Zambia Opens Electricity Market To Private Renewable Energy Developers And Mining Customers

Zambia is restructuring its electricity sector by introducing an open-access electricity market aimed at increasing private participation, expanding renewable generation, and improving power reliability. The reform reduces the traditional dominance of state-owned utility ZESCO, which has historically played a central role in electricity generation, purchasing, transmission, and supply.

The need for reform became more urgent after severe regional droughts affected Zambia’s hydropower generation. Heavy dependence on hydroelectricity exposed the country to significant supply shortages when water levels fell, affecting households, businesses, and industrial consumers.

Under the new open-access framework, independent power producers can generate electricity and sell it directly to eligible customers. Large electricity consumers, including mining companies, can negotiate power purchase agreements with private generators. Developers can also use existing transmission infrastructure owned by ZESCO, Copperbelt Energy Corporation, and other network operators to transport electricity to customers by paying applicable network charges.

The new structure also creates opportunities for private power traders and aggregators. Companies such as GreenCo Power Services can act as intermediaries between renewable energy producers and large electricity consumers. These companies can purchase electricity from independent solar and wind developers through long-term agreements and subsequently supply power to commercial customers or regional electricity markets.

Such arrangements can improve the bankability of renewable energy projects by providing developers with reliable commercial buyers. They can also reduce dependence on direct government-backed guarantees, potentially making it easier for projects to secure private debt and equity financing.

Zambia’s mining sector is expected to be an important participant in the evolving market. Copper production requires a stable and continuous electricity supply, while global demand for copper is increasing due to its use in electrification, renewable energy infrastructure, and other technologies. Direct agreements with renewable energy producers could help mining companies diversify their electricity sources while reducing pressure on Zambia’s hydropower-dependent system.

The reform could also allow ZESCO to allocate more of its available generation capacity toward households and domestic consumers as industrial customers increasingly source electricity through private arrangements.

However, successful implementation will depend on transparent market rules, competitive and balanced transmission charges, and clear separation between electricity generation, grid operations, and commercial supply. Regulators and development partners are working to establish market guidelines and standardized procedures for participants.

Zambia’s open-access electricity model is therefore creating a new framework for private investment, renewable energy development, and direct electricity trading, while seeking to strengthen the country’s long-term power security.
