With large consumers of energy feeling the pinch the most, they are now taking matters into their own hands and exploring alternative options to better manage these costs.
Here are four key actions large consumers of energy can explore to put pressure on their costs:
Entering a PPA can help reduce costs, at least for a period of time, but it can have its drawbacks in terms of increased complexity and risk exposure. There are many different forms and variants of a PPA, each with their own unique advantages and disadvantages. See the chart below for a summary and the key considerations.
In the right location and under the right circumstances, self-generation behind the meter can become one of the most attractive options. However, it also comes with a whole range of complexities that need to be carefully considered before you embark.
Given most self-generation options are solar and they can be highly variable in output. The easiest form of ‘firming’ solar is to procure electricity from the market. Firming behind the meter is becoming increasingly feasible by using batteries (that are well suited to short term applications) and reciprocating engines (for larger firming requirements).
Where available, firming with demand response opportunities can be the most attractive option, but is highly situation specific. Many possible opportunities exist ranging from better management of buildings to finding sources of variable load such as large pumps or even utilising existing generation options in the form of back-up generators.
There is no doubt Australia is amidst a major energy transformation which at times will be messy and complex. While I feel Australia is on the right pathway, there are still some tough decisions by Government to be made. In the interim, if large consumers of energy can make small yet smart tweaks, these may at least provide some relief.
