Value of demand flexibility for providing ancillary services: A case for social housing in the Irish DS3 market

This paper evaluates the potential of consumer flexibility from a portfolio of heat loads, solar panels and batteries in Social Housing to provide ancillary services. We propose two new ancillary service products: Turn-Up-Demand (TUD) and Turn-Down-Demand (TDD). We ran simulations for a complete year. The buffer-tank scenario provided earnings of 146 pound/year for an average consumer. Finally, we propose a new policy called the Vulnerable Consumer Priority in Administering System Services (VCPASS) and the use of Heat-as-a-Service (HaaS) to fund the replacement of oil-boilers with heat pumps in fuel poor homes with a rate of 9.99p/kWh of heat for a payback period of 15 years.
