Ideol turbine still waiting for grid connection

Global Wind Energy

FRANCE: The country's first offshore wind turbine is still waiting to export power to the grid after a fault in the transmission connection.

A "technical problem" affecting the export cable from the SEM-REV test site, where the Floatgen floating platform was recently installed to much fanfare, was identified about two years ago, site owner Ecole Centrale de Nantes (ECN) has admitted.

Although the fault was first discovered in 2016, it took a long time to identify exactly where the problem was, a source close to the test site explained.

It eventually turned out to be a fault in the junction box between the 20km-long export cable, installed in 2012, and a 400m-long extension added in 2015 when the hub – to which up to three demonstrators can be connected – was also installed, the source added.

When the Floatgen demonstrator was installed at the site in May, Ideol announced that "the connection to the export cable and to the power grid will be scheduled in the very near future after a last series of tests."

According to ECN, however, the plan was always for the final connection to take place in the summer.

Once connected, Floatgen will undergo a series of tests at the SEM-REV site for a period of at least two years.

Renewable energy generated 104% of Portugal's electricity consumption in March

Global Wind Energy

Most of the energy came from wind and hydroelectric power

Portugal generated more renewable energy than it needed in March, for the first time in at least 40 years.

Energy from renewable sources made up 103.6 per cent of mainland electricity consumption last month, according to data from the country’s power grid operator REN, although fossil fuels were used to occasionally top up the electricity supply.

The second-highest level of 99.2 per cent was set in 2014.

A report by the Portuguese Renewable Energy Association and the sustainability group ZERO, said the achievement was an “example” of what the future holds for renewable energy.

“It is expected that by 2040 the production of renewable electricity will be able to guarantee, in a cost-effective way, the total annual electricity consumption of mainland Portugal,” it said.

“These data, besides indicating a historical milestone in the Portuguese electricity sector, demonstrate that renewable energy can be relied upon as a secure and viable source with which to completely meet the country’s electricity demands.”

Weather conditions in Portugal also helped production from renewable sources, as wet and windy weather meant output from hydroelectric dams and wind turbines was high.
