Product · Data Centre Flex

Turn your data centre into a flexible grid asset

Maximise your compute envelope. Arbitrage energy. Earn from grid services.

The Opportunity: Skip the Queue

Fit your campus into the headroom that's already there

Plug into existing grid headroom — no new interconnection

Most grids run well below peak most of the year. Connection queues are years long precisely because applicants are sized for their own peak, not the grid's. By committing to a flexible operating envelope — shifting deferrable workloads, dispatching onsite storage and generation, gracefully shedding non-critical compute during the few hours of system stress — your campus fits inside the capacity that already exists. Energise sooner, scale faster, and keep critical inference at six-nines while the optimiser handles the trade-offs in real time.

And while you're flexible — two more revenue lines

Arbitrage energy

Charge onsite BESS, pre-cool thermal mass, and shift flexible compute into low-price intervals. Discharge or curtail when wholesale prices spike. Every megawatt-hour bought is an optimisation decision, not a fixed PPA draw.

Earn from grid services

Offer regulation, contingency and fast-frequency response into the ancillary service markets your grid operator runs. Your aggregate flex — BESS, HVAC setpoints, compute shedding, onsite generation — becomes a bid stack.

Your campus, in Modelica

Your engineering team — or a specialist Modelica consultancy — describes the physics of your site: cooling topology, thermal inertia, compute-to-power curves, generator dynamics, interconnect constraints. Because Modelica is open and standardised, this model is yours: portable, inspectable, and reusable for design studies, commissioning and digital twinning.

Our market value-stacking layer

On top of that model, we apply the co-optimisation and bidding logic honed on utility-scale BESS, hybrid renewable portfolios and HVAC demand-response in the NEM, ERCOT and European markets. Day-ahead, intraday, real-time, ancillary services, capacity mechanisms and tolling — all stacked together, every bid aware of your physical constraints.

Don't have a Modelica model yet? We'll help you scope one and introduce you to partners who specialise in data-centre-scale modelling. Already have one? We plug in.

One Modelling Language for Every Asset

From GPU racks to SMRs — described in Modelica, optimised together

A data centre is not a single asset. It is a portfolio — compute, cooling, storage, generation, and a grid connection — with coupled dynamics and coupled economics. Modelica is the open, equation-based modelling language used across aerospace, automotive and energy to describe exactly this kind of multi-domain physical system. A global community of modelling experts and engineering firms already builds Modelica libraries for buildings, power systems, HVAC, thermal storage and process plants.

Markets We Cover

Wherever your racks run, we bid them into the right product

Australia · NEM

5-minute co-optimised energy and FCAS (raise/lower, regulation, contingency across all timescales). Wholesale Demand Response mechanism for load-side flex. Strong precedent for behind-the-meter assets bidding as scheduled loads.

Texas · ERCOT

Post-RTC+B (December 2025), energy and all five ancillary service products clear together every 5 minutes. Controllable Load Resources and Load Resources participate directly. The queue is full — flex is the interconnect fast-lane.

Europe

Day-Ahead, Intraday Auctions and Continuous, FCR, aFRR and mFRR across the interconnected zones. Capacity mechanisms and interruptible-load schemes in the UK, France, Germany, Italy, Spain and the Nordics.

How the Optimiser Plays

Co-optimised, not siloed

Every dispatch decision is made together: which GPUs run, which chillers pre-cool, which battery cells charge, which peakers stand warm, which ancillary products to bid — all reconciled in one pass against the site's physical constraints.

SLAs come first

Tenant SLAs, six-nines availability and regulatory commitments are respected absolutely. The optimiser only offers flex the site can actually deliver — never at the cost of uptime.

Probabilistic forecasts

Prices, renewable generation and workload demand enter as ensembles, not point estimates. Risk-aware bidding that holds capacity for high-value tail events rather than over-committing to expected outcomes.

Open-core, auditable

Built on Modelica and the open-source LF Energy RTC-Tools framework. Every decision is explainable; every model is inspectable.

Built on
Modelica LF Energy RTC-Tools

Modelica is the open, equation-based modelling language used across aerospace, automotive and energy to describe multi-domain physical systems. RTC-Tools is an LF Energy project battle-tested since 2015 across water, hydropower, BESS optimisation, HVAC and thermal storage (TES), and renewable portfolios worldwide. We combine them so every asset on your campus — compute, thermal, storage, generation — is a first-class, auditable decision variable.
