Trev’s Brisbane Forecast for next 7 Days from 1 September (click here for podcast)
Over the past couple of weeks I mentioned the first solar PV system (Solar One) at Coolum and my own system as the first REGISTERED solar power station in Queensland. When the Federal Government legislated to allow solar systems to be connected to the National Electrical Market, to feed power into our homes and to sell excess energy to the electricity network, it required that we register our systems. This was administered via the Australian Government’s Clean Energy Regulator. My system was given the code SRPVQL01. This required us to report annually on the electricity generation in megawatt-hours, round numerically down to a whole number. This was then assigned a value according to government rules of about $40 per MWh*, and called a Renewable Energy Certificate (REC), later changed to Large-scale Technology Certificate (LTC) for registered power stations. I could then sell these certificates at some stage to polluting generators such as coal fired power stations who were required to off-set some of their greenhouse gas emissions. This was part of an emissions trading scheme, based on the polluter pays principle.
My system would typically generate about 1.9MWh annually, i.e. less than 2 MWh. So, I would only be credited with 1 LTC, not 1.9 LTCs. I protested that I was not receiving full credit for my clean energy generation. But it fell on deaf ears. The system was designed essentially for very large generators of many megawatts output, not a few kilowatts output. Eventually small generators such as my system no longer had to register as a power station. If they did, there would now be 2.7 million small generators on the National Electricity Market.
This week the days are warming up with light to moderate winds from the east till Sunday. Then a southerly wind changes should cool things down, after a trough and front passes across the continent again. The easterly winds will bring maximums of around 24 to 25 degrees Celsius and minimums of 14 to 16 C. But that will cool down next Monday and Tuesday to around 11 to 23 C. There’s a moderate chance of a storm on Saturday, or at the very least a shower or two.
See ya next week.

*A megawatt hour (Mwh) is equal to 1,000 Kilowatt hours (Kwh). It is equal to 1,000 kilowatts of electricity produced or used continuously for one hour.
