Battery storage.
From idea to grid.
A calculation is the start. A built project is the goal. BESSPLAN connects what is otherwise spread across spreadsheets, emails and separate tools.

How to move your customer’s storage project forward. Compare storage options, explain the decision, prepare the grid connection and coordinate delivery, all with the same project data.

Consumption becomes a decision.
Which storage size suits your customer? BESSPLAN combines the actual load profile with a comparison of concrete storage options.
A short product tour in four chapters. Just keep scrolling.
Customer report
Figures your customer understands.
The calculation stays the same. The customer report turns it into a clear comparison: what does the storage change, and when does it pay for itself?

Grid applications
Enter once. Use it in the application.
Site, contacts and plant data belong to the project. BESSPLAN reuses this information in the grid connection request. You see what is already there and what is still missing.

Project management
One project. One clear next step.
A good business case alone does not connect a storage system to the grid. The project overview shows what is missing next. Tasks show where your team is needed.

Load profile
35,040 values. A full year of power.
Every quarter hour from 1 January 2025 to 31 December 2025. Every further figure is based on this load profile of your customer.

Three storage systems. Side by side.
Selected: 600 kW / 1,200 kWh. €405,000 investment, €145,000 savings per year, paid back after 3.0 years.
Learn moreBefore and after
1,480 becomes 880 kW.
The storage reduces the peak load by 600 kW. Without and with storage come from the same simulation.
Learn moreCash flow
The investment. And its way back.
€405,000 investment, paid back after 3.0 years. That is exactly where the cash flow reaches break-even.
Learn moreCheck fields
Prefilled instead of retyped.
42 of 62 fields come from the project, such as the applicant. Red shows what is still missing, for example the apparent power (kVA).

From project to form.
Recipient and applicant appear in the finished form. In the example it has been submitted to Ilm-Netz GmbH, reference NAB-2026-02731.

The blocker becomes concrete.
The building permit is waiting for site planning. Only once that is done can it move on.

Ask instead
of searching.
One sentence is enough. The project assistant answers from the project and the regulations, reads files and suggests changes that you review before applying them.

Less work.
The platform simplifies the preparation. On request, our engineering team takes over the grid connection, electrical design and tender.

Frequently asked questions
More answersWho is BESSPLAN for?
For electrical and solar contractors, planning offices and project developers who plan battery storage for their customers or their own sites. Sizing, customer documents and project management come together in one workspace.
What does BESSPLAN add to Excel?
Besides the calculation you get a customer report, prepared application documents and a shared project status. Your team works with the same data, tasks and deadlines.
Do I need a load profile for the demo?
No. We show you BESSPLAN with an example project. To size a commercial storage system later, you use your customer’s load profile and electricity bill.
Can I hand off individual tasks?
Yes. You can commission the grid connection, electrical design or tender, for example. You receive the scope and a fixed price before you place the order.
