This compares to a high of nine hours back in March
New figures from the United Nations show residents in the Gaza Strip are receiving less than five hours of electricity a day.
The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) has published new data for the Occupied Palestinian Territory.
It shows that the hours of electricity supplied to the region has dropped from a high of nine hours, last seen on March 15th, to just three hours now.
A breakdown shows the majority of megawatts per day come from Israeli lines, with around half coming from the Gaza power plant.
The OCHA says: "For the past decade, the Gaza Strip has suffered from a chronic electricity deficit, which undermined already fragile living conditions.
"The situation has further deteriorated since April 2017 in the context of disputes between the de facto authorities in Gaza and the West Bank-based Palestinian Authority.
"The ongoing power shortage has severely impacted the availability of essential services, particularly health, water and sanitation services, and undermined Gaza’s fragile economy, particularly the manufacturing and agriculture sectors.
It says the information is provided on a daily basis by the Gaza Electricity Distribution Company (GEDCO), the official body in charge of electricity supply in the Gaza Strip.
The new figures come amid new tensions over the US decision to recognise Jeruslalem as Israel's capital.
Earlier this week, the Organisation of Islamic Cooperation (OIC) called on other countries to recognise a Palestinian state with East Jerusalem as its capital.
The State of Palestine has bilateral recognition from 137 UN member states.
Ireland has yet to recognise the State of Palestine.
