Renewable Energy MARKET INTELLIGENCE REPORT 2025 WESTERN CAPE

The report outlines three primary investment opportunities in the Western Cape's renewable energy sector: embedded solar PV for C&I and agricultural users, large-scale wind and solar projects, and behind-the-meter (BTM) lithium-ion storage. While the market is driven by rising electricity costs, decarbonisation pressures from export markets (such as the EU's CBAM), and a liberalising regulatory framework (Electricity Regulation Amendment Act of 2024), it faces significant barriers. These include severe grid constraints, administrative backlogs in municipalities, a shortage of specialised technical skills, and a high reliance on imported battery components, particularly from China.

• The embedded solar PV market for agricultural, commercial, and industrial (C&I) users in the Western Cape is currently valued at R6 billion with 440 MW of installed capacity, and is projected to grow to approximately 1,500 MW (R20 billion) by 2030.
• Large-scale renewable energy in the Western Cape currently consists of 465 MW of solar PV and 958 MW of wind power. Future growth is constrained by grid capacity, but the implementation of a 10% curtailment cap could unlock an additional 2,680 MW in wind projects, representing R45 billion in potential investment.
• The market for behind-the-meter (BTM) lithium-ion storage for C&I users is valued at approximately R750 million (170 MWh) in 2024 and is expected to reach R2.3 billion (540 MWh) by 2030.
• Rising electricity costs are a primary driver for embedded PV; Eskom tariffs for agricultural, commercial, and industrial customers have increased over 700% in nominal terms and tripled in real terms since 2005.
• International sustainability regulations, such as the EU's Carbon Border Adjustment Mechanism (CBAM) and the Corporate Sustainability Reporting Directive (CSRD), are forcing Western Cape exporters to adopt renewable energy to maintain market access.
• Grid constraints remain a critical barrier for large-scale projects, as the Western Cape supply area had effectively zero available connection capacity according to Eskom's latest Generation Capacity Assessment.
• Municipalities in the Western Cape face administrative burdens and resource constraints, leading to application backlogs of several months for the registration of PV installations.
• The BTM storage sector is highly dependent on imports, with nearly 40% of all lithium-ion cells and batteries coming from China, leaving the market vulnerable to supply chain disruptions and exchange rate fluctuations.
• There is a significant workforce shortage in the embedded solar PV value chain, particularly in the installation and EPC stages, which increases costs and delays project completion.
• The Electricity Regulation Amendment Act of 2024 aims to liberalise the energy market by establishing an independent Transmission System Operator (TSO) and facilitating competitive wholesale and retail electricity trading.
