The World’s Largest Hypermarket Finds a Better Deal With Trinity Power

Getting a better deal is what Walmart shoppers expect – and it’s also what the retailer itself received from Trinity Power in a recent project, converting a former Target store into a new Walmart location. Thanks to Trinity’s expertise, the temporary power required for the project came in significantly under budget, providing savings in both rental fees and fueling.

The project, at the Surrey Central Mall in Surrey, BC, involved the need for temporary power during a complex electrical upgrade at the former Target retail outlet. While other stores at the mall receive their main electrical feed through the mall’s electrical room, Walmart officials wanted this store to have its own individual feed from the local electric utility, BC Hydro. A temporary power solution was desired to bypass the existing equipment while the new construction and conversion project took place.

Trinity Power was initially contacted by Stantec to provide a diesel generator and cable to power the store while the new BC Hydro feed was installed and tested – an effort estimated to take between one and three months. Due to the critical loads involved, the generator, sized at 1000kW @ 600V, would be required to run 24/7, resulting in significant rental, fuel and servicing costs. Thinking a more efficient and affordable option might be available, Trinity proposed a site visit with representatives from Graham Construction and Bridge Electric, the project’s electrical contractor. During the visit, Trinity’s temporary power specialist suggested one of our portable packaged substations, in place of the previously specified generator.

The suggested substation was installed using a 15kV feed from the mall’s electrical room and a low-voltage connection at the newly rechristened Walmart, completely bypassing the existing equipment through the duration of the upgrade. This approach involved more upfront costs for engineering, permitting, installation and ground grid design than the initial generator plan. However, the end result was a considerable savings for the client. Monthly rental charges alone are $16,000 less with the substation, and this option also eliminated up to $73,000 in diesel costs. Overall, assuming a three-month installation, total savings could reach more than $220,000.

By providing a more efficient option at a much lower price, Trinity Power came through with a temporary power solution any Walmart shopper would appreciate.

Using a 1.5 MVA 25KV/12.5KV – 600/347 portable substation instead of a 1000kW generator provided significant savings in both rental fees and fueling… $200,000 over three months.

Trinity Brings Long-Term Solution to Tilbury LNG Expansion

Big projects can require big solutions, and the $400 million expansion of the Tilbury liquefied natural gas (LNG) plant in Delta, B.C., certainly qualifies as a big project. FortisBC broke ground on the project in October 2014 and expects to commence operation by the end of 2016. The site requires electric power – and a lot of it – to keep office trailers, cranes and construction tools running during construction, a need Trinity was able to fill quickly to meet a very tight deadline.

200x400 Substation Banner In their planning phase, construction managers determined that grid supplied, hydro-produced power would be significantly less expensive than electricity produced onsite with generators. But with only a two-month window for design, delivery and installation, they needed equipment and support from Trinity Power to get a 2MVA substation in place.

This was no simple equipment-supply project. During Pre-mobilization and to meet jobsite specific requirements, Trinity Power worked closely with our customer’s electrical engineers to customize the substation. Additionally, Trinity was responsible for helping the customer meet a range of onsite and off-site requirements, including:

  • Factory and Site acceptance tests.
  • Ground-grid design and installation (including an above-ground, framed-in ground grid).
  • Onsite commissioning (including the Grounding Resistance Test and Step & Touch report).
  • Organizing ongoing quarterly maintenance for the duration of the rental period.

This is a long-term rental, anticipated to last at least two years. The alternative for construction managers was to purchase a custom-manufactured substation – but this customer didn’t want the added maintenance responsibilities or storage issues after the project’s completion. Instead, with this temporary-power solution, they gain access to inexpensive and reliable grid-supplied power, with the added peace of mind knowing that all maintenance and logistics will be handled by Trinity Power, a partner they know they can trust.
