Electrical Resource Adequacy

 “When buying and selling are controlled by legislation,

FERC Home  Ω  Reaction: February 19 Open Meeting

US K-12 schools (public school districts) spend approximately $8 billion annually on energy costs, including electricity, which ranks as the second-largest operating expense after teacher salaries. This figure, cited by the U.S. Department of Energy and EPA, reflects nationwide totals, with much of it electricity-related due to lighting, HVAC, and other needs; efficiency improvements could save 10-30%.

For colleges and universities, specific nationwide electricity or total energy cost aggregates are less uniformly reported in recent sources, but higher education institutions face substantial utility bills—often over $100,000 per large building annually—with campuses consuming significant power for 24/7 operations, research labs, and facilities.

US healthcare systems, particularly hospitals, incur high electricity costs due to continuous operation and intensive equipment use. Individual hospitals often pay $600,000 to over $2 million yearly on electricity alone, with average energy costs around $3-4 per square foot; inpatient facilities consume nearly twice the electricity per square foot of average commercial buildings.These sectors represent major institutional energy consumers, where efficiency upgrades yield significant savings.

Comment on FERC Action

The Federal Energy Regulatory Commission is an independent agency within the U.S. federal government that regulates interstate transmission of electricity, natural gas, and oil. It oversees wholesale energy markets, pipeline infrastructure, and hydroelectric projects, ensuring fair rates and reliability. While independent, FERC operates under the Department of Energy’s umbrella but does not take direct orders from the executive branch.

FERC enforces energy laws, approves infrastructure projects, and regulates market competition. FERC plays a crucial role in balancing economic, environmental, and energy security concerns, aiming to maintain a stable and efficient energy system across the United States.  Since the U.S. shares interconnected electricity grids with Canada and Mexico, FERC’s decisions on transmission rules and pricing affect energy flows and grid reliability in both countries.

Our interest lies in closing a technical gap that exists upstream from the building service point and downstream from the utility supply point. Some, not all of it, can be accomplished with titles in the IEEE catalog.

Given the dominance of vertical incumbents in the electric power domain, we have submitted a tranche of reliability concepts into the ASHRAE, NFPA and ICC catalogs — not so much with the expectation that they will be gratefully received — but that our proposals will unleash competitive energies among developers of voluntary consensus standards.

One of our proposals was heard at the April-May and October meetings of the International Code Council.  We are happy to discuss the outcome of that proposal any day at the usual hour.

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

 UPDATED POLICIES ON U.S. DECARBONIZATION AND TECHNOLOGY TRANSITIONS


June 15:FERC Finalizes Plans to Boost Grid Reliability in Extreme Weather Conditions

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

Interconnected Electric Power Production Sources “Microgrids”

“Landscape with a Farm House and Windmill” (1680) / Jacob Isaaksz van Ruisdael

We have always taken a forward-looking approach to the National Electrical Code (NEC) because there is sufficient supply of NEC instructors and inspectors and not enough subject matter experts driving user-interest ideas into it.  Today we approach the parts of the 2023 NEC that cover wiring safety for microgrid systems; a relatively new term of art that appropriates safety and sustainability concepts that have existed in electrotechnology energy systems for decades.

Turn to Part II of Article 705 Interconnected Electric Power Production Sources:

Free Access 2023 National Electrical Code

You will notice that microgrid wiring safety is a relatively small part of the much larger Article 705 Content.   There were relatively minor changes to the 2017 NEC in Section 705.50  — but a great deal of new content regarding Microgrid Interconnection Devices, load side connections, backfeeding practice and disconnecting means — as can be seen in the transcripts of Code-Making Panel 4 action last cycle:

Code‐Making Panel 4 Public Input Report (692 Pages)

Code-Making Panel 4 Public Comment Report (352 Pages)

Keep in mind that the NEC says nothing (or nearly very little, in its purpose stated in Section 90.2) about microgrid economics or the life cycle cost of any other electrical installation.  It is the claim about economic advantages of microgrids that drive education facility asset management and energy conservation units to conceive, finance, install, operate and — most of all — tell the world about them.

In previous posts we have done our level best to reduce the expectations of business and finance leaders of dramatic net energy savings with microgrids — especially on campuses with district energy systems.  Microgrids do, however, provide a power security advantage during major regional contingencies — but that advantage involves a different set of numbers.

Note also that there is no user-interest from the education facility industry — the largest non-residential building construction market in the the United States — on Panel 4.   This is not the fault of the NFPA, as we explain in our ABOUT.

