Emerging energy is developed to renewable energy or theoretically inexhaustible energy source, with high environmental benefits. Because the energy density of the new energy is small, or low-grade, or intermittent, according to the existing technical conditions of conversion of the economy is still poor, still in the research, development phase, can only be developed and used in accordance with local conditions, but most of the new energy is renewable. Rich in resources, wide distribution, is one of the main energy in the future.
May 22, the director of the National Development and Reform Commission introduced, to encourage and guide the introduction of the details of China's investment in the near future. National Energy Agency official website Bulletin, in order to implement the "new 36", the National Energy Bureau is studying the development of incentives to guide private investment in the field of implementation of the rules, is expected to be introduced by the end of June.
The state Energy Bureau said that the implementation rules support private investment in all areas of new and renewable energy, and establish an open and transparent project development rights mechanism to ensure that private enterprises have equal access to project development rights, in equipment manufacturing, industrial system construction, distributed energy development, To explore the international market and other aspects of concrete support measures.
At present, the private investment in small hydro, biomass energy, solar thermal utilization, as well as solar cells, crystal silicon, wind power equipment manufacturing and other fields in the dominant position. In particular, wind power installed accounted for 15% of the country, wind power equipment capacity accounted for half of the country.
The National Energy Agency estimates that the total amount of private investment in new and renewable energy sectors has exceeded 800 billion trillion, generating capacity of more than 49 Million-kilowatt, accounting for the country's new and renewable energy total installed capacity of 18%.
From the distribution of investment, private investment in small hydropower projects about 250 billion yuan, wind power projects about 64 billion yuan, solar PV power generation of about 23 billion yuan, biomass power generation of about 20 billion yuan. Private investment in wind power equipment, solar cells and components, crystal silicon manufacturing area of 230 billion yuan, solar water heaters investment of about 220 billion yuan in the whole industry.
From the power generation installed capacity, more than 12,000 small hydropower projects, installed capacity 3800多万千瓦, accounted for the national small hydro-power installation of 63%, biomass direct-fired agriculture and forestry biomass power generation, garbage power generation projects more than 170, installed capacity of about 3.1 Million-kilowatt, accounting for the national biomass power generation installed capacity of half. Wind power Installed capacity of 690多万千瓦, accounting for the national wind power total installed capacity of 15%, solar photovoltaic power generation project Installed capacity 110多万千瓦, accounting for the national PV power Plant total volume of 37%.
In the field of new energy equipment manufacturing, private investment wind power equipment manufacturing capacity of about 32 Million-kilowatt, accounting for the national Wind power equipment, half of the total capacity of solar cells and components manufacturing capacity of about 25 Million-kilowatt, accounting for the national total capacity of 83%, solar crystal silicon manufacturing capacity of 100,000 tons, accounting for the total capacity of 80%. Solar water heater Cumulative installation of 220 million square meters of thermal area, its design, construction, manufacturing, services, mainly for private enterprises.
"New 36" proposed, "to encourage private capital to participate in power construction." Private capital is encouraged to participate in the construction of new energy industries such as wind, solar, geothermal, biomass, etc. ”
In order to implement the above spirit, the relevant department of the National Energy Bureau is developing supporting policies to solve problems such as the difficulty of grid-connected, the difficulty of the market and the difficulty of project approval.
"PV, for example, affects the development of photovoltaic projects in cities," said a private photovoltaic company. The local power supply department does not allow photovoltaic power generation systems to reverse power grids, even at the low pressure side of the spontaneous use of a lot of restrictions. ”
China Renewable Energy Large-scale development project (CRESP) Research report also pointed out: "On-grid acquisition and market elimination problem is the biggest bottleneck restricting the large-scale development of renewable energy generation in China." It is suggested that international experience should be used to establish a renewable energy quota system mainly for grid enterprises, so as to promote the synchronous connection between regional power grids and large range of elimination. ”
Because the internet is difficult, private enterprises will be directed at the grid monopoly. A local grid source explained: "New energy generation projects focused on resources and development planning, there is no specific elimination plan and supporting power grid projects." Even if the local power grid has been merged, it will be limited by the capacity of the region, the actual generation of power output limited, wind farm abandoned wind phenomenon. ”
In addition, some local governments and investment enterprises to circumvent the state approval, have been divided into construction, not conducive to intensive development.
Wind power, PV and other grid-connected, in addition to the energy planning management system, and the new energy characteristics are also related. "China New Energy Generation Development Research Report" pointed out that the new energy resources and energy demand in our country are in reverse distribution, the resources are dispersed, the energy density is low, the power generation has the characteristics of randomness, intermittence, fluctuation, etc. To the system operation and scheduling management put forward higher requirements.
