Your EMS runs the site. We run the economics.
An energy management system keeps your site safe and balanced. Companion.energy ties every kWh to its euro impact and steers your flexibility across markets. Most power pioneers use both.
Our energy expert Erik can tell you all about it
Local control or financial optimisation
Both matter. They answer a different question. Your EMS asks what the site needs right now. Companion.energy asks what every kWh is worth, and when.
| Aspect | A typical EMS | Companion.energy |
|---|---|---|
| Main job | Local power balancing, asset protection and energy monitoring | Financial optimisation across assets, sites and markets |
| Scope | One site or one system | Every site, meter, contract and market signal in one live view with PRISM |
| Market value | Rarely in scope | Day-ahead spreads, imbalance exposure and aFRR balancing, captured by PROPEL |
| Peak shaving | Against local limits | Against capacity tariffs, coordinated across sites |
| Cost view | kWh and kW | Every kWh tied to its euro impact, across commodity and non-commodity charges |
| Forecasting | Focused on what happens on site now | Machine learning that blends weather, markets and your operations |
| Hardware | On site | Cloud platform, no extra hardware. Works with your EMS |
Built to protect the site, not to earn from it
An EMS is excellent at what it was built for. The financial and market layer is where most EMS roadmaps stop.
Kilowatts, not euros
An EMS sees power and energy. It doesn't tie every kWh to its actual cost across contracts, tariffs and market prices.
One site at a time
Each site balances itself. Flexibility across your portfolio stays uncoordinated.
Markets out of scope
Day-ahead spreads, imbalance exposure and balancing revenue rarely reach the control logic.
Reacting, not anticipating
Local control responds to what happens now. Price spikes are handled after they hit.
Companion.energy helps us make sure all energy assets work together intelligently.
What Companion.energy adds
Financial depth
One live cost view across sites, contracts and market prices, so finance and operations work from the same numbers.
Multi-market optimisation
Day-ahead spreads, imbalance exposure, aFRR balancing and peak shaving against capacity tariffs, as one decision.
Multi-site coordination
Flexibility steered across your whole portfolio, not one site at a time, within the rules you set.
See first.
Steer second.
Prism gives every site a live cost view. Propel forecasts markets and dispatches your flexible assets, ahead of every price move.
50-80% less manual work and real-time energy costs across every site
Prism connects every meter, every contract and every market signal into one live view. Finance and operations work from the same numbers.
Real-time visibility across every cost driver
Cuts monthly data pulls and cross-system reconciliations.
Sharper contracts. Smarter hedges.
Cuts the gut-feel calls in volatile markets.
Live budget tracking against actual exposure
Cuts month-end P&L surprises with continuous truth.
Forecasts that anticipate, not react
Machine learning blends weather, markets and your operations into every forecast.
10 to 30% lower energy costs. Multi-market dispatch across every flexible asset
Propel forecasts every market ahead of time and schedules your assets accordingly. Generating, storing or using energy to drive savings and extra revenue.
Multi-market dispatch, autonomously
Captures imbalance, ancillary and arbitrage value spreadsheets can't deliver.
Anticipates market moves ahead of time
Schedules dispatch before price spikes hit, not after they pass.
Orchestrates flexibility as one system
Solar, wind, batteries and process flexibility steered together.
Within your rules
Aligned with operational constraints. The decision and its outcome stay with you.
Your EMS and Companion.energy, better together
Companion.energy is cloud-based optimisation for your local energy management system. Your EMS keeps balancing power and protecting assets on site. We add the market and financial layer on top, within the rules you set.
Do I need to replace my EMS?
No. Companion.energy works with the systems you already have. Your EMS keeps doing what it does well on site, and we add the market and financial layer on top.
Where does the EMS stop and Companion.energy start?
An EMS is excellent at local power balancing, asset protection, and energy monitoring. Companion.energy goes further into financial depth and multi-asset, multi-market optimisation: capturing day-ahead spreads, managing imbalance exposure, optimising peak-shaving against capacity tariffs, coordinating flexibility across sites, and tying every kWh to its actual euro impact. That is where most EMS roadmaps stop and where ours begins.
Do I need to buy hardware?
No. Companion.energy is a cloud platform. It connects to the meters, systems and assets you already have.
