Strategic Report
This has been a landmark year for the Company, defined by increased
scale, delivery and innovation. We have more than doubled our
operational portfolio capacity, reaching nearly 1 GWh across
five energy systems. We have secured $165 million in long-term
contracted revenue and have strengthened the cash position with
additional funding from two high-quality lenders and monetisation of
all Investment Tax Credits for the Company’s recently energised US
assets. Going forward this increase in revenue-generating capacity
will be complemented by a declining cost base, supported by a
revised fee structure based on market capitalisation and net asset
value. Our diversified strategy and active approach has ensured that
we continue to generate best-in-class revenue.
Our internal, purpose-built platform spanning investment,
procurement, asset management, and trading is a specialisation
that has unlocked international expansion and gives us excellent
growth opportunities across the portfolio. While others have focused
on limiting the lowest bounds of their revenue generation, we have
focused on achieving the highest revenue across the sector. To further
support this, we have developed a bespoke AI-driven optimisation
platform, uniquely specialised for BESS assets, which has yielded
double-digit outperformance against industry benchmarks.
As the global energy transition accelerates, our diversified,
data-driven, and disciplined approach ensures that we remain at the
forefront of the utility-scale BESS sector.
Technology-Led: Next Generation Asset Management
Our technology-driven approach to asset management is a
cornerstone of our operational strategy; designed in-house to deliver
real-time visibility, predictive insights and performance optimisation
across the fleet. Over the past year, we have significantly advanced
this capability. We have integrated with a leading battery analytics
platform, enabling 24/7 monitoring and daily safety diagnostics
across onboarded projects. This has materially improved the safety
profile of the fleet, with early warning and state–of–the–art safety
indicators now embedded into daily operations. In parallel, we
have executed a framework agreement with a second platform to
standardise data capture and visualisation across all assets, ensuring
consistency and comparability at scale.
At the heart of this is our bespoke, cloud-based platform, which
is currently under development. This will bring asset visibility,
monitoring and alerting in a single interface. The system is designed
to support automated monitoring, predictive maintenance and
real-time alerting. It enables us to manage risk more effectively,
reduce downtime, improve availability across a geographically and
technologically diverse portfolio and make informed decisions
about who we choose to work and have ongoing partnerships with.
In addition, this sophisticated approach to asset management
has been recognised and has resulted in a material reduction in
insurance premiums. As we continue to scale, this system will be
key to maintaining our >95% availability with an approach to safety
that reduces premiums and ensures every megawatt under our
management is optimally maintained and exploited.
GSET: A Proprietary Trading Platform Designed to
Perform
Gore Street Energy Trading (GSET) is our in-house optimisation
platform; it is purpose-built for battery storage and engineered to
outperform. Unlike third-party tolling or floor structures, GSET is
fully owned and operated by Gore Street, giving us complete control
over strategy, execution and ultimately profitability. The platform is
built on a proprietary software stack that includes neural networks,
multivariate regressions, and fundamental forecasting models. These
models are continuously back-tested and tuned to reflect market
dynamics, enabling real-time re-optimisation of assets based on price
signals and the asset’s state of charge, as well as risk-adjusted return
profiles.
It is this dynamic capability to optimise across the full range of
ancillary services, wholesale trading, and the balancing mechanism
that has driven the outperformance of our software, exploiting both
positive and negative pricing periods, and the profit-maximising
approach based on often-overlooked asset-specific factors such as
degradation and warranty considerations. Since its launch, GSET has
consistently outperformed the Modo benchmark and now manages
68% of the Company’s GB portfolio. The platform is built to cover
all markets in which the Company operates, with the onboarding of
some of the Company’s assets in Texas expected in the near term.
The GB market averaged c.£72,400/MW/yr, this is materially lower
than the Company’s GSET managed portfolio, which achieved
c.£81,900/MW/yr on an annualised basis (inclusive of capacity
market contracts for the period from December 2024- March 2025
to account for GSET’s onboarding schedule), re-emphasising the
value of internally managing assets. Internalising optimisation is
critical to this asset class, unlocking specialist commercial strategies
to maximise revenue while considering the long-term performance
of the asset. A range of management approaches are seen across
the sector, especially seen in the approach to the stacking of both
contracted and merchant revenue streams. The value from energy
storage assets is multifold, providing grid security, and stabilising
services, all of which support the increasing intermittency associated
with renewable penetration. As an active manager, capturing this
volatility is fundamental to unlocking superior returns.
Declining Capex: A Structural Tailwind for Growth
The sector is undergoing a structural reset in capex costs, driven
by a convergence of oversupply, falling commodity prices, and
rapid technological advancements. Lithium prices, for instance, are
now 75% below their 2022 peak, and battery pack costs declined
a further 20% between 2023 and 2024 alone. This has had a
dramatic effect on project economics. Until recently, longer-duration
systems in key markets, such as GB, were prohibitively expensive
to enhance returns. However, the declining trend now enables the
development of longer duration systems at a lower marginal cost.
This capex trend is not just a cost reduction; it is also a tailwind
for growth. As the cost of incremental capacity decreases at an
unprecedented rate, our ability to retrofit existing assets and
deploy capital into lucrative and portfolio-accretive opportunities
