China is the world's largest electricity producer. It overtook the United States in 2011 after rapid growth since the early 1990s. In 2021, China produced 8,534 terawatt-hour (TWh) of electricity, which was approximately 30% of the world's electricity production.{{Cite web | url=https://www.bp.com/content/dam/bp/business-sites/en/global/corporate/pdfs/energy-economics/statistical-review/bp-stats-review-2022-full-report.pdf | title=bp Statistical Review of World Energy | year=2022 | website=www.bp.com}}

Most of the electricity in China comes from coal power, which accounted for 62% of electricity generation in 2021 and is a big part of greenhouse gas emissions by China. Power generated from renewable energy has also been continuously increasing in the country. The national electricity generation from renewable energy reached 594.7 TWh in Q1 2023, an increase of 11.4% year-on-year, including 342.2 TWh of wind and solar power, up 27.8% year-on-year.{{cite web|url=https://global.chinadaily.com.cn/a/202304/28/WS644b1dbda310b6054fad04d9.html |title=China's first desert-based green power plant on grid - Chinadaily.com.cn |language=zh |publisher=Global.chinadaily.com.cn |date=28 April 2023 |accessdate=5 June 2023}}

As of February 2023, China has 55 nuclear plants with 57 GW of power in operation, 22 under construction with 24 GW and more than 70 planned with 88 GW. About 5% of electricity in the country comes from nuclear energy.{{cite web |url=https://www.forbes.com/sites/thebakersinstitute/2023/05/17/how-long-will-it-take-for-chinas-nuclear-power-to-replace-coal/?sh=21f618dd3b1b |title=How Long Will It Take For China's Nuclear Power To Replace Coal? |work=Forbes.com |date= |accessdate=5 June 2023}}

China has two wide area synchronous grids, the State Grid and the China Southern Power Grid. The northern power grids were synchronized in 2005.{{Cite book|last1=Wu|first1=Wei|last2=He|first2=Zhao|last3=Guo|first3=Qiang|date=June 2005|chapter=China power grid and its future development|pages=1533–1535|doi=10.1109/pes.2005.1489157|title=IEEE Power Engineering Society General Meeting, 2005|isbn=0-7803-9157-8|s2cid=30004029}}

Since 2011 all Chinese provinces are interconnected. The two grids are joined by HVDC back-to-back connections.{{Cite book|title=Global energy interconnection|last=Zhenya|first=Liu|isbn=9780128044063|page=45|quote=After the completion and commissioning of Tibet’s ±400 kV DC interconnected power grid in December 2011, China has achieved nationwide interconnections covering all its territories other than Taiwan.|date=28 August 2015|publisher=Academic Press }}

China has abundant energy reserves with the world's fourth-largest coal reserves and massive hydroelectric resources. There is however a geographical mismatch between the location of the coal fields in the north-east (Heilongjiang, Jilin, and Liaoning) and north (Shanxi, Shaanxi, and Henan), hydropower in the south-west (Sichuan, Yunnan, and Tibet), and the fast-growing industrial load centers of the east (Shanghai-Zhejiang) and south (Guangdong, Fujian).{{Cite journal|last=Kambara|first=Tatsu|date=1992|title=The Energy Situation in China|url=https://www.jstor.org/stable/654899|journal=The China Quarterly|volume=131|issue=131|pages=608–636|doi=10.1017/S0305741000046312|jstor=654899|s2cid=154871503|issn=0305-7410|url-access=subscription}}{{Better source needed|reason=old|date=February 2022}}

History

In April 1996, an Electric Power Law was implemented, a major event in China's electric power industry. The law set out to promote the development of the electric power industry, to protect the legal rights of investors, managers, and consumers, and to regulate the generation, distribution, and consumption.{{cn|date=July 2024}}

Before 1994, electricity supply was managed by electric power bureaus of the provincial governments. Now utilities are managed by corporations outside of the government administration structure.{{cn|date=July 2024}}

