At times of high national electricity demand, or if a major power station fails, Flexitricity turns down Norish’s cooling plant for short periods to reduce the stress on the electricity network.
Critical temperatures are monitored to ensure the integrity of the stored product. This allows Norish to earn extra revenue without disrupting its normal business operations.
Norish engineers monitor the plant at all times but the whole STOR process is automated and managed by Flexitricity.
There has also been a significant environmental impact. Every megawatt of capacity connected to Flexitricity is a megawatt that does not have to be held in reserve elsewhere – reducing emissions by between 300 to 750 tonnes of CO2 per megawatt per annum.
In addition, the flexibility provided by Norish is vital in helping National Grid manage the increased renewable generation in the system.
