Reduce your annual capacity charges

Capacity charges make up ~1/4 of Western Australian business’ electricity bills. The annual charge is based on the previous year’s energy consumption during system peak demand intervals. Enel X helps you save on capacity charges by predicting when these intervals may occur, so you can reduce energy consumption at these times. Businesses either power down or switch to a backup power source, with little to no impact on operations. We currently work with 70 sites in Western Australia, and help them save up to hundreds of thousands of dollars on their energy bills each year.

How does it work?

Peak charge days

AEMO identifies the four days between 1 December and 31 March that experienced the highest system peak electricity demand. You’re then allocated an annual capacity charge that correlates with the median amount of energy you used during the 1.5 hour system peak periods on these days.

Calculation of charges

On each peak day, AEMO identifies the three half-hour trading intervals that had the highest demand for electricity, creating a pool of 12 intervals. The median demand of your business during those intervals gives your Median Peak Load value for the next capacity year.

Achieve bill savings

To manage and reduce your capacity charges, you need to reduce energy usage during these system peak intervals. You achieve savings by making temporary adjustments to equipment such as powering down pumps, chillers or compressors, or by switching from grid power to a backup generator or battery storage, with little to no impact to your operations.

Our leading technology has a high rate of accuracy in predicting when system peak demand intervals are likely to occur, allowing us to provide you with advance notice so that you can reduce your energy use accordingly.

Our technology leverages advanced machine learning algorithms and statistical models to identify system peaks which are driven by a number of variables including temperature, wind speed and climatic events such as bushfires and storms. It's been designed to target maximum capacity charge reduction potential while minimising dispatch frequency and quantities.

Our team provides daily week-ahead forecast emails that allow you to plan for potential peak days. We closely monitor demand and provide start and end times that are as close as possible to the peak periods to reduce unnecessary prolonged action taken by your business.

Our support team is available 24-7 to help you. If you don’t respond to our email or SMS notifications advising of potential peak days, we’ll give you a call to ensure your team is ready to respond.
