We don't sell services - We provide solutions







ESG provides solutions to support the operation, maintenance and license renewal or plant life extension of nuclear utilities. We understand our client's needs because we have been there. We have extensive experience, not only working for companies which provide products and services to utilities, but working in utilities themselves. We have worked for, or at, over 20% of US commercial nuclear sites over a period spanning several decades.

What sets us apart?

Unlike many consultants, we know utilities from the inside-out.
ESG understands the needs of utilities because we have worked for utilities serving in a wide variety of capacities. We have decades of direct experience and have served as:

We leverage the diversity of our plant experience to give you a solution that represents Best Practice.
At ESG we not only have extensive experience with a broad and diverse range of positions within NPPs, we have extensive experience with a large portion of the US commercial nuclear fleet. This means we have seen how similar functions are handled in other plant designs so we can apply proven technologies and approaches based on that diversity of experience to give you the solution that works best and/or is most cost effective.

We find the best solution, rather than a solution.
Every component and piece of equipment is part of a system. At ESG we integrate knowledge of equipment, function, and plant operation that we gained working In plants, and a knowledge of electronics, mechanics, material properties, and failure modes that we've gained testing and qualifying equipment for various manufacturers, to understand your system with both the breadth and depth that is necessary to find the best solution.

We'll correct the cause - not just fix the problem. This prevents recurrence when addressed on a programmatic basis.
Some problems manifest themselves as an equipment failure or mal operation, but are in actuality related to causes external to the equipment. At ESG, our breadth of experience and diversity of expertise in materials, mechanics, chemistry, and electronics enable us to look at a component or piece of equipment as part of a system that is affected by its environment and which affects its environment, and not a stand-alone machine. Some examples might be:

We have intimate knowledge with and direct experience applying and reconciling relevant standards.

We can help your plant operate more cost effectively.
Unlike some consultants who want to maximize the money you spend, we understand that the best way to sell our services is to help maximize what you save. We look for ways to increase system and equipment availability and lifetime in order to reduce your cost of maintenance and replacement. We want to reduce your outages and increase your time online and ALARA control. And helping you get an INPO1 rating saves you money on insurance. We can help accomplish this by, for example:
