As demand for electricity in the western United States increases, stresses upon the aging power grid are intensifying. Computer models based on complex mathematical relationships are being developed to assist in understanding the impact of deregulation and market transformation. Frequency, load, and plant outage events data collected over the last several years. Analysis of these events was performed to determine frequency deviation and the systems inertial constant (M) during each event. Utilizing a theoretical relationship that relates system inertia to power loss, M was calculated for 157 events. The relationship of M to system wide load was then examined.
