Brewing - energy

Electricity costs

Costs of pumping water depend on water volume and pressure drop supplied

• measure power consumption, flow and run hours
• enables improvements to be measured

Audit water usage

Do you have cold radiators in a tank room?

• they will need defrosting. Use off-peak electricity (not water sprays).

Compressed air may take up as much as 10% of a brewery’s electricity usage.

Audit regularly for leaks

• leaks may account for a large part of compressed air usage otherwise
• there may be an opportunity to measure leakage by measuring compressor output when plant is “quiet”
• ultrasonic air leak detection is available

Consider air flow meters on large compressed air users

• for example packaging plant

Triad managment

• reduced rates in exchange for large load reduction on request
• e.g. Shut down primary refrigeration plant
• will be for short time so no harm to beer quality
