innosolvenergy is a modular IT system from innosolv AG of St. Gallen, Switzerland, developed specifically for energy utilities. It supports the sale, metering and billing of electricity, gas, district heating, water and other services, with an automated meter-to-cash process. It also includes a mobile app for sales staff and meter readings, a link to the utility's own customer portal, an integrated document management system, and functions for energy data and meter data management, including data exchange with market partners.
innosolv AG is headquartered in St. Gallen, Switzerland; the website names no foreign parent company. According to the vendor, data and programs can run in your own premises or in the cloud of an authorised Swiss data centre, as you prefer, so data can stay in Switzerland. Switzerland is not an EU member but is an EFTA country with an EU adequacy decision for personal data. For European utilities, running the system under their own control matters for customer and metering data; ask the vendor about sub-processors and support arrangements.
