South Australia unveils new export limits for rooftop solar

South Australia’s electricity distributor SA Power Networks has announced plans to introduce new ‘flexible’ export limits for rooftop solar PV in some areas of the state in a bid to manage the growing amount of distributed energy resources and associated network congestion.

AGL partners with Finnish company to deliver C&I customers hybrid energy systems

Energy giant AGL has signed a memorandum of understanding with Finnish technology company Wärtsilä, to develop large-scale hybrid energy systems for AGL’s commercial and industrial customers.


Battery storage systems 30% cheaper than rival gas peaker plants for firming renewables

The contest is over. Faster, cheaper, more flexible than gas turbines … battery energy storage must be the future peaking energy service provider of choice says the hard evidence exposed in a new paper by the Clean Energy Council.


AEMC hands down final decision on cashflow rule change

The Australian Energy Market Commission has again rejected requests from transmission network operators TransGrid and ElectraNet to allow for a change of rules governing financing arrangements for large-scale transmission projects considered critical for Australia’s shift to 100% renewables.

ACT faces ‘substantial’ electricity bill increase, Evoenergy blames renewable energy targets

Evoenergy has blamed the Australian Capital Territory’s renewable energy targets for its proposed price hike, which would see average residential customers pay around 40% more for network charges, amounting to around $280 per year.

Researchers target rooftop solar in hunt for grid security

A new research project being led by the University of New South Wales will investigate how rooftop solar PV and other distributed energy resources (DER), including small-scale batteries can be best integrated into Australia’s power grid.


Clean energy technologies can provide grid security for less, study finds

New research shows renewables plus batteries would be able to offer Australia’s electricity grid the same energy security as coal and gas generators, leading to calls for regulatory changes.


AGL teams up with Ovo to digitise energy management in Australian households

AGL has announced a joint venture with the UK’s Ovo Energy for exclusive Australian rights to its Kaluza smart energy platform. The partnership comes at a time when grid stability is a hot topic and energy management systems are a key tool for owners of rooftop solar to optimise their investment.

Sunday read: The regulator’s wish is my export limitation

As distributed PV grows, new grid codes have scared installers across some markets. Network operators want to gain control over grid export, even of smaller arrays. Additions of new array controllers and special gateways could be costly putting speedy development of PV at risk. Fret not, says Fimer, as the Italy-based power-electronics manufacturer has placed the solution to the problem already inside its latest inverter range.


Solar export tax proposal stirs immediate outcry, but AEMC insists ‘doing nothing is not an option’

The Australian Energy Market Commission, Australia’s energy rule maker, today released its draft determination on how to integrate energy technologies like solar and batteries into the electricity grid. In the draft, the Commission revived its proposal for a solar tax, immediately stirring backlash.
