When electricity demand increases beyond forecasted levels or supply is affected by a power station shutting down unexpectedly, System Operators like EirGrid turn to reserve supplies to make up the shortfall. These backup supplies tend to be the most polluting and expensive power stations on the grid.
Demand response provides an alternative reserve service that is cost effective and clean. Company sites are paid to either turn down their electricity demand or generate additional power using their on-site energy assets to meet the shortfall in supply. These reserve services are then used until the balance is resumed or slower-to-respond power stations can take over.
In Ireland, the demand side management programme is called Demand Side Units or DSU. For a site to be able to use their onsite energy assets, the asset must be able to respond within 30 minutes. This response time is slower than those required to participate in frequency response programmes, so a wider range of assets can be used in DSM.
Currently DSU pays approximately €60,000 per MW for 24/7/365 participation.
Our clients’ sites utilise a wide range of energy assets including chillers, air conditioning units, lighting, fans, pumps, combined heading and power systems (CHPs), diesel generators and much more to:
