For German and European service providers active in the energy sector, Zambia presents significant potential for business development. There are clear needs across the solar energy and storage value chain, including pro-ject development and financing, equipment manufacturing, system inte-gration and contracting.

The Zambian government has set a target to increase its installed solar and wind capacity to 600 MW by 2030. However, the current installed capacity for solar photovoltaics is only 90 MWp, indicating significant underutilisation of Zambia's potential in the renewable energy sector.

Private companies also trade in electricity in Zambia. The largest of these, Copperbelt Energy Corporation Plc (CEC), buys electricity primarily from ZESCO and sells it to the various mines in the Copperbelt Province. It also operates its own generators, most of which run on fossil fuels.

The Electricity Act regulates the generation, trans-mission, distribution and supply of electricity to enhance the security and reliability of electricity sup-ply in Zambia. It codifies the rules on tariff setting and introduces the concept of intermediary power trading, a concept that was missing from the previous regulatory framework.

In that case, the PV production is used to reduce the electricity bill and/ or the diesel fuel bill. As of 2022, the cost of diesel in Zambia was around USD 1.5/litre (Global Petrol Prices, sd) and the efficiency of a generator varies between 25% and 35% if operated at at least 30% of its capacity (Skyllas-Ka-zacos, 2012).