To end the State Power Corporation's (SPC) monopoly of the power industry, China's State Council dismantled the corporation in December 2002 and set up 11 smaller companies. SPC had owned 46% of the country's electrical generation assets and 90% of the electrical supply assets. The smaller companies include two electric power grid operators, five electric power generation companies, and four relevant business companies. Each of the five electric power generation companies owns less than 20% (32 GW of electricity generation capacity) of China's market share for electric power generation. Ongoing reforms aim to separate power plants from power-supply networks, privatize a significant amount of state-owned property, encourage competition, and revamp pricing mechanisms.{{cite web |url=http://www.buyusa.gov/china/en/power.html |title=BuyUSA.gov Home |url-status=dead |archive-url=https://web.archive.org/web/20100620222039/https://www.buyusa.gov/china/en/power.html |archive-date=20 June 2010 |access-date=11 July 2021}}

In recent history, China's power industry is characterized by fast growth and an enormous installed base. In 2014, it had the largest installed electricity generation capacity in the world with 1505 GW and generated 5583 TWh{{cite web|url=https://www.cia.gov/the-world-factbook/countries/china/|title=The World Factbook|work=cia.gov|access-date=1 February 2016}} China also has the largest thermal power capacity, the largest hydropower capacity, the largest wind power capacity and the largest solar capacity in the world. Despite an expected rapid increase in installed capacity scheduled in 2014 for both wind and solar, and an expected increase to 60 GW in nuclear by 2020, coal will still account for between 65% and 75% of capacity in 2020.{{cite web|url=http://theenergycollective.com/michael-davidson/335271/china-s-electricity-sector-glance-2013|title=China and Electricity Overview – The Energy Collective|website=Theenergycollective.com|access-date=1 February 2016|archive-date=1 July 2018|archive-url=https://web.archive.org/web/20180701031933/http://www.theenergycollective.com/michael-davidson/335271/china-s-electricity-sector-glance-2013|url-status=dead}}

In Spring 2011, according to The New York Times, shortages of electricity existed, and power outages should be anticipated. The government-regulated price of electricity had not matched rising prices for coal.{{cite news |last=Bradsher |first=Keith |author-link=Keith Bradsher |date=24 May 2011 |title=China's Utilities Cut Energy Production, Defying Beijing |url=https://www.nytimes.com/2011/05/25/business/energy-environment/25coal.html |access-date=25 May 2011 |newspaper=The New York Times |quote=Balking at the high price of coal that fuels much of China’s electricity grid, the nation’s state-owned utility companies are defying government economic planners by deliberately reducing the amount of electricity they produce.}}

In 2020, Chinese Communist Party general secretary Xi Jinping announced that China aims to go carbon-neutral by 2060 in accordance with the Paris climate accord.{{Cite news |date=8 October 2020 |title=China Solar Stocks Are Surging After Xi's 2060 Carbon Pledge |url=https://www.bloomberg.com/news/articles/2020-10-08/china-s-solar-stocks-are-surging-after-xi-s-2060-carbon-pledge |access-date=5 January 2021 |work=Bloomberg News |language=en}}

In 2024, China's National Energy Administration ceased publishing data on power utilization by each generating source, impeding analysis of grid constraints.{{Cite news |date=July 1, 2024 |title=China Stops Publishing Data Highlighting Solar Power Constraints |url=https://www.bloomberg.com/news/articles/2024-07-01/china-stops-publishing-power-data-highlighting-solar-constraints |access-date=July 2, 2024 |work=Bloomberg News}}

Hydroelectricity is currently China's largest renewable energy source and the second overall after coal.

