Renewable Energy Law has weakened the German electricity grid

May 13, 2012

The Renewable Energy Law was introduced 12 years ago in Germany. It prioritises the use of “green energy”. What was thought to be a way of helping the introduction of new technology and fulfilling a political agenda has backfired and has led to a severe weakness of the electricity grid and the second-highest electricty price in Europe.

The Law leads to large conventional coal and gas plants leaving the grid far too early  and these are the only plants which can guarantee a stable supply of power. This in turn has led to many of these plants being decommissioned prematurely since they were being forced to operate at uneconomic levels of loading. They are then no longer available to compensate when the wind does not blow or at night or on cloudy days as wind and solar power generation fluctuate wildly.

The hidden costs of renewable power are now being revealed and an entirely new market for “balancing power” has appeared. The “balancing power” – nearly always gas-fired  – is just to compensate for the inherent unreliability of wind and solar.  For every 100 MW of renewable capacity added around 70 MW of (mainly) gas-based balancing capacity has to be added to ensure a stable and steady supply of power. With subsidies and “balancing” costs added to the direct cost of building wind or solar plants, the actual costs of renewable power have been exorbitant and have contributed significantly to the increase of electricity prices to the consumer. Germany now has the second highest consumer electricity price in Europe (second only to Denmark with its profligate use of subsidised wind turbines)

The German Federal Network Agency has issued a report warning of the dangers during the coming winter. Daniel Wetzel of Die Welt writes (translation from GWPF – Philip Mueller):

Last winter, on several occasions, Germany escaped only just large-scale power outages. Next winter the risk of large blackouts is even greater. The culprit for the looming crisis is the single most important instrument of German energy policy: the “Renewable Energy Law.”
