Utility Scale Storage

In the UK investor’s first deal since entering the Australian marketplace, Octopus Investments and Australian renewables developer Edify Energy have arranged more than $450 million to finance one of Australia’s major PV projects – a 333MW DC (275MW AC) solar farm, which has an approval to be collocated with a 100 MWh energy storage facility at Darlington Point, NSW.

After releasing the December quarter update for the 50 MW Kidston Solar Project Stage 1, which showed strong revenues and a big boost in generated power, Sydney-based Genex Power has shared a research paper on the term sheet signed with electricity provider EnergyAustralia for the 250 MW Kidston Stage 2 Pumped Hydro Storage development.

In the final days of 2018, the NSW government gave its tick of approval for the construction of the state’s largest solar farm to date. The approval rounded off a year that saw a flurry of utility-scale solar construction activity and an unprecedented number of big solar additions in the state.

NREL has released an report which, for the first time, highlights utility scale energy storage costs with various methods of tying it to solar power: co-located or not, and DC- vs AC-coupled.

Sydney-based publicly listed Genex Power has signed an agreement with electricity provider EnergyAustralia to begin construction on the 250 MW pumped hydro project as part of the Kidston renewables hub in north Queensland. Genex is now looking to secure financing for a 270 MW solar component of the project.

The New South Wales Department of Planning and Environment has given the green light to a massive solar farm coupled with a utility-scale energy storage facility. The project proposed by Edify Energy is valued at $407 million.

The New South Wales government has launched its ambitious pumped hydro roadmap designed to back the rising level of wind and solar in the energy mix. Meanwhile, the board of government-owned energy provider Snowy Hydro has given the green light to its landmark $4 billion pumped hydro expansion project, Snowy 2.0.

The system turns light of white-glowing molten silicon into electricity using specialized PV cells. The researchers claim that the concept could store electricity at around half the costs of pumped hydro. A single system comprising two ten meter tanks could power 100,000 households.

Hydrogen holds promise for harnessing renewables to produce clean fuel for transport, grow a green energy-export industry, and overcome seasonal intermittency challenges in the grid. On the road to viable hydrogen production every cost-efficiency measure counts.

While little action is seen on the federal level, energy storage is increasingly coming to the fore as part of state and territory energy policies. With a rising number of residential battery subsidy schemes taking shape in Australia, funding appears to be slowly moving away from solar to energy storage. Such initiatives are poised to not only reshape the battery storage market, but also have a major impact on the grid, making it more reliable, responsive, and flexible.
