1. Capacity Charges

The cost of electricity is determined more by when you use it, rather than how much you consume. Capacity charges generally amount to around 20 to 30% of electricity charges. Significant users may find it viable to reduce or even eliminate this charge by making minor changes to their usage pattern. These savings come as a reward for not contributing to the need to build extra capacity to service only very small number of hours of network annual peak demand time.

2. LED

LED lights typically result in savings of more than 50% compared to fluorescent lights, or 75% compared to high bay lights. That makes for a very quick payback.

Due to their longer life, replacement costs are reduced. They also emit less heat.

3. Batteries / Hybrid Power

A generator and batteries can be added to solar to ensure continuity of supply, or provide power where you don’t have access to the grid.

We’ve implemented combination battery/generator systems in areas where continuity of supply caused operational problems. 

Currently we don’t see a business case for installing batteries for the sole purpose of reducing grid consumption as they are too expensive to provide the required return.  

4. Power Upgrades

Anything that reduces your draw from the grid may eliminate the need for costly upgrades. Draw from the grid can be reduced by any of the following:

• Solar
• Batteries
• Generator
• Power factor correction

5. Power Factor Correction

Power factor correction relates to impedance. In certain situations, up to 25% of electricity coming in is wasted. Correcting that issue can be simple and carry a big payback.

6. Gas Tariff Negotiations

7. Wind Power

On an individual site basis, other than powering lights, we can’t at this stage see a significant benefit being available from wind power.
