How to Participate

If your commercial or industrial business has onsite back-up generation or equipment that can have its electricity consumption reduced for brief periods, then Demand Response could be a viable opportunity for your business.

Suitable non-critical equipment may include air conditioning, ventilation, electric heating, water chillers, fans, pumps, and other interruptible loads.

If you’d like to discuss your site’s suitability for Demand Response, our technical team are happy to provide a no-obligation technical discovery meeting. Simply get in touch and we’ll do the rest.

“As a large energy user, who is in pursuit of environmental excellence through our product development, we wanted to do more to support carbon reduction and boost renewable utilisation nationally. I engaged with VIOTAS Technical Sales to understand how Mannok could become an active grid participant by using our large flexible loads to provide Frequency Response services to the Irish grid. VIOTAS had the knowledge to provide me with the market details, road map, and confidence to proceed with our ambition to participate in the Frequency Response Market.”
