Portugal made headlines in recent weeks by meeting its entire electricity demand from renewable resources for an extraordinary 107-hour run, or nearly 4½ days! Germany followed soon-after on 15th
May when renewables supplied 45.5 gigawatts, or 99.3% of a 45.8 gigawatt total electricity system demand.
The Portuguese record was set with a combination of wind, solar and hydroelectric sources. In the following-linked article, the record is stated as having been achieved with against a backdrop of tiny interconnectors between Spain and France:
Oliver Joy, a spokesman for the Wind Europe trade association said: “We are seeing trends like this spread across Europe - last year with Denmark and now in Portugal. The Iberian peninsula is a great resource for renewables and wind energy, not just for the region but for the whole of Europe.” In 2015, wind power alone met 42% of electricity demand in Denmark, 20% in Spain, 13% in Germany and 11% in the UK.
The German record marked a milestone for Chancellor Angela Merkel’s “Energiewende” policy to boost renewables while phasing out nuclear and fossil fuels. German Power prices turned negative during several 15-minute periods on the day, dropping as low as minus €50 euros a megawatt-hour, according to data from Epex Spot.
