Since it had already been established that Demand Management would be the only energy management opportunity that would be considered, a ‘Walkthrough’ energy audit was conducted. During the energy audit the following non-critical loads that could be controlled, were identified.
• Energy we have; the challenge is the power.

• Proper demand management can positively impact on your electricity bill.
