New clean energy communities are coming to California. Leading homebuilder KB Homes announced Wednesday it has established what it calls the first all-electric, solar-and-battery-powered microgrid community in the golden state.

KB partnered with the US Department of Energy (DOE), SunPower, Scheider Electric, and Kia, among others, to test the new energy-efficient homes at several of its new communities.

The new all-electric, solar-and-battery-powered micro-communities are located at Oak Shade and Durango, part of KB Homes Shadow Mountain master plan in Menifee, California. However, these are not your typical energy-efficient homes with added solar panels.

The houses involved in these communities are equipped with backup battery storage, bidirectional electric vehicle charging capabilities, and perhaps most importantly, are interconnected, creating a resilient energy network.

When combined, these technologies establish a self-supporting energy network capable of powering a neighborhood during a power outage.

How all-electric, solar-and-battery-powered community works

Each home in the microgrid community will come fitted with the following:

  • SunPower Equinox solar system
  • A 13 kWh SunVault battery storage
  • Rheem® ProTerra® hybrid electric heat pump water heater
  • Carrier® high-efficiency two-stage heat pump
  • Schneider Electric D Energy Center Smart Panel

Individual solar panels will harness energy from the sun and then store it in powerful batteries to serve as backup. In addition, community solar panels are connected to a 2.3 MW battery to complement the network’s power supply.

On top of this, all houses will come equipped with electric wiring for EV charging, while some homes will feature Wallbox chargers. Homeowners can enroll in SunPower’s Virtual Power Plan (VPP) program, which allows them to utilize their EV chargers, battery storage, and other energy solutions to balance the grid load while demand is highest automatically.

Over 200 all-electric homes will be solar-powered, with added battery storage while connected to a community microgrid. As a result, the communities are power-outage resistant, according to SunPower, serving as a model for the future of home development.

Electrek’s Take

Microgrids are not a new invention. They have been around for some time but are primarily used at industrial sites or extensive commercial developments. However, with residential energy use accounting for about 20% of GHG emissions in the United States, the community KB Homes and its partners have built should serve as a blueprint for new home building.

Furthermore, extreme weather is the number one culprit behind blackouts in the United States. According to a recent study from Climate Central, around 83% of reported major outages were from weather-related events. More importantly, the number of blackouts due to weather has risen roughly 78% in the past 10 years.

Building grid-resilient communities using solar, battery storage, and all-electric components can significantly reduce the impact.

For example, Babcock Ranch, a “solar-powered community” in Florida 12 miles from Fort Meyers, had water, electricity, and internet, while over 5 million others were not as fortunate after Hurricane Ian plowed through the state.

Last year, the DOE announced $61 million in funding to create ten “connected communities” capable of interacting with the grid to optimize energy consumption and reduce carbon emissions.

According to a DOE study, grid-interactive efficient buildings (GEBs), such as those introduced by KB Homes in California, could save $18 billion in power system costs while cutting 80 million tons of CO2 emissions each year.

On an annual basis, this is more emissions than 50 medium-sized coal plants or 17 million vehicles. The first two communities in Alabama and Georgia have used around 42% to 44% less energy than an average all-electric home.

It’s proven these microgrid communities work. Now it’s time for federal officials to step up and accelerate this transition. It will be less costly in the long run.

The Eastern US's first CFI-funded EV charging hub comes online

The first EV charging hub funded by the Charging and Fueling Infrastructure (CFI) Program in the Eastern US is now online in Deerfield, Massachusetts.

The town installed the region’s first DC fast chargers (four ports), along with four Level 2 chargers, at 59 North Main Street in South Deerfield.

These new charging stations, funded with $2.46 million from the CFI program, are conveniently located near Interstate 91 in Franklin County, the most rural county in Massachusetts, which serves drivers from Connecticut up to the Canadian border.

The hub also features local and regional bus stops and designated bike lanes with secure onsite bike racks. The chargers are meant to cater to everyone: from local residents and visitors to municipal EVs and commercial vehicles that service the region’s businesses, like those in food and beverage manufacturing.

Gabe Klein, executive director of the Joint Office of Energy and Transportation, sees this as a model for future projects:

Multi-modal charging hubs in communities are key to giving more people the choice to ride and drive electric. The Town of Deerfield is showing leadership in building out convenient charging infrastructure that brings new transportation choices to rural and disadvantaged communities while supporting local commerce.

In recent years, Deerfield has experienced increased climate change-driven flooding from nearby rivers, including the Deerfield River, the Connecticut River, and the Bloody Brook. The project incorporates environmental engineering designed to mitigate and adapt to the effects of flooding and climate, including the installation of permeable asphalt and rain gardens, planting of native trees, grasses, and shrubs, and the creation of new greenspace in the center of Deerfield.

The Biden-Harris administration’s CFI Grant Program is expanding EV infrastructure nationwide. It offers grants for projects that complement and expand upon the initiatives of the NEVI program in urban, rural, and disadvantaged and low-income communities. So far, the CFI Grant Program has allocated over $1 billion to nearly 100 projects across the US, encouraging private investments and expanding the EV charging network to make EV ownership more practical and convenient.

Kia's new low-cost EV4 was just spotted in the US for the first time

Kia’s upcoming EV4 electric sedan was just spotted testing in the US for the first time. The low-cost EV is expected to make its big debut by the end of the year. Here’s a look at the new model.

The EV4 will round out Kia’s new “EVs for all” master plan launched last year. Kia showcased three new models, the EV3, EV4, and EV5, during its first annual EV Day in October 2023.

During the event, Kia outlined its new global strategy to “lead and accelerate the EV revolution” with a wide range of models priced from $30,000 to $80,000.

Kia plans to rapidly expand its lineup with a series of smaller, lower-priced models. It launched the EV9, its first three-row electric SUV, which is already proving to be a hot seller in the US. Starting at under $55,000, the EV9 is still a great deal compared to others in its class, but Kia plans to go even lower.

The EV3 and EV4 are expected to be among the most affordable electric vehicles when they arrive in the US.

Kia’s new EV4 is now testing in the US

Ahead of its official debut, Kia’s new EV4 sedan was recently caught driving on US streets for the first time.

The latest image from KindelAuto doesn’t reveal much more than what’s been shown in the past, but the fact that it’s now testing in the US is significant.

Kia’s EV3 is already on sale in Korea, starting at around $30,000 (42.08 million won). Earlier this week, the company said its new compact SUV is now available across Europe, starting at around $38,000 (36,000 euros) with a “segment-leading range” of up to 375 miles (WLTP).

Next up will be the EV4. Kia is expected to officially reveal the new EV by the end of the year, with deliveries starting in 2025. It could be as soon as next week at the 2024 LA Auto Show.

The interior will feature Kia’s advanced new ccNC infotainment system with dual 12.3″ navigation and driver display screens. An otherwise minalimalistic design is expected inside.

Kia’s EV4 will also be available in a hatchback variant. Although the hatch is likely aimed at European buyers, it was also recently spotted testing in the US for the first time.

We will learn official prices closer to launch, but the EV4 is expected to start at around $35,000 to $40,000.

Kia is teasing five new vehicles for the US, at least one being a new EV, that will debut at the LA Auto Show next week. Will it be the EV3? EV4?
