UK grid software cuts MV solar connection quotes to 15 minutes
VisNet, a UK-based network monitoring company, has launched an automated platform that allows commercial and industrial rooftop solar developers to receive medium-voltage connection assessments in just 15 minutes. This tool enables project owners to determine online whether connection requests are likely to be approved by network service providers, generating cost estimates and connection offers based on customer-submitted data. Supporting new demand connections of up to 2.5 MVA, the platform aims to reduce engineering and development costs for contractors, developers, and installers. Additionally, the system supports low-voltage applications such as residential rooftop solar, home batteries, and electric vehicle chargers, as network operators face increasing volumes of grid connection requests due to electrification.
