I've implemented Green Button Connect for Burlington Hydro. Other utilities should be relatively easy to add.
See my post about it here: Utility energy data integration via Green Button Connect.
The first utility I implemented was Burlington Hydro because its my own, but the Green Button implementation for all of the following utilities are all managed by London Hydro. Anybody who is a client of any of these utilities and are interested in trying out the add-in, let me know because it should be a pretty painless process:
- ELK Energy
- Enwin Utilities
- Festival Hydro
- London Hydro
- Newmarket Tay
- Niagara Peninsula Energy
- Oakville Hydro
- Oshawa Power
