Full Service I&C and Electrical Maintenance (I&C-E)

IC Electrical

BHI Energy is a full service integrated maintenance company.  BHI I&C-E performs all aspects of electric power industry corrective, planned and modification maintenance.  As a full service I&C-E Company, BHI performs protection and control circuit calibrations, data acquisition and analysis, system modifications, circuit troubleshooting and equipment repairs.  BHI has successfully supported all the major utilities with Electrical and I&C services for both outage and on-line maintenance. BHI Energy’s leadership team keeps safety as an uncompromising value for every individual and every activity carried out across all Nuclear, Fossil, Renewable and Transmission & Distribution work sites.  Our process and programs ensure that Nuclear, Industrial, Radiological and Environmental Safety are carried out as a collective responsibility of the entire organization.

Industry-Recognized Training Program
We have the unique ability to train and qualify our technicians through a performance-based technical training and qualification program.  The program meets EPRI standards and is modeled after utility-based training requirements.  This enables our technicians to work independently of utility supervision.

Our systematic approach training and qualification program has been accepted as equivalent to several utility training programs.  This reduces time and cost by minimizing on-boarding training and qualification requirements.

BHI Energy maintains a staff of trained and qualified I&C-E technicians meeting ISA standards.  We also have a team of subject matter experts ready to perform maintenance and calibrations on the full range of system control and protection circuits.

Integrated Project Approach
BHI Energy provides an integrated planning and project management program to safely execute our I&C-E projects on schedule and on budget.  Our integrated process includes extensive pre-planning, hands on work package review and a comprehensive series of management reviews, risk assessments and development of contingency plans.

First Time Quality
BHI Energy implements a rigorous “first time quality” process that augments site work instructions and procedures to ensure that component-level risk assessments are conducted and mitigating strategies are developed.
