Under this partially load shedding agreement, consumers will agree to partially reduce their electricity consumption during peak hours in return for an incentive payment for each KWH reduced. The MNI believes this arrangement could be suitable for many consumers, including large a/c consumers in public buildings and governmental institutions and hope to be able to operate the system by the summer of 2009
Generation units that can react very quickly to meet the needs of the electricity grid
Special tariff offered to consumers who are willing to sign up to a peak shifting / rolling peak scheme, according to which they agree to be cut off from electricity grid during those hours when not enough electricity generation is available – namely during peak hours – in return for a lower electricity tariff during the rest of the year. In Israel the incentive is a 10-15% reduction on the electricity tariff during the remainder of the consumption hours
During peak electricity consumption utilities need to operate more expensive power stations that use more expensive fuels than those used for base load and thus the electricity tariff increases. Peak shaving schemes enables the consumer to cut down his consumption from the grid during these peak times
Coal power station belonging to IEC situated in Hadera and situated on 1,200 dunam of land. One of the country’s two largest coal power stations with an installed capacity of 2,590 MW, which was constructed at a cost of $3 billion and which represents 25% of Israel’s installed generation capacity and is composed of two large coal stations. The plant however provides up to 35% of the country’s electricity needs due to the relative cheap cost of operating this coal power station. The station was graded as the most polluting station in the country and in fact is responsible for 42% of the country’s emissions of sulfur dioxide and nitrogen dioxide.
1st August 2011 – MNI Minister Landau ordered that 4 of the 6 turbines be converted to natural gas with coal as back up
Calculations can be made for a power plant to optimize the number of generating units in operation for each hour of the day in order to attain the total generation scheduling of a plant in the most economic way, including tradeoffs that need to be made between start-up/shut-down of generating units and the plants overall efficiency. optimization. Optimal dispatch needs to be carried out on a country-wide scale especially in deregulated electricity markets, to include energy security, price issues, emission levels, etc.
This is the total possible capacity that can be produced from the operational production units in the system and from the available operational units in the reserve, within 30 minutes. As per the Optimal Dispatch operational policy, it is customary to maintain 600 MW.
