TIP and Cornerstone strike strategic deal to accelerate UK mobile infrastructure
Telecom Infrastructure Partners( TIP) and Cornerstone Telecommunications Infrastructure Limited have signed a long-term strategic portfolio agreement designed to streamline telecommunications site renewals and support the development of mobile infrastructure across the UK.
The partnership establishes a framework covering sites managed by TIP, creating a consistent approach to activating and renewing telecommunications agreements as existing contracts expire. The companies said the arrangement would improve operational efficiency, provide greater investment certainty and support faster development of digital connectivity.
Under the agreement, TIP and Cornerstone will establish a shared portfolio of sites operating within the framework. A transparent commercial model will also be introduced, supported by an agreed Consumer Price Index( CPI)-linked rate card.
The partners will strengthen site management and technical information sharing while introducing mechanisms intended to resolve operational issues more efficiently.
The agreement is designed to provide greater certainty for landowners, infrastructure providers and mobile network operators while supporting continued investment in resilient UK mobile infrastructure.
Pat Coxen, CEO, Cornerstone, said:“ The future of UK digital infrastructure will be built through long term collaboration, responsible investment and strong partnerships that create value for everyone involved.”
Mark McKenna, Director of Strategic Partnerships, TIP, said the partnership was critical to establishing a long-term framework that delivered greater consistency, efficiency and certainty around telecommunications site renewals.
He added that the agreement would create a more united approach benefiting landowners, infrastructure providers, mobile network operators and the wider telecommunications industry while supporting future investment in the UK’ s digital infrastructure and connectivity.
Stem PowerTrack EMS to hybridise Hungarian solar plants with 160MWh battery storage
Stem has expanded its role in Hungary’ s renewable energy market after Solarmarkt Group selected its PowerTrack Energy Management System to hybridise two operating utility-scale solar plants with battery storage.
Under a five-year agreement, Solarmarkt and engineering, procurement and construction partner Pannonwatt Energetikai Megoldások will deploy PowerTrack EMS across solar facilities in Szihalom and Hódmezővásárhely. Each 60MWp solar plant will receive a 40MW / 80MWh battery energy storage system, adding 160MWh of storage capacity across the two sites.
Stem previously supplied power plant control capabilities for the facilities during 2025 and 2026 using its hybrid-ready PowerTrack architecture. The expanded deployment will integrate solar generation, storage, grid interconnection and market dispatch through one software and controls platform.
PowerTrack EMS will coordinate battery dispatch, solar output, grid constraints and market instructions while supporting compliance with E. ON distribution requirements. The initial commercial strategy will target Hungary’ s automatic Frequency Restoration Reserve market, with future support planned for Frequency Containment Reserve services and cross-border value stacking.
Matt Tappin, President of Software, Stem, said the project showed how existing solar plants could become hybrid assets without replacing their controls foundation.
The projects will also support Solarmarkt’ s Green Cloud Platform, which connects renewable generation with corporate energy consumers. Stem said combining storage with advanced controls could make renewable electricity more flexible, controllable and commercially valuable as Central and Eastern European power markets become increasingly interconnected.
Pannonwatt said the deployment could establish a technical benchmark for European hybridisation. •
