Grid systems are integrating more renewables, creating system volatility
o Ireland, for example, has a goal of 75% non-synchronous generation on the grid at any time by 2020.
o Ireland also set a record for this on 9 April 2018, when it had 65% non-synchronous generation on the grid – the first power system in the world to do this.
Instantaneous stabilization of system frequency is becoming as important as ensuring long-term security of supply for decarbonizing grids.
o But this requires faster – near instantaneous – response.
EirGrid (the TSO) in Ireland have answered this call with the May 2018 launch of their DS3 program.
o Will this still be a business opportunity for C&I? Absolutely, if the assets and technology are right.
EirGrid’s Fast Frequency Response (FFR) service in its DS3 program push the limits of technology in energy.
o The required data transmission speed is less than 20 milliseconds, with a 2 millisecond time synchronization. This is the fastest data transmission speed possible in the energy world!
Therefore best assets for frequency response are fast-acting distributed energy resources
o Back-up generation, CHPs, storage, etc.
o These assets are prevalent everywhere – construction, transportation, healthcare, food processing, agriculture, etc.
Any business looking to invest in a fast-acting distributed energy resources should evaluate the opportunity for frequency response and factor this in to their energy strategy and management plans.
