Episode #13 - Tumalow, saving you energy like never before

Show notes

Talking about energy efficiency is the least sexy of all sustainable business subjects. And, frankly, its a hard sell.

But then you start talking numbers and suddenly operators of mid-size companies start to pay an interest. That's certainly the case for William Gathright, CEO of Tumalow (right) (I'll let him explain what the name of the company actually means) – a company that is trying to shake up the way it helps companies reduce electricity costs and earn extra revenue for commercial properties through an intelligent battery energy storage system (BESS) software.

With most energy firms billing companies on both their consumption and their load (demand), commercial properties pay hundreds of times more than needed for electricity. In fact, the demand charge can account for 70% of a properties’s electric bill. Gathright and his team want to change all that.

"Commercial solar PV systems alone cannot reliably reduce demand charges, because a property's peak power usage frequently occurs during times the sun isn’t shining," says the company's website. That's where Tumalow’s BESS software comes into play.

You can find out more about Tumalow on the website, or follow the company on Twitter.

This video offers a useful introduction to the business too:


Elsewhere on this week's show, we chat with Jake Backus, the former customer sustainability director at Coca-Cola in Europe – a man who knows a thing or two about how you should talk to Joe Public about sustainability issues. You can find out more about Jake here.
