One of the first large-scale solar farms in Japan so far to be equipped with battery storage in order to meet the requirements of a local grid operator and utility, has been completed on the island of Hokkaido.
Q CELLS has officially launched a home solution that promises a “100% sustainable power supply,” through combining solar and battery storage to meet the majority of demand and a digital cloud solution to cover the rest.
It has always been anticipated that by the early 2020s, the feed-in tariff would have tapered away in Japan’s booming solar market. Andy Colthorpe speaks with analyst Izumi Kaizuka at RTS Corporation to learn more about what the future holds for post-subsidy solar in Japan.
The UK government has confirmed that energy storage systems will be eligible under the UK’s newly unveiled successor policy aimed at supporting the deployment of residential solar in the wake of feed-in tariff cuts, but only if co-located with a participating renewable energy generator.
The UK will need 20 million ‘mini power stations’ to reach its net zero energy goals, with the need to create a policy framework for technologies like solar PV and energy storage an immediate priority, a group convened in Britain’s parliament this week heard.
Details have emerged of the UK's Smart Export Guarantee (SEG), which will see owners of small-scale solar facilities continue to be paid for surplus energy sent to the grid, aiming to close the policy gap left by the end of feed-in tariffs (FiTs), by the end of 2019.
Walking around Energy Storage Europe this year it was obvious that the show, like the market, has grown from a small handful of “strong believers” as one source put it, to a forward-looking show focused on a ‘business-as-usual’ scenario.
Sales of battery storage units to residential households in Germany are booming, but it’s the value of services the batteries can provide, rather than the hardware itself that offers a long-term economic opportunity, a Siemens representative has said.
Residential PV system owners who signed up to Japan’s feed-in tariff policy for 10-year contracts, that will soon expire, may be able to find new ways to benefit from their solar using battery storage.
The rise of grid trading and off-peak tariffs, rather than the closure of the feed-in tariff and potentially the export tariff, will see the domestic storage market experience “huge growth” over 2019 according to SolaX’s European product manager ahead of next week’s Solar & Storage Live conference and exhibition in England.
UK energy regulator Ofgem has published guidance outlining how developers and asset owners can add storage to their subsidised solar installations without losing accreditation to the Renewables Obligation (RO) and Feed-in Tariff (FiT).
A 250-home ‘virtual big battery’ was switched on in Canberra, Australia last week, allowing residents to sell solar-generated power at a significantly higher price than available to them through feed-in tariff (FiT) policies.
UK gas and electricity market regulator Ofgem has made a “game changer” decision for UK energy storage, by confirming that solar farms are able to retain accreditation under the government Renewables Obligation (RO) when supplying electricity to batteries.
UPDATED: The Queensland government plans to remove the premium feed-in tariff (FiT) from PV consumers on its Solar Bonus Scheme who install energy storage batteries.
While parallels are often drawn between the solar and storage industries, financing energy storage projects is a lot more complex than simply “transposing” learnings from solar to batteries.
A renewable energy auction which could take Australia’s capital Canberra over the line in meeting a long-term “90% renewables” target will also lead to the deployment of 5,000 residential and commercial battery storage systems.
A spokesman for Solar Frontier has said that a retrofit market for up to half a million home energy storage systems could open up in Japan from the year 2019, as agreements made under a subsidy scheme for solar in existence before the current feed-in tariff begin to reach the end of their terms.
Volker Wachenfeld of SMA explores some technical and policy factors driving growing use cases for refurbishing home PV systems to add energy storage, and the markets where this is already gaining traction as an idea.
Top names have signed up to support the Energy Storage division of PV Tech Storage’s publisher Solar Media, which has launched a series of events and media activities for next year, targeting the UK’s nascent industry.
