OK. I know this is a bit of how long is a piece of string question but am throwing it out there.

How much electricity do you use when the boat is unattended? According to my last bill I used 745kw in 14 days. All I have running are battery charger, 2 fridges, 1 freezer, immersion heater and kettle for the occasional cup of tea?

Does this sound excessive?

My electric bill is around €600 per month @ a rate of .34 per kw.

What is the price per kw in other marinas?
 
Crikey.

In Ireland it is illegal to re-sell electricity at profit, so think our fee is about 18c (euro)/unit

Do you live on the boat? If not, I think it's a waste having the fridge/freezer running.

I clock up about €300 per winter running a de-humidifier / 450w heater / battery charger

Crickey! Where are you based?
(Just so I know not to visit!!)
 
My invoice came through for the period April through to September totalling £15. We don't keep the power connected when not on the boat though but more from the perspective of not being comfortable having a route through to earth through the electrical connection more than containing costs. We'll do the same in winter running a line in to the boat to power heaters and a dehumidifier rather than leaving the shorepower connected.
 
goodness ! 7 kWHr per day ! That's more than a house and a family with an immersion heater.

Living on board a 16 tonne boat during the winter in a London marina, I clocked up about £4 a week.

I don't skimp, battery charger, 2x600w heaters, fridge etc, but I'm nowhere near your spend.
 
We only use 5,000 KWh a year for our house. So that would be 192 KWh for 14 days. You must live on board!

On our boat we used 40KWh for the three months from July to September.

You really must do more to care for the environment!
 
My use is similar to Gary's. I spend circa £50 a year on elctricity, 90% in the Winter when powering the tube heaters. I charge the batteries every few weeks, and use the immersion very occasionally.
 
I don't live on board, BTW I am just the skipper so whilst concerned about the cost it doesn't directly affect me.

Boat is a Princess 85 motor yacht. Based on Costa del Sol.

Alas cannot turn stuff off as owner could turn up at anytime and warm champagne and wine doesn't go down to we'll. even more so would be a cold shower!!

Interesting in Ireland you cannot sell electric on at a profit. Here in Spain they do as they please.

That's equivalent to drawing 10 amps 24/7, which does sound excessive. The immersion and kettle suck quite a lot of juice when they're on, but it sounds like they don't get much use. The fridges and freezer draw very little, which just leaves the battery charger. IIRC you have quite a large boat, so I guess if all the lights are on then the charger will draw quite a current to keep the batteries charged, but I suppose this would only be for a few hours a day max, and probably you don't have all the lights on.

You'll have an ammeter somewhere on the panel, i'd monitor this and see what you're typically drawing.

That's interesting.
In our area of Spain, the electricity charge is included in the service charge and spread amongst all berths on a sq metre basis.
So, us with bigger boats tend to get a better deal.
My service charge is just over £2000 p.a. inc all the electricity/water I can use.

I thought this was the norm in Spain

I suspect that in Spain it's a bit of a free for all?? Here in Ireland we have a Commissioner for Energy Regulation.

We were being charged over-the-odds for the electricity itself, so a bit of investigation later and all is sorted.

However, marinas are free to charge a service charge ie. for the installation of the facility. They just can't profit on the actual electricity that passes through the service

My elec rate is also .34/kwh and I use around 600kwh when the boat is not in use for a full month, so 200 euros ish. Similar to you, I have the 3 batt chargers, fridge/freezer on permanently and the occasional kettle/lights in use. Are you sure you dont have other stuff running?
 
Hi MYAG

I am on boa most days of the week even when owners isn't likely to be on board so there will be lights and the odd bit of aircon / heating.

I have stuff like the alarm system on but this will be neglible, wireless router which once again won't take much consumption. We will however have 6 televisions in standby mode, two KVH satellite systems in standby mode and small phone system.

I guess if you shut these down then this can be my difference!

Just checked my amp meters and I am consuming 8 amps just sitting with the above items on.. I also only run 1 battery charger although having two on doesn't change consumption.

I guess it is what it is
 
Our bill for July through Sept totals £113.36. I don't know what that is KW wise as it doesn't state it but we have 2 fridges running 24/7 and all the usual when we're down there. During the winter we will have the dehumidifier running and the tube heaters so it will obviously increase over that period. It says it's 9.5p per unit.

I bet the aircon for an eighty five footer uses more juice than many small African countries!

I've never delved into the intricacies of my marina lekky bill but it's never been more than £150pa. Having said that, I'm now on a meter so it could change.

We're not allowed to mark-up electric prices in England either.

Same in the UK. The law is mostly aimed at landlords where a single electricity company supply is then divided among several bedsits with meters run by the landlord not the company. But I believe it applies to marinas as well.

My power use at the home berth is zero, as there is no electricity on the pontoons :)

Your last bill will have covered September I guess, when it was still quite hot. How much did you run the aircon? Nothing else you've mentioned comes close to explaining the 745kw in 2 weeks, but air-con running several hours a day may explain it. TV's and comms gear on standby uses next to nothing.
