Esight Energy has revealed that its web-based monitoring and targeting (MandT) system has helped brewery Carlsberg UK reduce energy consumption by 10 per cent.

Carlsberg UK required a web-based MandT system for multiple plants and distribution depots throughout the UK.

The brewery was looking for a system that could import and calculate weekly key performance indicator (KPI) data against targets for multiple utilities including, but not limited to, gas, water and electricity, as well as analyse production data and calculate plant efficiency.

Carlsberg UK also required the ability to manage data imports from a range of meters to incorporate complex production procedures in place across the brewing process.

This had to be intuitive for access by non-technical users of the system.

Additionally, Carlsberg UK required an energy solution to distribute a range of use alarms and average usage alarms automatically via e-mail.

It needed a solution to display hourly dashboards at department operator level to monitor usage when the plant is running, stopped, shut down and during maintenance periods.

Carlsberg UK selected Esight to manage energy usage throughout the brewing process to enable it to monitor the efficiency of its brewing processes and optimise for best performance, therefore saving on bottom-line costs.

Activities such as generation of compressed air and excessive water usage required in the brewing industry are easily monitored and optimised using Esight.

Carlsberg UK uses Esight to monitor the plant for shutdown opportunities.

The system’s alarm module generates range and average alarms to be sent via e-mail to alert high usage in specific meters.

The alarms are linked to production allowing for early reaction and quick intervention times to process and reduce losses.

This can have a major impact on utilities costs, environmental compliance and production output.

The Esight system is managed by the Carlsberg UK on-site systems team.

The use of Esight is co-ordinated and facilitated to user departments by the energy centre manager and the water and effluent continuous improvement manager.

The brewery holds a weekly meeting with user departments to review Esight dashboards.

The weekly KPI data is calculated in Esight and compared with targets.

This allows for changes to be made to enhance productivity and therefore achieve energy savings.

Since implementing Esight, Carlsberg UK has achieved a number of energy saving goals.

These include: reduced overall energy consumption by 10 per cent; improved recovered waste energy from brewing process that uses 60 per cent of site usage; reduced site water consumption by 10 per cent; and reduced effluent cost by 16 per cent.

Reduction of overall energy usage was achieved by understanding consumption loads and matching with production periods.

Esight has enabled Carlsberg UK to utilise the CHP plant and recover heat by matching to process demands, which has improved recovered energy from the brewing process.

The Esight suite is used as a primary measure at the production level, focusing on software and plant improvements.

As a result, Carlsberg UK has experienced continuous improvement toward its root cause analysis.

The Esight Dashboard module enables the user to bring together essential energy information, charts or tables on a single page.

Users may run up to four easily interchangeable screens side by side, with each screen automatically updating every minute.

The Esight Dashboard has been designed to enable companies to show information on a full screen, suitable for display in receptions or in public locations.

Configuration is made simple through step-by-step screens; users are able to select the preferred layout.

Users may also choose how often the dashboard refreshes, which is key when monitoring real-time data.

Carlsberg UK uses the dashboard module to highlight areas of performance that are most important to them.

It utilises hourly dashboards at department operator level to monitor usage when the plant is running, stopped, shut down or during maintenance periods.
