Tesla buys the entire output of a new 140 MW Texas solar farm

Tesla has agreed to buy all the power from a new 140-megawatt solar farm being built in northeast Texas. The farm, called Lumen Farm, is being developed by Zelestra, a renewable energy company. Construction starts in 2027, with the plant expected to go online in 2029. Neither company said what the electricity costs or exactly what it will power, though Tesla has large operations in Texas, including Gigafactory Texas and growing AI computing needs, that could use the supply.

This isn't really a story about your own home upgrades, but it says something about where electricity demand is headed. Zelestra is one of the busiest solar developers in Texas, also selling power to Meta for its data centers. As more big companies lock up solar supply for factories and data centers, demand for electricity — and for the solar farms that generate it — keeps growing in states like Texas.

One detail worth noting: Tesla itself sells solar panels, roofing, and batteries, and is even building a huge solar panel factory near Houston. Yet for its own power needs, it's buying from someone else's farm rather than building one itself, a sign that its solar manufacturing business is still ramping back up after years of being scaled down. None of this changes rebate programs or upgrade costs for homeowners, but it reflects rising demand for electricity and solar power nationwide, including in Texas.
