About the system
What is spotEQ PeakGuard?
PeakGuard keeps the site's demand peaks down, so the capacity charge (effektledd) in your grid tariff is no higher than it needs to be. It plans in the cloud, with a new plan every 15 minutes for the next 48 hours, and controls on site from a unit in your electrical cabinet that reads the meter every second. It stays within the limits set at installation. PeakGuard moves load out of the peaks, for example from EV chargers, hot water, heating and ventilation. You follow the site in the PeakGuard app. More about PeakGuard.
Who is PeakGuard for?
Small and medium-sized businesses in Norway whose grid tariff has a capacity charge. Typical customers are grocery and retail, warehouses, cold stores and workshops, hotels and office buildings, and agriculture. PeakGuard does most when the peaks come from equipment that can be controlled or can wait, such as hot water, heating, ventilation and EV charging. PeakGuard is built for Norwegian tariff models, price areas and meter data from Elhub.
How can PeakGuard lower a business's electricity costs?
Above all by keeping demand peaks down in the hours that set the capacity charge in the grid tariff. PeakGuard does this by moving flexible load out of the peaks and, where needed, by using a battery. A battery can also charge when the spot price is low and supply the building when it is high, and it can cover short peaks from new equipment, so you may avoid a larger grid connection and the connection fee (anleggsbidrag) that comes with it.
What is the capacity charge, and why is it so expensive?
The capacity charge is the part of the Norwegian grid tariff (nettleie) that is set by your demand peaks, not by how many kWh you use. Most grid companies use the average of the three highest hourly values in the month, so a few bad hours can decide a large part of the bill for the whole month. Those are the hours PeakGuard keeps down.
Do we have to buy a battery?
It depends on the site. The easiest first step is often to move load out of the peaks. PeakGuard controls hot water, heating and ventilation through the building's control system (SD-anlegget), and warns before a new peak is set, so your staff have time to act. In the site analysis you get advice on load you can shift yourself, such as staggered start-up, timers and pre-heating. PeakGuard can also control EV chargers, and other process loads are assessed per project. A battery is for sites where moving load is not enough, and the site analysis shows what your site needs.
Can PeakGuard control EV chargers, hot water or ventilation?
Yes. Today PeakGuard controls EV chargers, and hot water, heating and ventilation through the building's control system (SD-anlegget). Cars charge in the cheapest hours without setting new peaks, and get the energy they need by an agreed time. PeakGuard also controls the battery we supply. Other process loads are assessed per project. PeakGuard also warns before a new peak is set, and the site analysis gives you advice on load you can shift yourself.
Can PeakGuard move load to hours with low electricity prices?
Yes. PeakGuard plans with tomorrow's spot prices, which the power market has set per quarter-hour since October 2025 (many electricity contracts still show an hourly price), and moves flexible load such as hot water, heating and ventilation to the cheapest periods. If the site has a battery, it charges when power is cheap. The plan accounts for the capacity charge at the same time, so a cheap hour does not become a new peak. With more wind and solar power, prices swing more, and being able to move load becomes worth more.
What does the system consist of?
spotEQ PeakGuard is the solution: a control unit in your electrical cabinet, planning in the cloud and the PeakGuard app, where you follow operation, the plan, alarms and calculated savings. A battery in 50 kWh modules is added when the site needs it. Everything comes from one supplier.
Cost and payback
What does a commercial battery system cost?
The price depends on how large a battery the site needs, that is its power in kW and capacity in kWh. We calculate that from your meter data in the free site analysis. The proposal shows the one-off cost of battery and installation and the monthly fee for the PeakGuard app, next to the calculated annual saving.
How long is the payback period?
It depends on the load profile and the local tariff, so we calculate it for each site. The proposal shows the cost next to the calculated annual saving, split into capacity charge, energy price and connection and calculated from your own meter data and last year's prices. We do not promise a return, and you see the figures before you decide.
What are the running costs?
The PeakGuard app is a subscription with a monthly fee stated in the proposal, together with the support scope. The battery and installation are a one-off cost.
What are the terms for pilot sites?
The first installations are pilot sites, on terms agreed for each site. You work directly with the engineers developing the system, and operation starts with a test period before automatic control is enabled.
The site analysis
What is a site analysis, and what does it cost?
We go through twelve months of meter values from your site, show where the peaks come from and calculate what keeping the peaks down would have saved, by shifting load and, where needed, with a battery. You also get advice on load you can shift yourself, such as staggered start-up, timers and pre-heating. The analysis is free and takes about a week after we receive the data. A proposal follows within one to two weeks, and nothing is ordered before you approve it.
What data do you need?
Hourly or 15-minute meter values for the last twelve months, the meter point ID and the latest grid tariff invoice. You get the data yourself and send it to us. How to get your meter data from Elhub or your grid company.
Operation and safety
Where does the battery go, and how much space does it need?
The cabinet stands on the floor, indoors, usually by the electrical room, or outdoors along the wall. Dimensions, weight and cooling for the proposed configuration are in the proposal. PeakGuard mounts on a DIN rail in the electrical cabinet.
What happens if the internet connection drops?
PeakGuard carries on with the plan stored on the unit. If the site has a battery, it covers the building's own consumption once the plan runs out, until the connection returns. The limits set at installation apply throughout, and stored measurements are sent when the connection is back.
Can PeakGuard be reached from the internet?
No. PeakGuard connects to the cloud with outbound connections and accepts no incoming connections. Each unit has its own certificate, and software updates are signed and verified before they are installed. There is no remote shell. You can only sign in to the unit itself from the site's local network, with the password printed on its label.
Does the battery provide backup power during a power cut?
The system is designed to lower costs, not to be a backup supply. Whether it can also carry selected loads during an outage depends on how the inverter is configured, and is agreed in the proposal if you need it.
Is the system safe?
Yes. The battery cells are lithium iron phosphate (LFP), chosen for thermal stability and long life, and the pack has its own battery management system that monitors every module. Every command is checked against the limits set at installation, so neither the software nor its users can push the site past them. The system does not replace fuses, circuit breakers or other electrical protection in the building.
What maintenance is needed?
Day to day, the system is monitored in the PeakGuard app, and alarms go to the people you choose. Any inspection interval for the selected battery cabinet is stated in the proposal.
Can we have solar panels or EV chargers?
Yes. Existing solar production is included in the site picture. PeakGuard controls EV chargers today, and hot water, heating and ventilation through the building's control system (SD-anlegget). Other equipment is assessed before it is included in a proposal.
Does it work with a battery we already own?
Possibly. PeakGuard controls the battery we supply. If you have other battery equipment, we check whether it fits before making a proposal.
How does a project run from start to operation?
A project runs in four steps. First a free site analysis, ready about a week after we receive the meter data. Then a proposal one to two weeks later, with the price and the calculated saving. Next, installation and a test period: the system calculates plans and shows what it would have done without controlling anything, and we compare the figures with your invoice. Finally automatic operation, switched on only after you approve. Nothing is ordered before you approve the proposal. How a project runs.
