I have rooftop PV that can be very closely monitored, and even on a very sunny day, there are dozens of spikes and valleys in the production. With DG it evens out. With a huge solar array it causes instability. <br /><br />Here on Kauai KIUC tried to buffer this with batteries, but within less than 2 years the 2,000,000$ battery bank was pau. They bought another one for their next array, this time for 8,000,000 and will still have to replace the first one.<br /><br />Also, with DG the utility has no land-lease costs, no maintenance, and especially no purchase costs. And on Kauai they even get away with a wholesale-retail ratio of 1:3 (meaning we need to feed 3 kWh into the grid in order to get 1 kWh back at night) - This is a change that's most likely coming to all of the islands, HECO is moving away from net-metering too, and the PUC is likely to approve it as it's working so well on Kauai.Sonjahttps://www.blogger.com/profile/01379148591739859973noreply@blogger.com
