Update Nov 01, 2014

The Japanese government has confirmed that it will review the current feed-in tariff programme for solar and wind at the end of the year, due in part to fears over lack of available grid connection and a bottleneck of large-scale projects.

Kazuya Aoyama, a spokesman for the renewable energy division of Japan’s Ministry of Economy, Trade and Industry (METI), told PV Tech that METI will form a working group to discuss, and hopefully combat, the nation’s problems with grid connections for solar and wind projects. The decisions had been made at a meeting on renewable energy held at the ministry on 30 September, Aoyama said by telephone.

Japanese newspaper Yomiuri reported that METI was considering changing rules so that developers and facility owners would only receive the FiT at the rate applicable when projects are connected to the grid, as there have been claims some developers delay the start of projects to maximize profits. It is thought, however that the actual number of such projects is fairly small, with most other projects delayed for other reasons such as the difficulty of obtaining grid connection.

Update Apr 01, 2014

New FiTs were announced and confirmed for April 1 2014. The country’s Ministry of Economy, Trade and Industry defines residential solar as anything under 10kW in capacity and commercial solar as anything above that. Non-residential FiTs will be paid over 20 years, with residential FiTs lasting half of that duration.

Update Feb 01, 2014

The Japanese Ministry of Economy, Trade & Industry (METI) has given a temporary reprieve to developers of 748 solar projects located within the country that have gained approval on receiving feed-in tariffs (FiTs) but have yet to be built.

After a METI survey conducted in October 2013 revealed that all of these 740+ solar projects do not have either land or equipment deals in place, the ministry has now ruled that the developers of these facilities now have until either March or August to acquire paperwork regarding to property and equipment agreements.

The METI survey was spurred on by the news that only 10% of approved PV facilities in Japan had actually been built.

According to Munehiro Nakagawa, spokesman for METI’s renewable energy and new energy technologies division, hearings will be held for companies and developers that have yet to secure paperwork regarding both property and equipment deals by the end of March. The hearings will likely revolve around the possibility of revoking FiT eligibility for those specific projects.

On the other hand, projects that have at least acquired paperwork regarding land agreements but not equipment accreditation, or vice versa, have until the end of August to gain both documents. If the developers have not obtained all the necessary paperwork by 31 August, they will also be called into hearings by the METI, with the revoking of FiTs once again being the likely outcome of the inquest.

Update Apr 01, 2013

Japan’s government has rubber-stamped an expected cut to the country’s solar feed-in tariff.

The cut, suggested by an advisory panel last month, came into effect on 1 April and will see Japan’s FiT cut by 10%.

This means the previous rate of ¥42 (US$0.45) will fall to ¥37.8.

Industry players in Japan have told PV-Tech that the cut would not harm Japan’s booming solar industry as even the lower rate represents a substantially higher FiT than that offered in other key markets such as Germany and China.

Recent figures revealed that Japan's PV installation rates increased by nearly 150% in the last quarter of 2012.

Update Mar 01, 2013

A 10% cut in the country's solar feed-in tariff will be set from 1 April 2013 by the Japanese government. A rapid growth has been noticed in Japan’s solar market, with the sales of solar panels to tap a rise by over 150% in the fourth quarter of 2012.

Update Jan 01, 2013

The Japanese Ministry of Economy has announced that Japan installed 1,398MW since April 2012. A comission examines the possibility to reduce the Japanese current feed-in tariff for PV installations. However, the current rate of ¥42 (US$0.51) per kWh will end with the closing fiscal year.

Update Jul 01, 2012

Japan published its renewable energy road map, which curiously included the country’s plans to commission 14 nuclear plants by 2030 whilst concurrently expanding its feed-in tariff systems for renewables as well as increasing support for R & D projects and local revitalization.

Independent commission, the Fukushima Nuclear Accident Independent Investigation Commission (NAIIC), presented a report to the National Diet of Japan concluding that the accident at the Fukushima Daiichi nuclear power plant a “profoundly man-made disaster”.

Update Jun 01, 2012

METI finally issued the Ministerial Ordinances for the new feed-in tariffs. An increase by 1.2% is planning for the household electricity bills, which is an additional ¥87 (USD$1.10) monthly..

The scheme requires Japanese utilities to buy electricity from renewable sources at a rate of ¥42 (US$0.51) for systems of 10kW or more for up to 20 years. This is double the tariff offered in Germany and more than three times that paid in China, reports Reuters.

The Japanese government approved plans to restart units 3 and 4 of the Ohi nuclear power station (NPS), western Japan, overseen by Kansai Electric Power Co.The plan is to raise the energy independence ratio to 70% (self-sufficiency energy plus self-developed energy supply, divided by total primary energy sources).

Update May 01, 2012

Jefferies has lauded the Japanese decision to omit net-metering purchase prices from the new feed-in tariffs. The new tariffs include residential facilities of less than 10kW at ¥42/kWh (US$0.4505/kWh),while hybrid systems will receive ¥34/kWh (US$0.3647).

Update Apr 01, 2012

A Japanese government panel is said to be on its way to setting a feed-in tariff of ¥42 per kilowatt hour (approximately US$0.51), according to a Reuters report

On April 25, the 6th Purchase Price Calculation Committee for the new FiT program set out new guidelines, effective July 2012:

1. up to 10kW = US$0.506/kWh, for 20 years, excluding tax

2. <10 kW PV systems: US$0.5323/kWh, for 10 years, including tax, with a seperate FIT for any surplus power generated.

Details have not yet been released, however an official announcement will be issued by the end of May.

Update Mar 01, 2012

Prime Minister Naoto Kan was forced from office following criticism of his handling of last year’s earthquake, tsunami and its nuclear disaster in Fukishima, but not before rushing through a renewable energy bill, effective July 2012.

Bloomberg New Energy Finance has estimated that under Japan’s proposed tariffs, solar and wind projects could achieve equity returns as high as 44% and 51%, respectively, with total investments reaching up to US$37.5bn over the next three years. The market research firm predicts over 10GW of new solar projects installed by 2014, requiring investments of US$12.5bn/yr over the next three years. Bloomberg New Energy Finance states Japan could become the third largest solar market in the world by 2014.

The bill will introduce opportunities for independent power producers to buy electricity from solar, wind, biomass, small-scale hydro and geothermal power for 15 years. Prices for wind, small-sized hydro, biomass, geothermal will be either US$0.19kWh or US$0.24kwh.

There will be no difference in surcharges from one company to another as power producers will pass their total payments to users evenly nationwide.

Update Jan 01, 2009

Back in 2008 Japan announced funding of 9 billion yen (US$94.2178) to go towards the encouragement of installing solar power systems on over 70% of new houses.

Back in early 2009 Energy Matters reported that Japan was due to take on more renewable energy sources in a bid to stimulate the falgging economy. This inititaive encourageed the introduction of the FiT rate which can be seen in the above table.

To achieve the target, a number of renewable-energy-related measures have been adopted: a requirement that large commercial buildings formulate CO2 reduction plans; installations of solar PV on government buildings and schools; subsidies for household solar PV; promotion of green-power certificate trading and purchases; use of city building rooftops for private renewable energy installations; and implementation of city-owned renewable energy projects that are financed by businesses and citizen-investors.