The 2023 NEC was released late last year.

 

The 2026 revision cycle is in full swing with public comment on the First Draft receivable until August 24, 2024.  Let’s start formulating our ideas using the 2023 CMP-4 transcripts.   The link below contains a record of work on the 2023 NEC:

Underground Electrotechnology

Best practice literature to be covered in our 11 AM session today are listed below.  These codes and standards ensure safety, reliability, and compliance for underground electrical and telecommunications installations:

2028 National Electrical Safety Code

  • National Electrical Code (NEC), NFPA 70
    • Relevance: The NEC, published by the National Fire Protection Association, is the primary standard for safe electrical installations in the U.S. Articles 300 (Wiring Methods), 310 (Conductors for General Wiring), and 230 (Services) cover underground wiring, including burial depths, conduit requirements, and direct-burial cables like Type UF and USE-2. For example, NEC 300.5 specifies minimum cover depths (e.g., 24 inches for direct-burial cables, 18 inches for PVC conduit).
    • Key Aspects: Rules for conductor protection, grounding, GFCI requirements, and conduit types (e.g., Schedule 80 PVC). Adopted by most U.S. jurisdictions with local amendments.

ANSI/TIA-568 Series (Commercial Building Telecommunications Cabling Standards)

  • Relevance: Governs low-voltage telecommunications cabling, including underground installations. TIA-568.2-D (Balanced Twisted-Pair) and TIA-568.3-D (Optical Fiber) specify performance requirements for cables like Cat6 and fiber optics, including maximum distances (e.g., 100 meters for twisted-pair).
  • Key Aspects: Ensures signal integrity, proper separation from high-voltage lines, and compliance for plenum or direct-burial-rated cables. Voluntary unless mandated by local codes.

IEEE 835 (Standard Power Cable Ampacity Tables)

  • Relevance: Provides ampacity ratings for underground power cables, critical for sizing conductors to prevent overheating.
  • Key Aspects: Includes data for direct-burial and ducted installations, considering soil thermal resistivity and ambient conditions. Often referenced alongside NEC for high-current applications.

UL 83 (Standard for Thermoplastic-Insulated Wires and Cables)

  • Relevance: Underwriters Laboratories standard for wires like THWN-2, commonly used in underground conduits. Ensures cables meet safety and performance criteria for wet locations.
  • Key Aspects: Specifies insulation durability, temperature ratings, and suitability for direct burial or conduit use. NEC requires UL-listed cables for compliance.

OSHA 1910.305 (Wiring Methods, Components, and Equipment)

  • Relevance: U.S. Occupational Safety and Health Administration standard for workplace electrical safety, including underground installations in industrial settings.
  • Key Aspects: Specifies approved wiring methods (e.g., armored cable, conduit) and enclosure requirements for underground cable trays or boxes. Focuses on worker safety during installation and maintenance.

CSA C22.1 (Canadian Electrical Code)

  • Relevance: Canada’s equivalent to the NEC, governing underground electrical installations. Similar to NEC but tailored to Canadian conditions and regulations.
  • Key Aspects: Defines burial depths, conduit types, and grounding requirements. For example, low-voltage cables (<30V) require 6-inch burial depth, like NEC.

Notes:

  • Regional Variations: Always consult local building authorities, as codes like the NEC or AS/NZS 3000 may have amendments. For example, some U.S. states reduce burial depths for GFCI-protected circuits (NEC 300.5).
  • Low-Voltage vs. High-Voltage: Standards like TIA-568 and ISO/IEC 11801 focus on low-voltage (e.g., <50V) telecommunications, while NEC and IEC 60364 cover both power and telecom.
  • Practical Compliance: Before installation, call 811 (U.S.) or equivalent to locate underground utilities, and obtain permits/inspections as required by local codes.
  • Critical Examination: While these standards are authoritative, they can lag behind technological advancements (e.g., new cable types like GameChanger exceeding TIA-568 limits). Over-reliance on minimum requirements may limit performance for cutting-edge applications.

Communication in the Presence of Noise

Claude E. Shannon

University of Michigan – Bell Telephone Laboratories – Massachusetts Institute of Technology

Abstract. A method is developed for representing any communication system geometrically. Messages and the corresponding signals are points in two “function spaces,” and the modulation process is a mapping of one space into the other. Using this representation, a number of results in communication theory are deduced concerning expansion and compression of bandwidth and the threshold effect. Formulas are found for the maximum rate of transmission of binary digits over a system when the signal is perturbed by various types of noise. Some of the properties of “ideal” systems which transmit at this maxmum rate are discussed. The equivalent number of binary digits per second for certain information sources is calculated.

