Reducing CBAM Liability Through Renewable Energy PPAs in South Africa

Reducing CBAM Liability Through Renewable Energy PPAs in South Africa

For electricity-intensive South African exporters, a renewable energy power purchase agreement (PPA) is the single most impactful strategy for reducing CBAM liability. This guide explains how PPAs work in the South African context and how to structure them for maximum CBAM benefit.

Why Renewable Electricity Matters for CBAM

South Africa's coal-dominated electricity grid creates a significant CBAM disadvantage for electricity-intensive exporters. The national grid emission factor of 0.9 kgCO₂/kWh means that every megawatt-hour of electricity consumed in production adds 0.9 tonnes of CO₂ to your embedded carbon.

By switching to renewable electricity through a PPA, you replace the 0.9 kgCO₂/kWh grid factor with the emission factor of your renewable source — typically 0.02–0.05 kgCO₂/kWh for solar PV or wind.

Types of Renewable Energy PPAs in South Africa

1. Direct Bilateral PPAs A direct contract between your company and a renewable energy IPP. The IPP builds and operates a solar or wind farm, and you purchase the electricity at a fixed price for 10–20 years. This is the most common structure for large industrial consumers.

2. Eskom LPU Renewable Programme Eskom's Large Power User programme allows industrial consumers to procure renewable electricity through Eskom's grid. The programme is still developing, but offers a simpler procurement pathway than direct bilateral PPAs.

3. Wheeling Agreements Renewable electricity generated at a remote location (e.g., a solar farm in the Northern Cape) is "wheeled" across the Eskom grid to your facility. A wheeling agreement with Eskom is required to transport the electricity.

4. On-Site Generation Installing solar PV panels or wind turbines at your production facility. This is the simplest structure from a CBAM documentation perspective, as the renewable generation is directly linked to your consumption.

CBAM Documentation Requirements for PPAs

To claim the renewable electricity emission factor for CBAM purposes, you need:

1. ▸PPA agreement — Confirming the renewable energy source and the contracted volume
2. ▸Electricity delivery records — Monthly records confirming actual renewable generation and delivery
3. ▸Renewable energy certificates (RECs) — Certificates confirming the renewable origin of the electricity
4. ▸Third-party verification — A verifier's confirmation that the emission factor used is appropriate

The Financial Case for Renewable PPAs

Beyond CBAM compliance, renewable energy PPAs offer significant financial benefits:

• ▸Price certainty — Fixed electricity prices for 10–20 years, hedging against Eskom tariff increases
• ▸CBAM cost reduction — Lower embedded carbon means lower CBAM certificate costs
• ▸Competitive advantage — Lower CBAM liability makes your products more competitive in EU markets
• ▸ESG credentials — Renewable electricity supports your sustainability reporting and ESG ratings
