Energiapartner Leverages Data-Driven Insights to Create Value in the Sales Process

The increasing share of renewable energy necessitates large-scale energy storage solutions. To ensure security of supply and maximum profitability, investments in energy production, storage, and consumption must be planned thoughtfully and based on data. Long-term decisions require thorough calculations – these must be presented in a way that helps all parties make quick and informed decisions.

Clear Profitability Overview for the Client

Energiapartner, an experienced designer and installer of solar parks and battery storage systems, aimed to be a strategic partner for its clients in implementing the energy revolution. To streamline its sales process, Energiapartner joined forces with STACC to create a tool that helps clients quickly and clearly understand the profitability of the proposed energy solution, considering details of equipment, financing, and market participation.

“Investing in a storage solution is a business decision that requires careful consideration. We wanted to provide our clients with information about the profitability of the development project quickly and understandably. Together with STACC, we developed a tool for our sales team that takes into account the specifics of the client’s development project in terms of both equipment and financing details, and allows us to identify the optimal solution for the client,” said Mikk Saar, a member of Energiapartner’s management board.

An Efficient Tool for the Sales Team

The tool created for Energiapartner is based on the logic of an energy system profitability calculator previously developed by STACC, which allows calculating the payback period of an investment based on the client’s energy consumption and the indicators of various energy system components (solar park, electric car charger, and battery). Several components important for Energiapartner were added to the calculation logic: loan financing, revenue from participating in different electricity markets, and the separation of fixed and variable costs.

The tool offers the sales team the ability to:

• Calculations can use up to 60 input parameters, ranging from various parameters of solar power plants and battery systems to fees paid to aggregators. Hourly precision consumption and solar park production data can be loaded into the calculation model.
• Quickly adjust various inputs, including financing terms and market options (e.g., day-ahead or frequency regulation market).
• Save and reuse inputs, making it convenient to create alternative offers for the same client.

For presentation to the client, the tool creates:

• A summary of the calculation results with visualizations that explain the profitability of the investment.
• Detailed tables and formatted reports that can be downloaded and shared with business partners and financiers.

The result is a user-friendly tool that combines complex logic into clear business value for both the seller and the buyer.

Collaboration Process and STACC’s Role

The tool was developed as a complete solution: the client specified their needs and requirements, and STACC handled the development of methodologies, the development itself, as well as application hosting and maintenance. The development took place iteratively, allowing new functionalities to be continuously tested and adjusted based on feedback.

“Based on Energiapartner’s wishes, several new capabilities had to be added to the existing profitability calculator: participation in the mFRR, aFRR, and FCR frequency reserve markets, a detailed PDF report, a loan and subsidy-based financing model, and additional market and network parameters. This allows the sales team to simulate real-life situations as accurately as possible on the one hand, and makes it easy to run through different scenarios on the other. Energiapartner’s industry knowledge significantly complemented the experience of STACC’s development team in the energy sector,” commented Karl Kevin Ruul, a data engineer at STACC.

Reduced Manual Work, Shifted Focus to the Client

The greatest value of the new tool for the sales team was not only the time savings but also the ability to adapt quickly to the client’s needs. Offers that previously required repeated calculations and data entry can now be regenerated in minutes. This shifted the direction of daily work from routine calculations to strategic collaboration.

“Sales work is intense and time-critical. Many offers are in progress simultaneously, there are different solution options, and manually calculating all of them took hours. If the client wanted to change something, we previously had to start the calculations from scratch; now, we can use pre-saved inputs and quickly create a new, updated report for the client to discuss with business partners and the bank. Instead of routine calculations, I can now focus more on designing the best solution for the client,” said Karl Miilits, a sales engineer at Energiapartner.
