Optisizer supports the efficient planning of renewable energy systems for commercial and industrial customers, based on their energy consumption patterns and electricity costs. The focus lies in the optimal design and economic evaluation of photovoltaic and battery storage systems. Potential savings through self-consumption, peak load reduction and additional revenue opportunities—such as energy trading and arbitrage—are systematically incorporated into the analysis.
The platform also allows for the simple integration of charging stations into renewable systems and the option to connect with dynamic electricity tariffs or spot markets, offering additional optimization potential. Existing or planned photovoltaic installations can be factored in and evaluated alongside storage solutions, resulting in well-founded profitability assessments over the entire project lifecycle—including investment costs, operational expenses, and scenarios related to technology and market development.
Interview with Marcel Kobald, Chief Commercial Officer (CCO) at Optisizer.
What are the main areas of activity of the company?
Marcel Kobald: Optisizer specializes in providing digital tools for the simulation, planning, and optimization of photovoltaic and battery storage systems, mainly for commercial and industrial users. The company’s core product is a web-based platform that enables users to design energy systems using actual consumption data and electricity pricing structures. A key feature is the simulation of battery storage use cases such as peak shaving and self-consumption optimization
In addition to technical design, the platform offers in-depth financial analysis, including lifecycle assessments that factor in capital and operating costs, tariff developments, and profitability projections. The platform also integrates EV charging infrastructure into system planning.
Furthermore, Optisizer offers a partner program that allows consultants, installers, and project developers to use a white-labeled version of the tool, create professional reports, and streamline client communication. These services help reduce planning time, improve win rates, and deliver efficient, data-driven energy solutions.
What are the ranges of products/services?
M.K: Optisizer offers a comprehensive digital platform for the planning and economic assessment of photovoltaic and battery storage systems, particularly for commercial and industrial use cases.
The core offerings include:
- Simulation and dimensioning of PV + battery systems
- Self-consumption optimization
- Peak shaving and optimization
- Dynamic tariff integration
- EV charging station planning
- Partner services, including a white-labeled version of the tool, training, and expert consulting
The tool enables users to model real-world energy usage, simulate different storage and tariff scenarios, and produce reliable financial projections. It also helps partners create tailored, client-facing reports and streamline their sales and planning processes.
What is the state of the market where you are currently active?
M.K: The battery storage market in the DACH region is experiencing sustained growth, driven by rising electricity prices, increasing demand for energy autonomy, and accelerating adoption of solar PV systems. Germany, the region’s largest market, has seen commercial and industrial battery storage installations more than double over the past two years due to supportive regulatory reforms and shifting economics.
Austria and Switzerland are seeing similar trends, with growing investments in grid resilience and sustainability. As businesses face pressure to manage peak loads, adapt to dynamic tariffs, and prepare for EV integration, intelligent storage systems are becoming essential. In this environment, Optisizer’s platform is well-positioned to support accurate sizing, profitability forecasting, and investment confidence.
What can you tell us about market trends?
M.K: Battery storage adoption in the DACH region is rising sharply, fueled by volatile electricity costs, the rapid uptake of solar systems, and corporate sustainability goals. Germany continues to lead in commercial and industrial installations, while Austria and Switzerland are seeing steady expansion.
Falling battery prices—now between €300–400/kWh—are making storage solutions increasingly accessible. Alongside government incentives and regulatory support, this is encouraging more businesses to adopt batteries for self-consumption, peak shaving, and participation in energy services markets.
Another key trend is the growing demand for smart systems that react to dynamic tariffs and grid conditions. This shift favors platforms like Optisizer, which enable detailed technical and financial planning under real-world constraints.
What are the most innovative products/services marketed?
M.K: Optisizer’s most innovative product is its intelligent simulation platform for PV and battery systems. It enables users to model complex scenarios—such as peak shaving, dynamic pricing, and EV integration—using a simple and intuitive interface. The platform supports automated profitability calculations based on real consumption data, tariff structures, and lifecycle cost modeling.
The integration of dynamic electricity tariffs, vehicle charging profiles, and financial forecasting tools makes the platform uniquely powerful. Additionally, Optisizer offers a white-labeled version of the tool for partners, enabling them to deliver professional, branded reports to clients. These features combine technical depth with user accessibility, positioning Optisizer as a leader in digital energy planning.
What estimations do you have for the second half of 2025?
M.K: In the second half of 2025, Optisizer expects continued growth in the commercial PV and battery storage market across the DACH region. Falling battery prices will make storage more attractive to a wider customer base, especially small and medium-sized enterprises. Increasing regulatory support and growing energy costs are expected to drive demand for self-consumption and peak shaving strategies.
Smart control systems will likely become standard, as users seek tools that can respond to tariffs, forecasts, and load profiles. Optisizer is well positioned to support this transition with its simulation-driven approach.
