Areas of Expertise

“EPS is the benchmark on which I will measure engineering firms in the future.”
- Kurt Brickley, Port of San Diego

When other engineers say, “It can’t be done,” EPS shows you how it can. For less than you expected. In less time than you could have imagined. By thinking creatively and financially, not by cutting corners. We actively pursue the optimum solution for each engineering challenge you face – and offer solutions based solely on their proven potential for success.


All the expertise you need is right here.


Some engineering firms bring in outside “experts” who spend months creating reports and action steps – only to leave you to your own devices. But EPS professionals offer a wide array of industry expertise. And we’re with you from start to finish. Mitigating risks. Providing actionable data. Custom-designing solutions and implementing them.

EPS serves the technology and energy industries

The breadth of energy technologies analyzed and designed ranges from $12 billion oil refining complexes; to 1900 MW capacity electrical generating facilities; to multi-fuel 100,000 pph steam systems; to redesigning and constructing established chemical and materials processes.

Technology development by EPS includes alternate energies; biofuels and biochemicals; advanced materials; metallurgy; vehicle mechanics; and human reaction and biomedical systems. Our results speak for themselves.

“Project management, estimating skills, engineering, and design are all real core strengths of EPS.”
- Steve Saunders, Plant Manager, PolyOne

Expert Witness Services

johnEPS Founder and General Manager Dr. John Williams, P.E., is a sought-after engineering professional and a featured author and speaker. As an expert witness, his in-depth analysis and substantiating documentation help legal teams take complex issues to the courtroom to make their cases – based on scientific evidence that he translates into easily understandable testimony.

With more than 35 years’ experience in technology development and plant startup/operations, a Ph.D. in chemical and fuels engineering, and an M.B.A. in Finance from the University of Chicago, Dr. Williams offers a unique synergy of solid engineering knowledge and business acumen that extends from technology development to commercialization, and from the plant floor to the boardroom to the courtroom.

“The material can be dry—especially technical material—but John does a really good job at presenting the material in a way that made it interesting. There was a lot of theory but where his presentation was successful were the practical examples that he incorporated.”
- John Havens, Texas Utilities

$2.9 million investment brings $8 million asset value increase

EPS engineers astutely conceived and developed a facility plan including alternate structural building designs for an industrial facility located on a fault line in a seismically active area and liquefaction zone in San Diego Harbor. Their straightforward construction path complied with rigorous building codes, effectively navigating the California regulatory environment and involving several agencies.

The permitting and construction was reduced to 40 percent of the standard construction timeline and the commissioned project completed at 28 percent of the new construction cost.

Environmental compliance was fully achieved – without adversely impacting the construction schedule – including asbestos, lead, and hexavalent chrome remediation, material recycling, and hazardous waste disposal.

“Great visualizers—able to take drawings to reality.”
– Kurt Brickley, the Port of San Diego


Fast-track bioenergy technology scaleup and demonstration

In nine months, EPS successfully designed and constructed a first-of-a-kind , demonstration-scale bioenergy technology for less than $850,000. The project involved scaling up the ammonia fiber expansion (AFEX) process conceived and researched by Dr. Bruce Dale of Michigan State University, which needed developed and demonstration of the technology and its commercialization potential.

Using EPS custom-designed equipment, the scaleup reached 16,000 percent (160x) of the lab quantity. Effectively working with state and local regulatory and safety professionals, EPS successfullydelivered the system on schedule and under budget.

Previously, EPS successfully designed and constructed the continuous ammonia fiber expansion (CAFEX) process for MBI International, which led to conceptualization of the AFEX3 technology.

The AFEX3 demonstration and Dr. Dale were featured in Ethanol Producers Magazine (July 13, 2013).


Facility renovation helps struggling manufacturer net $9.8 million

When an established biotechnology food-grade manufacturing facility faced operating and financial challenges, Dr. John Williams of EPS was called in “to right the ship” immediately. His lean manufacturing analysis – encompassing the technology, manufacturing process, equipment, and organization – led to renovating the existing manufacturing facility and reorganizing the workforce. As a result, net earnings rose from unprofitability to $9.8 million per quarter, while product quality improved and operating costs decreased. Williams’ efforts returned the facility to a high level of profitability within four months.

“John Williams is an expert in the field. He not only renovated the business, but he changed the flow of the product for the company in terms of minimizing distances from raw materials to production to warehousing to shipping. Nobody within the company was thinking that way.”
– Ron Halik, Environmental Engineering Department Manager


Energy complex costs reduced by more than $1.2 million annually

EPS conducted a technical and economic analysis of an energy complex, and developed a strategy for asset management, fuel sourcing, and operating cost savings. Within three weeks, EPS had completed:

  • The physical inspection of steam and electrical generating and cogeneration equipment.
  • Data mining of energy market data, comparing different scenarios including producing energy, buying it, and other alternatives.
  • Assessment of maintenance, capital investment alternatives, and comprehensive operating costs.
  • A strategy to address environmental regulation and compliance.

The new energy and planning strategies EPS developed reduced operating costs by more than $1.2 million per year for the site – while reducing energy use by 68 percent.

“EPS can help with project research and analysis, providing clients with options and how they stack up against one another – equipment-wise and energy use-wise – and help conclude which option is best.”
- Pat Simms, Chief Operating Officer, Green Biologics


EPS was founded by Dr. John Williams, P.E., who has built his career and his business not only by providing innovative and highly profitable engineering solutions but also by ensuring that those solutions are driven by each client’s unique business objectives, timelines, budgets, and desired outcomes.

In fact, EPS has the reputation of providing insightful engineering assessments and creative solutions for projects others deem “unsolvable,” often reaping economic advantages that had previously gone unrealized.

Under Dr. Williams’ leadership, the EPS team consistently meets and exceeds clients’ technical and financial performance criteria, providing rapid and extraordinary return on investment and delivering on-time results under even the most demanding schedules.
