A telecom site that fits inside a UK Clean Air Zone
Mitie Telecom needed firm power at an off-grid telecom site sitting inside a UK Clean Air Zone - meaning both emissions and noise had to comply with stricter-than-default urban limits.
The challenge
The site was inside a UK Clean Air Zone - diesel was effectively excluded by the combination of emissions and noise restrictions. A solar-only solution couldn't deliver the firm power profile required, and grid extension was not a viable option.
Mitie needed a generator that could deliver continuous prime power inside CAZ rules, without acoustic enclosures or special permitting.
The solution
Mitie deployed a Bladon MTG12 as the firm-power layer in a hybrid configuration with solar PV and battery storage. The MTG's emissions profile (exceeds eu stage v emissions limits) and its 60 dB LPA at 10 m acoustic profile met the CAZ requirements without additional mitigation.
Switching the MTG to HVO further reduced scope-1 emissions, providing additional headroom against tightening regulation.
The outcome
The site went live and has remained operational without breach of CAZ emissions or noise rules. It demonstrates a practical, off-the-shelf path for telecom operators with sites inside increasingly common urban clean-air zones.
The deployment is also a reference point for similar sites in noise-sensitive locations near homes, schools, and healthcare facilities.
"Putting a generator inside a Clean Air Zone used to be off the table. The MTG is quiet enough and clean enough that it just isn't an issue."
