National Grid achieved significant results in energy saving and emission reduction in the first quarter of 2011

In the first quarter of 2011, the State Grid Corporation of China conscientiously implemented the national deployment, further deepened the work on energy saving and emission reduction, accelerated the construction of UHV and smart grids, gave full play to the long-range inter-regional power grid to achieve mutual prosperity, optimized resource allocation in a wide range, and promoted energy saving and reduction. The advantage of platoons, increase cross-regional and inter-provincial power support, continue to carry out power generation rights trading, actively absorb clean energy such as hydropower, wind power, etc.; promote "two types and three new" lines to improve grid transmission capacity; carry out rural "low voltage" Comprehensive management, continuous improvement of power supply quality for rural power grids; launch of trials for energy-saving power generation dispatches to increase the utilization rate of clean energy and low-cost and high-efficiency units; strengthen the whole process management of power demand-side management projects, promote energy-saving and environmental protection technologies, and guide social energy-saving and emission reduction; implementation of contracts Energy management, speed up the construction of energy-saving service system, and comprehensively promote energy-saving emission reduction work, and achieved remarkable results.

In the first quarter, the national power grid line loss rate was 5.57%, with a production value of 0.2355 tons of standard coal per ten thousand yuan, and a value-added energy consumption of 0.9566 tons of standard coal per ten thousand yuan. The accumulative investment of 9.405 billion yuan in the management of rural "low voltage" has managed 8.399 million, accounting for 47.98% of the number of "low voltage" households. Efforts were made to absorb renewable energy. Wind power capacity on the grid reached 33.16 million kilowatts, an increase of 70.9% year-on-year. Wind power on-grid electricity reached 16.77 billion kwh, which was an increase of 66.1% year-on-year. Optimized dispatch, unified water-saving power generation increased 1.67 billion kwh. The increase in water use efficiency was 6.15%. The management of coal-fired unit de-escalation was strengthened, with 85.37 million tons of dioxide* emissions, a year-on-year decrease of 7.18%, and the CO2* emission performance of 0.64 grams/kWh, a year-on-year decrease of 16.88%. In the construction of power grid projects, 45,700 tons of Q420 high-strength steels were used to promote the reduction of steel consumption by 0.9 million tons, equivalent to a saving of 0.55 million tons of standard coal and a reduction of 20.1 tons of dioxide dioxide emissions. Completion of electricity generation right trading power of 8.128 billion kwh, equivalent to saving 657,300 tons of standard coal, carbon emission reductions 1,708,900 tons, * 21,900 tons of carbon dioxide. Promote 5.548 million square meters of heat pump applications, promote electric heat storage (cold) air conditioning 147,700 kilowatts, promote green lighting, high-efficiency motors, customer reactive power compensation devices and customer energy-saving transformers and other energy-saving environmental protection technology projects a total of 11,543, saving 497 million kilowatts Time.