Lightning Protection Systems

2026 Public Input Report | 2026 Public Comment Report

FEMA National Risk Index: Lightning

“Benjamin Franklin Drawing Electricity from the Sky” 1816 Benjamin West

 

Benjamin Franklin conducted his famous experiment with lightning on June 10, 1752.

He used a kite and a key to demonstrate that lightning was a form of electricity.

This experiment marked an important milestone in understanding the nature of electricity

and laid the foundation for the development of lightning rods and other lightning protection systems.

 

Seasonal extreme weather patterns in the United States, resulting in damages to education facilities and delays in outdoor athletic events — track meets; lacrosse games, swimming pool closures and the like — inspire a revisit of the relevant standards for the systems that contribute to safety from injury and physical damage to buildings: NFPA 780 Standard for the Installation of Lightning Protection Systems

FREE ACCESS

To paraphrase the NFPA 780 prospectus:

  • This document shall cover traditional lightning protection system installation requirements for the following:
       (1) Ordinary structures

       (2) Miscellaneous structures and special occupancies
       (3) Heavy-duty stacks
       (4) Structures containing flammable vapors, flammable gases, or liquids with flammable vapors
       (5) Structures housing explosive materials
       (6) Wind turbines
       (7) Watercraft
       (8) Airfield lighting circuits
       (9) Solar arrays
  • This document shall address lightning protection of the structure but not the equipment or installation requirements for electric generating, transmission, and distribution systems except as given in Chapter 9 and Chapter 12.

(Electric generating facilities whose primary purpose is to generate electric power are excluded from this standard with regard to generation, transmission, and distribution of power.  Most electrical utilities have standards covering the protection of their facilities and equipment. Installations not directly related to those areas and structures housing such installations can be protected against lightning by the provisions of this standard.)

  • This document shall not cover lightning protection system installation requirements for early streamer emission systems or charge dissipation systems.

“Down conductors” must be at least #2 AWG copper (0 AWG aluminum) for Class I materials in structures less than 75-ft in height

“Down conductors: must be at least 00 AWG copper (0000 AWG aluminum) for Class II Materials in structures greater than 75-ft in height.

Related grounding and bonding  requirements appears in Chapters 2 and Chapter 3 of NFPA 70 National Electrical Code.  This standard does not establish evacuation criteria.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

Churches and chapels are more susceptible to lightning damage due to their height and design. Consider:

Height: Taller structures are more likely to be struck by lightning because they are closer to the cloud base where lightning originates.

Location: If a church or chapel is situated in an area with frequent thunderstorms, it will have a higher likelihood of being struck by lightning.

Construction Materials: The materials used in the construction of the building can affect its vulnerability. Metal structures, for instance, can conduct lightning strikes more readily than non-metallic materials.

Proximity to Other Structures: If the church or chapel is located near other taller structures like trees, utility poles, or buildings, it could increase the chances of lightning seeking a path through these objects before reaching the building.

Lightning Protection Systems: Installing lightning rods and other lightning protection systems can help to divert lightning strikes away from the structure, reducing the risk of damage.

Maintenance: Regular maintenance of lightning protection systems is essential to ensure their effectiveness. Neglecting maintenance could result in increased susceptibility to lightning damage.

Historical Significance: Older buildings might lack modern lightning protection systems, making them more vulnerable to lightning strikes.

The risk can be mitigated by proper design, installation of lightning protection systems, and regular maintenance.

Energy Standard for Sites & Buildings: Lighting

University of Michigan

The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) is an ANSI-accredited continuous-maintenance standards developer (a major contributor to what we call a regulatory product development “stream”).   Continuous maintenance means that changes to titles in its catalog can change in as little as 30-45 days.  This is meaningful to jurisdictions that require conformance to the “latest” version of ASHRAE 90.1

Among the leading titles in its catalog is ASHRAE 90.1 Energy Standard for Sites and Buildings Except Low-Rise Residential Buildings.  Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.  Free access to ASHRAE 90.1 version is available at the link below:

READ ONLY Version of 2022 ASHRAE 90.1

If you cannot access it with the link above, try the link below and select 90.1 from the title list:

Current Popular ASHRAE Standards and Guidelines

Chapter 9: Lighting, begins on Page 148, and therein lie the tables that are the most widely used metrics (lighting power densities) by electrical and illumination engineers for specifying luminaires and getting them wired and controlled “per code”.   Many jurisdictions provide access to this Chapter without charge.  Respecting ASHRAE’s copyright, we will not do so here but will use them during today’s Illumination Colloquium, 16:00 UTC.

