Genesis Energy To Offer Residential Customers Variable Rates

Genesis Energy is due to offer their residential customers the option to pay different prices for electricity at periods of high and low demand, instead of a single flat rate 24 hours a day.
Spokesperson Richard Gordon says that they have installed 200,000 Smart Meters that have the ability to measure electricity consumption at half hourly intervals, and have a team in place working on differentiated tariffs.
Genesis Energy customers will still have the option to pay a flat rate if they prefer and the variable pricing won’t be available to all customers until they install another 300,000 smart meters.
Contact Energy have announced recently that they would install the new meters to 150,000 North Island customers, having already rolled out 60,000 in Christchurch.
They are already offering the variable rates to some Christchurch customers but it will be two or three years until the time of day tariffs are available elsewhere.
The variable pricing could have a knock on affect for the environment, reducing the need for new power stations and relieving the strain on the national grid.
Research suggests that time of day tariffs could cut peak demand by 5 per cent, while allowing retailers to charge high rates at short notice to counter spikes in demand could cut peak demand by up to 20 per cent.
One complication is that some electricity meters are owned by retailers, some by consumers and others by lines companies, and there is no consensus either on who should be in charge of the change to smart meters or the technology they should be investing in.
A third of the 1.8 million electricity meters in New Zealand have already been upgraded to the new technology, but Jan Wright of the Paliamentary Commission for the Environment argues that lines companies are the natural custodians partly because they have an incentive to sell people electricity.
“If I were to wipe the slate clean and start again, I think what I would like to see would be the ownership of the meters in the hands of lines companies because they have an in-built incentive to keep peak power down, retailers hardly have it at all. To me the interests of households the environment and lines companies are pretty much aligned here.”
She says retailers are expecting to sell metering data to lines companies and if they can’t settle upon a price, there is the risk of lines companies installing their own secondary smart meters just to get the information they need. This is already happening in the Waikato.
Genesis state that they are committed to ensuring customers can access data information on their electricity consumption and advise that they are not in favour of allowing monopolies to have control of this.
TrustPower spokesman Graeme Purches is a smart meter sceptic and believes that retailers are already running up unexpected costs. Some are investing in smart metering as a way of getting rid of the manual meter readers, but in practice it has proved difficult to remotely communicate with the meters without interruptions he says.
