Netherlands' largest power company wishes to connect new solar parks to 75% of their peak capability

• Liander claimed its brand-new strategy may cause cost savings varying from EUR1.4 billion to EUR1.8 billion. Feasible losses for PV power producers are approximated at an optimum of 3% of their electrical power production per year. If applied, this new action would certainly push PV project designers to rely on underdimensioned inverters.

Dutch power company Liander has applied several measures in current months to increase grid capacity in numerous Dutch areas affected by grid restraints, which are preventing extra renewable resource plants from coming online. These consist of the deployment of two large tranformers and the application of congestion management to a traffic jam in the grid.

This week, it additionally revealed its objective to link only solar parks to 75% of their peak capacity. "In this method, we can link more manufacturers of eco-friendly electrical power as well as save up to EUR400 million euros in social prices in our service area," Liander mentioned. "By connecting solar parks to 75% of their peak ability, we can make use of the electricity grid a lot more efficiently."

The company included that if it had to expand the grid to host more solar, financial investments ranging between EUR1.4 billion and EUR1.8 billion would certainly be needed. It additionally described that these high investments would certainly give reasonably little advantages in fixing the grid congestion issues.

Liander quotes possible losses for PV power manufacturers at an optimum of 3% of their electrical power production annually.

Dutch solar analyst Peter Segaar told pv magazine that Liander's strategy, which would apply only to recently linked solar parks, is related to the commonly exercised "underdimensioning" of the inverters' A/C connected power with respect to the DC generator capability beyond the inverter devices. "This is rational due to cost reduction, need for much less powerful inverters than essential," he said. "Completely brand-new, nonetheless, is the grid driver's desire to take care of beforehand the ratio in between A/C and also DC ratings of the projects prepared."

It remains unsure exactly how this plan could be implemented, he added. "It would imply that it is purely forbidden to exceed the organized DC capability of the generator, or financiers need to currently know in advance what exactly their AC ability of the inverter battery will certainly be," he stated. "And they normally don't understand."

Segaar clarified that the strategy can just be applied if the existing SDE+ program for large renewables were modified. "These guidelines, however, are currently far as well intricate for lots of smaller investors, as well as making them more made complex would certainly not be excellent."

In late May, the Dutch government stated that grid drivers were not obliged to make up the proprietors of solar roofs whose selections are separated due to issues with grid capacity and also voltage quality. According to Segaar, planetary system disconnections are frequent just in densely inhabited areas when systems include cable televisions that were created for usage just. "Many PV systems on such lines create voltage boosts, by the way over the established norm," Segaar said at the time.

In late January, Liander as well as grid operator Enexis said there was restricted capacity available for renewables projects-- mainly huge range solar-- in parts of those northeastern districts.

Liander expects to have around 6 GW of solar ability on its grid by 2023.
