Well chaps,

it's been a long time in the planning but at last our island is heading towards its long awaited goal of drawing some power from the abundant rain we are blessed with here on the West Coast. https://www.raasayrenewables.co.uk/index.html#readmore Pleased to say my son is actively involved and on the board as well as other young blood from the island. Young Camillitech has had plenty of hands on experience with his Dad right enough.



Cheers, Paul

Had a look at the website.
Under CO2 emissions, they saved "127 cubic tonnes". Over the last year. Not heard this combination of units before.

Hi Paul, it must feel really good that your investment in the young one has not been wasted.

Good luck with the fund raising/share issue.

Ha ha! I didnít notice that one, but I did note they were only predicting running at an average of 50% of installed capacity - and wondered why. 

Also, £958k (already £307,700 + the additional £650,000) seems quite a lot for an installed capacity of only 137kW (or the actual predicted average output of ~60kW (520MWh/annum).

Good to see! Well done. Smiley
I'd invest at 4.5% pa variable on BOE rate with a cap or 4% fixed and 1st return in 2022, can't as is now. Nonetheless I wish you best of fortune and much clean power!

Reading the prospectus, there is a 50kW grid limitation on Skye for the next 3 years - so output is limited to island consumption + 50kW, and they mention there is spare capacity to use on the island as a result. If the grid gets reinforced, they can generate rather more.

Aye PDF,

once the grid is upgraded, things will improve and there is talk of using some capacity locally via the distillery during the day for heating the stills and the ferry overnight for charging the batteries. Hallaig uses around 750kWh per night, be really useful if we could charge her up from 'locally grown' electricity  Wink

Hallaig, the ferry, cant be easy to charge 750kwh from a 50kw supply overnight. How long is night up there. Huh

But I will be a great help Ken.   
  The Ferry will ensure that there is always some place to put the surplus. It is a brave venture.

Biff,

Regardless of the source of the leccy charging 750kwh from a 50kw supply is 15hrs not counting losses and battery charging tailoring off with SOC. I guess multi chargers but then only one mains cable covering all the chargers. A bit of a load. Just wondering.  Ah, perhaps the 50kw is per phase but still.

Ken

But why limited to 50KW?  The Hydro is lmited to 137KW and therefore the charge could be 137+50 = 187KW (Ok assumes no one on the island uses any other electric),  so only needs about 4hrs  Grin
