Fast Frequency Response
New technologies present an opportunity to provide FFR service.
The AESO has launched a Fast Frequency Response (FFR) from new technology pilot procurement competition (FFR Pilot Competition) targeted at procuring service from any new technology capable of meeting the FFR eligibility and technical requirements. The AESO has announced the pilot through its Energy Storage Roadmap progress updates.
The AESO has coordinated with the Market Surveillance Administrator (MSA) regarding enabling provision of the service from new technology (other than load) within the current ISO Rules for the duration of the pilot and has posted a letter that provides further detail.
FFR Pilot Competition
The AESO is aiming to procure a target volume of 20 MW and may procure up to 40 MW of FFR service through a single-stage open procurement, which includes pricing as a part of the proposal.
The FFR requirements for pilot participants are based on LSSi but have been adapted for new technology, such as energy storage. A minimum capacity of 5 MW is required to participate, with the facility connected to the Alberta Interconnected Electric System via either transmission or distribution.
Service providers need to respond within 12 cycles (0.2 seconds) when a system frequency of 59.5 Hz is detected. A fast increase in real power output is expected in response to an underfrequency event. Underfrequency detection and event recording is also required to provide the service, and a SCADA system will be used to participate in the service.
The FFR Pilot Competition launched on March 24, 2021, and the proposal submission deadline was May 3, 2021. Contracts are expected to be awarded to successful bidders in mid-2021. A 12-month service period for each service provider is expected to start as early as Q3 2021 or as late as Q1 2022.
