For battery owners, developers & aggregators worldwide

Buy the algorithm, keep the strategy yours

Every part of a battery trading operation is a choice between building and buying: price and generation forecasts, market access and connectivity, asset telemetry, dashboards and reporting — and the optimisation algorithm that decides what to bid, where, and when. Most of these you can assemble from partners you already work with, or already own.

The algorithm is the hard part. Building it from scratch commits a team of specialists to a year or two of development — and most still fail to catch the mature algorithms they're up against, then revert to selling their flexibility to the market anyway: the very outsourcing they set out to avoid. The gap between competitive and best-in-class is exactly where a battery's margin lives.

And it is never finished. Markets, rules and competitors keep moving, so the algorithm has to keep moving with them — a permanent responsibility, not a project. Keeping it competitive takes a dedicated team for the life of the asset, and expertise concentrated in a few people walks out of the door with them.

It makes far more sense to start from a mature base. We've spent 11 years building ours on the open-source RTC-Tools foundation, and we run it live across 3 continents. You keep your forecasts, your desk, your market relationships, your brand — we provide the engine.

Then you make it yours. You configure the optimiser to your own business objectives, with portfolio-level risk appetite the main lever: how hard to chase market spreads against how much downside to carry. Those are the only true differentiators in a trading strategy — and they stay entirely in your hands.

Even with a team, catching up is hard

The hardest value to capture is the last slice — and it's the slice that decides a battery's returns. A team building from scratch can take years to get there, and the gap only widens.

A modest uplift in revenue is a much larger uplift in profit: the last slice lands almost entirely on the bottom line. The break-even level shown is illustrative — it depends on capex, financing and the market.

Organisations that self-build typically take 1–2 years to recognise they can't catch up, then revert to the market — burning cash and foregoing revenue through what may be the highest-spread years of the asset's life.

Meet PortfolioEnergy

What if your optimiser wasn't a mystery but a strategic asset you control?

Battery Energy Storage Systems (BESS) play a critical role in delivering firm, reliable power supply as the electricity sector transitions to renewables, but without accurate modelling of each generation asset and its constraints, their potential is limited. As more BESS projects are co-located with solar and wind, optimisation becomes more complex. These multi-asset sites must navigate control and network limitations while participating in multiple energy markets simultaneously.

That's where PortfolioEnergy comes in.

We deliver a high-performance optimisation layer that models each asset in real time, captures value across all relevant markets, and integrates seamlessly with your existing tech stack. Whether you're a trader aiming to capture volatility, a developer seeking to manage complex offtake arrangements, or an aggregator managing distributed fleets, the platform fits your operation.

Why PortfolioEnergy Outperforms Black-Box Solutions

Unlike proprietary "black box" solutions, our open-core approach lets you see and verify every decision:

Open & Interrogatable

See what's driving every recommendation. Our software is fully auditable, flexible, and ready to evolve with your strategy.

Proven Track Record

Our optimiser has delivered results for national water infrastructure, hydro assets, and thermal storage, and is now live for BESS across Australia (NEM), the US (ERCOT), and in Europe.

Revenue Uplift You Can Measure

Our uplift is measured and published — see our 2025 German and Australian BESS performance reviews. Real-world results, not hypothetical gains.

Built for Integration

Use your existing technology stack, from bidding to forecasting, and slot our optimiser into the middle. We also support forecasting inputs and telemetry integration where needed.

Step-by-Step Engagement

Start with a proof of concept pilot to validate our outperformance, move to shadow testing, and scale to live operation, with each step built around performance thresholds.

Strategic Alignment

We're here to move the market to open-core optimisation, delivering end-to-end, bankable solutions that realise the full value stack for BESS.

Innovation You Can Build On

We've been moving the needle in mathematical optimisation and publishing our innovations in peer-reviewed academic journals. But we don't stop at theory: We lead by maturing and adopting these innovations in practice.

We continuously benchmark against competing solutions, staying ahead through capabilities like nonlinear price elasticity modelling and bid/offer co-optimisation. On the basis of our open-source stack, we create bespoke optimiser solutions tailored to your specific needs.

We offer a market-leading optimiser — no less, but also no more. You stay in control of all data feeds, constraints, customer and market interface, and asset dispatch.

Proven Performance, Global Reach

Our battery storage optimisation platform is already delivering measurable uplift for utility-scale battery operators across the world.

We help clients capture additional value through energy storage dispatch optimisation, including arbitrage and price spike positioning, even under uncertainty and imperfect forecasts.

Our Story

Innovation grounded in experience; transparency backed by trust.

Our team has spent more than a decade leading optimisation innovation across energy and water markets. Founded by former leaders at Shell Energy, Deltares, KNMI, and ERM Power, our work has powered major infrastructure assets, and we have advised global energy clients.

Bringing Decades of Success to the Energy Sector

In 2015, our team began developing RTC-Tools, a powerful open-source optimisation platform for managing dynamic energy pricing in the water sector. Today, it is used globally to optimise water pumping, drainage, hydro, and pumped hydro systems. Over the past five years, we've adapted this capability for the energy sector, with a focus on individual and co-located BESS optimisation across three continents. Combined with Modelica for physical systems modelling of each BESS asset, our platform now supports:

  • Dispatch optimisation of individual and co-located BESS assets
  • Coordination across portfolios
  • Market-level interaction for maximum value

Flexible Models, Built for Growth

We offer clients the ability to license our latest models or receive asset steering via API under a subscription service. But more than that, we work with clients to build internal capability. Our subscribers can establish their own test environments and modify the optimisation logic as they evolve.

Ready to See the Difference?

Whether you're in early scoping or already running live assets, we'll work with you to deliver a measurable uplift in value.

Here's how we help you go from test to results

  • Run Backtest
  • Run Live Shadow Pilot
  • Go Live and Capture Value

We work closely with your team to support onboarding, telemetry connections, and data forecasting inputs, offering light-touch or hands-on guidance as needed.

Let's uncover the value hidden in your data. Discover what's possible when optimisation is open, interrogatable, and proven.
