Current Main Problems and Solutions of China 's Electric Power Industry

With the economic and social development and people's living standards

improve, people's electricity demand is also growing trend. At the same

time, the power companies gradually to market. In this context, how to

take effective measures to develop the electricity market, improve the

level of marketing management is an important task for each power

companies can not be ignored.

So what is the current problem facing the power industry? How to

ensure that the consumption of the power industry in the direction of

healthy and orderly development? The main problems facing the current

power industry.

(一) With China's economy into the "new normal", power demand

growth slowed down significantly. Due to the lack of co-ordination of

power planning guidance, power installed capacity is still maintained

rapid growth, making the majority of the region there is greater than the

power supply demand for electricity. 2016, northeast, northwest power

grid surplus than in 2015 has intensified.

(二) in some areas the development of renewable energy too fast, the

problem has become increasingly prominent. In recent years, due to the

operation mechanism is not perfect, the power demand growth slows

down, the system peaking the lack of resources and power transmission

capacity is limited and other factors, China's abandoned water,

abandoned wind, abandoned light scale continues to rise, but part of the difficult areas Still vigorously develop renewable energy. In the first half,

the national wind power reached 32.3 billion kwh, the wind rate was

21%, an increase of 6 percentage points. Gansu, Xinjiang, Jilin, Inner

Mongolia, the wind rate was more than 30%. In addition, the

southwestern region abandoned water, northwest area of abandoned

light has also increased.

(三) the slow growth of electricity demand, power enterprises to further

increase the operating pressure. For power grid enterprises, driven by

the slow growth in demand for electricity, electricity sales growth is

weak, coupled with the power system reform will make the electricity

market competition intensifies, companies are difficult to rely on

electricity sales revenue, profit growth. For power generation enterprises,

thermal power equipment utilization hours continued to decline, the

Internet price has been lowered, coal prices rise, corporate profit

margins further shrink.

Related advice

(一) to strengthen the overall planning of electricity to promote the

healthy development of the power industry.

First, consider the resource endowment, environmental space, electricity

demand and other factors, unified planning power and power grid

development goals, structure and layout, between power and power grid,

power and power, between the central and local planning. Second, co-ordinate the development of renewable energy and consumer market,

scientifically determine the scale and layout of renewable energy

projects, simultaneous planning and construction of peak power supply,

outgoing channel. The third is to speed up the construction of Huainan -

Nanjing - Shanghai and other cross - border transmission projects, as

soon as possible to approve the follow - up projects, as soon as possible

to start a number of pre - project work, as soon as possible clear delivery

power to achieve delivery and cross - regional transmission construction

progress.

(二) power surplus phenomenon is obvious, need to adjust the orderly.

ncrease efforts to eliminate backward units, detailed elimination of

backward production capacity plan, strengthen supervision and

management.

(三) the combination of administrative and market means to promote

the consumption of renewable energy.

To build a nationwide balance of power and electricity, peak load sharing

and a variety of renewable resources to complement the energy

consumption platform to expand the scope of renewable energy

consumption, improve the proportion of renewable energy consumption.

Second, increase the new energy station energy storage facilities, etc., to

improve the system peaking capacity. Third, improve the market

mechanism, research and development of flexible power generation and load side of the peak and valley price mechanism to guide power

generation enterprises and power users wrong peak power; speed up

the establishment of auxiliary services market, improve the enthusiasm

of conventional thermal power units involved in peaking. Fourth, to

further improve the new energy consumption with the system,

abandoned areas to further strengthen the power of local government

communication and coordination.
