Batteries power cell phones, laptops, and electric cars. Now, according to the Wall Street Journal, “Your next home could run on batteries. A combination of solar power and the rise of residential energy storage paves the way for a new kind of cable cutting” and Tesla could play a major role in it. It turns out that batteries coupled with solar power could completely transform the energy sector. It’s a bet Elon Musk is willing to make and it’s one reason Tesla is changing the way we think about energy.
Tesla’s battery-powered cars get all the press. But Tesla’s battery-powered homes can be a real game changer. “There’s something ruggedly individualistic and inherently American about having batteries in your home. They’re good for keeping power going in a disaster, as customers of the two biggest firms by sales volume in this field, Sonnen and Tesla, demonstrated in the aftermath of Hurricane Irma. And in combination with rooftop solar panels, they free people from total dependence on the grid—a kind of energy cable-cutting that wonks call ‘grid defection.'”
It’s no wonder grid operators are taking notice. In fact, a “radical, battery-enabled rethink of the grid is already happening in Vermont. In partnership with Tesla Energy, Green Mountain Power is offering 2,000 of its customers the opportunity to have a Tesla Powerwall in their home for $15 a month. The 13.5 kilowatt-hour batteries retail for $5,500, but the utility can afford to put them in homes because they help the company save on other grid infrastructure.” Battery-powered homes can be akin to a “virtual power plant for demand response” that could allow the houses to stabilize the grid, lower its carbon footprint, and decrease peak load.

Uptake of home batteries, like Tesla’s Powerwall, is often being driven by a powerful need: renewable energy. “Solar power, especially, tends to generate electricity only at certain times—and it’s rarely in sync with a home’s needs. In some states, such as California and Arizona, there’s an overabundance of solar power in the middle of the day during cool times of the year, then a sudden crash in the evenings, when people get home and energy use spikes. For utilities, it’s a headache. The price of electricity on interstate markets can go negative at certain times, forcing them to dump excess electricity or pay others to take it.”
“This is not a long-term theoretical issue that might happen—this is now,” says Marc Romito, director of customer technology at Arizona Public Service, the state’s largest electric utility. Furthermore, with the growth of electric cars, power demands on the grid will increase even further. Tesla’s strategy: from sun, to home, to wheels — could provide a 360 degree solution which defines a new energy paradigm.
Tesla anticipates a massive shift in the energy business. What trends are driving this shift? The combination of increasing solar coupled with, “Falling [battery] prices also help. Battery pack prices have decreased, on average, 24% a year since 2010. Cheaper batteries… make renewable energy more attractive to home owners. In 2016, solar grew faster than any other energy source, according to the International Energy Agency. At the intersection of these and other trends is a simple fact: For the first time since the discovery of fire, the way humans get energy is set to fundamentally change.”

Utah-based rPlus Energies recently held the groundbreaking ceremony for the Green River Energy Center, a 400 MW solar PV and 400 MW/1,600 MWh battery storage project in Eastern Utah. Tesla Megapacks will be used as the upcoming facility’s battery storage solution.
At 400 MW/1,600 MWh, the Green River Energy Center is expected to become one of the largest solar-plus-storage projects under development in the United States. Once operational, the facility would supply power to PacifiCorp under a power purchase agreement, as noted in a press release.
Utah Gov. Spencer Cox shared his excitement for the project during the Green River Energy Center’s groundbreaking event. As per the Utah Governor, the solar and battery storage system represents a notable step forward for the state’s sustainable energy efforts.

“This project is being built in rural Utah, by rural Utahns, and for all of Utah. When rural Utah thrives, the entire state prospers. Today, we’re not just breaking ground—we’re building a future of affordable, abundant energy in Utah,” the official noted.
The Green River Energy Center secured over $1 billion in construction debt financing earlier this year. The facility is also expected to create about 500 jobs, many of which will be filled by local workers. With this in mind, the solar and battery farm would likely prove to be a boost to Emery County’s economy, enhancing tax revenue, strengthening public services, and offering long-term employment opportunities for the area’s residents.
Sundt Construction will serve as the project’s contractor, EliTe Solar will supply the solar modules, and Tesla will provide the battery storage system for the project. Luigi Resta, President and CEO of rPlus Energies, noted that the Green River Energy Center is special because of the entities that have worked together to make the facility a reality.
“It’s the partners that make this project special, that have made this monumental project possible. From our equipment providers to the onsite talent, and the support of the local and regional community, we owe this project’s success to each of you,” he stated.

Tesla Energy is losing a director who brought Autobidder, a real-time trading and control platform that provides value-based asset management and portfolio optimization, to the company.
Rohan Ma, who has been at Tesla for just under eight years, announced he would depart the company on LinkedIn, aiming to take on a new opportunity elsewhere.
Ma posted:
“After eight years at Tesla, this will be my last week. It was a ride of a lifetime! Today, Tesla Energy is thriving and I can confidently say it’s in the best position it has ever been in to drive impact toward the original mission I signed up for. I’m proud to have contributed over the years to where it is now, and will be cheering the team on from the sidelines as they carry the torch forward and continue to relentlessly solve problems at the frontier of the energy transition.”
Ma started as the Senior Manager of Energy Optimization at Tesla back in November 2016. After four-and-a-half years at the position, he then moved on to a new role as the Director of Energy and Software Optimization. He has been in that role for over three years.
The exit of Ma is the latest in Tesla’s tough year in terms of losing high-level employees.
Earlier this year, as a part of widespread layoffs, Tesla eliminated up to 20 percent of its workforce and people like Rebecca Tinucci, who was the company’s Senior Director of EV Charging.
Tesla also lost Rohan Patel, Vice President of Global Public Policy and Business Development, and Martin Viecha, who was Head of Investor Relations, are just a few notables to depart.
Autobidder
Tesla’s Autobidder platform helps owners and operators make money by autonomously monetizing battery assets. It is a real-time trading and control platform that maximizes revenue according to business objectives and risk preferences.

Autobidder already has hundreds of megawatt-hours under management and continues to scale. It is hosted on Tesla’s secure cloud infrastructure that is engineered to handle large and complex computations.
Without Ma’s expertise, Autobidder would likely not be involved in Tesla’s Energy division at all, and although it is not frequently discussed, it is still a major part of the business’s growth over the past several years.
