Demand Side Unit

What is DSU?

Demand Side Unit is a service offered by Electric Ireland that gives businesses like yours the opportunity to earn significant extra monthly revenue simply by being available to reduce electricity consumption or self-supply from your own generator for short periods of time.

How it works

You decide how much and when you can deliver demand reduction or self-supply. Through the Single Electricity Market (SEM), we aggregate your availability to reduce consumption with other participants, and deliver all those reductions in bulk to Eirgrid, the national grid operator. The electricity market operator pays us. And we pay you.

How your business can provide demand reduction

  • Temporarily switching off, or re-scheduling, non-essential equipment/process
  • Through on-site generation
  • By reducing consumption of specific electrical equipment, such as aircon, chillers or pumps
