Ann Turnbull (CEO, Lynden Aged Care)

It's the uninterrupted power supply as much as the power usage that we thought was of great benefit to us. I do tours of prospective residents probably every day of the week and one of things I say is that we generate our own electricity and people are just blown away.

– Ann Turnbull (CEO, Lynden Aged Care)

Cameron Forbes (Engineering Manager, Walker Collins Square)

The reliability of the operation of the microturbine was a big factor but being in a quite dense commercial development... noise was a big factor as well. The microturbines are quiet – you don't get any Breakout noise at all, so that has been a really good point.

– Cameron Forbes (Engineering Manager, Walker Collins Square)

Chris White (Operations Manager, Walker Collins Square)

The reason why we chose Optimal, and the Capstone turbines is to put quite simply, they are proven to work… they run at high load, they run at low load, and they just operate! We have also entered into a 5-year Factory Protection Plan as well – so, having the peace of mind to know that everything is covered under a warranty, and we have got fixed costs for 5 years was really integral.
