Grid restrictions slowing Japan's solar revolution 09 OCTOBER 2014 APPLICATIONS & INSTALLATIONS, FINANCIAL & LEGAL AFFAIRS, GLOBAL PV MARKETS, INDUSTRY & SUPPLIERS, MARKETS & TRENDS, TOP NEWS BY: IAN CLOVER Tokyo skyline.Power-hungry Japan has turned increasingly to solar power to feed its grid, but utilities have begun to restrict PV's access.wikimedia commons Speed of PV's expansion placing strain on grid's capacity to absorb solar-powered electricity, prompting five utilities to restrict grid access of new solar farms.
Despite having grown by more than 7 GW in 2013 and on course to top 8 GW of new capacity this year, Japan's solar revolution could be derailed as leading utilities begin suspending grid applications for new solar projects. The Japanese solar sector, worth close to $30 billion in 2013, has enjoyed vast public and political support as the go-to alternative to nuclear power in the wake of the 2011 Fukushima Disaster. Yet late last month five of the country's leading utilities began restricting access of new solar plants to their grids, blaming the near-constant expansion of the energy source over the past two years – coupled with the fact that it only delivers to the grid when the sun shines – for causing connection problems. "Because the transmission lines in some parts of Japan are very limited, solar is causing a problem in some places," Izumi Kaizuka, manager of the research division of RTS Corporation, told pv magazine. "We anticipated this problem last year, and luckily the Japanese government has begun a committee set up to investigate the issue. It will announce how it will tackle the problem at the end of year." There are numerous options open to Japan, with transmission expansion the most likely route, says Kaizuka. "Each utility wants to hold back some extra transmission capacity for nuclear power, even though there are currently no nuclear plants in operation in Japan." Kaizuka believes, however, that "one or two" nuclear power plants will restart operation – maybe not as early as next year, but possibly by 2016. "Looking at Japan's solar market right now, we anticipate further growth for the remainder of the year, and next year as well. But after that, the market will begin to shrink." The actions of Kyushu Electric Power Co.; Shikoku Electric Power Co.; Tohoku Electric Power Co.; Hokkaido Electric Power Co., and Okinawa Electric Power Co. in curtailing grid access for new solar projects could well be the beginning of the end for Japan's large-scale solar revolution. Writing on the Japan Renewable Energy Foundation (JREF) website, JREF director Mika Ohbayashi revealed that Kyushu has put negotiations for grid access on hold "for several months" while the utility reviewed all access requests. Currently, total demand for grid connection would amount to 12.6 GW if all was approved, Kyushu said. The utility's minimum daytime demand is just 8 GW, but JREF believe that Kyushu's sudden action to suspend access is "unreasonable". "Depite more than 12 GW of capacity that has started the negotiation on grid connection so far, we only see a little more than 3 GW of variable renewable power sources actually in place," Ohbayashi wrote. "Under such circumstances, the abrupt withholding of responses is unreasonable in the ordinary business sense, and will bring great confusion to the renewable energy business." As solar projects pile up – partly due to deliberate developer delays first investigated by METI earlier this year – the bottleneck could usher wind power to the front of the energy queue. Solar's rival, wind power has only grown by around 1.7 GW since July 2012, but the government is keen to increase its share in the energy mix, according to government sources. |
