Meaning
Rate agreement between a provider and a consumer that offers lower costs in exchange for the right to limit service during peaks. Accepting a utility curtailment tariff allows a factory to reduce its overhead by participating in demand response programs. It defines the specific notice period and the maximum number of hours that a site may be powered down.
Contract Provision
Penalties for failing to reduce load when requested can be severe and often exceed the annual savings from the lower rate. The utility curtailment tariff creates a financial incentive for companies to maintain backup power or flexible production schedules.
Grid Reliability
Providing the utility with the ability to shed load helps prevent wide scale blackouts during extreme weather or periods of high grid stress. While the utility curtailment tariff benefits the provider, it forces the manufacturer to balance energy savings against the risk of a production stoppage. Audit teams review these interruptions to calculate the true cost of the discounted power.
Operational Cost
Regular calls for reduction can disrupt the demonstrated rate of a production line. Investing in on-site storage can mitigate the impact of the utility curtailment tariff on the bottom line. This pricing model represents a trade between operational certainty and energy expense.
