Pinguin UK keeps cool and creates value from flexible power
Through Demand Response programmes, Pinguin is receiving payments from the electricity transmission system operator for its flexible power. REstore enables this by curtailing the compressors and fans used to chill the company’s cold stores for short periods – all achieved without impacting overall production and quality.
Pinguin UK is a pioneer and a market leader in healthy food products. For 50 years, the company has been processing a wide range of freshly harvested fruit and vegetables into fresh frozen products (vegetables, herbs, fruit and vegetable-based culinary preparations) for all the major supermarkets, foodservice providers and industry.
The Pinguin manufacturing site in Kings Lynn was built in the 1960s but has undergone several refurbishments and developments since then. The freezing production line is capable of dealing with 16 tonnes of vegetables per hour and the site has a 10 000 pallet cold store.
“It’s a win-win. We don’t affect our product quality and we save money on our energy costs”Paul Spurrell, Engineering Manager, Pinguin
Pinguin UK is extremely sensitive to energy price changes as this forms a significant part of day to day running costs. As such, they were keen to explore ways to keep energy costs down.
However, Pinguin needed assurances that their product quality would be unaffected and that strict guidelines would be followed to meet industry standards. This included concerns around the speed at which assets could be curtailed and the potential subsequent impact on maintenance.
Working closely with the engineering team at Pinguin, REstore identified the site's compressors and fans as sources of flexible power. Industrial boundaries were agreed that meant an activation could not occur if either the cold store temperature was above -18°C or was in defrost setting. These parameters were programmed into the control system ensuring that Pinguin could take advantage of Demand Response payments with no impact on productivity.
Using REstore’s patented FlexPond™ platform, the compressors and fans are now able to automatically curtail within the 30 minute request period of the Demand Response programme with no impact on asset performance and maintenance.
Pinguin is so comfortable with the process that, following REstore’s recommendation, these assets will now be entered in dFFR (dynamic Firm Frequency Response) which requires a response of under 10 seconds. In turn, this will more than double the Demand Response payments Pinguin receive every year.
