In order to implement the "Energy Development Strategic Action Plan (2014-2020)" of the General Office of the State Council, the target requirements of wind power and photovoltaic electricity prices to achieve grid parity by 2020, reasonably guide new energy investment, and promote photovoltaic power generation and wind power generation industries. To achieve healthy and orderly development, in accordance with the Renewable Energy Law, it was decided to adjust the new energy benchmark on-grid electricity price policy. After research, the relevant matters are now notified as follows:
1. Reduce the benchmark grid-in electricity price for photovoltaic power generation and onshore wind power
Based on the current technological progress and cost reduction of the new energy industry, the 2017 The benchmark on-grid electricity price for newly-built photovoltaic power generation after January 1, 2018 and for onshore wind power newly approved for construction after January 1, 2018. Please see Attachment 1 and Attachment 2 for specific prices. Before 2018, if the construction cost of new onshore wind power projects has a major impact Changes, the state can adjust the above-mentioned benchmark electricity prices according to actual conditions. The previously announced benchmark on-grid electricity price policy for new onshore wind power in the above-mentioned years will no longer be implemented. The part of the on-grid electricity price of photovoltaic power generation and onshore wind power that is within the benchmark on-grid electricity price of local coal-fired units (including desulfurization, denitrification, and dust removal electricity prices) will be settled by the local provincial power grid; the higher part will be subsidized through the National Renewable Energy Development Fund.
2. Clarify the benchmark on-grid electricity price for offshore wind power
For offshore wind power projects that are not subject to bidding, differentiate between offshore wind power and intertidal wind power to determine the on-grid electricity price. The benchmark on-grid electricity price for offshore wind power projects is 0.85 yuan per kilowatt hour, and the benchmark on-grid electricity price for intertidal wind power projects is 0.75 yuan per kilowatt hour. The part of the offshore wind power on-grid electricity price that is within the benchmark on-grid electricity price of local coal-fired units (including desulfurization, denitrification, and dust removal electricity prices) will be settled by the local provincial power grid; the higher part will be subsidized through the National Renewable Energy Development Fund.
3. Encourage the determination of new energy electricity prices through market-based methods such as bidding
The state encourages localities to determine new energy projects such as photovoltaic power generation, onshore wind power, and offshore wind power through market competition such as bidding. The owner and the on-grid electricity price, but the price formed through market competition shall not be higher than the national benchmark on-grid electricity price for photovoltaic power generation, onshore wind power, and offshore wind power in similar resource areas. The price is determined through market competition such as bidding. The part within the benchmark on-grid electricity price for local coal-fired units (including desulfurization, denitrification, and dust removal electricity prices) will be settled by the local provincial power grid; the higher part will be subsidized by the National Renewable Energy Development Fund. .
IV. Other relevant requirements
Each new energy power generation enterprise and power grid enterprise must truly and completely record and preserve information such as the online transaction volume, price and subsidy amount of relevant power generation projects. Accept Supervision and inspection by relevant departments. Pricing authorities at all levels should strengthen supervision over the implementation of new energy grid-connected tariffs and the settlement of renewable energy development fund subsidies, and urge the implementation of relevant on-grid tariff policies.
The above regulations will be implemented from January 1, 2017.
Wind power and photovoltaics are new energy sources that China is focusing on developing. The power grid must fully absorb them and give priority to their use.. Hydropower also requires priority use of the power grid during flood periods. This is a comprehensive consideration of a series of factors such as environmental protection and carbon emission reduction by the state. So there is nothing the power grid can do! Why is it called "junk electricity"? There are mainly two aspects.
First, photovoltaic and wind power have small installed capacity and are scattered, making it difficult to meet the peak load regulation needs of the power grid! To put it simply, when the weather is sunny and the wind blows, the insufficient thermal power will be supplemented. When the short-term demand for electricity increases rapidly, photovoltaic and wind power cannot satisfy it. On cloudy days and when there is no wind, the power plant is dead. When there is a power shortage, thermal power is used! And the price of new energy on-grid electricity is relatively high! This means that when the sun comes up, the thermal power load is reduced, and when the sun goes down, the thermal power load is increased. For the power grid, constant adjustments are required, which is not conducive to the security and economic operation of the power grid. Second, wind power and photovoltaics are not stable enough, causing harmonics to be transmitted back to the power grid system, which will increase power losses and affect motor efficiency, which will affect high-precision manufacturing! These two reasons should be the reason why photovoltaic and wind power are called "garbage power".
Both are new energy power generation, which are currently encouraged and vigorously developed by the state, and there are huge state subsidies. , the grid settlement price of thermal power is about 0.3 yuan per kilowatt hour, and the price of wind power and photovoltaic power generation ranges from 0.3 to 0.8 yuan.
Both types of power generation had a fatal flaw at the time, which was their intermittency. Solar power generated electricity during the day and could not generate electricity at night. Wind power could generate electricity when there was wind, but could not generate electricity when there was no wind. These two types of power generation are actually not welcomed by the power grid, but due to the state's support for new energy and the requirements for energy conservation and emission reduction, the power grid company must accept it unconditionally.
There are more and more of these two types of power generation, which bring instability to the power grid. At present, we mainly rely on thermal power peak shaving, pumped water energy storage, wind power heating, and the construction of energy storage power stations to solve intermittent problems. At the same time, wind and solar power forecasts are becoming more and more accurate, which also reduces the pressure on power grid regulation.