Keep in mind that recently ASHRAE expanded the scope of 90.1 to include energy usage in the spaces between buildings:

Solar Panels on King’s College Chapel Roof

“…The solar panels will populate the gothic chapel roof, producing an approximate 105,000 kWh of energy a year – enough to run the chapel’s electricity, and saving around £20,000 in energy bills per year. The college confirmed that any excess energy would be sold off to the national grid.

Solar Panels on King’s College Chapel Roof

Solar panels perform better when listening to music:

A 2013 study by researchers at Imperial College London and Queen Mary University of London showed that solar panels actually work better when exposed to music, of multiple genres. Scientists at the university proved that when exposed to high pitched sounds, like those found in rock and pop music, the solar cells’ power output increased by up to 40 percent. Classical music was also found to increase the solar cells’ energy production, but slightly less so than rock and pop, as it generally plays at a lower pitch than pop and rock. Whether they know it or not, British band Coldplay are just one of the artists benefitting from this research. During their 2021 tour, they installed solar photovoltaic panels in the build-up to each show, “behind the stage, around the stadium and where possible in the outer concourses”…

BS 7671 Requirements for Electrical Installations

The Major Differences in Electrical Standards Between the U.S. and Europe

Representative Calculation: (WAG)

To determine how much electrical power and lighting 12 kilowatts (kW) will provide for an educational facility, we need to consider the following factors:

    1. Power Distribution: How the 12 kW will be distributed across different electrical needs such as lighting, computers, HVAC (heating, ventilation, and air conditioning), and other equipment.
    2. Lighting Requirements: The specific lighting requirements per square foot or room, which can vary based on the type of facility (classrooms, libraries, laboratories, etc.).
    3. Efficiency of Lighting: The type of lighting used (e.g., LED, fluorescent, incandescent) as this affects the power consumption and lighting output.

We start with lighting.

    1. Lighting Efficiency:
      • LED lights are highly efficient, typically around 100 lumens per watt.
      • Fluorescent lights are less efficient, around 60-70 lumens per watt.
    2. Lighting Power Calculation:
      • 12 kW (12,000 watts) of LED lighting at 100 lumens per watt would provide: 12,000 watts×100 lumens/watt=1,200,000 lumens
    3. Illumination Requirements:
      • Classroom: Approximately 300-500 lux (lumens per square meter).
      • Library or laboratory: Approximately 500-750 lux.
    4. Area Coverage:
      • If we target 500 lux (which is 500 lumens per square meter), we can calculate the area covered by the lighting: (1,200,000 lumens)/ 500 lux=2,400 square meters

Now we need to allocate power to other loads.

    1. Lighting: Assuming 50% of the 12 kW goes to lighting:
      • Lighting Power: 6 kW (6,000 watts)
      • Using the previous calculation: 6,000 watts×100 lumens/watt=600,000 lumens
      • Area Coverage for lighting (at 500 lux): (600,000 lumens)/500 lux=1,200 square meters
    2. Other Electrical Needs:
      • Computers and equipment: Typically, a computer lab might use around 100 watts per computer.
      • HVAC: This can vary widely, but let’s assume 4 kW is allocated for HVAC and other systems.

Breakdown:

    • Lighting: 6 kW
    • Computers/Equipment: 2 kW (e.g., 20 computers at 100 watts each)
    • HVAC and other systems: 4 kW

Summary

    • Lighting: 12 kW can provide efficient LED lighting for approximately 1,200 square meters at 500 lux.
    • General Use: When distributed, 12 kW can cover lighting, a computer lab with 20 computers, and basic HVAC needs for a small to medium-sized educational facility.

The exact capacity will vary based on specific facility needs and equipment efficiency.

