South Africa’s Energy Revolution: How Eskom is Removing Barriers to Grid Integration for Solar Power

Streamlined Registration Process Marks Major Shift in Energy Policy

Eskom, South Africa’s state-owned power utility, has implemented sweeping changes to its small-scale embedded generation (SSEG) registration framework that significantly reduces both the complexity and cost for residential and commercial customers seeking to connect renewable energy systems to the national grid. The revised regulations, effective October 1, represent a fundamental shift in how South Africans can participate in the country’s energy transition while maintaining grid stability and safety standards., according to market trends

Key Regulatory Changes and Cost Benefits

The most substantial change involves who can certify residential SSEG installations. Previously requiring sign-off from Engineering Council of South Africa (ECSA)-registered professionals, the new rules permit Department of Employment and Labour (DEL)-registered persons—including installation electricians and master installation electricians—to certify systems. This change alone is expected to dramatically reduce certification costs and waiting times for homeowners., according to recent innovations

The financial benefits are equally significant: Eskom has eliminated all registration and connection fees for households with solar systems up to 50 kVA until March 2026. For a typical 16 kVA rooftop solar installation, this translates to savings exceeding R9,000 in connection costs. Households with solar PV systems up to 50 kVA continue to be exempt from registration fees and smart meter installation charges, while non-residential customers maintain the previous year’s connection charges, ensuring continued cost savings across all customer segments., according to technology trends

Simplified Documentation Requirements

The utility has streamlined the required documentation to two primary documents: a valid certificate of compliance and a basic embedded generator installation compliance test report, both requiring sign-off by a registered person. This reduction in bureaucratic hurdles addresses previous customer complaints about complicated processes while maintaining essential safety standards.

Agnes Mlambo, Eskom Distribution acting group executive, emphasized that “customers said the previous process felt complicated and costly and Eskom has responded by streamlining compliance and introducing cost relief measures so that more South Africans can participate in the clean energy transition with confidence.”, according to market trends

Registration Mandate and Exemptions

Under National Energy Regulator of South Africa (Nersa) regulations, all businesses and households with embedded generation systems below 100 kVA—including solar PV installations—must register with Eskom as electricity licensees, regardless of whether they export electricity to the grid. This requirement ensures proper oversight and maintains grid integrity., according to industry analysis

The only exemption applies to completely off-grid systems that operate independently of Eskom’s network, provided customers can demonstrate their systems function without connection to the utility’s infrastructure. This distinction ensures that truly independent power producers aren’t burdened with unnecessary regulatory requirements while maintaining safety standards for grid-connected systems.

Long-Term Industry Collaboration

Eskom’s revised SSEG framework represents the culmination of extensive industry collaboration dating back to 2015. The utility has worked closely with multiple stakeholders including:

• South African Bureau of Standards
• South African Photovoltaic Industry Association
• Association for Municipal Electricity Distributors
• National Rationalised Specifications Standing Committee
• Eskom independent power producer stakeholders

This multi-year collaborative effort has focused on developing solutions that balance accessibility with safety, resulting in the current simplified framework that maintains rigorous safety standards while reducing barriers to entry., as covered previously

Future Benefits for Registered Customers

Beyond immediate cost savings, registered SSEG customers gain access to future benefits that enhance the return on their renewable energy investments. Mlambo notes that “registered customers can benefit from future tariff structures that make it possible to sign up for demand-response products and pay less for electricity by shifting energy use to lower-cost periods.”

Additionally, customers exporting power to the grid can take advantage of the Nersa-approved Homeflex tariff, which provides credits for exported energy. This mechanism not only improves investment returns but also creates financial incentives for contributing excess renewable energy to the national grid.

Historical Context and Regulatory Evolution

The current changes represent the latest step in a gradual regulatory evolution. Before 2019, only medium-voltage customers (above 1,000 V) could operate embedded generators in parallel with Eskom’s network. The utility expanded this to include low-voltage customers in April 2020, opening opportunities for residential and small business users.

During the interim period without formal low-voltage regulations, the industry relied on the SSEG NRS097 distribution standard to ensure safe interconnection of embedded generation. The initial requirement for ECSA-registered professional sign-offs proved costly for many homeowners, with professional fees varying widely and falling outside Eskom’s control.

Commitment to South Africa’s Energy Future

Eskom remains committed to supporting South Africa’s broader energy transition through safe, affordable, and compliant integration of SSEG systems. The utility continues exploring solutions for prepaid connections and other innovative approaches while maintaining grid integrity and reliability.

The simplified registration process represents a significant milestone in South Africa’s energy landscape, potentially accelerating renewable energy adoption while maintaining the technical standards necessary for a stable national grid. As Mlambo states, “Our goal is to make it as simple, safe and cost-effective as possible for customers to connect legally, while ensuring the stability and safety of the national grid.”
