Maxsolar Supplies Solar Power to SAP – Battery Storage Gains Importance in the German PPA Market
Traunstein (Germany) – Energy infrastructure developer Maxsolar is supplying solar power to software group SAP over a period of ten years. The electricity comes from two solar parks in Saxony and Schleswig-Holstein with a combined capacity of 36.5 MWp, both of which are now in operation.
Ten Years of Solar Power for SAP from Two German Solar Parks
Maxsolar and SAP have signed a corporate PPA covering the 25 MWp Memmendorf solar park in Saxony and the Pahlen solar park in Schleswig-Holstein, which has a capacity of around 11.5 MWp. According to Maxsolar, Memmendorf has been feeding in power since April 2026, while Pahlen was commissioned in August. Both plants are now delivering electricity under the contract.
Physical power delivery follows the pay-as-nominated model, under which delivery volumes are fixed in advance and supplied according to an agreed schedule. SAP also receives guarantees of origin for the delivered electricity, documenting its renewable origin.
Maxsolar does not disclose annual delivery volumes, the power price or the financial value of the contract. There is also no information on an allocation to particular SAP sites or data centres.
SAP Also Relies on Long-Term PPAs for Power Procurement
Long-term power purchase agreements are part of SAP’s renewable energy strategy. In addition to PPAs, the company cites guarantees of origin, its own solar power generation and green power tariffs in its 2025 annual report. SAP intends to make greater use of long-term power purchase agreements to raise the share of renewables in its electricity supply and achieve greater price stability. According to its own figures, SAP purchased a total of 230.4 GWh of electricity in 2025 for offices, its own data centres and electric mobility. Of this, 108.9 GWh was used for offices, 97.1 GWh for its own data centres and 24.4 GWh for electric mobility.
Maxsolar plans to expand its business into integrated energy infrastructure for data centres and other energy-intensive sites. This includes generation, battery storage, grid connection and structured power procurement. The company puts its project pipeline at 6.1 GW.
German Market: 3.57 GW of New Contracted Capacity in Nine Months
The German market for long-term power purchase and flexibility contracts has gained considerably in volume in 2026. According to data from market research firm Pexapark, a total of 3,572 MW of newly contracted capacity was registered from January to September. Of this, 1,769 MW was accounted for by conventional PPAs, 308 MW by hybrid PPAs and 1,495 MW by battery storage flexibility contracts.
Quarterly figures rose from 723 MW to 1,364 MW and then to 1,485 MW. However, the volume of conventional PPAs fell in the third quarter compared with the second, from 793 MW to 383 MW. Flexibility contracts, by contrast, reached their highest level of the quarters examined at 794 MW.
In the third quarter, three hybrid PPAs with a combined 308 MW of solar and storage capacity were signed, including 204 MW of photovoltaics. Pure solar PPAs reached only 45 MW.
Maxsolar also signed further hybrid PPAs in 2026. In August, the company agreed a power purchase agreement with DB Energie for a 37 MW solar park and a battery storage system with 15 MW of power capacity and 30 MWh of storage capacity. In October, it followed with another hybrid PPA with Energy2market for a solar-plus-storage project in Waren.
The development underlines the growing importance of flexible marketing models for the solar industry. Low solar market values and frequent negative power prices on the exchange make it harder to market pure solar generation profiles economically. Combining solar with battery storage, by contrast, allows power delivery to be aligned more closely with demand and market prices.
