POC-MAST™

POC-MAST™ - Grid connection solution

Faster. Safer. Greener. More cost-effective.

Why choose POC-MAST™?

POC-MAST™ offers a simpler route to connection while maintaining the highest safety and engineering standards.

Safer and Simpler Installation
POC-MAST™ has been engineered to reduce many of the risks associated with traditional overhead line connections. The structure is assembled at ground level and raised into position using a hydraulic ram system, eliminating the need for major lifting operations and significantly reducing time spent working at height. The use of screw-anchor foundations also removes the requirement for deep excavations, creating a safer and more efficient installation process from start to finish.
Faster Connections with Less Network Disruption
Unlike conventional connection methods, which can require temporary diversions and extended outages, the majority of POC-MAST™ construction activities can be completed before an outage is required. Final connections can often be completed within a single outage window, helping developers accelerate programme delivery and reducing disruption to the wider network. The result is a faster route to energisation and improved utilisation of existing network assets
Reduced Environmental Impact
POC-MAST™ offers a more sustainable approach to overhead line connections. Its compact footprint reduces land take, while screw-anchor foundations can save more than 30 tonnes of concrete compared to traditional solutions. With fewer plant movements, reduced excavation requirements and minimal disturbance to the surrounding environment, POC-MAST™ helps lower the overall environmental and carbon impact of connection projects
Better Value and Proven Performance
By avoiding the need for tower replacement, major modifications and temporary overhead line diversions, POC-MAST™ can deliver significant cost savings compared to traditional connection methods. In some applications, savings of up to 50% have been achieved. Combined with a fully galvanised construction, a minimum 40-year design life and successful operation across multiple UK electricity networks, POC-MAST™ provides a long-term, reliable and cost-effective solution for grid connections.

What voltages can it be used on?

POC-MAST™ has been used on both 33kV and 132kV networks and is designed for overhead line connections up to 132kV.

Can it be used for both generation and demand projects?

Yes. POC-MAST™ can be used for either generation or load applications

Can it support tee-off and loop-in loop-out (LiLo) connections?

Yes. A single POC-MAST™ can provide a tee-off connection, while twin POC-MAST™ structures can be configured as a loop-in loop-out solution.

Which DNO networks is POC-MAST™ approved on

POC-MAST™ has been approved and installed within UK Power Networks (UKPN), Scottish and Southern Electricity Networks (SSEN), Northern Powergrid (NPG), and approval within National Grid Electricity Distribution (NGED).

How do I know if my project is suitable?

Freedom offers an initial high-level suitability review to assess the proposed point of connection and determine whether POC-MAST™ is appropriate for your site and network requirements.

What foundations are used?

The preferred solution uses screw-anchor foundations, reducing excavation requirements, concrete usage and environmental impact while improving installation efficiency.

How long does installation take?

Typical installation programmes range from six to twelve days depending on connection type and tower configuration, with outage requirements significantly shorter than traditional alternatives.

What makes POC-MAST™ different from traditional connections?

POC-MAST™ reduces costs, outages, working at height, excavations, environmental impact and programme duration while helping customers achieve faster grid connections.
