Emergency generator appeal

Storm Arwen has taken out power and phones to the rescue. We have been told it could be weeks before the pylons are replaced to bring power to the rescue.
We have kept everything going for 2 days and have a small temporary generator taking the edge off that works for 4 hours then runs out of fuel, so we need a big generator to ensure we can keep all the animals watered and warm in the future, linking in the future to renewable energy and a battery house.
The urgent need of a generator installed will be around £15,000 all in for the cost of purchase, installation and integration with all barns and outbuildings. Any help you can give towards this would be most appreciated.
We will have to get a crane in to drop the generator into position.
Once this is done, it will integrate with renewable energy plans we want to bring to the rescue next year.
Not a single animal was lost in this storm but we need to make sure we are more resilient for future storms.
Thank you so much.
