Guangdong pricing Bureau, provincial Commission under power supply conflict mitigation, this policy made necessary adjustments.
float price how to calculate
the policy provisions, fuel power plant generating peak period refers to from 8 o’clock every day, Internet power to fuel power plants within this period, with fuel price volatility by virtue of price mechanism. Fuel oil power plants power peak of the actual grid price = base price + floating price. Electricity pricing was formed by the local management of fuel power plants, to October 31, 2002, and the local price Bureau approved tariff as a benchmark price of various plants. Float price = (quarterly average fuel price-Datum price of fuel prices) x70%x power consumption.
quarterly average fuel prices by the provincial price Bureau in accordance with the quarterly average prices, announced at the Abendkleid end of each quarter. Electricity fuel consumption under situations there are 225 grams/kWh and 340 g/kWh it.
23 up next 8 o’clock Internet power is not floating
Internet power on oil power plants from 23 o’clock the day after 8 o’clock, its tariff not implemented with fuel prices float method, still perform original price (benchmark price). To fuel power plants are not subject to the power grid dispatching robbed the online power generation, electricity pricing approach that does not implement fuel price volatility. Floating method implementation from January 1, 2003. (Correspondent Chen Ying)

Currently, South grid has built of transmission lines road, only 220,000 v and the above of around Earth Equatorial embarked on a ring also more than enough; “Eleven-Five” South grid will new “two cross two straight” transmission channel, XD sent Guangdong will formation “eight cross five straight” main network frame sth sth
if said, past 3 years in the, South grid company created has was attention of “South network speed”, built has domestic structure most complex, and contact most close, and technology content highest of large grid, Today, standing in the “Eleven-Five” on the threshold of, China Southern power grid is seeking a new leap, greater development and new starting point.
the development of the major business
“15″ is the rapid rise of China Southern power grid. Data is boring, but it is the most telling: in September last year, the company has 15 months ahead nationally defined “15″ added 10 million-kilowatt target new power from West to East, in June this year of Tian-Guang fourth communication engineering production, from West to East, forming a “six-three straight” 9-500,000 volt channel, the current transmission capacity exceeding 12 million-kilowatt, is a 2000 10 times.
digital is specific of, can let you feeling to this copies changes of heavy: just five years within, South grid added 220,000 v and the above transmission line 22,111 km, variable electric capacity 89.531 million VA, had hit continuous 21 months average monthly built all grade transmission line more than 4,000 more km, and each 10 months new of all grade line to around Earth Equatorial a week of “South network speed”. China Southern power grid currently has more than 220,000-volt transmission line 45,449 km, variable capacitance 160.101 million VA, 2000 in both years twice times.
“we input on power grid construction, was the largest in history. “Party Secretary and Chairman of China Southern power grid company Yuan Maozhen said. 3 years, the China Southern power grid company total power grid construction investment of more than 80 billion dollars, this year alone to power from West to East and address grid “strangle hold” focused on engineering, arranged for power grid construction investment of $ 31.3 billion, 13 peak summer key projects all on time or ahead of production.
grid extraordinary development stems from the electricity supply situation in China Southern power grid company party group on scientific judgment. Is electricity supply difficulties in the year before last year, is an electricity supply more difficult year last year, this year is the most difficult year of electricity supply, the whole network tracking load reached 52.2 million-kilowatt, up 13.3% from last year, the largest electricity shortfall reached 9.4 million-kilowatt, per cent of national electricity shortfall of top one-fourth. Facing crippling power shortages, a company to assume more active social responsibility should focus on the power grid construction, solution to “strangle hold” problem, to minimize the impact of the economic and social power shortage at the very least.
look at the “Eleven-Five,” development of China Southern power grid company stand in a new starting point. South grid “Eleven-Five” power industrial development planning seminar Shang, parties representative and many expert full discussion Hou formation consensus, “Eleven-Five” during, XD East sent will new “two cross two straight” transmission channel, XD sent Guangdong formation “eight cross five straight” transmission large channel, to added to Guangdong transmission Abschlussballkleider 1150 to 13.5 million-kilowatt for Foundation carried out work, four province (area) formation strong of 500,000 v backbone network frame, South grid main network frame and Hainan networking, Hainan formation strong of 220,000 v grid.
self-innovation
southern power grid is the most complex, the associated most closely with, the highest scientific and technological content, but also runs the most difficult network concentrated on the current international advanced technology. Party Secretary and Chairman of China Southern power grid company Yuan Maozhen pointed out that the innovation capability of science and technology to a large extent reflects the southern power grid in the international and domestic competitiveness and influence.
in fact, the independent innovation of China Southern power grid company has already tasted the “sweet spot”. Known as “independent of the first” Guizhou-Guangdong secondary HVDC project, device independent of the rate of 70%. “Eleven-Five” period, China Southern power grid company ± 800,000 volts Yun-Guang HVDC transmission project planning and construction, transmission distance of about 1600-kilometer, planning of transmission capacity 5 million-kilowatt, device independent rate will reach more than 60% is planned for June 2009 unipolar before put into production.
research and application of ultra high voltage is a microcosm of independent innovation of China Southern power grid company. “Eleven-Five” period, China Southern power grid will challenge eight outstanding technical issues, AC-DC hybrid power system stabilization technology and DC transmission technology, ultra high voltage direct current transmission technology, networking with international power systems, submarine cables high altitude insulation technology, networking technology, distribution technology, power system operation management technology, and strive to make breakthroughs.
big development
in June this year, China Southern power grid company and Guangdong, Guizhou, and Yunnan Provincial Government separately signed a “Eleven-Five” Guizhou electric power transmission and Guangdong, cloud sent Guangdong framework, XD send Guangdong “Eleven-Five” will be released 1150~1350 million kW. By 2010, electricity from Guangdong will reach 2240~2440 million kilowatts, year transmission power is about 1160~1260 million kWh. With three signed framework agreements, companies within broader, higher level achieved five southern provinces (district) resource optimal allocation.
in fact, the State authorized to participate in the greater Mekong subregion regional power, as the concrete implementation of the cooperation unit, southern power grid company has achieved phasic results in many ways, and is gradually playing a leading role. Meanwhile, the company will also strengthen co-operation with the power of Hong Kong and Macao, and interaction between complementary on the electricity supply in Hong Kong, provide electricity support for Macao’s economic development.
