Market-leading Fast Frequency Response Services

Access the quickest and most lucrative Demand Side market products

FCAS involves fast and short changes in electricity use to keep the electrical frequency of the power grid close to 50Hz. This helps to maintain stable operation of the grid and prevent power outages.
The faster participants in FCAS can react to grid power system needs, the more they can earn. Our market-leading Fast Frequency Response technology, VIO Link, reduces the time it takes your equipment to respond to power system requirements from minutes to milliseconds by monitoring the state of the grid 8,000 times per second.

Choosing VIOTAS means your business can access the fastest and most lucrative market products and futureproof against greater frequency response performance requirements.
VIOTAS can provide both FCAS Raise (reduction in electricity use) and FCAS Lower (increase in electricity use) to our customers, depending on the type of equipment present at the site.

Not only are you adding an additional revenue stream to your bottom line, you are helping to grow sustainable and renewable energy usage across the grid and supporting your green credentials.
