## Slide 10

## Analysis for April 2006:

**Analysis for April 2006:**
- Chillers increased consumption.

## HP Site Electrical Consumption Characterization

## Weekend equipments turn-off strategy

**Weekend average Site Power Electrical Consumption**

**Deviations to planned equipments turning off**

- Analysis:
-  Stabilized results.
-  Much effort for execution.
-  Strategy deployment recommended.

**Deviations type**

## 1

- Operational point on Nov, 2006.

- Expected operational point.

- 2

- 77 KVA x 2 = 144 KVA
- 77 KVA
- $ 70K

- On  April 30, 2007
- $62K/year lost

## Operational range for Oct 07.
