeak Enterprise (Enterprise) project. Commercial operation began on September 30, 2001.

Enterprise consists of one FT8 Pratt & Whitney Twinpac turbine generator and associated facilities on approximately 2.95 acres located at the southern end of North Enterprise Street in the City of Escondido, San Diego County. The project incorporates selective catalytic reduction to reduce project emissions.

The Energy Commission Decision included a provision that would allow for the certification to be extended for the life of the project, provided that the conditions of certification were current and in compliance, the project was permanent in nature, and air emission credits were in place. On April 11, 2012, the Energy Commission approved the extension of the Enterprise project for the life of the facility, until such time that it ceases operations and commences permanent closure activities.

Small Power Plant Exemption Evaluation Process

The SPPE process allows projects between 50 and 100 MW to proceed with local approval rather than requiring an Energy Commission license. This exemption from the Energy Commission licensing process can be applied to projects that would not create a substantial adverse impact on the environment or energy resources. The Energy Commission acts as the lead agency under the California Environmental Quality Act (CEQA) and will prepare an Initial Study and Mitigated Negative Declaration that examines public health and safety, along with environmental impacts of the proposed project, including all related facilities such as electric transmission lines, natural gas and water pipelines. If the exemption is granted, the applicant would still need to secure the appropriate licenses and permits from relevant local, state, and federal agencies.
