JOHANNESBURG, Oct 8 (Reuters)South African power utility Eskom is still seeking funding for its shift from coal to greener fuels, but hopes to announce a deal at next year’s COP26 climate conference after talks with lenders including the World Bank, its chief executive said on Thursday.

Eskom, which generates 90% of South Africa’s power, has a 488 billion rand ($29.3 billion) debt burden and has imposed intermittent blackouts, denting economic growth and hurting investment.

The utility is in talks over funding with local and international developmental finance institutions, including the World Bank, and has received letters of support in principle, Andre de Ruyter told Reuters on the sidelines of the Joburg Indaba mining conference.

Eskom is still engaging on how those transactions would be structured, but hopes to make an announcement at the COP26 climate summit to be held in Glasgow in November 2021, he said.

Eskom is modelling options to repurpose its aging power stations into renewable or gas power plants and use vacant mining land for wind or solar farms, said De Ruyter.

Up to 12,000 megawatts (MW) of Eskom’s installed capacity will need to be decommissioned in the next decade, according to South Africa’s energy plan.

“We would be able to reduce the interest burden while also contributing to an improved emission profile and ultimately also creating jobs as we erect these renewable plants,” said De Ruyter.

“If we simply pull the plug on the old coal-fired power stations that have reached the end of their design life… then we will leave those communities in the lurch and that is not what we
