Operator Ormat Technologies Inc last week said there was no above-ground damage to the plant, but it would have to wait until the situation stabilised to assess the impact of earthquakes and subterranean lava flows on the wells.
Kilauea rumbled back to life on May 3 as it began extruding lava and toxic gases through a series of cracks in the ground on its eastern flank, marking the latest phase of an eruption cycle that has continued almost nonstop for 35 years.
"Hawaiian Volcano Observatory reports that lava from several fissures continues to advance toward the Kapoho area", a Civil Defense message said, referencing an area that was devastated during a 1960 eruption.
Officials said the lava destroyed the electric utility's equipment on the highway which led to power losses at the Vacationland and Kapoho Beach lots.
Despite evacuation orders for the area, some residents returned.
As of Friday, lava has destroyed 82 structures, including 37 homes. If these lava flows reach the intersection of highways 132 and 137 a large area along the coast and highway 137 will be cut off and become completely inaccessible.
Only two of the fissures are still pumping lava: #8 and #24.
"It's hard to get to the center, which is the hottest portion of the fountain", Stovall said.
In Hawaii's East Rift Zone, where Leilani Estates and Lanipuna Gardens are located, "additional ground cracking and outbreaks of lava in the area of the active fissures are possible", the USGS said.
After weeks of scientific updates on the volcano, the U.S. Geological Survey took a lighter tone as it responded to a question on Twitter about whether it would be safe to roast marshmallows over volcanic vents. Wind conditions for Wednesday were forecast to result in widespread vog - or volcanic smog- over the Big Island.
The National Weather Service said the wind could carry ash to other locations.
Although the haze does not contain sulfur dioxide or other toxic chemicals, a NWS official told NPR the particles in the air can still be harmful to people with sensitive respiratory systems. The facility produces roughly one-quarter of the Big Island's daily energy supply. Hundreds of people have been ordered to leave the vicinity of one of the world's most active volcanoes in its biggest eruption cycle in a century. More than 2,000 acres of land have been smothered by lava and about 200 people are staying in emergency shelters.
