During the winter months, we draw off the grid between 2am and 5am to fully charge the battery, at around 13pence per Kwh. Then, at peak times, when the grid is under strain, we export back to the grid at 28pence per Kwh. When the clocks changed at the end of March, we started to rely on mainly solar energy to charge the battery to 100% and then export at the peak rate. In the summer, when there is an excess of wind and solar power, we have periods of free electricity, and in winter, special saving sessions when you are rewarded by turning everything off for an hour. This is just one small way electric companies are trying to manage the grid. However, this system will only work with a smart meter.

Exactly Dominic,

and by the way: the net-metering system is the best idea they had at the Gov. and the reason for many people is to install PV not for a "greener" Cyprus, but for excellent and safe return of their investment in a short time.

Nope it doesnt. under the net metering arrangement the export credit does reduce the fossil fuel at the time the surplus PV it is exported. But when it is inported it is laregly done from burning fossil fuels. Overall there is a reduction in fossil fuel being burned. But the cost per unit for consumers who do not have PV is at best the same.

example

lets say the whole of cyprus generates and consumes 1000 units over a year. all through fossil fuels.
lets say that fossil fuel cost 3 per unit. So the cost is 3,000 divided by the 1,000 units so everyone pays 3 per unit consumed.


lets say a new domestic PV produces 40 units, self consumes 20 units exports 20 units and imports 19 units over a year. so a net surplus of 1.

So for cyrus as a whole the number needed to be generated reduces by 40 to 960
fossil fuel cost 3 per unit. so toal cost 2,880. the EAC can bill for 960 a unit so everone except for the new domestic PV household pays 3 per unit consumed.

In fact the cost will be higher... transmission losses probably mean that for every 10 units expoted the EAC can use perhaps 9 of those units to others and the EAC has to generate say 11 to allow users to import 10 units. In addition the cost of electricty will also have an element of fixed cost for the generators etc.. these costs get included in the fuel cost and thus shared amongst the non PV consumers. so in the above example these costs would have been divided by 1,000 initially and then by 960.

Aren't there penalties to be paid to the EU (carbon tax or whatever it's called) for burning fossil fuel, which need to factor in as well?
