As temperatures rise globally, extreme heat events are becoming more common, intense, and longer-lasting. While the health and environmental consequences of heat waves are well-publicized, one often overlooked area of vulnerability is the impact on small businesses—particularly when heat events trigger extended power grid failures. The convergence of these hazards poses a significant threat to business continuity, worker safety, and financial stability.
At Fortitude Emergency Management Inc., we work with small business owners to recognize and prepare for evolving threats. Heat emergencies, exacerbated by failing infrastructure and increasing energy demand, represent one of the most urgent and under-prepared hazards today.
A Growing Risk: Heat Emergencies in Numbers
According to the National Oceanic and Atmospheric Administration (NOAA), the United States experienced 23 separate billion-dollar weather and climate disasters in 2023, with heatwaves becoming one of the fastest-growing categories. By 2030, extreme heat is expected to cause $100 billion in annual economic losses in the U.S. alone, per the White House Office of Science and Technology Policy.
Moreover, the U.S. Department of Energy (DOE) reports that peak summer electricity demand has increased by more than 20% over the past two decades, putting unprecedented strain on aging grids. In cities like Phoenix, where the heat index can top 115°F, utilities are often operating near maximum capacity.
When heat waves strike and the grid buckles, small businesses suffer disproportionately—often with no backup plan in place.
Vulnerabilities Specific to Small Businesses
While large corporations often have dedicated emergency management departments and contingency plans, many small businesses lack the resources or awareness to proactively address these risks.
1. Operational Disruption and Downtime
A heat emergency can force businesses to suspend operations, especially if working conditions become unsafe or unbearable. The Occupational Safety and Health Administration (OSHA) recommends halting work when indoor temperatures exceed 95°F and cooling is unavailable—a common occurrence during blackouts.
According to the U.S. Small Business Administration (SBA), 25% of small businesses never reopen after a disaster, including heat-related power outages.
2. Health and Safety Risks to Employees and Customers
High temperatures can cause heat stroke, dehydration, and exhaustion, particularly in retail, warehouse, kitchen, or outdoor environments. In the event of a power outage, air conditioning and fans fail, dramatically increasing indoor heat exposure.
CDC data shows that between 2004–2018, more than 10,000 heat-related deaths occurred in the U.S., and that number is likely under-reported. Small businesses without clear heat illness prevention plans and access to cooling centers or rest areas are exposing staff to serious risk.
3. Inventory and Equipment Loss
Restaurants, medical offices, and grocery stores are particularly vulnerable. During an extended blackout, perishable goods spoil rapidly, resulting in thousands of dollars in losses.
The FDA recommends discarding refrigerated food after just 4 hours without power. Similarly, sensitive electronics and HVAC systems can be damaged by repeated brownouts or overheating, leading to costly repairs.
4. Loss of Revenue and Customer Trust
When a business is forced to close unexpectedly or provide limited services, customers often turn to competitors. Prolonged or repeated closures due to heat and power failures can lead to revenue loss, reputation damage, and long-term customer attrition.
For small businesses operating on narrow margins, this can be the tipping point.
Case in Point: The Texas Power Grid Crisis
In February 2021, a cold-weather blackout in Texas made national headlines. But in August 2023, ERCOT (Electric Reliability Council of Texas) once again came under pressure—this time from triple-digit temperatures. Emergency alerts warned of rolling blackouts, and many businesses had to reduce operations or shut down entirely.
These events highlight the increasing fragility of regional power grids, and how climate-related hazards are no longer limited to traditional seasons or regions.
Building Resilience: What Small Businesses Can Do
Heat emergencies and power outages are predictable and preventable hazards, and preparing for them is no longer optional.
Here are some action steps every small business owner should take:
- Conduct a Heat Hazard Risk Assessment
- Identify how high temperatures could affect your facility, operations, equipment, and workforce.
- Invest in Backup Power Solutions
- Install generators or battery storage systems for critical operations.
- Explore tax incentives or grant programs for energy resilience.
- Develop a Business Continuity Plan
- Include specific protocols for heat emergencies and power loss.
- Designate cooling areas and hydration stations for staff.
- Train Employees
- Create a heat illness prevention program.
- Ensure all team members know emergency shutdown procedures.
- Maintain Communication Channels
- Set up emergency notification systems for employees and customers.
- Use social media and SMS tools to inform stakeholders of closures or changes.
