he Greek electrical system has hit a new milestone, after running completely on “clean” renewable energy for the first time.
Renewable energy sources covered Greece’s electricity demands for about five hours last Friday, the Independent Power Transmission Operator, or IPTO, said. Renewables also posted a new record that day, reaching a peak of 3,106 megawatt hours (MWh) of electricity.
The company, which owns and operates the Greek electrical transmission system connecting power plants with customers, says the achievement will open the door to making its energy mix greener in coming years.
Greece relies on a range of sources for electricity, with no one source accounting for more than 50%. In August of 2022, natural gas and renewable sources, such as wind and solar, accounted for the most power. IPTO also draws electricity from hydropower, as well as from lignite or “brown coal,” one of the dirtiest fossil fuels.
