Western Power, the state-owned company that operates the grid in the south-west corner of Western Australia, is looking to take small communities completely off grid so that it can save money on costly network upgrades and extensions.

I was walking  to a remote lighthouse here on Sheep's Head (South West Ireland) earlier this year ....






..... could not believe that they just installed a new powerline and poles to that little energy user ....

.... hysteria

The character of the light is 3 flashes every 15 seconds. The light is white through the arc 017 to 212. A red sector through the arc 007 to 017 warns mariners of the submerged South Bullig rocks, off Three Castle Head to the south.

The source of light is a 100 Volt 150 Watt electric lamp. The light shines through a 800mm dioptric drum lens which gives a light intensity of 59,000 candelas in the white sector, with a reduced intensity of 15,000 candelas in the red sector because of the red filters. This provides a nominal range of 18 miles in the white sector and 15 miles in the red sector.

Billi ....... I could kiss you!

I've spent the week arguing with a fantasist on a MSE thread, who claims PV and storage won't work, even in Australia. It's taken me all week to convince him that the UK grid doesn't 'only' cost 10p/day as he was only considering National Grid and transmission charges, whilst not aware of the 20p+ distribution costs. His argument is that the grid is simply too cheap to warrant off-grid storage, even in Australia.

Anyways, whilst discussing industrial scale storage costs he said (made up) that these would be 80/MWh or worse, I referred to some posts of yours giving details of a 62kWh battery and a 25kWh battery with costs of around 3.5p to 4p/kWh ...... he said this probably wasn't true ....... not sure if he was calling me (or you) a liar.

So you can imagine my face when I saw this article, on this subject, and posted by you  genuflect genuflect extrahappy extrahappy extrahappy extrahappy extrahappy genuflect genuflect

(Kisses on a collection basis only, delivery costs will be too much.)

Mart.
