Summary

The Charles Wells site had an estimated annual energy expenditure of c£3.5 million and energy usage or e­fficiency had not been a priority. JRP Solutions were engaged to support the energy management activities of the site’s engineering team by providing focussed and specialist resources.

JRP developed an initial Site Energy Reduction Plan containing around 30 prioritised energy reduction opportunities with a potential cost reduction of over £400,000 per year and worked with the Wells & Young’s engineering team to develop business cases and plans for financial approval for the following projects:

• Improving and repairing the insulation of steam pipework around the site and the boilers themselves.
• De-commissioning the economiser on Boiler 3.

(Both these projects have subsequently been implemented and are delivering energy and cost savings.)

JRP:

• Developed the brief for a comprehensive survey of the steam traps and steam distribution network by Spirax-Sarco.
• Carried out a review of the sub-metering system, and helped to develop a new metering strategy
• Completed a plant condition survey of the CO2 recovery plant, and specified and sourced CO2 metering.
• Carried out a detailed survey of the Hop Store and identified opportunities to reduce costs and improve the storage facility.
• Analysed the nitrogen meter data and identified that a large proportion of the nitrogen demand was not being metered Consequently, two of the meters were relocated to the Keg Plant and Brewhouse which confirmed these two areas to be high nitrogen consumers Over 90% of the nitrogen use can now be accounted for.
• Identified the most appropriate method to supply the correct grade gases to the process (both CO2 and N2) by the most economic methods This information is now supporting the development and implementation of a nitrogen supply strategy which will ensure that the brewery has su­fficient quantities.
