For more than 50 years, SOPTIM AG has been a leader in the development of IT solutions and services for all market roles in the energy industry. With more than 400 employees in Aachen and Essen, SOPTIM offers everything from standardized software products to tailor-made project solutions that are necessary for stable and efficient system operation. The cloud-based SOPTIM Elements platform provides energy industry operators in German-speaking countries with tailor-made product solutions that efficiently represent their specialist processes. The partnership between SOPTIM and epilot opens up new opportunities for epilot customers to benefit from the diverse solutions offered by the SOPTIM Elements platform. The cooperation starts with the introduction of SYNC-Mastr, an intelligent solution that enables grid operators to efficiently manage their mandatory tasks in the market master data register (MaStR). Thanks to the fully automated comparison of master data with that of the epilot network connection portal, discrepancies are immediately identified and can be easily corrected. This reduces manual effort and minimizes sources of error, which is particularly important in light of the new registration requirements of the recently adopted solar package for balcony power plants. Further innovative products from the Elements series will be integrated as a result.
