Welcome to "Inside the Park," where we explore the hidden mechanics that keep the Attractions Industry running efficiently. Today’s focus is on a technology that is often described as the "Invisible Green Machine": Power Factor Correction (PFC). This webinar is sponsored by a joint venture between Cincinnati-based Energy Efficiency Group and the Attractions Group.
While many theme parks and zoos gain public recognition for visible sustainability efforts like solar farms or eliminating plastics, PFC offers a direct hit to the bottom line and a faster return on investment—often within 12 to 24 months.
Here is an overview of why this technology is a game-changer for the attractions industry:
The "Beer Foam" Analogy:
To understand PFC, our friends at the Attractions Group suggest thinking of a glass of beer. The liquid represents Working Power (kW), which does the actual work of running a roller coaster’s lift hill or a wave pool’s pump. The foam at the top is Reactive Power (kVAR); it is necessary to create magnetic fields for motors but doesn't perform actual work. The total contents of the glass represent the Apparent Power (kVA) that the utility company must supply. Power Factor Correction is essentially the process of "minimizing the foam" so you only pay for the "liquid" you actually need.
Why Attractions are Ideal Candidates
Amusement parks, waterparks, and zoos are perfect candidates for PFC because they rely heavily on inductive loads:
Amusement Parks: Utilize hundreds of electric motors for ride systems and hydraulic pumps.Waterparks: Run massive, high-horsepower pumps 24/7 for filtration.Zoos & Aquariums: Depend on constant-run life support systems and industrial-scale HVAC for climate control.
The Financial and Operational Benefits
Implementing PFC provides several immediate advantages to a park's P&L:
Elimination of Penalties: Many utility companies charge "Reactive Power Penalties" for low power factors (usually below 0.90), which can cost major parks tens of thousands of dollars monthly.Increased System Capacity: By "clearing the foam," a park frees up capacity on existing transformers. This allows for the addition of new rides or exhibits without the massive expense of upgrading an electrical substation.Extended Equipment Life: High reactive power causes heat; optimizing electrical flow allows motors and transformers to run cooler and last longer.
Why It Is Often Overlooked
Despite these benefits, PFC is frequently ignored because it is invisible—capacitor banks sit in gray metal boxes in back-of-house areas and provide no "eco-theming" for guests to see. Additionally, complex energy bills and siloed departments often mean that sustainability teams focus on guest-facing waste while facilities teams lack the capital budget for these infrastructure improvements.
Ultimately, for a large-scale resort, correcting a poor power factor is a measurable sustainability win, equivalent to taking dozens of cars off the road by reducing line losses and making equipment more "digestible" for the electrical grid.
