Peak-power tariffs are a growing line in your operating costs. We shave the peaks for you, with no investment required.
Lower the peak tariff.
The battery is financed, deployed and operated for you on your grid connection. You see lower operating costs from day one, without having to learn battery systems, balance responsibility or flexibility markets. We do the work. You see the result.
Peaks for hours. Cost all year.
Demand charges and peak-power tariffs price your highest drawn capacity over a period. A single charging event, a compressor starting, a chiller running in summer. That is enough to set your tariff bracket. It then stays in place, month after month.
In March 2026 the Swedish government dropped the mandatory rollout of new peak tariffs aimed at residential customers. Demand charges for commercial customers, low-voltage N4 connections and high-voltage are not affected and remain in force. They have existed for years, and they are not going away. For you, this is not a temporary cost.
We size. We deploy. We optimise.
The Sourceful Energy Vault sits on your existing grid connection. We optimise the whole picture: behind the meter the battery shaves your peaks, in front of the meter the same capacity works the flexibility markets. It is the combination, our multi-market optimisation, that delivers the most value per installed kWh. And the solution does not stop at the battery, the same control can bring in other large loads such as fast chargers or process load and optimise them together. Backup power for critical loads is available as an add-on.
We assess
We analyse your load profile, fuse rating and grid connection. We then size the battery to your operating profile, not to a standard catalogue.
We deploy
The investment is funded for you. Nothing sits on your balance sheet. You do not negotiate balance-responsibility contracts and you do not procure electricians.
We optimise
Around the clock we optimise the whole picture: the demand charge behind the meter and the flexibility markets in front. The multi-market optimisation is what maximises the value. You see lower grid charges on the invoice.
Fully managed. So you can focus on your business.
Owning a battery in 2026 means handling four things: sizing, financing, operations and optimisation. We take all four.
- 01Design and sizing of battery systems
- 02Approvals and regulatory compliance
- 03Real-time control behind the meter
- 04Bids into ancillary services and the spot market
- 05Contracts with the balance-responsible party
- 06Maintenance, insurance and warranties
- 07Metering, data collection and settlement
Two ways to do it. Both lower the peak cost.
Most partners take the zero-capex path, where the battery is financed and fully operated for them. For property owners who want the battery on their balance sheet, there is an alternative. You own, we operate, and you collect two revenue streams: predictable rent from us and lower grid costs directly on the invoice.
Zero capex
- €0 investment
- Financed, deployed and operated for you
- Lower peak tariff from day one
- Nothing on your balance sheet
- Shortest time to result
Own it yourself
- You invest in the battery
- We operate and optimise
- Predictable rent from Sourceful
- Lower grid cost directly on the invoice
- Asset on your balance sheet with stable return
The mix between rent and grid-cost savings depends on the property's consumption profile. We model the split during qualification.
Better NOI. Without investing.
Peak-power tariffs are a growing line in your property's operating costs. EV chargers in the garage, heat pumps, ventilation and cooling create peaks that last hours but cost you all year. We shave them.
- ·Garage EV charging pushes monthly peaks up
- ·Winter heating and ventilation run at the same time
- ·A single peak sets the tariff bracket for months
- ·Peak charges flow straight to NOI
At a commercial low-voltage customer (N4) in SE4 we shave more than 100 kW for several hours, exactly when the grid costs the most. We run the battery at the moments that deliver the most value to your site.
Lower demand charges
We shave the monthly peak by 100+ kW for several hours, exactly when grid costs are highest.
Improved NOI
Lower grid costs lift NOI. The recurring saving capitalises into property value at the market's yield.
Zero investment
No capital to tie up. Nothing on the balance sheet. The battery is financed and operated for you.
Zero complexity
We handle everything operational: design, permits, balance responsibility, operations and optimisation. The contract details we walk through during qualification.
Backup power as add-on
The battery can be equipped with a backup-power function. Tenants and critical systems stay running during a grid outage.
Demand charges are permanent. We shave them permanently.
Industry has paid demand charges for decades. What is new in 2026 is that battery storage as a service is a mature product. You do not have to finance, size or operate anything yourself.
- ·Compressors, ovens and process loads create predictable peaks
- ·Demand charges are priced on the highest draw, not on the average
- ·Owned peak shaving needs engineering hours and capital you would rather spend on production
A manufacturing site with variable load benefits the most. The peaks are there, but they are not constant. We calibrate the system to your operating profile and seasonality.
Peak shaved
The battery shaves predictable process peaks in real time. The meter records a lower peak, which is what the demand charge is based on.
Freed grid capacity
Peaks that previously needed an upgraded connection now fit. New load lands inside the same subscription.
Focus on production
We handle the energy complexity. Your operations team does not need to learn the rulebook for balance responsibility.
Backup power as add-on
An add-on for critical processes that cannot tolerate unplanned outages.
Electrify the fleet without raising your demand charge.
A depot with five electric trucks charging at the same time draws as much power as a small data centre. The demand charge grows with the peak. We shave it.
- ·Fast-charging heavy vehicles creates megawatt-scale peaks for several hours
- ·A higher demand charge eats margin in an already pressured industry
- ·Waiting for a new service line is not an option when the transition is already underway
A depot with electrification underway or planned, where several trucks charge between routes, is our direct target. We size the battery to your schedule.
Charge more vehicles
The same connection holds more concurrent charging. The battery carries the peak, and we can bring the chargers into the same optimisation.
Stable cost base
Predictable grid cost as the fleet grows. You can price against the haulage rate, not the tariff.
No extra grid investment
Skip expensive service-line or transformer upgrades. We solve it behind the meter.
Backup power as add-on
During a grid outage the depot can keep chargers and refrigerated zones running.
Peaks in the barn cost you all year.
Milking robots, refrigeration, feed processing and electrified tractors. The load profile of a modern farm has shifted fast. The demand charge has not changed at the same pace.
- ·Milking robots with synchronised cleaning cycles create daily peaks
- ·Feed processing and cooling run at the same time during summer heat
- ·Investing in your own battery is the wrong economics for a farm balance sheet
Farms that produce milk or meat with electrified peripherals. We size the battery to your annual profile. Summer cooling and winter heating weigh differently.
Operational savings without investing
Lower grid charges without tying up capital or borrowing against the farm.
Headroom for further electrification
Freed capacity on the connection makes room for charging, heat pumps and electric machines.
Fully managed
We operate and optimise. You run the farm.
Backup power as add-on
Milking robots, cooling and ventilation can keep running during a grid outage.
