Utilities

Experience to match challenging demands

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.

Roof Top Solar Energy - PV Design

Roof Top Solar Energy - PV Design

An international manufacturer of automotive components needed a plan for the installation of solar panels on the roof of their plant as a part of their sustainability plan. Prior to installation, various engineering services were required to properly layout the project, while technical support was needed to complete the installation prior to and during construction.

480V Load Centers

480V Load Centers

A power plant had numerous 480V load centers (LCs) that had reached their end of life and most had no spare capacity. It was clear to the client that this was an undertaking that would require many years of dedicated work to evaluate the LCs and develop a plan for their replacement.

Switchyard Upgrade - Electrical Study, Transformer Replacement, and Chiller Installation

Switchyard Upgrade - Electrical Study, Transformer Replacement, and Chiller Installation

A client was looking to sell its trigeneration facility and required mechanical and electrical upgrades. Due to the installation of a new upstream substation, options for electrical distribution upgrades to a facility consisting of a steam plant, a chiller plant, and three generating units were necessary. They needed a report and total installed cost (TIC) estimate to approve the project.

Substation Upgrade Project

Substation Upgrade Project

A refinery client initiated a project to increase the incoming power capability from the local utility to the 34kV busses at its refinery. They needed to upgrade various aspects of its 34kV power distribution system due to the increase in available fault current and power capability provided by the new transformers (max 40MVA rating) and 138kV overhead structures and bus work.

Switchgear Replacement Study and Implementation

Switchgear Replacement Study and Implementation

The units and switchgear for our client’s power plant had been in service for over 60 years, were nearing their end of life and presenting reliability concerns. Our client wanted to install upgrades to the 4kV switchgear and needed to know all of their options to get the project approved and funded.
