A clever solar energy tariff plan from Western Australian firm

Horizon finds a smart way to price a solar tariff,  REneweconomy, By Giles Parkinson   5 April 2012 Western Australia energy utility Horizon Power has achieved what appears beyond the capabilities of its larger peers in the eastern states, the Victorian and NSW governments and regulatory pricing authorities, and produced Australia’s first differentiated feed in tariff for rooftop solar PV.

Horizon, which services 100,000 residents and 9,000 businesses in towns and communities across the state, beyond the grid located in the south-western corner, is introducing area-specific solar feed-in tariffs which recognise a higher value for solar put back into the grid from remote locations, and a lower value for solar energy fed from near towns and alternative energy sources.

For instance, in remote townships such as Meekatharra, Cue and Wiluna
(and a dozen others), households will receive 50c/kWh for any surplus
energy exported to the grid, more than double what they currently
receive in their 1:1 net tariff. In major towns such as Broome,
Esperance, Exmouth, Port Hedland and Karratha, where the cost of power
is lower, a rate of 10c/kW will be paid. Towns such as Kununurra,
Wyndham and Lake Argyle, which are remote but close to hydro-power
sources, will receive a rate of 16 c/kWh.

All these payments – described as a “renewable energy buyback” – will
replace the 1:1 net tariffs that Horizon currently has in place and
will change automatically from July 1. And all these payments will be
over and above the mandated state tariffs,..
In regional WA, demand for solar PV has been so great that it has
created other network issues, and Horizon was forced last year to put
caps on the amount of solar PV that could be installed in some towns
such as Carnarvon and Exmouth. However, it has now introduced
“generation managed” systems, which allows them to control the amount
of solar PV being put into the grid at any one time, and drop some
systems out if it causes a voltage surge.

“Like other utilities, Horizon Power has been grappling with the
challenge of managing customer demand for renewable energy technology
with the need to provide reliable and secure power supplies,” Davis
said. “From 1 July 2012, customers will have the option… of installing
a generation-managed system, that is a system where the output can
either be stored or managed by Horizon Power, in towns where
restrictions are currently in place.”…