 

 

Stationary Energy Storage Systems

Should every campus building generate its own power? Sustainability workgroups are vulnerable to speculative hype about net-zero buildings and microgrids. We remind sustainability trendsniffers that the central feature of a distributed energy resource–the eyesore known as the university steam plant–delivers most of the economic benefit of a microgrid. [Comments on Second Draft due April 29th] #StandardsMassachusetts

“M. van Marum. Tweede vervolg der proefneemingen gedaan met Teyler’s electrizeer-machine, 1795” | An early energy storage device | Massachusetts Institute of Technology Libraries

We have been following the developmental trajectory of a new NFPA regulatory product — NFPA 855 Standard for the Installation of Stationary Energy Storage Systems — a document with ambitions to formalize the fire safety landscape of the central feature of campus microgrids by setting criteria for minimizing the hazards associated with energy storage systems.

The fire safety of electric vehicles and the companion storage units for solar and wind power systems has been elevated in recent years with incidents with high public visibility.  The education industry needs to contribute ideas and data to what we call the emergent #SmartCampus;an electrotechnical transformation — both as a provider of new knowledge and as a user of the new knowledge.

Transcripts of technical deliberation are linked below:

2026 Public Input Report (705 pages) § 2026 Second Draft Meeting Agenda (912 pages)

Comment on the 2026 revision received by March 27, 2025 will be heard at the NFPA June 2025 Expo through NFPA’s NITMAM process.

University of Michigan | Average daily electrical load across all Ann Arbor campuses is on the order of 100 megawatts

A fair question to ask: “How is NFPA 855 going to establish the standard of care any better than the standard of care discovered and promulgated in the NFPA 70-series and the often-paired documents NFPA 110 and NFPA 111?”  (As you read the transcript of the proceedings you can see the committee tip-toeing around prospective overlaps and conflicts; never a first choice).

Suffice to say, the NFPA Standards Council has due process requirements for new committee projects and, obviously, that criteria has been met.   Market demand presents an opportunity to assemble a new committee with fresh, with new voices funded by a fresh set of stakeholders who, because they are more accustomed to advocacy in open-source and consortia standards development platforms, might have not been involved in the  more rigorous standards development processes of ANSI accredited standards developing organizations — specifically the NFPA, whose members are usually found at the top of organization charts in state and local jurisdictions.  For example we find UBER — the ride sharing company — on the technical committee.  We find another voice from Tesla Motors.  These companies are centered in an industry that does not have the tradition of leading practice discovery and promulgation that the building industry has had for the better part of two hundred years.

Our interest in this standard lies on both sides of the education industry — i.e. the academic research side and the business side.  For all practical purposes, the most credible, multi-dimensional and effective voice for lowering #TotalCostofOwnership for the emergent smart campus is found in the tenure of Standards Michigan and its collaboration with IEEE Education & Healthcare Facilities Committee (E&H).  You may join us sorting through the technical, economic and legal particulars and day at 11 AM Eastern time.   The IEEE E&H Committee meets online every other Tuesday in European and American time zones; the next meeting on March 26th.  All meetings are open to the public.

University of California San Diego Microgrid

You are encouraged to communicate directly with Brian O’Connor, the NFPA Staff Liaison for specific questions.  We have some of the answers but Brian is likely to have all of them.   CLICK HERE for the NFPA Directory.  Additionally, NFPA will be hosting its Annual Conference & Expo, June 17-20 in San Antonio, Texas; usually an auspicious time for meeting NFPA staff working on this, and other projects.

The prospect of installing of energy storage technologies at every campus building — or groups of buildings, or in regions — is clearly transformational if the education facilities industry somehow manages to find a way to drive the cost of operating and maintaining many energy storage technologies lower than the cost of operating and maintaining a single campus distributed energy resource.  The education facility industry will have to train a new cadre of microgrid technology specialists who must be comfortable working at ampere and voltage ranges on both sides of the decimal point that separates power engineers from control engineers.  And, of course, dynamic utility pricing (set by state regulatory agencies) will continue to be the most significant independent control variable.

Finding a way to make all this hang together is the legitimate work of the academic research side of the university.   We find that sustainability workgroups (and elected governing bodies) in the education industry are vulnerable to out-sized claims about microgrids and distributed energy resources; both trendy terms of art for the electrotechnical transformation we call the emergent #SmartCampus.

We remind sustainability trendsniffers that the central feature of a distributed energy resource — the eyesore known as the university steam plant — bears most of the characteristics of a microgrid.   In the videoclip linked below a respected voice from Ohio State University provides enlightenment on this point; even as he contributes to the discovery stream with a study unit.

Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard

Thunderstorm | Shelter (Building: 30/30 Rule)

The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:

  1. Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
  2. Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
  3. Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
  4. Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.

It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.

Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)

There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.

Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.
