Executive decision-makers’ guide to investing in renewable energy 2025
Summary
The 'Executive decision-makers’ guide to investing in renewable energy 2025' by GreenCape provides a strategic framework for South African businesses to transition to renewable energy. It details the differences between embedded generation and wheeling, outlines various financing models and bank-specific instruments, and explains the role of backup storage in enhancing energy resilience. The guide also lists available tax incentives and identifies systemic hurdles such as grid constraints and a dynamic policy environment.
Key insights
- Private procurement of renewable energy in South Africa has increased due to regulatory changes in 2022/23, with solar PV leading the market because of its lower cost, scalability, and shorter implementation timelines.
- Businesses can implement renewable energy via embedded generation (on-site installation like rooftop solar) or wheeling (procuring energy from remote plants via a transmission network). Wheeling is suitable for high-demand profiles and does not require on-site space, but it does not protect users from loadshedding.
- The guide outlines four primary financing models: outright purchase (full ownership and savings), debt finance (commercial loans over 5-10 years), lease-to-own (fixed monthly payments for 10 years), and Power Purchase Agreements (PPA), where the provider owns the asset and the customer pays for energy units at a rate lower than the utility tariff for 10-20 years.
- Major South African banks offer specific renewable energy instruments: ABSA provides the Bounce back solar loan (BBSL) and African Rainbow energy and power platform (AREP); FNB offers ecoEnergy Loans and alternative energy solutions (AES) up to R50 million; Standard Bank provides a Business solar loan (R10k - R10 million); and Nedbank offers 'Avo solar' and sustainability linked loans.
- Backup storage technologies provide benefits beyond loadshedding protection, including peak reduction/shaving to avoid demand charges, load shifting for time-of-use tariffs, and improved utilization of renewable installations. Li-ion batteries offer high efficiency and density but face lithium supply chain constraints and safety risks, while advanced lead acid batteries have lower upfront costs but shorter lifespans of 2-3 years.
- Several tax incentives are available to businesses, including Section 12B which allows a 100% depreciation allowance on qualifying renewable energy assets in the first year, and Section 12L which provides a deduction of 95c/kWh for verified energy efficiency savings.
- Implementation hurdles include a transmission and distribution grid not designed for new generation connections, which can lead to denied connections. Additionally, projects larger than 1MW typically face more legislative hurdles.
