Unlock More Value from BESS and Generation Portfolios with Interrogatable Optimisation

Real-time optimisation for utility-scale, co-located, and portfolio-based systems. Open core. Interrogatable. Proven to perform.

PortfolioEnergy delivers high-performance optimisation software for utility-scale batteries, co-located sites, and generation portfolios. Designed to work with your existing systems, our transparent, interrogatable solution helps you unlock greater value — even in complex physical and virtual offtake arrangements.

Why Optimisation Matters

Optimisation is no longer optional; it's the key to staying competitive.

As energy storage becomes the predominant form of firming renewable energy, the ability to maximise revenue depends on how effectively you optimise your portfolio of generation assets across all value streams.

The markets that incentivise battery storage will continue to evolve. A scalable optimisation solution, one that operates at the asset, portfolio, and market level, is essential to maintaining a competitive edge and achieving long-term sustainability in an increasingly complex energy landscape.

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 and 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, our platform provides:

Transparent, open-core optimisation logic

Direct integration with your systems via REST API

The flexibility to interrogate and adapt the system over time

We're not just another locked-down SaaS provider. We're a partner in moving the market toward open, auditable, and high-performance optimisation that benefits your bespoke generation portfolio and risk management posture.

Built on RTC-Tools and Modelica

We built our optimiser on RTC-Tools and Modelica, open-source technologies proven globally for complex scheduling and energy management across water and energy sectors.

Our system delivers:

  • REST API integration for fast onboarding
  • Interrogatable logic with full visibility into how optimisation decisions are made
  • Support for deterministic and probabilistic forecasts
  • Risk-adjusted optimisation for volatility and price spike positioning
  • Scalable optimisation across asset, portfolio, and market levels
  • Seamless fit into your tech stack with the ability to create custom dashboarding in your existing interfaces.

This is not a black box. It's an open optimisation framework you can interrogate, adapt, and build on, and it's already proven in the world's most complex energy and water systems.

Built for transparency. Proven in practice. Ready to test it in your environment?

What Makes Us Different

Not all optimisation platforms are created equal. Here's what sets us apart:

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

In high-volatility markets, clients have seen more than 100% uplift compared to the status quo. We're focused on 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.

PortfolioEnergy may be new, but our team has spent the past 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

  • Submit Historical Data
  • Receive Custom 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.
