Intelligent Land Investments Group plc (ILI Group) is a Scottish clean energy development company specialising in energy storage projects, including Pumped Storage Hydro (PSH) and large-scale battery storage. Originally founded in 2004 as Intelligent Land Investments, the company was incorporated as ILI Group in 2017, consolidating its renewable energy ventures under a single corporate entity. Under the leadership of Mark Wilson, ILI Group has developed a portfolio of over 4.7 GW of energy storage projects aimed at supporting the UK’s transition to net zero.
In 2008, following the global financial crisis, ILI pivoted towards renewable energy, initially specialising in onshore wind development. The company secured planning consents for 96 wind projects out of 160 proposals, establishing itself as a key player in Scotland’s small and medium-scale wind energy sector. [1]

ILI Group has developed and sold multiple battery storage projects, securing grid-scale storage capacity for the UK’s renewable energy system. Key transactions include:
In 2018, the company co-sponsored a discussion paper with Strathclyde University, launched at an all-party meeting in the House of Lords, which called for policy mechanisms to encourage large-scale energy storage investment. [5]
ILI Group is also a key member of the UK Pumped Storage Hydro Working Group, convened by Scottish Renewables, which includes SSE Renewables, Drax Power, and Foresight. This coalition successfully lobbied for a cap-and-floor mechanism for LDES, a policy that was announced by the UK Government in 2025. [6]
