Trimark says it has certified the first SEL-734 California Independent System Operation (CAISO) meters from Schweitzer Engineering Laboratories Inc. (SEL) to be installed for renewable power generation in California.

Two SEL-734 meters at the NRG Alpine Solar facility in Lancaster, Calif., have now been CAISO-certified. These meters monitor a project that will generate 66 MW of power. Trimark was contracted to provide meter programming, inspection and CAISO meter certification for the project.

Before certifying the meters for CAISO, Trimark conducted a final inspection of the meter installation and sealed all applicable meter points as required by CAISO inspection and testing protocols. The company also finalized the required CAISO meter certification forms, site verification data sheets, single line drawings, three line drawings, scheme description and all applicable calculation sheets.
