RENEWABLE ENERGY WHEELING FOR SOUTH AFRICAN MANUFACTURERS
What is Discovery Green manufacturing wheeling?
Discovery Green is a renewable energy wheeling platform for South African manufacturers - from light assembly to heavy chemical and metal processing. Renewable electricity from large-scale wind and solar plants is delivered through the national grid at a price-certain rate.
Not all manufacturers have a flat baseload. Discovery Green models optimal solar-wind blends for each demand shape: roughly 23% solar / 77% wind for chemical plants, and 8% solar / 92% wind for metal processing. Every contract is shaped to match.
24-hour shift patterns
Every manufacturer has a unique consumption shape - continuous plants, three-shift processors, or seasonal lines. Discovery Green reads interval data to build a supply blend matched to the actual shift structure.
Solar + wind blend
The solar-wind mix is modelled against each manufacturer's production schedule. Heavy-process sites tilt towards wind; daytime assembly plants lean solar. The blend is shaped using the manufacturer's own data.
Three-shift cycles
Three-shift manufacturers consume power around the clock. Standard PPAs penalise off-peak under-consumption - Discovery Green's platform model absorbs that variation at portfolio level.
CBAM-ready scope 2
The EU's Carbon Border Adjustment Mechanism arrives in 2026. Green Guarantee delivers up to 100% renewable coverage with audit-ready Scope 2 documentation accepted by international buyers and CBAM auditors.
BUILT FOR DECISION MAKERS
Who manufacturing wheeling is built for
FOUR PHASES
How manufacturing wheeling comes together
Large businesses exploring renewable energy frequently find that the available options address only part of the problem.
Production schedule and Interval data submission
Submit 12 months of interval data and receive a customised proposal shaped to your actual shift patterns within 10 business days.
Product selection and manufacturing contract terms
Select Green Saver for cost-led decarbonisation or Green Guarantee for CBAM compliance, with contract terms agreed at this stage.
Solar-and-wind blend modelling
The optimal solar-wind blend is modelled against your production schedule, with the ratio shaped using your own consumption data.
Regulatory approvals and first renewable wheel
Wheeling agreements are concluded and from the first renewable wheel you purchase generation at CPI escalation with audit-ready Scope 2 documentation.
SIX CAPABILITIES
What manufacturers get with Discovery Green
Blend matched to production schedule
A 24/7 continuous chemical plant runs a different consumption shape from a single-shift assembly facility, and the optimal supply blend differs accordingly. Discovery Green's whitepaper publishes baseline blends per industry; the proposal builds on the manufacturer's own interval data to refine the mix further.
CBAM-ready scope 2 documentation
The European Union's Carbon Border Adjustment Mechanism is expected online in 2026 and threatens an estimated $2.8 billion of South African exports in the short term, particularly iron, steel and aluminium. Green Guarantee delivers up to 100% renewable coverage with the Scope 2 documentation pack that CBAM auditors are asking for.
P90 numbers for capital approval
Board-defendable. Manufacturers running multi-million-Rand annual energy bills cannot put nameplate-only projections in front of capital committees. Generation variability is modelled with P90 confidence intervals, weather and equipment degradation included, so the savings case survives technical and financial scrutiny.
THREE PRODUCTS
Discovery Green Manufacturing Pricing
Green Flex
40% Coverage
A starting position on the platform. Flat tariff per kWh, no time-of-use complexity. Energy Reserve mechanism reserves headroom to step up to Green Saver as the manufacturer's decarbonisation strategy evolves. Predetermined upgrade rates locked in from day one.
Green Saver
90% Coverage (70% Min)
The cost-led choice for manufacturers without immediate Scope 2 export pressure. Replaces around 90% of consumption with renewable supply, with a 70% minimum and headroom to scale to 100%. Highest cost saving in the product range. Flat discount on the active energy charge per kWh.
Green Guarantee
100% Coverage (up to 110%)
The CBAM-driven choice for manufacturers exporting iron, steel, aluminium or other carbon-intensive goods into the European Union. 100% renewable coverage with audit-ready Scope 2 documentation pack that CBAM auditors accept. The longer the contract, the smaller the premium.

Where Manufacturing Sits in the Discovery Green Range
Green Saver (90%, 70% min)
Replace ~90% of electricity with renewables at the highest cost saving.
Green Guarantee (100%, up to 110%)
100% renewable coverage with audit-ready Scope 2 documentation for CBAM compliance.
Ampli Energy (Demand Pooling)
Aggregates demand so smaller supply-chain operations can access wheeling.
THE PROOF BEHIND EACH
Why manufacturers choose Discovery Green over a direct PPA
The blend is designed around the production schedule
Most renewable suppliers sell what they have built. Discovery Green builds the supply blend around what the manufacturer actually consumes. The published blends in the Discovery Green whitepaper (chemical manufacturing 23% solar / 77% wind, metal processing 8% solar / 92% wind) are the baseline; the proposal refines further from interval data.
CBAM documentation is in the product, not bolted on
For manufacturers with European exports under CBAM scrutiny from 2026, Scope 2 documentation has to survive external audit. Green Guarantee's documentation pack is structured around CBAM auditor requirements, not built as an afterthought. Aggregated supply means Scope 2 evidence is not exposed to single-project underperformance.
Contract terms allow for shutdown weeks
Take-or-pay templates assume continuous demand. Manufacturing has annual shutdowns, line changes, and demand swings tied to commodity cycles or end-customer seasons.

FREQUENTLY ASKED QUESTIONS
Manufacturing FAQ
How does the solar-and-wind blend get matched to a production schedule?
The manufacturer submits 12 months of interval data. Discovery Green's platform reads the shift structure, weekend pattern, seasonal swings, and planned shutdown windows directly from the data. The optimal solar-and-wind blend is modelled against the production schedule. Heavy-process manufacturers tilt towards wind-heavy blends; daytime assembly plants take a more solar-weighted mix.
Does Green Guarantee actually satisfy CBAM auditors?
Green Guarantee's documentation pack is structured around CBAM auditor requirements. 100% renewable coverage with audit-ready Scope 2 documentation. Aggregated supply means Scope 2 evidence is not exposed to single-project underperformance. The documentation survives external review.
What happens during our annual planned shutdown week?
Annual planned shutdowns, line-change weeks, and seasonal production swings are written into the contract structure. Standard take-or-pay templates penalise under-consumption. Discovery Green's contracts allow for the manufacturing reality of off-weeks without triggering penalty exposure on the renewable supply commitment.
How much does manufacturing wheeling actually save?
Savings apply to generation costs, which represent approximately 45-55% of total electricity costs. Transmission and distribution charges remain unchanged. Pricing depends on consumption profile, product selection, and contract length. Longer contracts receive more favourable rates. A customised proposal based on the manufacturer's 12 months of interval data is delivered in 10 business days.
Why use Discovery Green instead of a corporate PPA with a single wind farm?
Aggregated supply across multiple plants and weather systems, anchored by 460MW of contracted capacity in Discovery Green's portfolio. No single project failure threatens the supply continuity built into the manufacturer's operating plan. Contract terms are written around production reality, with flexibility mechanisms that survive operational change.
How long from first conversation to renewable electricity flowing into the plant?
Ten business days for initial assessment. 60-90 days for detailed proposal with actuarial modelling. 6-12 months from signing to wheeling commencement, depending on regulatory approvals and grid connection requirements.
