This is a bit of a topic. I will be intrigued to see if it gets any interest.
For the last 20 years or so we have had a simple system of getting new renewable generation onto the electricity network. It has been offered some sort of state support. This means that the extra funding per kWh it has needed in the past is made up by some sort of extra payment either directly by government or more recently (more than the last 10 years) by a government determined system that puts the extra onto our electricity bills. The extra being the difference between the whoelsale price and the price the renewables need to work. This latest approach has now been stopped and various discussions are going on about what to if anything to do next.
What is interesting though is that recent large scale solar tenders in the middle east have got the price of solar electricity for a large scale a long term contract down to around 2p / kWh. Further a recent deal in Australia saw wind power down to around 5p/kWh. These cases are both for very large scale projects (on a peak basis roughly 4,000 to 12,000 houses worth) with long term contracts (20 years). So my question is really what exactly by way of support do we still need if any and how can compnanies like Bulb who buy renewables but probably from the pool of supported projects support new projects at the scale that is realisitic for a company of this size but at a price that is attractive enough to keep us all as customers? Further how do we match the huge variablity in demand (thats us) with the seasonal and daily variability of the generation (thats the sun wind and rain)? I guess that is three questions but I hope that encapsulates the main points.
Does anyone have any ideas?
