A term used to describe a customers usage prior to taking action to reduce its usage as requested. The baseline is determined differently in different demand response programs. In New York, the baseline is defined as the Average Coincident Load ("ACL") and is calculated by taking the top 40 peak hours during the 4 middle months of a capability period and averaging the company's 20 highest usage hours. The 4 middle months for the summer capability period is June, July, August and Sept. The 4 middle months for the winter capability period is Dec, Jan, Feb and March. In other markets, a Customer Baseline (CBL) approach is used, which generally involves the highest 3 or 5 days from the prior 10 weekdays, with certain exclusions.
Period of complete electric power loss to a widespread area
Period of electric power loss to pockets of customers, caused by a state of "poor power quality", in which the utility company may reduce electric line voltage in efforts to deliver more electricity to meet increased demand; or the utility may even curtail electric power supply to blocks of customers to meet demand. A reduction in voltage can compromise facility equipment that requires stable, non-fluctuating voltage supply.
