Chris;
In the US, separate metering is often used. I typically leave our boat unpowered, as we have 240w of solar, plenty to keep things charged up. We do pay for the juice we use form the grid, billed monthly.
On our house, we have 2kw of solar panels, and two electric meters. One in, one out. It could be cone with one meter, but the power companies are not smart enough for that ;> We sell all we generate, as we get a better rate than the cost of electricity off of the grid, as it is “Green”.
There is no reason that this could not be applied to marinas!

Hi Mike,
I've had thoughts along similar lines, but not quite the same...
Around the marina's I've been on I notice the same thing - hundreds of boats not being used. No only are they not being used but the majority are plugged into the grid while at the same time bristling with solar panels and wind generators doing nothing.
Chances are there's enough generating capacity in all those unused solar cells and wind generators to power the whole marina - if only the power could flow in reverse and back into the grid. The technology is already used for house solar - I'm sure it could be easily adapted for marina use.
A small first step would be for marinas to bill separately for power usage rather than including that service as part of berthing charges. Then there would be some economic incentive for boaters to at least rely on their own on-board power.
When you combine this generating capacity together with the storage capacity you refer to, it could be an even more useful resource.
Cheers
Chris

Well maybe not gold but, possibly some silver for those of us who own electric boats. Last week I was on an Amtrak train heading to Washington D.C. speeding along at 90 miles per hour (propelled by an electric motor BTW) reading an article about V2G (Vehicle to grid) technology. If it works for cars why not electric boats that are sitting tied to the dock with no one on them during the week.
