How are energy and emissions linked?

Most emissions come from the use of fossil fuels to generate energy. We want to work with our customers to reduce emissions by expanding the range of renewables and sustainable energy technologies without our energy ecosystem . You can do your bit by using electricity more efficiently and considering solar power for your home.

How can we better use energy to reduce emissions?

When many people switch on lights, air conditioning, TVs and start cooking, having showers and washing clothes simultaneously, this contributes to a significant spike in energy usage and what we call peak demand. When there is more demand for energy, emission levels may increase to generate more energy to supply the network.

Major spikes in demand for electricity occur during heat waves and cold snaps when we turn on appliances to cool or warm our homes.  If everybody reduces their use of appliances during peak times, less network infrastructure is needed, and that helps keep costs down.

Using energy more wisely will help reduce your energy bills and reduce your impact on the environment. Some basic tips:

  • set your air-conditioner to 24 to 25 degrees in summer, 18 degrees in winter
  • switch your hot water system to the Controlled Load 1 or 2 tariff and save money*
  • switch your pool pump to the Controlled Load 1 or 2 tariff*
  • use the BBQ instead of your oven or electric cooktop
  • turn off appliances at the power point

During summer, use fans instead of air conditioning, keep curtains or blinds closed and consider installing ceiling insulation.

In winter, close blinds and curtains, ensure your home is well insulated and set any thermostats to not higher than 18 to 21 degrees. Warm clothes and bedding are also a good environmentally friendly way to keep warm in winter.

When cooking; microwave ovens, electric frypans and pressure cookers are more energy-efficient than ovens. Think about turning fridges and freezers off if they won’t be needed for an extended period.

Front loading automatic washing machines use less water than top loading machines, and we should be hanging our clothes out to dry instead of using a dryer!

LED downlights are more energy-efficient than the old halogen downlights.

Our use of energy outside is also important. If you have a pool, a cover will help reduce heating costs, as will installing an energy-efficient pool pump.

*A Controlled Load tariff can be applied to a large electrical appliance such as a hot water system or a pool pump. The advantage to you is that you will save money, but your appliance will run only during off-peak hours. Controlled Load 1 is cheaper than Controlled Load 2, but electricity is available for longer on Controlled 2.

We have been working on some exciting sustainable energy initiatives

Our program to revolutionise the way off-peak electricity systems operate saw us install smart meters at 2,500 homes, delivering remarkable environmental and customer benefits.

The Off Peak Plus program improves network performance, can help save you money and speeds up the transition to a low-carbon future.

Smart meters help you integrate solar energy into your home and access demand management, including dynamically controlling your hot water system so it turns on during off-peak periods.

The program also provides us with real-time data to improve our response to outages, particularly during storms, giving you even safer and more reliable energy.

Other initiatives include the CoolSaver rewards programs for households with smart meters. With CoolSaver, we reward you for allowing us to reduce the energy consumption of your air conditioner during times of peak demand.

Our grid transformation projects help reduce emissions, and we are constantly working on new initiatives such as community batteries.

Supporting the transition to Electric Vehicles

Another initiative is a partnership to provide electric vehicle charging stations at 1,000 of our transformer substations. We are also participating in an electric bus charging trial. You can learn more about electric vehicles here .
