A plan to stockpile coal at Huntly Power Station is a step closer

The Commerce Commission's proposing approving a deal letting major power-companies share the cost.

It says it will improve security of supply, and in the short term, lower wholesale prices.

Major Electricity Users' Group Chief Executive, Karen Boyes, says that's a positive step, but far from enough.

She says they need more than the Huntly unit to keep the country stable through periods of dry weather, as well as wet.

The Government's due to unveil an energy sector plan tomorrow morning.
