Refineries plan semi and annual turnarounds to upgrade, repair, or maintain specific areas within a plant. When a refinery shuts down a unit, the cost of missed production for refineries and other petrochemical facilities can have a significant impact on operational expenses and production prices. Turnarounds that take longer than anticipated can have serious ramifications for refiners.

United Rentals was asked to provide temporary power, including significant amounts of cable, distribution and switchgear. At times, units required either massive amounts of power or very minimal power. Load Banks were employed to help offset the low power requirements and prevent both the refinery and United Rental's generators from wet stacking and thereby shutting down prematurely due to a low load or voltage drop scenarios. With the United Rentals tunraround solution the refinery was able to finish on time, on budget and with no mechanical issues.
