Grids & Integration

Investment in large-scale solar appears to be faltering in Australia. The technology with the lowest cost, with no emissions and the fastest time to delivery, has often found itself dangling at the oversubscribed end of a limp transmission line, with additional, expensive requirements to connect, or earnings-slashing curtailments when operational. Investors have found no reassurance in the federal government’s winking at coal, courting of gas, and undermining of agencies established to support innovation and investment in renewables. In short, the Australian prime minister is showing a complete lack of urgency to act on climate change. Enter the Renewable Energy Zone.

Ikea Adelaide is leading the way for the Swedish giant’s global aspirations towards 100% renewable energy through what is being touted as Australia’s largest grid-connected commercial microgrid. The two stage project boasts a range of unique features which could lay the foundations for a new sustainable energy model for Australia.

A 50/50 joint venture between Clough Group and Spanish infrastructure giant Elecnor has been selected as EPC for the 700km NSW section of the SA-NSW Interconnector, Project Energy Connect. The big jobs require the big guns, and it seems as though the big guns have been called in on this occasion, with Project Energy Connect deemed integral to the energy future of both states.

The Western Australian Government’s Energy Transformation Taskforce has revealed its first blueprint for the isolated state’s energy system transformation over the next two decades. The blueprint, which features four separate models, sees rooftop solar and accompanying battery storage excel in the coming years, although it suggests coal-fired power will still have a large presence.

One of the few benefits of COVID-19 is the ability to virtually attend conferences that may previously have been a plane ticket too far. Tomorrow’s South Australian Renewable Energy Conference is a window of opportunity …

Australia needs more transmission and network capacity to efficiently use its vast, distributed renewable-energy resources, and to enable transition to a low-cost, zero-carbon electricity supply. In the Australian Opposition’s Budget in Reply it aims to make Australia’s inherent wealth work better for the nation, and puts transmission infrastructure upgrade at the centre of the country’s recovery from Covid-19.

Singapore-based solar plus storage microgrid expert Canopy Power has helped the Batu Batu resort on Malaysia’s Tengah Island reduce its dependence on diesel fuel through the installation of an integrated system which will cover a quarter of its energy needs.

Powerlink Queensland has launched its ‘system strength as a service’ model in Far North Queensland through a deal with renewable energy giant Neoen’s 157 MW Kaban Green Power Hub. Powerlink Queensland’s model is to install a large synchronous condenser and then on-sell its system strength capacity to multiple renewable energy projects, a way to increase renewable energy integration into congested parts of the grid.

Solar and energy storage play an essential role in Project Gilghi, an off-grid water security innovation that has the potential to help a great many Australians, particularly Indigenous Australians, and people around the world who are struggling with poor access to potable water and sanitation.

As some parts of Australia’s distribution networks threaten to blackout under the flow of rooftop solar exports, ARENA announces funding for a trial that will enable flexible exports in line with what the networks can bear. Smart software is the answer.
