Helios Nexus Energy Business Plan › Section 6 › Development Programme

Helios Nexus delivers its portfolio through five flagship projects,
sequenced to establish the trading platform and first generation early,
then scale generation, storage and regional expansion. Each project is a
discrete, financeable undertaking with its own grid, offtake and
SPV.

6.1 Sequencing logic

The sequencing is deliberate. Project Atlas Grid — the trading and
digital-energy-management platform — is established first (Year 2), at
modest cost, to build commercial relationships, data and licences ahead
of the generation coming online. Project Solaris (600 MW solar) delivers
first large-scale generation and cash flow by Year 3. Project Zephyr
(750 MW wind) adds profile diversification by Year 5. Project Titan (1.5
GW BESS) firms the portfolio and unlocks ancillary and arbitrage revenue
by Year 6. Project Infinity extends the platform regionally into the
SADC deficit markets in Years 7–10. Capacity reaches commercial
operation roughly two years behind capital commitment, producing the
revenue ramp modelled in Section 8.

6.2 Technology and delivery

Construction and completion risk is transferred to established EPC
contractors under fixed-price, date-certain turnkey contracts, with
independent-engineer certification gating lender drawdowns. Solar and
wind assets have 25-year-plus operating lives; BESS requires
augmentation over a roughly 12-year cycle, reflected in the depreciation
and capital assumptions.

6.3 The storage and flexibility strategy

Battery storage is the linchpin of the integrated model. 1.5 GW of
BESS does far more than arbitrage: it firms intermittent solar and wind
into dispatchable, premium-priced products; it captures the arbitrage
between low midday solar prices and high evening peaks; it provides
frequency regulation and grid-balancing services under emerging
ancillary-services markets; and it eases the grid-connection constraint
by smoothing output and reducing curtailment. As the Battery Energy
Storage IPP Procurement Programme and the four-hour-storage mandates in
recent bid windows demonstrate, the market increasingly values firm,
storage-backed capacity over raw energy — and the platform’s storage
layer positions it precisely for that shift.

Storage also underpins the trading division: with dispatchable
capacity, the trading desk can offer firm delivery and manage portfolio
balancing risk far more effectively than a trader relying on
intermittent third-party supply. This is a concrete example of the
integration thesis — storage makes both the generation and the trading
businesses more valuable than they would be apart.

6.4 Generation asset strategy and yield

The generation portfolio is built for complementarity and yield.
Solar (3 GW) provides the lowest-cost energy with a midday-peaked
profile; wind (3 GW) delivers a higher capacity factor and an
evening-weighted profile that complements solar and better matches
demand; and storage (1.5 GW) shifts and firms both. This
three-technology mix produces a smoother, more dispatchable aggregate
output than any single technology, improving both the contracted-PPA
proposition and the trading desk’s ability to offer firm delivery.

Yield optimisation is continuous: the asset-management function
monitors performance against resource, manages BESS dispatch to capture
arbitrage and ancillary revenue, minimises curtailment losses through
the trading and wheeling routes to market, and schedules augmentation
and refurbishment to preserve output over the 25-year-plus asset lives.
This operational layer is where a platform operator adds value beyond a
passive asset owner, and it underpins the yield assumptions in the
financial model.
