Summary of energy savings
Industrial park substation
$14,000 in annual energy savings from power quality adjustments
Measurements at the substation transformer feeding the industrial park identified energy losses of 353.6 kWh/day (average value) because of reactive power. Solution: Install time-control relays to disconnect capacitor bank at night.
$50,000 in annual energy savings
Surveys of six key areas, including the engine plant and the car assembly plant, showed significant energy waste because of power quality.
Solutions: Install capacitors and regulation controls and upgrade transformers.
