Key claims

• Aiolos is positioned by Vitec as a leading European load-forecasting system, developed in close contact with leading European energy-market companies.
• As of release 12.1 (verified live 2026-09-23), the product is under active development: a modern, fast, secure and flexible API for data transfer; a 10x performance boost for Follow Up (via an expanded Homelive follow-up structure); and the “birth” of Battery Optimization, letting batteries connect to multiple sources of charging/discharging units. Not verified: a claimed “support for additional weather-data suppliers including global-coverage Meteomatics data” — no mention of Meteomatics or new weather-data suppliers was found on the 12.1 release notes, the product page, or the release-notes index as of this re-check; removed pending a source.
• An older (2017) analyst estimate circulating online put Aiolos at roughly 60% of the Nordic electricity-forecasting market and around 90 Swedish customers — not used in this wiki: the figure is nine years stale, from a paywalled/gated analyst post this ingest could not independently verify, and the product itself has changed materially since (API, battery optimization, new weather integrations). No current customer-count or market-share figure was found to replace it.