In 2021, China's total hydropower capacity reached 391 gigawatts (GW), an increase of 72 GW since 2015 when capacity stood at 319 GW. Of this increase, 20 GW was added in 2021. Hydropower accounted for approximately 16% of the country's installed power capacity and electricity generation. China represented about 29% of the world's total hydropower capacity and accounted for approximately 80% of global hydropower capacity additions in 2021. This includes both conventional and pumped-storage hydroelectricity, with most new developments concentrated in the western and southern regions.{{Cite web |title=Guide to Chinese Climate Policy; A: Hydropower |url=https://chineseclimatepolicy.oxfordenergy.org/book-content/domestic-policies/renewable-power/hydropower/ |access-date=23 February 2025 |website=The Oxford Institute for Energy Studies}}

According to the Energy Transitions Commission's 2019 report, China 2050: A Fully Developed Rich Zero-Carbon Economy, China has an estimated hydropower potential of up to 660 gigawatts (GW), of which about 500 GW is considered technically and economically feasible. The report projects that by 2050, wind and solar will generate nearly 70% of China's electricity.{{Cite web |date=November 2019 |title=China 2050: A fully developed rich zero-carbon economy |url=https://www.energy-transitions.org/publications/china-2050-a-fully-developed-rich-zero-carbon-economy/#download-form |access-date=23 February 2025 |website=Energy Transitions Commission}}

In the first half of 2023, China's hydropower capacity factor dropped to 30.5%, its lowest since at least 2015, due to severe drought conditions that reduced water availability. Hydropower output fell by 23%, the largest decline among all electricity sources. Globally, hydropower generation declined by 8.5%.{{Cite web |date=5 October 2023 |title=World’s electricity supply close to ‘peak emissions’ due to growth of wind and solar |url=https://www.carbonbrief.org/worlds-electricity-supply-close-to-peak-emissions-due-to-growth-of-wind-and-solar/ |access-date=23 February 2025 |website=Carbon Brief}}

=Nuclear power=

{{Main|Nuclear power in China}}

In terms of nuclear power generation, China will advance from a moderate development strategy to an accelerating development strategy. Nuclear power will play an even more important role in China's future power development. Especially in the developed coastal areas with heavy power loads, nuclear power will become the backbone of the power structure there. As of February 2023, China has 55 plants with 57 GW of power in operation, 22 under construction with 24 GW and more than 70 planned with 88 GW. About 5% of electricity in the country is due to nuclear energy.

These plants generated 417 TWh of electricity in 2022.

{{cite web|url=https://pris.iaea.org/PRIS/CountryStatistics/CountryDetails.aspx?current=CN |title=PRIS - Country Details |publisher=Pris.iaea.org |date= |accessdate=5 June 2023}} This percentage is expected to double every 10 years for several decades out. Plans are for 200 GW installed by 2030 which will include a large shift to Fast Breeder reactor and 1500 GW by the end of this century.

=Solar power=

{{main|Solar power in China}}

China is the world's largest market for both photovoltaics and solar thermal energy.

At the end of 2021 there was 306 GW of solar power in China providing 377,000 gigawatt-hours (GWh) of solar power electricity to the grid (out of total 7,770,000 GWh electricity power production.

In comparison, of the 7,623 TWh electricity produced in China in 2020, 261.1 TWh was generated by solar power, equivalent to 3.43% of total electricity production.{{cite web|url=https://chinaenergyportal.org/en/2020-electricity-other-energy-statistics-preliminary/|title=2020 electricity & other energy statistics (preliminary) – China Energy Portal |date=22 January 2021}}

China produced 272 Twh of electricity from natural gas in 2021.

China is a global powerhouse in the field of natural gas and one of the world's largest consumers and importers of natural gas. By the end of 2023, China's natural gas industry achieved major milestones, reflecting its important role in the country's energy transformation and its contribution to global natural gas market dynamics.

