Electrical Engineer in Calgary, AB | Facility Power & Controls

Power, control and a city that runs on both

In 2001 Calgary did something that got noticed well beyond Alberta: it began running its light rail network on wind. The “Ride the Wind” program tied the C-Train to generation from the wind farms down around Pincher Creek and the Crowsnest corridor, making it the first urban rail system in North America to be powered that way. It was a small thing electrically and a large thing culturally, because it was an oil and gas city voluntarily buying renewable power a decade before that was fashionable. Calgary has always been more pragmatic than its reputation suggests. If the numbers work, it will do it.

Southern Alberta is, in fact, one of the best wind and solar resources in the country, and the province’s deregulated electricity market means industrial power decisions here involve pricing, curtailment and interconnection questions that operators in other provinces simply do not face. An electrical engineer working out of Calgary spends as much time on where the power comes from and what it costs as on the single line diagram itself.

Electrical engineering for facilities

Tundra’s electrical group covers the whole span of facility electrical work: load lists and single line diagrams, service entrance and distribution design, motor control centres, variable frequency drives, transformers and switchgear specification, short circuit and coordination studies, arc flash assessment, grounding and bonding, hazardous area classification, heat trace, lighting and cathodic protection. On a wellsite or a compressor station this is often the discipline that determines whether a project is straightforward or expensive, because the availability and cost of grid power at a remote Alberta location can change the entire concept.

A great deal of our work is remote-site power: comparing utility extension against on-site generation, gas-fired gensets, solar and battery hybrids for low-load instrumentation sites, and the increasingly common arrangement where a pad runs on a generator until a line is built. Each option carries a different reliability profile, a different emissions story and a very different capital number, and the honest comparison is rarely the one the equipment vendor supplies.

Hazardous area classification deserves its own mention because it is where corners get cut. Getting the classification drawings right, and then actually specifying equipment that matches them, is unglamorous work that quietly prevents the class of incident that ends companies. We do it properly, and we redo it when a facility has been modified enough that the original drawings are fiction.

Automation and control systems

The control side is where facilities have changed most in the last twenty years. A wellsite that once needed a daily visit now reports to a screen in a Calgary office tower, and the operator watching it may be responsible for two hundred locations spread from the foothills to the Saskatchewan border. Tundra designs and reviews the systems that make that possible: PLC and RTU programming, SCADA architecture and screens, safety instrumented systems and SIL assessment, alarm rationalisation, measurement and flow computer configuration, communications design for sites with marginal cellular coverage, and the cybersecurity posture that has become unavoidable now that field devices are on networks.

Alarm rationalisation is the one we push hardest. A control room where operators routinely acknowledge dozens of alarms an hour is a control room where the important alarm will be missed, and almost every legacy Alberta facility we look at has accumulated exactly that problem. Reducing an alarm list is engineering work with a genuine safety return, and it costs a fraction of what the equipment upgrades cost.

Remote operation also runs into geography. Coverage in the Deep Basin and along the eastern slopes is patchy, satellite backhaul is expensive, and a communications design that assumed reliable LTE will produce a data set full of holes. We design for the coverage that exists rather than the coverage on the carrier’s map.

A city wired for this work

Calgary’s technical labour market is unusually deep in exactly these skills, largely because the industry here automated early out of necessity. SAIT turns out instrumentation and electrical technologists in volume, the University of Calgary’s Schulich School of Engineering feeds the design side, and the integrators, panel shops and automation vendors are concentrated in the industrial parks along Barlow Trail and out toward the airport. If a project needs a panel built, tested and shipped in three weeks, that is possible here in a way it is not in most cities.

There is also a genuine technology sector now. Platform Calgary’s innovation centre, the accelerators around it and a steady flow of engineers moving between energy and software have blurred a line that used to be firm. Some of the most interesting industrial data work in the country is happening in offices that were, a decade ago, occupied by land departments.

Weather, and what it does to electrical design

Design temperatures here are brutal at both ends. Equipment rated for a Texas summer will behave differently at minus forty, battery capacity collapses in the cold, condensation and freeze-thaw during a chinook get into enclosures that were sealed against rain rather than against a twenty-five degree swing in six hours, and snow loading and ice affect everything from conduit supports to solar array tilt. Building heaters, enclosure heaters and heat trace loads are frequently the largest single electrical load on a small site, and they are routinely underestimated at the concept stage.

Lightning and grounding matter more than the flat prairie suggests. Southern Alberta gets a serious convective season, hail included — this is the most hail-damaged region in Canada — and surge protection on instrumentation and communications equipment earns its cost in a single storm.

Working with a Calgary electrical group

The advantage of engaging an electrical and automation team based here is that they have already met your constraints. They know what the utility will and will not do, what the local integrators can deliver, how long a switchgear order actually takes, and what happens to a commissioning schedule when the site road is closed for breakup. They have also, in most cases, been in the field at minus thirty trying to find out why a device that worked in the shop will not talk on the pad.

Calgary’s working culture helps here too. It is a city where the person designing the system and the person who will maintain it can reasonably expect to be in the same room, and where an engineer who overcomplicates a control philosophy will hear about it from an operator without much diplomacy. That feedback loop makes for simpler, more maintainable designs, which is the only kind that survive contact with a real facility.

If you have a site whose power supply is limiting your options, a control system that has grown past what anyone understands, an alarm flood, or a hazardous area drawing set that no longer matches the plant, those are the conversations this group has most weeks.

Simple systems survive

The most useful thing an electrical and controls engineer can do for an Alberta operator is resist complexity. Every additional device, protocol, licence and screen is something that has to be maintained by a field technician who covers a territory the size of a small country and who will be doing it at minus thirty-two in the dark with a headlamp. We specify equipment that is available locally, we standardise across a client’s sites wherever we can, and we document the system so that the person maintaining it in 2035 has a chance.

That principle applies to control philosophy as much as to hardware. A sequence that requires four interlocks where two would do is not safer; it is a sequence that will be bypassed. A screen with three hundred tags on it is a screen nobody reads. We design for the operator’s attention as a finite resource, because it is.

Calgary’s working culture reinforces this. It is a city where the engineer and the technician often started in the same building, where SAIT graduates and Schulich graduates end up on the same crew, and where anyone who overcomplicates a design will hear about it directly and without much tact. That feedback loop is one of the more valuable things about practising here.

The city also gives its engineers plenty of practice at working around infrastructure that has to keep running. The C-Train moves through downtown at street level with traffic and pedestrians around it, the Plus 15 network threads between buildings owned by two dozen different parties, and the whole downtown core operates through a winter that would close a less stubborn city. Nothing gets rebuilt from scratch here. Everything gets tied into something that is already live, which is exactly the condition most of our brownfield electrical work is performed under.

If you have a project where the electrical scope is starting to look like the critical path, that is usually a sign it deserves attention early rather than late.
