1 Situation & Prospects of Electric Power

1.1 China’s Non-fossil Energy Development Goal

➢ China’s energy development strategy is developing non-fossil

energy and replacing fossil energy gradually, to achieve

sustainable development of economy and reduction of pollution

and CO2 emissions.

➢ By 2030, CO2 emissions will peak and China will try to reach it

ahead of schedule. The CO2 emissions intensity will be reduced

by 60-65% compared with that in 2005.

➢ China is making great efforts to increase the share of non-fossil

energy in primary energy consumption to 15% by 2020, and

20% by 2030.

➢China's wind and PV power have been developed

very fast in recent years. However, due to the

instability, there is a need to build energy storage

power stations.

➢ Pumped-hydro station is limited by site resources, and

battery storage is uneconomical. Therefore, some

regions have limited acceptance of wind and PV

power, leading to a waste of energy.

➢ CSP units with thermal energy storage (TES) can maintain stable power output,

and with big enough TES, it can generate power 24-hour continuously. Therefore, it

can respond rapidly to primary and second frequency regulation in power grid.

➢ Role of CSP in power grid :

1）As base load units of power grid；

2）As peak load units of power grid.

➢ Power grid with CSP can improve acceptance proportion of wind and PV power.

➢ According to preliminary estimation, there is about 970 thousand km2 available

land with DNI＞1700kWh/m2 in China, mainly in Inner Mongolia, Tibet,

Qinghai, Xinjiang and Gansu, where most land is gobi or desert.

➢ If 100 thousand km2 land is used

for CSP, annual power generation

may reach about 5.4 trillion kWh .

➢ If the units 100% output hours is

3500, available installed capacity is

about 1.5 billion kW.

CSP LCOE Prediction in China

➢ Current investment cost for CSP plant

is ¥25,000-30,000 /kW. By the end of

2020, It is expected that the investment

cost will be reduced to ¥15,000/kW, and

the LCOE will be lowered to ¥0.75/kWh.

4.5 Summary

➢With the guidance and support of national policy, China has started the large-scale

development of CSP.

➢ CSP will play a significant role in China’s energy transformation with bright

development prospects.

➢ The increase of China’s CSP projects will provide a good development opportunity for

Chinese and overseas manufacturers of equipment and materials.

➢With the increasing domestic CSP construction experience, Chinese enterprises will

greatly improve the technology and product quality, contributing substantially to the

global CSP development.
