Eskom pilots incentive designed to claw back 5 TWh of energy-intensive demand

Date: Aug 7, 2018

tate-owned electricity producer Eskom has confirmed that it has entered into a sales incentive pilot programme with nine large industrial customers in a bid to stabilise sales to electricity-intensive industries.

The two-year sales incentive pilot programme, which commenced on June 1, has the potential to stimulate additional sales of up to 5 TWh and generate revenue of R3-billion over two years, the utility tells Engineering News Online.

Eskom did not disclose the identities of the customers, but indicated that the companies were in the gold and platinum mining, aluminium, steel, ferrochrome and manganese sectors.

The cash-strapped utility has been hemorrhaging energy-intensive customers over the past ten years, during which industries were forced to adjust both to load-shedding and surging tariffs.

Eskom’s sales to key industrial customers have declined from 90 TWh in 2007/8 to 75 TWh in 2017/18, a fall of nearly 17%. Over the same period, national sales have declined 2%, from 214.8 TWh to 210.3 TWh over 10 years, with key industrial customers currently comprising 36% of national sales, having represented 42% in 2007/8.

Under the pilot programme, dubbed ‘the offer’, large customers are incentivised to increase their base sales, compared to a historical baseline, while tariffs and tariff structures remain unchanged.

“The pilot programme is a standard offering to all customers whose current consumption is more than 100 GWh a year. The volume of incentivised incremental sales on offer is limited and applications are evaluated against set criteria and finalised through a standardised contractual agreement,” Eskom explains.

The actual revenue impact will be dependent on the success of the scheme.

Eskom reports that it has discussed the pilot with the National Energy Regulator of South Africa (Nersa), but a formal engagement would arise only should it be permanently implemented, or if a change to the current tariff structure is proposed.
