I am looking for an example feed-in-tariff which is released by any goverment to encourage users for battery installation to consume self-generated electricity in smart homes.
This could be relevant to your question: http://www.renewableenergyworld.com/articles/2012/04/german-energy-policy-reconciling-energy-storage-and-feed-in-tariffs-with-self-consumption-tariffs.html
Looks like there are some incentives for self-consumption in Germany.
Yes, this is my problem. I am trying to increase renewable energy usage in the neighborhood area by local PV generation and I aim to use realistic price values for electricity tariff. However, FIT is defined higher than the normal consumption price, thus selling electricity back to main grid make more sense rather than using at further hours. Therefore, there is no need to use battery in houses for self-consumption. I guess this is not officially considered yet for real cases!!!
This maybe a little late but the UK have two Feed-in Tariff (FiT) payments. The generation tariff which is what you get paid for each kWh you generate and also the export tariff which you get paid if you export to the grid.The logic behind the export tariff is to incentivise you to make your house more energy efficient and not waste energy.
The amount you get for exporting to the grid is less than what you would have to pay to buy it back in the UK.Roughly 4.5p for export as opposed to 8-20p depending on tariffs to buy it back. The generation tariff has been decreasing since it was implemented at about 50p/kWh down to around 12.5p/kWh at present with future rates of about 4,9p to come in february 2016.
So on the face of it there is an incentive to store energy for later, but there are other factors to consider e.g. the initial cost, efficiency and lifespan of the energy storage system.
The other problem is that a large part of the demand in the UK would be seasonal storage; solar provides more kWh in the summer than it does in the winter. Storing this energy is a lot more difficult than storing from day to night.
With time of use tariffs likely to coincide with the smart meter role out by 2020 the incentive to store energy is likely to grow on the consumer side. The grid already has an incenitve in load smoothing, with increased renewables decreasing flexibility in the time that energy can be generated.
(Although all my interests on here are to do with remote sensing/geology/Mars I currently write blogs for http://www.yougen.co.uk/blog/ could be of interest to you as we have been looking at energy storage and feed-in tariffs a lot recently.) If you would be interested in writing a blog on the subject yourself, feel free to message!
