This project will install Tesla Powerwall 2 batteries in all-electric, storage heated properties in North Devon using an Economy 7 tariff type.

There are about 42,074 households in North Devon and the proportion of fuel poor households is estimated to be 11.6%. According to the Non-gas map, 47.1% of properties in North Devon are off the gas grid. North Devon Homes Ltd is the main social landlord in the area and rents 3,221 homes. Out of these, 623 are off the gas grid and likely to be on Economy 7 electricity tariffs. About 7,000 households in North Devon have Economy 7 meters.

This project installed three different combinations of technologies to 65 all-electric sheltered accommodation flats in Grimsby, Lincolnshire:

Nottingham Community Housing Association (NCHA) wanted to replace the old storage heaters in 24 of their properties. NCHA were involved in an earlier TIF project alongside Greenvision Energy Ltd whereby standard storage heaters and domestic hot water cylinders were replaced with newer versions. The storage heaters were replaced by Dimplex Quantum high heat retention storage heaters and water cyclinders with Dimplex EC Eau Ecsd cylinders.

The project was led by Cheshire East Council.

Learnings from NEA’s Technical innovation fund field trials

The first part of this project is to ensure 11 rural park homes with vulnerable residents are inadequately insulated. The second part of the project is to install battery storage systems in 22 properties with PV.

The project installed and compared the performance of three makes of batteries from, Moixa, Sonnen and Growatt in 41 properties across three London boroughs.

This project installed two different combinations of electric heating systems to 20 x 2-bedroom flats in a tower block in Walsall, West Midlands, also comparing them against a control group who did not receive new heating:
