CODC explores solar plan

Malcolm MacphersonCentral Otago could become one of the country's first "solar centres" through a Central Otago District Council (CODC) scheme that could see ratepayers able to pay off solar hot-water systems through their CODC rates.

"It can be done; it's being done elsewhere in the country and we're looking at it seriously," Central Otago District Mayor Malcolm Macpherson said.

Nelson City Council this week introduced the first scheme of its kind in New Zealand, where homeowners can get a loan to cover the cost of installing a solar hot-water system and take 10 years to pay it off as part of their rates bill.

Dr Macpherson said the details of any Central Otago scheme would be similar, where the CODC would "act as a bank" and pay the costs of installing the solar hot-water systems, which homeowners would pay back over a period of time.

An Energy Efficiency and Conservation Authority (EECA) subsidy would probably also be available as part of the scheme, he said.

Dr Macpherson said he had been "talking to Nelson" about its new scheme, and already had meetings in Alexandra with several private providers who were involved in installing the solar hot-water systems.

Solar energy had become much more affordable and reliable and it was an ideal time to investigate a scheme for Central Otago, Dr Macpherson said.

"It's ideal for Central Otago. I think it should be a no-brainer for us."

He expected the CODC would decide "reasonably quickly" whether to adopt a scheme.

"In the next 12 months we'll know whether there will be something going or not."

Dr Macpherson said savings for homeowners in Central Otago with solar hot-water systems could be substantial - for most of the three-month summer season homeowners would spend no money at all on hot-water heating, and for another five months they could expect to pay "hardly anything".

Electric heating of water would "kick in" during periods when there was not much sun.

Solar Hot Water Systems

• At present, solar water heaters (including the cylinder) typically cost between $4000 and $8000 to get installed.

• It is estimated that, for an average household, an effective system will: provide between 50 to 75 per cent of annual hot water needs; cut about 2200kWh from annual electricity use; and provide savings of $350 to $450 a year.

lines companies ...

In the US there's a large economic incentive for power companies to save energy rather than increase the amount that's being used - that's because they have to upfront the cost of new power plants themselves. It's cheaper to get your customers to use a bit less as the number of customers rise and still rake in the same profit than it is to borrow the money to build a new power plant that won't start paying off its capital investment for a decade or so.

Sadly one of the side effects of splitting up the power system the way we have is that DCC's line company has no incentive to get us to use less as it would just means that they would earn less.

No chance the DCC will be innovative

Like the recent power price hikes because of line charges, the DCC need their lines company to put prices up again to get more money for the stadium from everyone who uses power. If we all get solar water heaters, then there's less oportunity for us to be fleeced by DCC's line company.

stadium vs innovation

Sorry Amanda K we have a population of 120,000 but only 53,000 ratepayers - so as you can see 2/3 of the population will not be paying for the stadium ... big difference..

We've got a stadium to pay

We've got a stadium to pay for, that might be something to do with it. 120,000 of us have to pay for a $260 million plus drain on the city for the next 30 years. That may be why your good suggestion will not be even considered. Unless we vote the ones who put us in this position out, of course. Take a bow our 11 pro stadium councillors.

Solar or oil

Why can't the DCC be innovative like this? Instead of exploring the oil business why don't we explore solar power or some form of energy that would actually help our citizens. Everyone in the world is trying to divest from the oil business and build subsistence infrastructures. There are some amazing minds in our country - why are we not as a city investing in our future like this?
