En­ergy Pro­duc­tion

Element - - BUSINESS -

Auck­land keeps its lights on al­most en­tirely us­ing en­ergy sources out­side of its re­gion. Even the nat­u­ral gas plants at Green­mount and Rosedale in south Auck­land both use nat­u­ral gas sourced from Taranaki. The Coun­cil’s Plan ac­knowl­edges that there is greater scope for re­new­able elec­tric­ity gen­er­a­tion in the form of wind, water, geo­ther­mal and biomass gen­er­a­tion, as well as smaller-scale use of pho­tovoltaic elec­tric­ity gen­er­a­tion from the sun, but for the most part this will be re­liant on tech­nolo­gies still in devel­op­ment.

The Plan states: “All our elec­tric­ity and trans­port fu­els come in along sin­gle sup­ply lines with no re­place­ment routes in the event of dis­rup­tion. This is not just an is­sue for Auck­land, but also for North­land, which re­lies on elec­tric­ity trans­mis­sion through Auck­land. Our sup­ply chain is vul­ner­a­ble to dis­rup­tion from a range of in­flu­ences in­clud­ing ris­ing fuel prices, nat­u­ral dis­as­ters, chang­ing cli­matic con­di­tions and the fail­ure of the na­tional grid.”

The re­sponse is to main­tain and up­grade the cur­rent elec­tric­ity sup­ply lines to im­prove the sys­tem’s re­silience and pre­pare it for th­ese emer­gent tech­nolo­gies once they are ready to go on line. In the mean­time Ge­n­e­sis En­ergy has been granted var­i­ous re­source con­sents for the es­tab­lish­ment, con­struc­tion, op­er­a­tion and main­te­nance of a gas-fired power sta­tion at Rod­ney to help meet grow­ing de­mand and im­prove sup­ply se­cu­rity to the up­per North Is­land.

Clearly, Auck­land will re­main a long way from en­ergy self-suf­fi­cient for a long time to come.
