Re: Orthodox Easter Sunday - effect on electricty

lol.. yeah you are quite right a "small chance" obviously was a prediction that there would be blackouts... Incidentially, Greece was so concerned about the effect of easter on the electric supply system it ran a trial run (see https://energypress.eu/energy-authorities-content-with-easter-...

Orthodox Easter Sunday - effect on electricty

Orthodox Easter Sunday is a day when demand for electrity is low in Cyprus. Indeed the lowest daily demand for electricty in 2023 was on easter Sunday. On easter Sunday 2023 it is estimated that 59.8% of RES energy was curtailed. On easter Sunday 2024 that figure increased to 69% and significantly m...

Re: RES curtailments in Cyprus: A review of technical constraints and solutions

The study shows that expected curtailments will increase in future years and highlights ways which that expected increase may be mittigated. It does not identify any method by which there would be no need for curtailments. It is clear from this study that no matter how much battery capacity is insta...

Re: Good news for photo-voltaic electricity producer in CY

Batteries do make economic sense if there is a difference beween what they pay for electricty when it is being storred and the amount they receive for that stored energy is a big enough difference to pay for the capital and running cost of the battery. But if the energy they are storing is that gene...

Re: Good news for photo-voltaic electricity producer in CY

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? Yes There are carbon fines (or rather payments for carbon allowances). These are large (300 million plus a year) amounts of money But the installation of small ...

Re: Good news for photo-voltaic electricity producer in CY

under the old net metering arrangement the EAC used to make a profit as every year any surplus was cancelled in feb/march. Arguably it makes a profit at the moment as most domestic PV ysers run a surplus which grows every year. as soon as domestic PV users start reducing their accumulated surplus or...

Re: Good news for photo-voltaic electricity producer in CY

Well, it would reduce the need for the EAC to generate electricity from fossil fuels. That after all, is where the main cost is incurred, isn't it? 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 ...

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...

Re: EAC - Panels

No, the electricity stored in the batteries can be used instead of having to rely on fossil fuels to generate electricity. Isn't that the whole point? I agree that batteries (or rather energy storage) are a good thing. But I am focused here on the claim that electricty will cost less for ALL consum...

nope... it will reduce curtailments for domestic PV installations.. but overall increase prices for those without PV modules on their roofs

Re: Good news for photo-voltaic electricity producer in CY

Anyone figured out, how as per this article, buying expensive battery storage, to presumably mainly cut down curtailments for domestic PV producers, will reduce the price of electricty for everyone? I am all for battery storage but without dynamic pricing of electrity and getting rid of the net mete...

Re: EAC - Panels

Curtailment of domestic PV has nothing to do with smart meters. The EAC shuts down inverters by sending out a signal to a box that has a switch in it that either turns off or turns on the inverter. Newer installations (from sometime in 2024) have the box... most older installations do not. If you ha...

Re: Good news for photo-voltaic electricity producer in CY

Our home in the UK has battery storage, plus PV panels. 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 chang...

Re: Using solar energy during periods of curtailment

it doesn't mean all your panels stop working entirely. It’s more like they’re allowed to produce only a certain amount, so you might still use some of that energy right away for things like cooking or ironing. However, most of your energy might be redirected to the grid. It really depends on your s...

Re: Using solar energy during periods of curtailment

A question for the experts: Even during a period of curtailment (when the EAC shuts down your solar harvesting for net metering), are you still able to use the energy your panels are producing during that time? In other words, is this a good time to use appliances, cook, iron, etc, because you can ...

Re: Bill to prevent solar panel shutdowns ‘accepted in principle’ by state agencies

The interconnector is a massive waste of time and money. If it works we will import electricity from the rest of Europe be charged more than Europe (to recoup the cost of building the cable etc) and not have any generation ability on the island. The alternative is that we end up paying for a white e...

Re: Bill to prevent solar panel shutdowns ‘accepted in principle’ by state agencies

This is nuts.. never going to work.

The problem is a financial one.

Just give domestic consumers with an inveter cut off switch installed a new smart meter. Then whenver their inveter is cut off, give them free electricty and 4 units credit for every hour their inveter is cut off.
