The Hawaiian Volcano Observatory's Steve Brantley declared the lava initially appeared to have been diverting from the facility.
Leilani Estates, a small residential neighborhood on the Big Island of Hawaii near the town of Pahoa, has been at the epicenter of the Kilauea volcanic eruption for the past three weeks.
David Mace, a spokesman for the Federal Emergency Management Agency, said: "I think it's safe to say authorities have been concerned about the flow of lava onto the plant property since the eruption started".
However, a spokesperson for the geothermal plant told Hawaii News Now the lava is actually only 40 metres away from the nearest well, but said there was no indication any of the wells will be breached. We monitor for hydrogen sulfide and sulfur dioxide on a continuous basis, " Kaleikini said.
Officials previously moved 50,000 gallons of potentially toxic gas offsite and capped the wells on the property to prevent releases of additional gas if lava enters the wells.
An old warehouse near the PGV has already been destroyed, according to Hawaii's Civil Defence. The flow is on Pad E of the Puna Geothermal Venture, heading from west to east.
Fissure 8, one of the westernmost active fissures on Kīlauea Volcano's lower East Rift Zone, reactivated during the overnight hours of May 25-26, with chaotic bursts of gas and lava spatter.
