There are normally few customers between 1 am and 7am and you just keep 1 or 2 staff on. Now all 6 of the new ones occasionally arrive at various times during these hours. Some stay 2 hours and some 6 hours with no schedule. You still have to employ your original 2, there is not enough customers. You send one permanent staff and 5 news ones upstairs to watch TV. You ask the shop next door to employ some of the new ones, but they will only pay 20% of your wage bill. Sometimes the shop next door will only employ them if you pay them. A tax is put on you permanent staff to give a bonus to the new ones.Val Martinhttps://www.blogger.com/profile/03248166816744009791noreply@blogger.comtag:blogger.com,1999:blog-6298568350190982130.post-37945494031624315972015-01-01T23:52:42.065+00:002015-01-01T23:52:42.065+00:00Imagine you are running a supermarket in Mullingar...Imagine you are running a supermarket in Mullingar. You employ 14 full time staff, 10 of which can cover the checkouts. You also employ 6 part timers for busy days and to replace absent staff . 2 of these can cover the checkouts, and you are competing with 2 other outlets locally. Margins are tight and staff are good. <br />You receive a binding order from the Department of Labour that you must employ 6 people from the live register and pay them 25% more than permanent staff. These new ones will work only 25% of the hours of the permanent staff ,but can come and go as they wish, Monday morning, 12 mid night, 4 am whatever they want. They can leave work when they like, provided they work a quarter of the permanent staff's hours. You must give them work and if there is no place for 1,2,3,4,5 or 6 of them, you must pay them a slightly reduced rate and put them watching TV upstairs. You cannot schedule them for busy periods and you cannot give permanent staff a day off to be replaced by them. 1 or more may come in or may not. In fact all 6 might arrive in at 3 am when the shop is closed, so you have to employ a security man to mind the doors. and heat the TV room.You also have to employ an extra manager to manage the new staff arrangements. If 4 arrive in at 11am Wednesday, you must send 4 permanent staff upstairs to watch TV, but you cannot allow any to leave because the new ones often walk out after 20 minutes to make the hairdressers etc. Permanent staff complain that they are suffering fatigue from running up and down the stairs to replace new ones and find the new ones damages their routine. You receive word that the state is claiming the plan is reducing unemployment and the public seem to approve of it, but complain that it is cheaper to shop down the road or in the North where groceries are cheaper. You are finding that new staff are causing a lot of breakages and giving wrong change leading to refunds and customer dissatisfaction. All new ones work the till, but you feel only 3 are competent to do so. All most be treated equally, and you discover you must maintain 45% original staff or problems happen. You also discover that if you allow more than 50% of the staff at any one time to be new ones, all hell breaks loose because the new ones don't have the skills to run the shop by themselves. A fixed payment must be paid to all staff just to exist and the new ones get this too (capacity payments) That's one way to explain wind energy, which cannot be scheduled and must be paid for any way. This is a normal opening hours scenario.Val Martinhttps://www.blogger.com/profile/03248166816744009791noreply@blogger.comtag:blogger.com,1999:blog-6298568350190982130.post-1949926590780259122015-01-01T11:45:49.466+00:002015-01-01T11:45:49.466+00:00Another excellent blog. Increasing CER-permitted ...Another excellent blog. Increasing CER-permitted ROCOF is an inherently destabilising policy and mutually exclusive with high efficiency energy-balanced combined cycle generating plant. The faster that asynchronous generation can influence grid characteristics due to higher SNSP, the faster the reaction of spinning reserve has to ramp up or ramp down to counteract it. <br />The wind farm operator should be responsible for maintaining supply at the connection point within specified stability criteria using technologies such as short-term blade-feathering and dynamic energy storage at the operator's expense. In other words, put the onus on the operator to make the wind farm present to the grid as a stable generator, rather than destabilising the grid with undisciplined supply.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6298568350190982130.post-46771535837795524082014-12-30T11:03:23.176+00:002014-12-30T11:03:23.176+00:00Just to clarify, the payments referred to in this ...Just to clarify, the payments referred to in this blog would include power produced as well as power not produced. The key point is that when a generator acts differently to its schedule, it usually costs money. Otherwise, it doesnt become profitable for the plant and they go out of business. <br /><br />The plan to generate large amounts of electricity from variable wind with priority dispatch will result in significant levels of constraint to conventional plant. The constraint costs for 2014 were roughly equal to the alleged SEAI fossil fuel savings for 2012.Irish Energy https://www.blogger.com/profile/16354100971015557625noreply@blogger.comtag:blogger.com,1999:blog-6298568350190982130.post-23997328912651700572014-12-29T22:24:35.457+00:002014-12-29T22:24:35.457+00:00Amazing the amounts of money paid to generators no...Amazing the amounts of money paid to generators not to produce power. <br />Currently the CER is changing the grid code to increase the RoCoF (Rate of Change of Frequency) to allow more wind or SNSP onto the grid from the current level of 50% to a theoretical 75%. This will have a number of adverse impacts including increasing the ramping of the conventional plant, leading to increased wear and tear. <br />It will also increase the constraint payments paid to conventional plant.Anonymousnoreply@blogger.com
