Electric Power Availability: Cold Weather Preparedness

PUBLIC LAW 109–58—AUG. 8, 2005 | ENERGY POLICY ACT OF 2005

Reliability v. Availability

January 25th Joint Meeting of the Nuclear Regulatory Commission and FERC: Docket No. AD06-6-000.  Given the close coupling of electric and natural gas supply with respect to power reliability, the mind boggles at the hostility of the Biden Administration to natural gas anywhere on earth.  Natural gas is critical to generation plant black start capabilities and hospitals, among others.

A selection of the presentations:

Heat Tracing Installation

“Vue de toits (effet de neige)” 1878 Gustave Caillebotte

One of the core documents for heat tracing is entering a new 5-year revision cycle; a consensus standard that is especially relevant this time of year because of the personal danger and property damage that is possible in the winter months.  Education communities depend upon heat tracing for several reasons; just a few of them listed below:

  • Ice damming in roof gutters that can cause failure of roof and gutter structural support
  • Piping systems for sprinkler systems and emergency power generation equipment
  • Sidewalk, ramp and stairway protection

IEEE 515 Standard for the Testing, Design, Installation, and Maintenance of Electrical Resistance Trace Heating for Industrial Applications is one of several consensus documents for trace heating technology.   Its inspiration originates in the petrochemical industry but its principles apply to all education facilities exposed to cold temperature and snow.   From its prospectus:

This standard provides requirements for the testing, design,installation, and maintenance of electrical resistance trace heating in general industries as applied to pipelines, vessels, pre-traced and thermally insulated instrument tubing and piping, and mechanical equipment. The electrical resistance trace heating is in the form of series trace heaters, parallel trace heaters, and surface heating devices. The requirements also include test criteria to determine the suitability of these heating devices utilized in unclassified (ordinary) locations.

Its principles can, and should be applied with respect to other related documents:

National Electrical Code Article 427

NECA 202 Standard for Installing and Maintaining Industrial Heat Tracing Systems

IEC 62395 Electrical resistance trace heating systems for industrial and commercial applications

 ASHRAE 90.1 Energy Standard for Buildings Except Low-Rise Residential Buildings

We are happy to explain the use of this document in design guidelines and/or construction specifications during any of our daily colloquia.   We generally find more authoritative voices in collaborations with the IEEE Education & Healthcare Facilities Committee which meets 4 times per month in Europe and in the Americas.  We maintain this title on the standing agenda of our Snow & Ice colloquia.  See our CALENDER for the next online meeting.

Curlin’

Sport and WellbeingStandards Scotland

The term “curling” is thought to derive from the way the stone moves and “curls” as it travels over the ice. The key feature of curling that sets it apart from other ice sports is the deliberate rotation, or “curl,” applied to the stones as players release them. This rotation causes the stone to curve or “curl” on its path down the ice, adding an element of strategy to the game.

The precise origin of the term is not definitively known, but it likely emerged organically as people described the action of the stones on the ice. The word “curling” has been associated with the sport for centuries, and as the game evolved and gained popularity, the term became firmly established.

The concept of curling is integral to the sport’s strategy, as players use the curl to navigate the stones around guards and other stones strategically placed on the ice. The unique way in which the stones move and interact with the playing surface is one of the defining characteristics of curling, and the name captures this distinctive feature

Scientific American: Why Do Curling Stones Curl?

A curling facility typically consists of several key components to support the sport and provide a suitable environment for players and spectators:

  • Flooding equipment, refrigeration for 3 degrees C, fine mist sprayers, ice planer, infrared thermometers.
  • The playing surface is called a “sheet,” and it is a rectangular area of ice where the game is played. Each sheet is divided into several sections called “curling houses,” which are the target circles.
  • Curling stones are made of granite and weigh around 38 to 44 pounds. Each team has eight stones, and players take turns sliding them down the ice towards the target area, known as the House.
  • The house is the target area with concentric circles marked on the ice. The center of the house is the “button,” and the circles are used for scoring points.
  • The hacks are footholds on either end of the sheet where players push off to slide the stones. The player in control of the stone uses the hack as a starting point for their delivery.
  • Brooms, also known as brushes, are used by players to sweep the ice in front of the sliding stone. Sweeping can affect the stone’s trajectory and speed.
  • A scoreboard is essential for keeping track of the score in a curling game. It typically displays the current score, the end in progress, and other relevant information.
  • Players use locker rooms for changing into their curling attire and storing their personal belongings.
  • A designated area where players can warm up before a game. It may include stretching space and possibly a small practice sheet.
  • A facility usually has a clubhouse or main building that includes amenities such as viewing areas, meeting rooms, a bar, and possibly a restaurant.  In the case of the Windsor Curling Club: Scotch Whiskey
  • Equipment like ice resurfacers or Zambonis are used to maintain the quality of the ice surface between games.

The origin of curling is sketchy but this much is agreed upon:  Curling is thought to have originated in Scotland, and its roots can be traced back to medieval times. The first written record of curling dates back to 1541 in the records of the Scottish city of Paisley, where a challenge was issued for a contest on the ice between two rival churches.

The early form of the game involved players sliding stones across frozen ponds and lochs, attempting to reach a target. Over time, the sport evolved, and rules were established. Early versions of curling stones were likely rudimentary compared to the polished granite stones used today.

Curling gradually gained popularity in Scotland and spread to other parts of the world, especially among Scottish immigrants. The sport found a home in Canada in the 18th century, where it has become particularly popular. The first curling club in North America, the Montreal Curling Club, was established in 1807.  The Detroit Curling Club was established in 1840; one of the oldest curling clubs in the United States, owing much to its across the river relationship with Windsor Canada.

“Port Meadow is absolutely beautiful and a wonderful place to swim. We often swim in a different spot from other open water swimming groups in order to create a more relaxed environment – especially for our beginners. We do special beginners swims on Saturdays, to ease new members into the practise slowly and very carefully.

Safety is paramount, so I’ll walk them in to the water and they can immerse themselves as much as they want. We never allow anyone to jump or dive into cold water – the shock can cause a swimmer to gulp for air and subsequently ingest water; it’s always a gentle process.” — Ellie
