Description:
Provides a neutral overview of the main solutions available to ski areas.
What you’ll learn:
- Where efficiency, controls, generators, solar, and storage fit
- Which strategies address cost, resilience, or operational flexibility
- Why no single solution fits every ski area
Why this matters
Energy projects are often sold one solution at a time.
A solar developer talks about solar. A battery vendor talks about batteries. A generator company talks about generators. A controls company talks about controls. An efficiency vendor talks about reducing consumption.
All of those tools can be useful.
None of them should be the starting point.
For a ski area, the starting point should be the problem the mountain is trying to solve.
Is the problem cost?
Is it curtailment?
Is it lack of snowmaking capacity?
Is it backup power?
Is it power quality?
Is it lack of capital?
Is it an underused interconnection that could earn revenue?
The right strategy depends on the answer.
Efficiency and equipment upgrades
Efficiency is usually the cleanest place to start because it reduces waste.
At a ski area, efficiency may include pump upgrades, compressor optimization, variable frequency drives, lighting, building controls, HVAC improvements, refrigeration upgrades, and better sequencing of snowmaking equipment.
Efficiency can reduce consumption and sometimes reduce peaks. If the mountain still needs to run a large snowmaking load during a cold window, the peak may remain high even after efficiency improves.
That means efficiency should be evaluated as part of the strategy, not confused with the entire strategy.
Controls and data
Controls are often underappreciated.
A ski area cannot manage what it cannot see. Live data from meters, snowmaking systems, generators, solar, batteries, and major loads can help operators understand what is actually driving cost and constraint.
Controls may also allow the mountain to sequence loads, simulate battery dispatch, validate demand reduction, and prepare for a larger project.
This is why a controller or metering-first approach can be useful before making a major capital decision. It turns assumptions into evidence.
Generators
Generators are familiar to many ski areas.
They can provide backup power, support critical operations, and help the mountain ride through outages or utility constraints. In some cases, existing generators may be part of a larger microgrid strategy.
But generators also bring fuel cost, maintenance, emissions, permitting, noise, runtime limitations, and operational responsibility.
They are usually strongest when used as a resilience tool, a bridge asset, or part of a controlled system. They are weaker when treated as the only long-term answer to rising demand charges.
Solar and wind
Onsite generation can be valuable, especially where land, roof space, wind resource, utility rules, and incentives support it.
Solar can reduce energy charges and provide a source of clean generation. Wind may be possible at some mountain sites, but it is highly site-specific and requires careful evaluation of resource, permitting, interconnection, maintenance, and public acceptance.
The main caution is timing.
Solar generation does not automatically match snowmaking peaks. If the highest snowmaking demand happens at night or during cold winter periods with limited solar output, solar alone may not reduce the demand charge that matters most.
That does not make solar irrelevant. It means solar may need storage, controls, or a tariff strategy to contribute meaningfully to the ski area’s biggest pain point.
Battery storage
Battery storage can reduce demand charges by discharging during peaks. It can provide backup power for critical loads without the need for fuel. It can store onsite generation and from a resilient microgrid through extreme weather. It can create revenue when it participates in utility programs or wholesale markets where allowed.
But storage has to be sized around the real use case.
A short-duration battery may help with a short peak or market program for a front-of-the-meter developer. A long-duration system is needed for extended snowmaking windows, utility curtailment, or resilience. The difference matters.
Microgrids
A microgrid is not just a battery.
A microgrid is a coordinated system of loads, generation, storage, controls, and protection that can operate in a managed way. In some cases, it may be able to island from the utility and support your operations during outages.
For ski areas, microgrids are most relevant when the problem is not only bill savings but utility curtailment.
If the mountain needs to make snow through curtailment, protect pumps and pipes during outages, support lodges as emergency spaces, or manage multiple assets together, a microgrid may be the better frame.
Tariff, supply, and contract strategy
Not every energy strategy requires new equipment.
Sometimes the first value comes from understanding the tariff, energy supply contract, rate class, demand ratchet, meter structure, or utility program eligibility.
A ski area should understand the bill before it signs a project contract. Otherwise, the project may be solving the wrong problem.
How to choose the right strategy
A useful way to sort options is to ask what job the solution is being hired to do.
If the job is lower energy cost, efficiency and supply strategy may help.
If the job is lower demand cost, storage may be the central strategy.
If the job is resilience, generators, storage, a microgrid may be needed.
If the job is revenue, interconnection monetization, aggregation, and market participation then energy storage and a microgrid with onsite generation may be best.
If the job is snowmaking expansion: then utility capacity, onsite generation, storage duration, and water availability all have to be evaluated together.
Key takeaway
No single solution fits every ski area.
The right energy strategy depends on the mountain’s load, tariff, interconnection, operating constraints, capital structure, and goals.
Start with the problem. Then choose the tool.
