Reporting scope and data verification

GRI reference 102-50, 102-51, 102-52

This report covers the CLP Group’s sustainability performance for the calendar year ending 31 December 2020. It is published at the same time as the Annual Report. The previous CLP Sustainability and Annual reports were published in March 2020.

GRI reference 102-45, 102-48, 102-49

CLP reviews its reporting scope regularly to ensure the material impact of the Group’s overall portfolio is covered. In 2020, the reporting scopes of the following data points have been adjusted:

  • Health and Safety, Environmental (HSE): Any assets that have been operating during the year are included in the reporting scope. In 2020, additions to the reporting scope include: the new combined-cycle gas turbine (CCGT) generation unit (Unit D1) at Black Point Power Station and WE Station in Hong Kong, Laiwu III in Mainland China, Clean Solar Renewable Energy (CREPL) and Divine Solar Renewable Energy (DSPL) in India.

    Satpura Transco Private Limited (STPL) transmission network, acquired by CLP India in November 2019, was not included in the 2019 data points but has been included in the 2020 reporting cycle. Environmental data of the Paguthan power station, the power purchase agreements (PPA) of which expired in December 2018, were not included in the 2020 data points. Echo Group, a solar and LED lighting company, has been added to the safety scope since EnergyAustralia took full ownership of the business.

  • Operations: To reflect CLP’s growing investments in energy storage, an energy storage category was added to the Group’s total generation capacity and total energy sent out breakdown by asset type. It encompasses pumped storage and battery storage. The 2020 data points for energy storage includes Guangzhou Pumped Storage Power Station, Ballarat battery storage and Gannawarra battery storage in Australia.

  • Climate Vision 2050: While CLP continues to report on carbon intensity based on equity, the Group tracks its performance based on equity plus long-term capacity and energy purchase. This approach reflects more holistically on the developments of generation capacity from other sources. Starting from 2020, CLP also reports the total carbon dioxide emissions of the Group’s generation and energy storage portfolio to provide more transparency to the calculation of the Group’s carbon intensity.
