Experience To Match Challenging Demands

What we Do

Valdes has established an experienced team for utility plant retrofits and upgrades. Our mix of personnel —including utilities, independent power producers, equipment manufacturers and engineering firms — allows us to approach your project with the highest degree of technical expertise and with the mindset of an owner. Valdes provides attention to detail but is also practical and cost-effective. We bring this same approach and expertise to steam production and distribution, gas storage and gate stations, renewable energy and water treatment plants.
