If you live in South Lake Tahoe or on the California side of the basin like Meyers, Markleeville, Tahoma, Tahoe City, Truckee, or Kings Beach, a major change is coming to your electricity—and it could have a direct impact on your monthly energy bills.
Starting in spring 2027, Liberty Utilities (CalPeco Electric) will replace roughly 75% of its current energy supply as its long-standing wholesale contract with NV Energy comes to
an end. This shift marks a significant transition for homeowners and businesses across the Lake Tahoe Basin.
While Liberty Utilities aims to maintain reliability, the reality is that this change could lead to higher electricity rates across the region. For residents throughout South Lake Tahoe, Truckee, and surrounding communities, now is the time to understand what’s coming—and how to prepare.
Understanding the Current Energy Setup in the Tahoe Basin
Liberty Utilities currently serves approximately 49,000 customers throughout the Sierra Nevada region, including:
South Lake Tahoe
Meyers
Markleeville
Tahoma
Tahoe City
Truckee
Kings Beach
At present, about 75% of the electricity supply comes from NV Energy through a long-term wholesale agreement, with the remainder generated from Liberty’s own renewable resources, including solar.
However, NV Energy has confirmed it will not renew this contract after May 2027, largely due to increasing energy demand in Nevada—especially from large-scale developments like data centers.
What’s Changing in 2027?
Once the contract ends, Liberty Utilities will shift to purchasing electricity on the open Western energy market, facilitated by new infrastructure like the Greenlink West transmission line.
This means:
Energy will be sourced through competitive bidding
Prices will fluctuate based on market conditions
Liberty will rely on a broader, less predictable supply network
The utility has already submitted plans to the California Public Utilities Commission (CPUC) to secure new energy providers through a Request for Proposals (RFP).
While this introduces flexibility, it also introduces uncertainty—and potential volatility in energy pricing.
Why Electricity Rates in Tahoe Area Are Likely to Increase
If you’re a homeowner in Tahoe City or Truckee, you’ve probably already noticed that electricity rates in Tahoe and California tend to rise over time. This trend is expected to continue—and possibly accelerate.
Key reasons include:
1. California’s Rising Energy Costs
Over the past decade, electricity rates across California have increased dramatically—often 70% to 100% or more in some areas.
These increases are driven by:
Wildfire prevention and mitigation costs
Grid hardening and infrastructure upgrades
Renewable energy mandates
Increased insurance and operational expenses
2. Market-Based Energy Procurement
Moving away from a stable, long-term contract to a market-based system exposes Liberty Utilities to fluctuating wholesale prices.
When energy prices spike in the Western grid, those costs are typically passed on to customers.
3. Continued Local Cost Pressures
Even if wholesale prices remain competitive, other fixed costs—like wildfire safety upgrades—continue to push rates higher.
What This Means for Residents in South Lake Tahoe, Meyers & Surrounding Areas
For homeowners and businesses in South Lake Tahoe, Meyers, Markleeville, Tahoma, Tahoe City, Truckee, and Kings Beach, the outlook is clear:
👉 Expect continued upward pressure on electricity bills
👉 Prepare for less predictable energy costs
👉 Plan ahead to reduce reliance on the grid
Those who rely entirely on utility power will feel the full impact of these increases.
How Solar Power Can Protect You from Rising Energy Costs
The good news? You’re not powerless.
Installing solar panels in South Lake Tahoe or Truckee is one of the most effective ways
to control your long-term energy costs.
Here’s how solar helps:
Offset Your Electricity Usage
Every kilowatt-hour (kWh) your solar system produces is one you don’t have to buy from Liberty Utilities. As rates increase, your savings increase too.
Lock in Predictable Energy Costs
Instead of being subject to fluctuating utility rates, solar allows you to stabilize your energy expenses for decades.
Maximize Tahoe’s Sunlight
Despite snowy winters, the Tahoe region receives strong solar exposure—especially during spring and summer months.
This makes solar a highly effective solution for homes in:
Tahoe City
Kings Beach
Tahoma
Truckee
Why Battery Storage Is a Game-Changer in the Tahoe Basin
While solar panels are powerful on their own, pairing them with battery storage takes
your energy independence to the next level.
1. Peak Energy Savings
Store excess solar energy during the day and use it at night—when electricity rates are often higher.
2. Protection from Time-of-Use Rates
As Liberty shifts to market pricing, time-of-use (TOU) rate structures may become more impactful.
Batteries help you avoid expensive peak-hour pricing.
3. Backup Power During Outages
In wildfire-prone areas like Meyers and Tahoma, outages are a real concern.
Battery systems provide reliable backup power, keeping your home running when the grid goes down.
4. Greater Energy Independence
With solar + storage, you dramatically reduce your reliance on the utility grid.
Solar Incentives Available for Tahoe Area Homeowners
Homeowners in South Lake Tahoe, Truckee, and surrounding communities may qualify for valuable incentives that make solar more affordable. Talk to your solar installer about programs you might qualify for.
These incentives can significantly reduce upfront costs and improve your return on investment. Check out our blog post that breaks down Third Party Ownership with Tax Equity and Prepaid PPA’s.
Why Now Is the Best Time to Go Solar in South Lake Tahoe & Truckee
Waiting until after 2027 could mean:
Paying higher electricity rates before switching
Missing out on current incentives
Longer payback periods
By acting now, homeowners in Tahoe City, Kings Beach, and Meyers can:
✔ Lock in lower energy costs sooner
✔ Maximize available incentives
✔ Increase property value
✔ Gain energy security before rate increases hit
The Bottom Line: Prepare Now for Future Energy Costs
The upcoming 2027 transition is largely out of local control—but your response to it isn’t.
For residents across:
South Lake Tahoe
Markleeville
Meyers
Tahoma
Tahoe City
Truckee
Kings Beach
…the most effective strategy is to reduce dependence on the utility grid.

Frequently Asked Questions (FAQ)
Will electricity rates really increase after 2027?
While exact rates are not finalized, historical trends and the shift to market-based procurement strongly suggest continued increases.
Is solar worth it in snowy areas like Truckee or Tahoe City?
Yes. Snow typically melts quickly off panels, and the region still receives strong annual sunlight, making solar highly effective.
How much can I save with solar in South Lake Tahoe?
Savings vary, but many homeowners significantly reduce or even eliminate their electric bills—especially when adding battery storage.
Do I need a battery with my solar system?
Not required, but highly recommended. Batteries provide backup power, maximize savings, and protect against peak pricing.
How long does it take to install solar?
Most residential installations are completed within a few weeks after permitting and design approval.
Are there incentives still available for solar?
Yes. There are federal, state and local programs that can substantially reduce system costs—but availability may change over time.
What happens during a power outage?
Without a battery, most solar systems shut off for safety. With battery storage, your home can continue running during outages.
