The city air conditioning built

Houston is the great monument to mechanical cooling. Before air conditioning it was a swampy, subtropical port where summer was something to be endured with shutters and porches, and the population reflected that. Afterwards it became one of the fastest-growing cities in the country, with a downtown of sealed glass towers, a six-mile network of climate-controlled pedestrian tunnels running beneath them, and the first fully enclosed air-conditioned stadium on earth. Every one of those things is, at bottom, an electrical load. This city runs on electricity in a way that is easy to overlook until the day it does not.

That day was 15 February 2021. Winter Storm Uri froze gas wellheads, instrument lines and wind turbines, took generation offline faster than demand could be shed, and brought the Texas grid within minutes of an uncontrolled collapse that would have taken weeks to recover from. Millions of people lost power for days in freezing temperatures, water systems failed, and the state discovered exactly how thin its margin was. Before that, most Houston engineers had spent their careers worrying about hurricanes. Now they worry about both directions.

Texas is also unique in North American electricity terms. ERCOT operates an interconnection that is largely independent of the eastern and western grids, with an energy-only market and no capacity payments, which produces some of the cheapest industrial power in the country and some of the most volatile pricing anywhere. For an industrial operator, decisions about interconnection, load curtailment, on-site generation and demand response are commercial decisions with an eight-figure spread, not just engineering ones. An electrical engineer working in Houston who does not understand the market is only doing half the job.

Facility electrical engineering

Tundra’s electrical group covers the full facility scope: load lists and single line diagrams, service entrance and distribution design, motor control centres, variable frequency drives, transformer and switchgear specification, short circuit and protective device coordination studies, arc flash analysis and labelling, grounding and lightning protection, hazardous area classification under the National Electrical Code, heat tracing, lighting, cathodic protection and the construction packages that let a contractor build it without inventing details.

Arc flash and coordination studies deserve emphasis because they are the ones most often out of date. A plant that has added load, changed a transformer, altered a utility source or replaced protective relays since the last study is carrying labels that are simply wrong, and the people who rely on them are the ones opening the cabinets. Refreshing a study is inexpensive relative to almost anything else on a capital list.

Hazardous area classification is the other perennial. Gulf Coast facilities are modified continuously, and classification drawings drift out of agreement with the plant faster than any other document. Getting them right, and then verifying that installed equipment actually matches, is unglamorous work that prevents the category of incident that ends companies.

Power supply and resilience

Reliability planning here is dominated by two threats. Hurricanes take down distribution networks for days or weeks — Ike in 2008 left much of the region dark for a fortnight, and the derecho and Beryl outages more recently made the same point — and the freeze scenario takes down generation and gas supply simultaneously. Both argue for the same engineering: standby generation sized against a realistic critical load rather than the whole plant, fuel supply that does not depend on the thing that failed, transfer schemes that have been tested, and instrumentation that survives a cold soak.

We also do the economics. On-site cogeneration, gas-fired generation, solar with battery storage and participation in demand response all change the picture, and in an energy-only market the value of being able to curtail during a price spike can dwarf the value of the electricity itself. Those calculations belong in the front-end engineering, not in an operations review two years later.

Automation and control systems

The control side has become the centre of gravity in facility engineering. Tundra designs, reviews and troubleshoots PLC and RTU systems, SCADA architecture and human-machine interfaces, safety instrumented systems and SIL assessment, alarm rationalisation, measurement and flow computer configuration, communications design, and the operational technology cybersecurity that is no longer optional now that field devices sit on networks.

Houston has a particular relationship with remote monitoring, and it comes from an unexpected direction. Johnson Space Center, south of the city off the Gulf Freeway, has been running crewed missions from a room full of telemetry since the 1960s, and the restored Apollo-era Mission Control is a national historic landmark. Several generations of Houston engineers grew up understanding that a wall of live data, watched by trained people with clear procedures, is how you keep a complicated system alive. Applying the same idea to a hundred wellsites is not a conceptual leap here.

Alarm rationalisation is where we push hardest. A control room acknowledging dozens of alarms an hour is a control room where the important one will be missed, and nearly every legacy facility we assess has accumulated exactly that. Reducing an alarm list is engineering work with a direct safety return and a fraction of the cost of equipment upgrades. Cybersecurity is the fast-growing companion problem: segmentation, remote access control, patching regimes and a recovery plan that has actually been rehearsed.

Corrosion, humidity and the practical field

The Gulf Coast environment is hard on electrical installations. Salt air, near-constant humidity and heavy rainfall attack enclosures, terminations and conduit systems; condensation forms inside cabinets that were sealed against water ingress but not against a daily temperature cycle; and equipment operating near the top of its temperature rating all summer ages faster than the datasheet suggests. Enclosure selection, breathers, space heaters, drainage and coating specification are not details here. Lightning is the other constant — this region gets a serious convective season, and surge protection on instrumentation and communications pays for itself in a single storm.

The city outside the substation

Houston’s Theater District has more seats in a concentrated downtown area than anywhere in the country outside Manhattan, with resident opera, ballet, symphony and theatre companies, and the Alley Theatre building is worth seeing even if you skip the play. The Museum District nearby holds nineteen institutions, several free. Discovery Green turned a downtown parking lot into a park that people actually use. Out at NRG the rodeo runs for three weeks each spring and gives away a remarkable amount of scholarship money.

What holds it together is that Houston is a genuinely unpretentious place. It is the most diverse large city in the United States, it does not much care where you came from, and it forms opinions about people based on whether their work holds up. For a consulting engineer, that is an unusually comfortable market to operate in.

Why the Houston electrical group

Because the integrators, panel shops, switchgear vendors and instrumentation suppliers are concentrated here, and a panel can be built, factory tested and shipped on a timescale that would be impossible elsewhere. Because our engineers have commissioned systems in August heat and restarted them after a storm. And because in ERCOT, the electrical design and the commercial strategy are the same conversation.

If your power supply is constraining your options, your control system has grown past what anyone fully understands, your operators are drowning in alarms, or your area classification drawings no longer describe the plant, those are the conversations this group has most weeks.

Design for the technician, not the reviewer

Electrical and control systems are maintained by people who were not in the design meeting, often years later, frequently at night and usually under pressure. The most valuable thing we can do is keep the system simple enough to be understood: standardised hardware across a client’s sites, equipment that is stocked locally, documentation that matches the installation, and a control philosophy written in language an operator can follow.

The temptation to over-engineer is strong in a market with this much technology available. Every additional protocol, licence, gateway and screen is another thing that must be patched, renewed and explained. We specify what the site can actually support, and we say so when a proposed architecture will outlive the client’s ability to maintain it.

Houston makes the practical side easy. Panel shops, integrators and instrument suppliers are concentrated here, factory acceptance testing can be witnessed the same week it is scheduled, and a replacement part is usually available across town rather than across an ocean. That depth is a genuine reliability advantage, and designing to use it is a deliberate choice rather than an accident.

If your control system has grown past the point where any one person understands it, the fix usually begins with documentation and rationalisation rather than with hardware.
