46,000 litres per annum for 75kWe Generator???

[JonnyVine]

46,000 litres of gas oil amounts to £32,000!? Wow

Make sure heating, cooking and refrigeration are on bulk lpg tank. 75kw is alot of power even for a pub. Because people have to run a generator anyway they go mad for resistive heating and before you know it theres a power station in the garden.

 

 

Bulk LPG is very expensive.!

If cookers are on LPG and they have woodburners for heat, then what do they need all that power for? Fridges and freezers are efficient, as are modern lightbulbs.

Unless they are running a 24/7 rave that involves having a 20kw sound system?

I thought lpg was able to compete with kero. Generators only turn about half the energy into electric the rest goes out through the rad and exhaust. Perhaps a generator chp unit.

there are some grants i think if you off the grid for hydro etc and a lot of places are putting in small hydro for this reasion

surprised you didn't suggest wood/chip burner:001_smile:

 

I did for heat but wood fired CHP isn't fully developed yet - fact.

[JonnyVine]

I was told that if you install hydro then you haveto pay a levvy to the water board?

I would have thought this was the ideal "loading" for CHP unit, fired off bulk gas or 28sec oil. Should be able to do a fact based hard-nosed financial calc vis-a-vis pay back period.

As I imagine peak heat load would reasonably concide with peak electrical load in the colder darker winter months.

Might need to take a hard look at elect demands as well such as old inefficient light fittings.

Incorporate a wheen of solar panels and a feel-good windmill to blag the green grants.

You could have a reliable German 45 kwe CHP system but it is not cheap at 176,000 euro's. The main downside with the system is the need for 15% MC woodchip. Not a problem for me but finding 15% MC on Dartmoor could be a problem as the UK is not geared up for quality low MC woodchip unlike Germany.

I can install a 3.0MW wind turbine for you, retail is roughly £2Million but you would need to sort out your own infrastructure!
