2, growth rate presents the trend slowed down year by year, wherein each region CO of 2014-2020
2discharge about 1,815 hundred ten thousand tons, 2021-2025 about 2196.7 hundred ten thousand tons, 2026-2030 about 2196.72 hundred ten thousand tons, growth rate constantly slows down.
As can be seen from Figure 7, subregion is seen, except the area discharge of west, Henan increase always relatively steadily except, other area alignment all progressively slow down, and peace crane Pu area speedup fall is maximum.
On basis based on existing comprehensive resources strategic planning model, point is pasted for Henan Province's economic society and endowment of resources, by setting up multizone Henan Province comprehensive resources strategic planning model (HNIRSP) considering transregional transmission of electricity, research realizes the global optimization of each department, Henan resource.Under Henan Province's electric integrated MRP electric power layout situation, 2014-2030 the whole province needs the total demand of newly-increased installation to be 13,300 ten thousand kilowatts, after removing EPP, the whole province increases installation demand newly and is about 9,695 ten thousand kilowatts, installs compared with spatial balance result with the whole province, reduces installed capacity 3,225 ten thousand kilowatts, directly can reduce whole society's investment about 108.6 hundred million yuan, reducing emission of carbon dioxide about 11,627 ten thousand tons, reducing emission of sulfur dioxide about 37.7 ten thousand tons, reduces discharging oxides of nitrogen about 32.8 ten thousand tons.
Between the 2014-2030 of Henan, normal power supplies and EPP gross investment are about 2279.23 hundred million yuan, and average annual growth about 6.21%, speedup presents the trend progressively slowed down.Subregion, because future electrical energy demand increases fast in the Middle East, Henan and southeast, Henan.Affect by power supply architecture, the thermoelectricity installation of following the whole province still will account for larger specific gravity, and the proportion of wind-powered electricity generation, photovoltaic, energy efficiency power plant will be developed rapidly after the year two thousand twenty.Henan end of term the year two thousand thirty thermoelectricity installation will be about 97618MW, account for 70.28% of total installed capacity; Wind-powered electricity generation, sun power the year two thousand thirty will become second largest conventional electric power source, Henan, and end of term installation is about 30086MW, accounts for 21.66% of total installed capacity.Send a telegram here outside, under the trend of clean energy resource and energy efficiency power plant steady-state growth, Henan progressively adjusts the situation relying on thermoelectricity, and its power supply architecture will more be tending towards reasonable.As the energy efficiency power plant resource of dsm important supplement, all kinds of EPP will reach 38678MW Henan the year two thousand thirty, wherein all kinds of EPP that will provide more than 24712MW of Yu Xi, the Middle East, Henan and southeast, Henan.
During the installation in future of southeast, Henan is formed, will be main based on green power supply, send a telegram here outside district, wind-powered electricity generation, photovoltaic, energy efficiency power plant and province's inner region transmission of electricity will become the main source that this region electric power supports.Due to the whole province's resource and demand contrary distribution, power generation configuration restricts by resource situation, and the unbalanced needs of power generation configuration, by building electrical network, transport the quantity of electricity vacancy making up each department by interregional electric power.Along with trend more obvious of regional imbalance, the each interregional electricity in Henan exchanges and presents ascendant trend, adds up to and exchanges electricity 5361.8 hundred million kilowatt hour, increase by 17.23% every year between 2014-2030, growth rate strengthens year by year, and mainly in district, 6 large regions send the direct conveying between receiving end.
Along with the development of green electric power supply, the whole province CO
2reduce discharging intensity to reduce year by year, underspeed and increase year by year.From CO
2emission behaviour is seen, the utilization of outer incoming call, wind-powered electricity generation, photovoltaic generation and EPP resource, substitutes fossil energy Be very effective, adds up to discharge 5,865 1,000,000 tons of CO between 2014-2030
2, growth rate presents the trend slowed down year by year.
