Ports: electricity for ships in ports

45.001 This chapter considers the European Union (“EU”) legal regime which requires ships to use shore-based electricity, where possible, rather than using their own engines. The requirement to use shore-power (rather than ship-power) is motivated by the fact that ship-power usually leads to more emissions than shore-power and so shore-power is more environmentally friendly. This chapter should be read in conjunction with the other chapters in the book, including, in particular, those dealing with the marine environment.
