More life, less carbon.

🌐 Utah is pioneering the future of residential solar energy in America.

In 2020, Rocky Mountain Power, Utah's energy utility, leaped into the unknown. California had been paying Rocky Mountain Power for several years to take the excess solar power that Californians with rooftop solar panels were generating. So much solar energy was produced in the middle of the day when few were at home to consume it that the utilities in California would either ship the energy out of state or just curtail it.

Similar to its counterparts in the Golden State, Rocky Mountain Power provided continuous financial incentives to Utahns to install home solar systems under its net-metering program, which enabled homeowners to sell solar energy back to the utility when it is unused at home.

Seeing its own future in California's fate, Rocky Mountain Power took a different approach. It slashed net-metering rates and introduced financial incentives for homeowners to install connected batteries with their solar systems instead.

It sounds perfectly logical. But perfectly aligning the interests of the energy utility, homeowners, and the companies in the middle, the solar installers, to build a resilient, right-sized renewable energy grid has never happened before, certainly not in America.

Rocky Mountain Power’s plan:

  1. Entice thousands to buy batteries for energy storage alongside solar panels.

  2. Weave these grid-connected batteries to form a virtual power plant to draw upon - instead of natural gas plants - to stabilize and strengthen the grid.

  3. Avoid turning on current natural gas power plants or building new ones.

  4. Thereby keeping energy rates low, cutting carbon emissions, and building more resilience against extreme weather.

The question: Would homeowners go for it?

Even with battery incentives, solar-plus-storage systems were (and still are) expensive. Plus, energy rates have been consistently low in Utah. Then, the interest rate for financing started going up.

The hero: ES Solar

When the changes were made, many solar companies fled the state. Selling batteries was considered next to impossible. But ES Solar, a local solar installer, made the strategic decision to go 100% all-in on learning how to profitably sell, install, and manage residential solar-plus-storage solutions.

Today, in partnership with Rocky Mountain Power, ES Solar has installed 96% of the thousands of solar-plus-storage systems operating in homes across Utah.

Zach Randall, VP of Sales for ES Solar, joins the podcast to share how Utah became the center of solar innovation and what it means for the rest of America as other states emulate the Utah experience to build the future.

Stat of the week: 68

That’s the number of natural gas plants canceled or put on hold globally in the first half of 2023 as the cost of giant batteries began achieving price parity with natural gas as an option for energy grids.

The Leader in Virtual Power Plant batteries is sonnen

Alas, Europe doesn’t just dominate the U.S. in croissants and soccer. The continent is also superior in its adoption of climate technologies. Virtual power plants are about a decade ahead in Germany. The German company sonnen is an industry leader and has been expanding its presence on American soil. Utah’s virtual power plant and others in Vermont and California utilize sonnen batteries and its intelligent software layer.

Tesla Powerwall Batteries are Charging into the Virtual Power Plant Future

Now that the people of Houston are sick and tired of seeing their power down for days whenever heavy rains arrive (looking at you, Hurricane Beryl), help is on the way. A pilot virtual power plant is running through a partnership featuring SunRun, the largest residential solar company in the U.S., and Tesla, whose home battery division is growing fast even though car sales are down. So far, 150 homeowners have signed up.

Electric Ford Pickup Trucks are Building a More Resilient Grid

A few Maryland owners of Ford F-150 Lightning pickup trucks are driving the energy grid into the future. Maryland is piloting the nation’s first vehicle-to-grid virtual power plant. It enables EV owners to use the massive batteries in their cars to power their homes during peak energy hours when the grid is overtaxed and receive compensation.

A Really Big Battery Replaced the Last Coal Plant in Hawaii

Combine 158 Tesla Megapacks into one gigantic battery, and you get Kapolei, a utility-scale battery that’s now operational and instantaneously discharges as much energy as a coal plant. Hawaii pledged to retire its last coal plant by 2023, a goal it accomplished. Colton Ching, Hawaiian Electric's senior vice president of planning and technology, says, “This system is larger as a percentage of the electricity system than any other battery in the world.”

#Vanlife Gets a Battery-plus-Storage Upgrade

It took a former SpaceX engineer van life-ing his way around the country during the pandemic to decide that people living in vans deserve more. So, he founded Grounded. Smart, solar-powered electric vans are hitting the road with enough solar energy to power the interior or charge the vehicle in a pinch.

City Spotlight: Salt Lake City

Utah’s Salt Lake City recovered faster than any other U.S. city from the pandemic and is busier today than before COVID-19 struck. Salt Lake City ranks 8th in WalletHub’s study of the healthiest cities in the U.S. Here is what’s Supercool.

Bike Lanes: Many cycling advocates claim adding bike lanes and removing parking spots improves city commerce. Salt Lake City conducted a study based on its own experience, with data to prove it. With its continually expanding bike network, the city has crossed the threshold to become a great place to bike.

Streetcars: Since entering operation a decade ago, a streetcar line running along a two-mile stretch of the city has spurred $2 billion in mixed-use economic development along its corridor. It’s now set for expansion. Other Midwestern cities like Kansas City are playing catch-up and trying to follow Salt Lake City’s lead.

Net Zero Fire Stations: When on duty, firefighters live at their fire stations. Those lucky enough to work at No. 3 or No. 14 in Salt Lake City are content. They’re the first two net-zero energy fire stations in the country. Each draws more power from the 300 solar panels on its respective roof than it consumes.
