VOLUNTARY ANNOUNCEMENT

This announcement is made by Beijing Jingneng Clean Energy Co., Limited (the "Company", together with its subsidiaries, the "Group") on a voluntary basis.

Recently, the Company received the Notice of the Beijing Municipal Commission of Development and

Reform on Adjusting the Ex-factory Price of Heat Energy of Gas-fired Power Plants in Beijing 《( 北京市 發展和改革委員會關於調整本市燃氣電廠熱力出廠價格的通知》) and the Notice of the Beijing

Municipal Commission of Development and Reform on Relevant Issues Concerning the On-gridTariff of Gas-firedPower Plants in Beijing 《( 北 京 市 發 展 和 改 革 委 員 會 關 於 本 市 燃 氣 電 廠 上 網 電 價 有

關問題的通知》), pursuant to which, as approved by the Beijing Municipal Government, based on the adjustments to non-resident natural gas price in Beijing and national value-added tax rate, the ex-factory price of heat energy and on-grid tariffs of gas-fired power plants in Beijing have been adjusted since 15 November 2019.

The change in ex-factory price (tax inclusive) of heat energy and on-grid tariffs of gas-fired power plants as a result of the adjustments in non-resident natural gas price in Beijing and national value-added tax rate has the following major effects on the Group: 1) due to the decrease in value-added tax rate, the amount of value-added tax payable by relevant subsidiaries of the Company will be reduced and the tax refund income from heat supply to residents will be reduced correspondingly. The reduction of tax refund income is related to the tax refund policy; and 2) since value-added tax is a price exclusive tax, the ex-factory price of heat energy and electricity excluding tax will not be adjusted, and therefore the Group's results for 2019 will not be affected. In case of any subsequent effect on the Group's results, we will respond actively through the synergistic effect of each segment of the Group.

The Group will continue to optimize heat energy and electricity generation and improve the energy utilization rate of generators, so as to achieve effective control over costs.

Shareholders and investors are advised to exercise caution while dealing in the securities of the Company.
