The Australian Energy Regulator (AER) has approved CitiPower and Powercor’s investment plans, the centrepiece of which is a major program to boost rooftop solar, batteries and electric vehicle (EV) adoption.

The AER handed down its final determination on the networks’ investment plans for the 2021-2026 period, with the Future Networks program being one of the most critical initiatives approved by the determination. 

It incorporates a dedicated solar enablement initiative and the expansion of the networks’ digital capabilities to facilitate a variety of choices for customers.

CitiPower and Powercor General Manager, Electricity Networks, Mark Clarke, said the program will support customers to connect more solar, batteries and EVs, lower their power bills and reduce their environmental footprint.

“The energy market is changing rapidly, and we are developing the network and our systems to enable this,” Mr Clarke said.

“Our investments will ensure 85 per cent of solar customers are able to export into our network 85 per cent of the time.

“We will also develop the network to allow electric vehicles to be charged and eventually be another source of exports. 

“The announcement this week that the Victorian Government will incentivise people to buy electric vehicles underlines the importance of these investments.”

On average in 2021, 70 customers have connected rooftop solar in the Powercor network every day, bringing the total number of households with solar to 155,000 – or 20 per cent of Powercor customers.

Forecasts for the next five years predict that the number of Powercor customers with solar will increase to more than 30 per cent. 

In CitiPower, almost 500 new residential rooftop solar systems were connected in the first quarter of 2021. This brings the total number of households with solar in CitiPower to almost 15,000 with this number expected to increase significantly over the next five years.

The digital program will prepare the network for more distributed energy resources (DER), including demand management initiatives that support customers’ energy efficiency and emerging virtual power plant projects and community level batteries.

“We are building sophisticated systems internally to make sure all forms of DER are supported by our network while we also maintain power reliability and quality for all customers,” Mr Clarke said.

The solar enablement program will use traditional approaches such as capital upgrades as well as technology such as a dynamic voltage management system to facilitate more solar and exports.

This follows the success of the Solar Hotspots program announced in March 2021 to alleviate capacity constraints in areas with some of the highest solar penetration across the Powercor network.

More than 70 per cent of the fieldwork is complete, and is expected to realise benefits for more than 50,000 solar customers in nine targeted regions by June 2021.

As regulated businesses, CitiPower and Powercor’s proposed investments, pricing plans and rate of return are approved by the AER every five years and this determines the revenue able to be recovered from customers.
