ENERGY consultancy TNEI has expanded into new premises after securing a contract with supermarket chain Tesco.

The company has moved to Milburn House, in Dean Street, Newcastle, as it works with Tesco to roll-out renewable energy technology at retail sites throughout the UK.

TNEI has a team of five planners working on the Tesco programme, which covers 1,500 sites. It is focusing on about 100 stores that offer the best wind turbine installation opportunities.
