Description:
Explains why ski areas have an unusual electric consumption and demand profile compared with most commercial and industrial customers.
What you’ll learn:
- How snowmaking shapes load profile
- Why a power purchase agreement (PPA) isn’t always feasible at a ski area
- Why the ski area load profile can mitigate merchant revenue risk
Why this matters
Most commercial energy projects are underwritten around a fairly predictable load.
A warehouse, office building, manufacturing facility, grocery store, or school may have seasonal variation, but the basic operating pattern is usually understandable. The building opens, equipment runs, HVAC responds to weather, and the load moves within a known range.
A ski area is different.
The biggest electrical events at a ski area are not driven by a calendar. They are driven by weather, and the availability of water, and power. When the wet-bulb temperature drops the mountain has to make snow. That can turn a manageable winter load into a sky-rocketing power event very quickly.
That is why a ski area’s electric load is unique.
The mountain may look like a low-load customer for much of the year, then suddenly behave like a large industrial load during snowmaking windows.
How snowmaking shapes load profile
Snowmaking is not a background load.
It is a large, weather-triggered, operationally necessary load that dominates the electric profile of the ski area. Pumps move water. Compressors move air. Fan guns, hydrants, controls, and related systems come online. The electrical system has to support that load when the mountain needs it, not when the bill makes it convenient.
That matters because demand charges are based on peak power. The utility bill does not care whether the mountain reached that peak because of a perfect snowmaking window, a holiday-week push, or a compressed early-season opening. The peak still shows up on the bill.
The load profile usually has three layers:
- a 2-15% base load from lodges, lifts, lighting, kitchens, buildings, and normal operations
- a winter operating base load when lifts and guest-facing facilities are more active
- a 10x or larger snowmaking load that skyrockets peak demand
Those layers are not equal. The snowmaking layer can define the entire energy strategy.
Why this is hard for conventional energy projects
Many energy developers are optimized to develop behind-the-meter projects that provide contracted revenue in the form of the site host signing an agreement to consume power generated onsite. A ski area has very little (approx. 2-15% of their winter season base load) load consumption, and therefore appetite for offtake.
For solar, the template is often a PPA. The developer builds the system, the customer buys electricity over time, and the savings are based on replacing utility energy charges with a lower contracted price.
That can work well for many customers. It is harder at a ski area.
The reason is not that solar is bad. The reason is that the ski area’s problem is usually not energy consumption alone. The problem is peak power, snowmaking timing, winter demand, and resilience. Solar production may be strongest during periods when the ski area’s load is lower, while the highest snowmaking demand often happens during cold windows, at night, and in winter conditions.
That mismatch does not mean solar has no role. It means solar has to be evaluated as part of a broader system. Solar, as well as other onsite generation, can be an economic multiplier in revenue generation when paired with energy storage.
For a ski area, generation, storage, controls, demand management, and interconnection strategy must be considered together. A standard PPA may reduce energy charges but leave the demand problem mostly unaddressed.
Why the load profile can reduce merchant risk
The same load profile that makes ski areas hard for conventional developers can make them interesting for CutPeak Energy.
A ski area likely uses a large electrical interconnection to support large winter snowmaking peaks, but that interconnection may be lightly used during the shoulder seasons and summer. That creates headroom to monetize the spare grid interconnection.
Headroom is important because a battery or microgrid asset may be able to serve the ski area during winter and serve the grid during other parts of the year. The winter use case is operational. The off-season use case affords the ski season use, and hopefully, profit.
In simple terms:
winter: reduce peak demand, support snowmaking, provide resilience
off-season: participate in utility programs, wholesale markets, or other revenue opportunities where allowed
That does not eliminate merchant risk. Program rules, tariffs, telemetry, interconnection rights, dispatch control, and market prices all matter.
But the ski area load profile can help because the mountain’s highest operational need is often not occurring at the same time as many off-season market opportunities.
How to think about the ski area load
Start by separating the load into operating realities.
Question 1: What is the normal base load?
This is the load that exists when the mountain is not making snow. It may include lodges, lighting, maintenance, refrigeration, communications, pumps, offices, and other steady uses.
Question 2: What is the winter operating base load?
This is the load during ski operations before snowmaking is added. It may include lifts, food service, rental buildings, ticketing, lighting, and other guest-facing operations. Anything you need to ride-through a utility outage for safe enjoyment.
Question 3: What is the snowmaking load?
This is the load that changes the strategy. It is important to understand not only how high the peak gets, but how long it lasts, how often it occurs, and whether it happens during utility or market peak periods.
Question 4: What happens when power is limited?
If the mountain has experienced curtailment, feeder constraints, transformer limits, nuisance trips, generator dependence, or equipment limitations, those details matter. They may affect whether the right solution is storage, onsite generation, controls, utility upgrades, or a plan for the future.
What operators should do first
Before evaluating a PPA, battery, generator, or microgrid, gather the data that shows the load profile.
Take these next steps as a ski area operator to form your energy strategy.
Prepare for introduction call
the most recent electric bill (for each meter)
interval data, if available (login to portal or call utility)
account numbers and meter list (can get from bills)
Prepare for strategic planning call
Nameplate information from all major loads (pumps, compressors, etc) and onsite generation (solar, gen, wind, hydro, etc)
Site plan and single-line diagram, possibly a power study (if available)
Current and future objectives as it relates to:
Cost savings
Resiliency needs and outage history
Investment size and return
Emissions reduction
Snowmaking peak and future peak
CRIES Snow
Key takeaway
A ski area is not a normal commercial load.
It is a seasonal, weather-triggered, power-intensive operation with long periods of unused electrical capacity.
That is why standard energy products may miss the strategic value of a ski area, and why a ski-area-specific strategy can create value from the same load profile that conventional developers often avoid as credit risks.
