Eskom’s Proposed Grid Regulations: A Misstep or a Strategic Play?

South Africa’s dominant power supplier, Eskom, has recently tabled new regulations concerning private access to the national electricity grid, triggering a wave of dissent from various sectors, including the Democratic Alliance (DA). The DA plans to urge the National Energy Regulator of South Africa (Nersa) to scrutinize and ultimately dismiss these regulations.

Eskom’s Controversial Proposal

Eskom aims to democratize access to the national power grid, with particular attention to independent power producers. However, the rules mandate renewable electricity producers to fulfill extra compliance steps, encompassing environmental and water usage rights, procurement agreements, and a comprehensive year’s data on solar availability or two years’ data on wind availability.

Backlash and Implications

This proposed regulatory framework has ignited a barrage of criticism from both businesses and political parties. The DA perceives these measures as a potential deterrent for energy sector investments by Independent Power Producers (IPPs) – a grim prospect amidst the ongoing electricity crisis. “What Eskom is doing now, through these proposed grid regulations, is essentially anti-competitive behaviour. It is leveraging its monopoly to create barriers to entry in the energy market for IPPs,” the DA proclaimed.

The party further accuses Eskom of neglecting to conduct an economic impact assessment to measure the potential repercussions these new rules could have on the energy sector. Eskom is effectively amplifying the investment risk premium, pressuring IPPs to invest more in power generation projects without guaranteeing grid access.

The DA declares this move as detrimental, “It is a shot in the foot that will reverse all the gains that have been made thus far to increase the proportion of independent power generation to the energy mix“. Rather than exercising authority over grid access, Eskom ought to encourage private sector investments in the grid, the party suggests.

Eskom’s Grid Upgrade Plans and the Risk of Overloading

Simultaneously, Eskom seeks to modernize its existing grid system. It intends to capitalize on the private sector’s liquidity, yet without surrendering grid ownership. Underdeveloped grid systems, however, have impeded the progress of renewable energy projects, raising the specter of a national blackout due to grid overloading.

Electricity Minister Kgosientsho Ramokgopa and Professor Sampson Mamphweli from the National Energy Development Institute liken the grid capacity to a water pipeline: overload it, and it could burst. Conversely, energy experts like Rein Henkeman, Managing Director of Alumo Energy, disputes this assertion. He labels the concerns over a sudden large-scale solar integration into the grid as unfounded, given the lengthy implementation timeline.

A Call for Infrastructure Upgrades

Henkeman emphasizes, “Large-scale solar projects require months to construct, and the planning, and permit application and allocation phases can take up to three to five years to complete. As a result, the national grid won’t experience a sudden surge of solar energy for several more years, at the very least. This should give the utility ample time to enhance its infrastructure to be ready for solar“.

The real problem, according to Henkeman, lies in Eskom’s outdated generation equipment, which can’t handle abrupt fluctuations in the transmission network. He concludes that the issue isn’t with solar power but rather the urgent need for an electrical infrastructure upgrade.
