Proterra Energy installed & have serviced my micro hydro for the last 6 years. Their work ethic, knowledge & professionalism have far exceeded anything I had expected. ​ Nothing but great things to say about this company, Highly recommend them!

Coast CroftWest Owner

Proterra was involved in our project right from the start. It was a challenging and ambitious project with energy generation, storage and distribution. To have an adaptable and solutions oriented company like Proterra involved was superb. They are professional and trustworthy and I would recommend them to anyone with an off grid energy project

Off Grid Estate Owner

I’d be delighted to recommend Proterra to anyone thinking of installing a small scale hydro. Our challenge was to build a resilient system in a remote glen to power a small lodge which is let to holiday makers. Terry and Neil designed and installed a system that has exceeded my expectations. They were professional throughout, their expertise shines through their work, they were transparent on costs and came in on time and on budget. I like that they are an owner managed, local business - and they were a pleasure to deal with.
