Japan has launched a subsidy programme to support the installation of lithium-ion battery-based stationary storage systems, offering to pay individuals and entities up to two-thirds of their purchase price.

Japan’s Ministry of Economy, Trade and Industry (METI) announced the opening of the application process for subsidies on Monday and said a budget of ¥10 billion (US$98.3 million) had been earmarked for the programme.

Subsidy payouts will be capped at ¥1 million (US$9,846)  for individuals and at ¥100 million (US$982,000) for businesses, available for the installation of battery systems of 1kWh capacity or more. Systems must also be assessed and receive technical accreditation through the country’s Sustainable Open Innovation Inititative

The ministry outlined the reasons for launching the scheme, reiterating Japan’s acute energy problems since the 2011 earthquake, tsunami and Fukushima nuclear accident, the anniversary of which was marked last week.

There is a multitude of possible applications for stationary storage. According to METI, like many other nations and regions, Japan is interested in looking at how the integration of renewable energy sources can be aided by using storage, managing peak supply and demand and stabilising power supply.

The Japanese government, through METI, is keen to measure what effect mass production will have on battery prices and to what extent battery storage could aid energy self-sufficiency.

Japan joins Germany in offering direct subsidies for energy storage systems. Germany now offers subsidies for residential PV-plus-storage systems, although according to industry figures uptake on the programme has been limited.

Growth in the embryonic battery storage industry has been stimulated by differing drivers in different regions, with some regions such as California and Puerto Rico using mandates to compel utilities or renewable energy project developers to deploy storage.

Energy storage with batteries for PV is covered extensively in ‘Put up or shut up time for storage’, in the latest volume of Solar Business Focus, available now.

    Looking back, 2014 was a year of convalescence for a PV industry still battered and bruised from a period of ferocious competition. End-market demand continued apace, with analysts towards the end of 2014 predicting the year would see between around 45 and 50GW of deployment. That has begun to feed through to the supplier end of the market, with all the main manufacturers announcing capacity expansions in 2015 and further ahead.

    Although the past few years have proved extremely testing for PV equipment manufacturers, falling module prices have driven solar end-market demand to previously unseen levels. That demand is now starting to be felt by manufacturers, to the extent that leading companies are starting to talk about serious capacity expansions later this year and into 2015. This means that the next 12 months will be a critical period if companies throughout the supply chain are to take full advantage of the PV industry’s next growth phase.
