California Independent System Operator

from Wikipedia, the free encyclopedia

The California Independent System Operator (CAISO) is one of nine independent, national transmission system operators in the USA and Canada . CAISO is responsible for operating the transmission network in much of California and a small part of Nevada . CAISO is a non-profit organization that is regulated by federal agencies such as the FERC .

General

The power grid in California and Nevada is part of Western Interconnection (WI), one of four interconnected networks in the United States and Canada. In California there are eight (or nine) transmission network operators (including CAISO) ( balancing authority ), and there are 38 in total in the field of WI.

history

CAISO was founded in 1998. CAISO and the neighboring PacifiCorp have been working together in an Energy Imbalance Market (EIM) since November 2014 .

Members

CAISO has more than 100 power producers and network operators, including Pacific Gas and Electric , San Diego Gas & Electric and Southern California Edison . The technical facilities of the transmission network, such as high-voltage lines and substations, belong to the respective companies.

Before a new generator can market its electricity in the CAISO network, it must pass an interconnection study process , which can take two years or more. The subsequent steps, such as signing contracts and installing measuring and telemetry equipment, take at least another six months.

Key figures

In 2014, CAISO had almost 600 employees and a budget of 198 million  US dollars . With an estimated transmission volume of 247.3 billion  kWh for 2014, this corresponds to costs of USD 0.801  per MWh (or 0.0801 US cents per kWh).

Around 30 million customers are supplied in the network operated by CAISO. The network includes high voltage power lines with a length of 41,800 km (26,000 miles). The installed capacity in the CAISO area is 57,124 (or 60,000) MW. The peak load is 50,000 MW. Approx. 260 billion kWh are transmitted over the CAISO network each year.

CAISO operates two control centers, one at the headquarters in Folsom and the other in Alhambra .
