Generation presents information on all the sources of generation which are used to meet the ACS Peak GB Demand as defined in the Glossary and presented in Electricity Demand. Accordingly, Chapter 3 presents information on Large power stations (directly connected or embedded), Medium and Small power stations which are directly connected to the GB transmission system and directly connected External Interconnections with External Systems.
Embedded generation may be Large but is more likely to be either Medium or Small. Large embedded power stations are reported in Chapter 3 as explained above. Medium and Small embedded power stations and embedded External Interconnections with External Systems are reported in this chapter.
Much of the existing and future embedded generation is either in the form of combined heat and power (CHP) projects or in the form of renewable projects. This chapter considers these two types of generation source and, in so doing, also reports on non-embedded renewable sources of generation (e.g. Wind farms).
