MCY Mercury NZ ( MRP Mighty River Power)

.....Not sure if roadside lighting consumes a large amount of power relative to other usages like industrial or household.

I found a paper (PDF File) that shows all street lighting in NZ amounts to less than 1% of various distribution companies revenues (page 21/25)..... and most accounts a high % of the bill is fixed so I now understand the slow uptake to LED street lighting...and what you say Antipodean about refits.

The paper also shows some insight into the NZ Power Market structure and how future technology may inpact on this structure, especially when it comes to methods of billing major customers...interesting reading to fill in ones time