File:Jiangsu Suzhou Xiangcheng - Yuechengli area - Wangyu river IMG 7181 Huadian Wangting CCGT Power Plant.jpg

In 2023, China's natural gas production will increase significantly, with the total volume reaching approximately 229.7 billion cubic meters.{{Cite journal |last1=Gao |first1=Yun |last2=Wang |first2=Bei |last3=Hu |first3=Yidan |last4=Gao |first4=Yujie |last5=Hu |first5=Aolin |date=25 February 2024 |title=Development of China's natural gas: Review 2023 and outlook 2024 |url=https://www.cnki.net/KCMS/detail/detail.aspx?dbcode=CAPJ&dbname=CAPJLAST&filename=TRQG20240206001&uniplatform=OVERSEA&v=8xsT9mdy9KbCl3UW-9yKi8HjE3QrLJEiDNz5HWl0m3ep_epsbDp5lOdnHNkOyzwE |journal=Natural Gas Technology and Economy |volume=44 |issue=2 |pages=166–177}} This represents an increase of nearly 10 billion cubic meters per year and highlights China's efforts to increase domestic production and reduce reliance on imports. Despite the increase in domestic production, China remains the world's largest importer of liquefied natural gas (LNG), importing approximately 165.56 billion cubic meters of natural gas, of which LNG imports account for a large portion. This import capacity strengthens China's key role in the international LNG market and reflects its strategic measures to ensure energy security and supply stability.

Natural gas demand also rebounded, with apparent consumption increasing to 388.82 billion cubic meters. The growth highlights the growing role of natural gas in China's energy mix, driven by its economic recovery and transition to clean energy. Natural gas import dependence is 40.9%, indicating a balance between domestic production and imports to meet the country's energy needs.

=Biomass and waste=

China produced 169 Twh of electricity from biomass, geothermal and other renewable sources of energy in 2021.

Since the implementation of supportive policies beginning in 2006, investment and growth in the biomass power sector have accelerated. By 2019, investments had reached an impressive 150.2 billion yuan, climbing further to over 160 billion yuan by 2020, with more than 1,350 biomass projects underway across the country. This growth trajectory has been marked by a significant increase in installed capacity, which saw a record addition of 6,280 MW in 2019. Although the COVID-19 pandemic slightly slowed momentum in 2020, reducing the added capacity to 5,430 MW, the sector's growth trend continued upwards.{{Cite journal |last1=Guo |first1=Hong |last2=Cui |first2=Jie |last3=Li |first3=Junhao |date=1 November 2022 |title=Biomass power generation in China: Status, policies and recommendations |journal=Energy Reports |series=2022 The 5th International Conference on Electrical Engineering and Green Energy |volume=8 |pages=687–696 |doi=10.1016/j.egyr.2022.08.072 |issn=2352-4847|doi-access=free |bibcode=2022EnRep...8R.687G }}

Policy initiatives introduced in 2012 and 2016 have been pivotal in spurring the expansion of biomass power generation, leading to a substantial increase in power output. By 2019, biomass power generation had achieved a total output of 111,100 GWh, which further rose to 132,600 GWh in 2020, indicating robust year-on-year growth.

Storage

{{Expand section|date=September 2021}}

Energy storage plays a critical role in China's energy landscape, serving as a key enabler for the large-scale integration of renewable energy sources, such as wind and solar power, into the national grid. By mitigating the variability and intermittency of renewable energy, storage technologies facilitate a more stable and reliable power supply. China has been investing heavily in various storage solutions, including battery storage systems, pumped hydro storage, and flywheel energy storage, among others. These technologies not only help in balancing supply and demand but also in improving the overall efficiency and resilience of the power system.

In 2023, China's energy storage industry saw a dramatic surge, with its capacity expanding nearly fourfold due to advancements in technologies such as lithium-ion batteries. This remarkable growth was fueled by an investment exceeding 100 billion yuan (around US$13.9 billion) in recent years. By the close of 2023, the capacity within the sector of new-type energy storage soared to 31.39 gigawatts (GW), achieving an increase of over 260% compared to the previous year and almost a tenfold rise since 2020. The sector encompasses a range of innovative technologies, including electrochemical energy storage, compressed air energy storage, flywheel energy storage, and thermal energy storage, while pumped hydro storage is not included in this category.{{Cite web |date=26 January 2024 |title=China's energy storage capacity using new tech almost quadrupled in 2023: NEA |url=https://www.scmp.com/business/china-business/article/3249883/chinas-energy-storage-capacity-using-new-tech-almost-quadrupled-2023-national-energy-administration |access-date=27 February 2024 |website=South China Morning Post |language=en}}

