Expert Perspective

Why does their job matter?
Trimark team members explain.

We start by understanding our client’s needs. One way we do this is by creating a system block diagram to show Trimark’s equipment and scope. Our customers often rely on our diagrams to make sure everyone is on the same page.

Russell Stansbury

Proposal Manager

The systems we design are a small, but critical, part of power generation. We design the ‘brains’ that monitor and control each resource to be reliable and durable – in some very tough environments. I’m proud to do my part to leave a lasting benefit for society.

Vince Brashear

Director of Engineering and Design

I help users put Vantage to work for effective resource management. As a bridge between customers and our software team, I write documentation delivered on every system screen that explains Vantage functions such as controls and reporting. That answers most user’s questions right on the spot.

Rob Towns

Customer Success Program Manager

Last summer when temperatures topped 117 degrees and power demand reached a record 52 GW, California faced a real threat of blackouts. Our team worked nights and weekends to commission SCADA to control two BESS resources that added 227 MW of critical reserves just in time to help avoid a crisis.

Tom Noble

Director of Project Engineering

Over the last 20 years, we’ve helped over 900 resources navigate CAISO’s NRI. With owners building more utility-scale renewable generation nationwide they’re now asking Trimark to help them comply with PPA and interconnection requirements in ERCOT, MISO, ISO New England, NYSERDA – really anywhere that complex agreements require expert advice.
