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:

“Long Term Reliability Assessment” – Presented by Mark Lauby, Senior Vice President and Chief Engineer, NERC

“Grid Reliability Overview & Updates” – Presented by David Ortiz, Director of the Office of Electric Reliability

“Status of Standards and Implementation for Cold Weather Preparedness and Applicability to Nuclear Plants” – Presented by David Huff, Electrical Engineer, Office of Electric Reliability

“Gas-Electric Coordination Since Winter Storm Uri” – Presented by Heather Polzin, Reliability Enforcement Counsel, Office of Enforcement

“Overview of Power Reactor Activities” – Presented by Andrea Kock, Deputy Office Director for Engineering, NRR

“Grid Reliability Updates” – Presented by Jason Paige, Chief, Long-Term Operations and Modernization Branch, Division of Engineering and External Hazards, NRR

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.  Without electric heat tracing; much of the earth would be uninhabitable.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

Inglenook

The home is the empire! There is no peace more delightful than one's own fireplace. - Marcus Tullius Cicero

"Firelight magnifies the soul of a room, and it is there that life unfolds in its purest form" -- Thomas HardyRobert Frost: "Some say the world will end in fire, some say in ice."

An inglenook is an intimate space typically found beside a fireplace. Inglenooks often have built-in seating or benches, providing a comfortable spot for people to gather around the warmth of the fire.  Originally inspired by cooking, but over time, they became more functional as spaces for relaxation, reflection, reading and socializing.

* Lyndon B. Johnson played a significant role in the passage of the Education Acts of 1965, which consisted of two key pieces of legislation: the Elementary and Secondary Education Act (ESEA) and the Higher Education Act (HEA).

As President of the United States, Johnson made education reform a priority of his administration and saw it as a means of addressing poverty and inequality in America. He signed the ESEA into law in April 1965, which was designed to provide funding to schools serving low-income students and aimed to close the achievement gap between disadvantaged students and their more affluent peers. The ESEA also provided funds for teacher training and other educational programs.

In November of the same year, Johnson signed the HEA into law, which provided funding for college and university education and sought to make higher education more accessible to all Americans.

Together, these Education Acts of 1965 were a significant achievement for Johnson’s administration and played a crucial role in expanding educational opportunities for millions of Americans. They marked a major shift in federal education policy and helped to establish the federal government’s role in shaping education policy in the United States.
