We deliver fully integrated rooftop and ground‑mount photovoltaic (PV) systems, combined with high‑cycle battery energy storage systems (BESS) and optional generator (genset) integration to provide a resilient, flexible, and future‑ready energy solution. Systems can be configured to support grid‑tied, hybrid, or islanded operation, with genset integration enabling black‑start capability and long‑duration energy cover during extended outages or grid instability. Each solution is engineered and optimally sized based on a detailed assessment of your tariff structures, demand and load profiles, operational cycles, and grid constraints, ensuring maximum economic benefit and system performance. By intelligently balancing on‑site generation, stored energy, grid supply, and backup generation, we enable seamless transitions between energy sources and uninterrupted power availability.
Wheeling | Renewable Energy
Power Purchase Agreements
We provide wheeling and Power Purchase Agreement (PPA) solutions, enabling clients to procure clean energy from Independent Power Producers (IPPs) and consume that energy across South Africa’s transmission and distribution networks. Our solutions are structured in accordance with the latest NERSA wheeling rules and applicable municipal wheeling frameworks, where available. The Green Co manages the end‑to‑end wheeling process, acting as the single point of coordination between generators, offtakers, Eskom or municipal distributors, and regulators. This includes the commercial, technical, and regulatory components required to ensure compliant, bankable, and operationally reliable wheeling arrangements.
EMS & Optimisation
At the core of our solution is an Energy Management System that schedules batteries, shifts load, and arbitrages TOU tariffs — ensuring your business always uses the lowest‑cost energy available at any given time. The EMS continuously schedules batteries, shifts loads, and switches energy sources automatically to ensure the lowest‑cost, most efficient energy mix at every hour of the day, supported by live monitoring and reporting.
This delivers a holistic energy production and utilisation strategy that:
✅ Minimises cost per kWh in real time
✅ Maximises value from batteries and generation assets
✅ Reduces reliance on peak‑tariff grid power
✅ Improves resilience during outages and load shedding
✅ Delivers the best financial, social, and environmental benefits
Through automated integration of solar PV, batteries, grid supply, generators, and other energy production mechanisms, the system dynamically switches to the optimal energy source based on cost, availability, and performance.
You don’t just install energy assets — you operate a smart, automated energy ecosystem.
Compliance & RECS
At The Green Co, we believe that every step towards a greener future is a meaningful one. In South Africa—where access to clean power can be constrained by grid limitations and infrastructure—International Renewable Energy Certificates (I‑RECs) play a critical role in enabling organisations to take immediate, credible action towards sustainability.
We provide Renewable Energy Certificates (RECs) as a foundational component of our sustainability offering, enabling organisations to credibly and transparently demonstrate their commitment to renewable energy.
Every time a renewable energy facility generates one megawatt‑hour (MWh) of electricity, it also generates one Renewable Energy Certificate (REC). This certificate represents the environmental attributes and benefits associated with that unit of renewable electricity.
A REC is a tradable, non‑physical commodity that provides verified proof that electricity was generated from a renewable source such as solar, wind, or hydro. While the physical electricity flows into the grid, the REC can be transferred independently and claimed by the end user.
In South Africa and many international markets, these certificates are issued under recognised schemes such as I‑RECs, ensuring credibility, traceability, and avoidance of double counting.
By purchasing RECs, a company is entitled to claim the use of renewable energy within its operations, even where on‑site generation or direct access to renewable power is not feasible.
REC demand:
A Renewable Energy Certificate (REC) represents the environmental benefit of one megawatt‑hour of renewable electricity. By purchasing RECs, organisations can credibly claim renewable energy usage, support the growth of clean energy markets, and progress their ESG and sustainability goals—without installing generation assets on site.
Our Process
“Profitable sustainability” is not a slogan — it’s an engineering and contracting discipline. We bring the finance, the tech stack, and the compliance rigor to make it real for South African businesses.
✅ Phase 1 — Diagnose & model (2–4 weeks) Data acquisition (interval metering, tariffs), grid‑connection constraints, load segmentation (critical vs. flexible), compliance review, and financial model with multiple capex/opex options.
✅ Phase 2 — Portfolio design (4–8 weeks)
✅ Phase 3 — Build & integrate (8–20 weeks) EPC with quality‑assured BOS and certified installers; commissioning, acceptance testing, and EMS tuning for TOU arbitrage and outage response
✅ Phase 4 — Operate & optimise (ongoing) Performance guarantees, preventive maintenance, monthly savings and carbon reporting, and renegotiation of PPAs as market rules mature (e.g., day‑ahead market go‑live).
✅ Phase 5 - Integration with other Energy Production Mechanisms and Monitoring System for low cost energy usage, monitoring and visibility at all times.

The State of Energy in South Africa (2025 - 2026)
- Structural reform is reshaping the market. The Electricity Regulation Amendment Act (effective 1 Jan 2025) begins South Africa’s move to a competitive power market with a Transmission System Operator and market code on the way. Eskom’s next-stage unbundling (GenerationCo, NTCSA, DistributionCo/NEDCSA, Eskom Green) was approved in Dec 2025, with reforms intended to enable competition and new capacity.
- Load‑shedding has eased but risks remain. Eskom reported long stretches with minimal or no load‑shedding in 2025, supported by improved Energy Availability Factor and lower diesel burn; however, adequacy from 2026 depends on grid access and long‑term capacity additions.
- Rooftop solar has surged. Private behind‑the‑meter PV is now estimated above 7 GWp, with Gauteng leading; embedded PV materially flattens daytime demand and has grown >400% since 2021. Wheeling is going mainstream. National rules for third‑party network charges (2025) and municipal frameworks (2025) unlock direct PPAs and multi-site energy flows across networks.
- The City of Cape Town has implemented bilateral wheeling and is piloting pooled wheeling. Embedded generation rules: Grid‑connected SSEG must be registered (sub‑100 kW with the distributor; ≥100 kW with NERSA); purely off‑grid is exempt.
- Tariff pressure persists. Regulated increases and network cost rebalancing continue to drive C&I customers to self‑generation, storage, and wheeled supply.
