The most profitable energy setup on the market
Battery (BESS) + Load bank + DC charging station in a single setup. The charging station triggers government subsidies for the entire facility, while the battery and load bank provide access to the entire capacity market.
Three components — full market coverage
Battery Energy Storage System (BESS)
Responds in under 30 seconds. Capable of both upward and downward regulation. Access to FCR, FCR-D, FCR-N, aFRR, and mFRR.
Load bank
500 kW resistive down-regulation capacity, which can be connected in parallel to several MW. Supports PICASSO, FCR, FCR-D and FCR-N, integrated directly into Meganet’s VPP platform.
DC charging station
Publicly accessible charging station (OCPP 2.0) — triggers the government subsidy from the Danish Road Directorate's charging station pool for the battery system. Can independently provide downward regulation for FCR-D down and aFRR down.
From potential to turnkey operation
Technical advice & sizing
We map your grid connection, consumption, and investment budget, and size the battery, load bank, and charging station for the combination that provides the best ROI.
Electrical authorization & authority approval
Our own electricians handle all contact with authorities, as well as the requirements from the grid company and Energinet regarding grid connection and pre-qualification.
Grant application
We apply for the Danish Road Directorate's charging station subsidy on your behalf — up to 40% in state grants for the battery system when the pool is open.
Turnkey installation
Our technicians deliver, install, and commission batteries, load banks, and charging stations — from foundations and electrical panels to grid connection.
Market access & ongoing operations
Our VPP platform handles technical qualification and manages the asset continuously across FCR, FCR-D, FCR-N, aFRR, and mFRR.
From 125 kW to 1 MW+
The larger the system, the faster the payback — because project management, containers, and electrical panels account for a smaller share of the total investment. The figures are indicative and scale with the size of the system.
125 kW
Net investment after subsidies: DKK 927,000
Net earnings: DKK 218,958/year
Payback period: ~50.8 months
250 kW
Net investment after subsidies: DKK 1,392,000
Net earnings: DKK 478,750/year
Payback period: ~34.9 months
500 kW
Net investment after subsidies: DKK 2,172,000
Net earnings: DKK 1,002,500/year
Payback period: ~26.0 months
1,000 kW
Net investment after subsidies: DKK 4,047,000
Net earnings: DKK 2,060,000/year
Payback period: ~23.6 months
One plant, the entire reaction hierarchy
The battery's millisecond-fast response covers the fastest services (FFR, FCR-D, FCR, FCR-N), while the load bank's robust capacity ensures solid participation in the slower downward regulation markets (aFRR, mFRR). Together, they provide access to the entire spectrum of system services — instead of only being able to bid into a single market.

A growing market for system services
About Dual Asset
Why does the combination provide a better return than a single facility alone?
Because the three components share grid connection and project costs, while each utilizes different revenue streams — system services from the battery and load bank, and government subsidies triggered by the charging station.
What are the requirements to receive the government grant?
A publicly accessible charging station must be included in the project. See the Grant page for the full requirements and application process.
How long is the contract period with the aggregator?
Typically 1-3 years with the possibility of termination. We will review the terms in detail at the meeting.
How are the battery and load bank sized for our system?
We base our approach on your grid connection, expected operating hours, and investment budget to find the combination that provides the best ROI.
What if the demand for the charging station is low at the beginning?
The role of the charging station in the business case is primarily to trigger the government subsidy — the ongoing charging revenue is an extra bonus on top of the system service revenue from the battery and load bank.
Can the setup be placed anywhere?
It requires a grid connection with sufficient capacity as well as space for the three facility types. We evaluate specific locations as part of the feasibility study.
What are the requirements for the battery energy storage (LER regulations)?
Facilities with Limited Energy Resources (LER), such as batteries, must, among other things, have at least 4 hours of storage in each direction for aFRR capacity bids and an Energinet-approved EMS as part of the prequalification. We account for this when sizing the battery for your facility.
How does the facility ensure that the delivery is approved by Energinet?
Energinet requires a physical and measurable response — a real change in load upon activation. Our VPP platform controls the battery and load bank, ensuring that deliveries always meet the technical requirements of the pre-qualification.
Which system sizes do you offer?
The setup scales from approx. 125 kW to 1 MW+ — the larger the system, the faster the payback, as project management, the container, and the electrical panel account for a smaller share of the total investment. We size the specific configuration based on your grid connection and investment budget.
Who qualifies for the state subsidy?
The subsidy is provided for the battery system — not the charging station itself. Agriculture, commercial properties, and municipalities typically qualify for the Danish Road Directorate's charging station pool.
Are there any costs that have not been included in the figures?
Activation payment, technical qualification, and access to the individual markets are not included in the calculation above — these will be clarified specifically in connection with the pre-qualification for the individual system services.
Who owns the facility?
You can choose full ownership, co-ownership with Meganet, or an operating agreement where we own the facility and you receive a share of the earnings. We will review the models in detail at the meeting.
What warranty comes with the system?
The battery comes with a 10-year standard capacity warranty. The load bank and charging station have their own manufacturer warranties, which we will review in detail at the meeting.
