Still more to go on so­lar con­nec­tion to meet reg­u­la­tions

Kalgoorlie Miner - - OPINION -

In re­sponse to your ar­ti­cle, (So­lar bill shock for health cen­tre, 27/10) I want to pro­vide more in­for­ma­tion to en­sure your read­ers re­ceive some bal­ance in this de­bate.

The Ngang­ganaw­ili Abo­rig­i­nal Health Ser­vice in­stalled 100kW of so­lar at their premises in Wiluna be­fore agree­ment was reached with Hori­zon Power on the con­nec­tion of the so­lar sys­tem to our net­work and the costs as­so­ci­ated with that.

This is a very large so­lar ar­ray in a very small elec­tri­cal sys­tem (760kW), so it re­quires feed-in man­age­ment to pre­vent it dis­rupt­ing re­li­able sup­ply to other cus­tomers or dam­ag­ing our power sta­tion in Wiluna.

Hori­zon Power re­quires all larger cus­tomers to pay their part of the con­nec­tion costs.

NAHS has a quote to con­nect, but has not at this stage ac­cepted that quote.

There have been sev­eral changes to this quote as the de­sign and con­nec­tion re­quire­ments have changed.

In ad­di­tion, the sys­tem the Health Ser­vice has in­stalled re­quires ad­di­tional work to com­ply with WA’s elec­tri­cal safety reg­u­la­tions and the cus­tomer’s elec­tri­cal con­trac­tor has re­quested a num­ber of ex­ten­sions to sat­isfy the re­quire­ments of th­ese reg­u­la­tions.

The in­flam­ma­tory quote in­cluded in the ar­ti­cle from WA Greens MLC Robin Chap­ple, that Hori­zon Power is to­tally in­com­pe­tent, is not sup­ported by the facts.

Mr Chap­ple says it is about con­nect­ing four wires — this is also in­ac­cu­rate — en­gi­neeer­ing de­sign work and anal­y­sis is re­quired be­fore con­nec­tion.

In this case, the in­staller work­ing for NAHS chose to in­stall the pan­els be­fore reach­ing agree­ment with Hori­zon Power and is now blam­ing Hori­zon Power for fail­ing to con­nect even though there has been no agree­ment on price and fur­ther work is re­quired to meet min­i­mum reg­u­la­tory stan­dards.

The feed-in man­age­ment sys­tem en­ables Hori­zon Power to con­trol the out­put from the NAHS sys­tem to pre­vent it trip­ping the lo­cal power sta­tion and the whole com­mu­nity los­ing power.

We must en­sure we pro­tect the in­ter­ests of all of our cus­tomers.

Hori­zon Power must re­tain own­er­ship of the de­vice be­cause it is en­coded with our se­cu­rity pro­to­cols which se­cure our power sta­tions and other in­fras­truc­ture.

Hori­zon Power is sup­port­ive of re­new­able en­ergy, how­ever it needs to bal­ance the needs of those want­ing so­lar with those of non-so­lar cus­tomers as well as tax­pay­ers gen­er­ally.

Hori­zon Power is a very cus­tomer-fo­cused busi­ness and would pre­fer to deal di­rectly with the cus­tomer to en­sure clear com­mu­ni­ca­tion. Craig Ju­lian, gen­eral man­ager Non In­ter­con­nected Sys­tems
