Common use of Active Power service Clause in Contracts

Active Power service. The Active Power service relates to the active power generated from the participating DER unit. After receiving an instruction, it will need to be capable of responding by automatically ramping the active power generated up and/or down according to the DERMS instruction and within the plant limitations. This service is expected to manage transmission constraints and to support technical and commercial optimisation and dispatch. It will be exercised on the day in real-time depending on the cost compared to other options available to the System Operator. The provision of this service means that the plant should be ready to change its active power output upon an instruction from UK Power Networks via the DERMS. The plants response should be automatic and within its pre-defined limits and ramp rates.