Demand response

China's government has introduced a number of policies to promote the development of demand response, such as the 2012 "Interim Measures for the Management of Pilot Cities with Central Fiscal Funds to Support Electricity Demand Side Management."{{Cite journal |last1=Li |first1=Weilin |last2=Xu |first2=Peng |last3=Lu |first3=Xing |last4=Wang |first4=Huilong |last5=Pang |first5=Zhihong |date=1 November 2016 |title=Electricity demand response in China: Status, feasible market schemes and pilots |url=https://www.sciencedirect.com/science/article/pii/S036054421631194X |journal=Energy |volume=114 |pages=981–994 |doi=10.1016/j.energy.2016.08.081 |bibcode=2016Ene...114..981L |issn=0360-5442|url-access=subscription }}

The DR mechanism incentivizes electricity users to adjust their consumption patterns based on signals from grid operators, either reducing demand during peak hours (peak shaving) or increasing demand during off-peak hours (valley filling).

This flexibility is critical to maintaining grid stability and ensuring efficient use of energy resources.{{Cite web |title=China's Demand Response in Action |url=https://www.integralnewenergy.com/?p=34063 |access-date=27 February 2024 |website=www.integralnewenergy.com |language=en-US}}

China's approach to DR has included pilot projects in cities like Suzhou, Beijing, and Shanghai, focusing on tariff reforms and pricing strategies to encourage participation. Despite these efforts, challenges remain, such as the low participation rate of grid companies and the lack of transparency in grid operation data, hindering the widespread adoption of DR.

The types of demand response in China are:

  • Invitation DR: Local governments or grid companies invite consumers to participate in DR events, offering financial incentives for adjusting their load during specified times.{{Cite web |date=24 June 2015 |title=Demand Response in China |url=http://en.cnesa.org/latest-news/2015/6/24/demand-response-in-china |access-date=27 February 2024 |website=China Energy Storage Alliance |language=en-US}}
  • Real-time DR: Requires participants to respond to demand response signals in real-time, often with minimal notice, to address immediate grid needs.
  • Economic DR: Utilizes price signals, such as peak and off-peak rates, to motivate consumers to voluntarily adjust their energy usage according to the cost of electricity.

Transmission infrastructure

File:བོད་ལྗོངས་གློག་ཤུགས་ཀུང་སིས་བསྒྲགས།.jpg

The central government has made the creation of a unified national grid system a top economic priority to improve the efficiency of the whole power system and reduce the risk of localised energy shortages. It will also enable the country to tap the enormous hydro potential from western China to meet booming demand from the eastern coastal provinces. China is planning for smart grid and related Advanced Metering Infrastructure.{{cite news|url=https://blogs.wsj.com/chinarealtime/2010/09/29/china-wants-smart-grid-but-not-too-smart/|title=China Wants Smart Grid, But Not Too Smart|work=WSJ|date=29 September 2010|access-date=1 February 2016|last1=Areddy|first1=James}}

More than a third of electricity is used by industry.{{cite web|date=10 September 2021|title=Beijing power companies close to bankruptcy petition for price hikes|url=https://www.scmp.com/economy/china-economy/article/3148291/china-coal-fired-power-companies-verge-bankruptcy-petition|access-date=12 September 2021|website=South China Morning Post|language=en}} China consists of three largely self-governing territories: the mainland, Hong Kong, and Macau. The introduction of electricity to the country was not coordinated between the territories, leading to partially different electrical standards. Mainland China uses type A and I power plugs with 220 V and 50 Hz; Hong Kong and Macau both use type G power plugs with 220 V and 50 Hz. Inter-territorial travelers may therefore require a power adapter.
