Excess Solar generation - not grid connected (G-59)

Aneysha Minocha
Hi All,


We are working with commercial premises that installed Solar PV in the days of the Feed-in-Tarriff. These sites have excess solar generation being measured through a channel, but there is no export from site (not G-59 connected) and the customer is on a deemed Feed-in-Tariff. From the data, there seems to be a high proportion of "excess" / "export" energy from sites.


Question - if the sites are not consuming the excess energy and thet are not set up for grid export - where is this excess energy going?


Would appreciate your valuable input please.

Thank you!

    Export in principle seems best idea providing local switchgear can support, i image power will fluctuate , perhaps suggest the power genrated is profiled , then connectivity sized for maximum input . ie; transformers and power factor correction, which may need to be investigated how the co it may only be 100 KvA swich gear for example  . When I did multicycle stuff for a  HVDC  import experiments  and conversion to AC from France  many years ago the industrial connectors overheated and it was rendered unusable ie; it blew up.  The other possibility is to work with a water company to pump water for storage , relatively complex numbers but currently battaerise require mainetnace every 3 - 5 years very poor in my personal opiniion.
