11.2% of capacity in 2020 will be intermittent wind and solar power and this will have a low capability element and an even lower capability credit. This implies that it can not replace base load nonrenewable fuel source or nuclear capacity on a one for one basis in terms of megawatts and a bigger amount of sustainable capacity will have to be developed while at the exact same time maintaining traditional powered plants for back up. This has a number of results.
Capacity credits are lower than load factors due to the fact that they take account of loss of load likelihood (LOLP), which is the unforeseeable variability that can be so challenging to manage for stabilizing the system. Capability credits are the quantity of traditional capacity which can be taken out of the system while still maintaining its security. We forecast around 799 GW of wind and solar capability by 2020 and with a capability credit of 15% this would mean it can substitute for 120 GW of fossil fuel or nuclear power.
Considered that the future capability mix is still planned to supply the exact same amount of electrical energy this will result in a lower total utilisation factor for plant. Utilisation wavered around 4.1 to 4.2 through the 1990s and up to about 2007, when it started to decrease, falling from 4.2 in 2007 to 4.1 in 2008. It will continue to decline, reaching 3.7 by 2018.

Capability credits are lower than load aspects due to the fact that they take account of loss of load likelihood (LOLP), which is the unpredictable irregularity that can be so tough to handle for stabilizing the system. Capability credits are the quantity of standard capability which can be taken out of the system while still preserving its security. We forecast around 799 GW of wind and solar capability by 2020 and with a capability credit of 15% this would suggest it can replace for 120 GW of fossil fuel or nuclear power.
