Mercury Rising – Part 1

Bradley Bathgate, PE
President and Practicing Principal at PWI Engineering

With all of the talk of Combined Heat and Power, CHP, Cogeneration, Cogen, and Distributed Generation there are a lot of medical facilities and academic institutions that want to reduce the costs of producing energy, reduce their carbon footprint, and make a resilient infrastructure. Feasibility studies are the start of this process, and in our company’s opinion one of the most important parts. Don’t ever fall for the free feasibility study. This study will be the road map to the future. I always make the analogy that if you are having a medical problem, you go to the doctor that is going to give you the best advice that is proven with experience, not the one on the corner giving out the free advice. Find the firm that has the most experience and will give you a study that you will feel comfortable sitting in front of your boss and asking for millions of dollars, and possibly putting your job on the line.
