Changing the mega trajectory

Changing the mega trajectory

To help resolve the mega-solar development bottleneck, rules were introduced last year allowing for more curtailment of PV power station output by utilities, with central inverters to be fitted with utility-controlled remote shutdown devices. The rules include the right to curtail PV station output to grid for up to 360 hours per year before having to compensate project owners. Previously, since 2012, if the output was curtailed for more than 30 days in a year – with any unbroken one hour period enough to count as a day – utilities had to compensate project owners. Worse than that, once a utility has reached the maximum capacity it says it can handle in an area, it can begin curtailing PV output without compensation. Japan’s solar irradiance varies greatly from its northern to southern islands. The island of Kyushu in the south, with a near-Mediterranean climate, saw PV pl...
