In addition to the complexity of integrating advanced energy technologies such as geothermal into a century-old historic building, the project was made even more complicated by the need to move a 12,000-lb drilling rig below grade into a subfloor below the basement with no elevator service.

Fervo Energy has construction underway on 631-acre project, including on 148 acres of public land, and announced two purchase agreements with Southern California Edison for 320 MW of eventual output.

Drilling rigs are punching the last of 320 boreholes this summer on a full city block along the East River, where Lendlease is building a 789,000-sq-ft mixed-use complex of five buildings in Brooklyn’s Greenpoint neighborhood.

A 471,000-sq-ft residential high-rise in Brooklyn’s Coney Island will get sustainable heating and cooling from underground wells when open in 2024.

Advancements in enhanced systems could allow geothermal power plant construction just about anywhere in the U.S., agency officials say.
