WEPS is a programme under ESKOM by which local electricity producers can sell electricity to ESKOM. WEPS is
designed as a cost-reflective tariff to recover the cost of energy (generation), network services (transmission) and other costs necessary to deliver a wholesale electricity service. This will include costs for losses and wheeling through the distribution system.

The term “load factor” (sometimes referred to as “capacity factor” though definitions may differ) is defined as an installation’s average load divided by its peak load. For intermittent renewables, like PV and wind, which cannot always be dispatched according to the installed capacity, the load factor shows how much electricity is produced for a given installed peak capacity. Load factor accuracy is important when assessing the feasibility of intermittent renewables.
