Bydd safleoedd yn cael eu mapio i roi asesiad lefel uchel o ble mae'r potensial gorau, gydag astudiaethau dichonoldeb manylach yn cael eu cynnal ar y rhai yr ystyrir bod ganddynt y tebygolrwydd mwyaf realistig o gysylltu ag adeiladau presennol a datblygiadau newydd.
Sites will be mapped to give a high-level assessment of where the best potential lies, with more detailed feasibility studies carried out on those considered to have the most realistic likelihood to connect to existing buildings and new developments.
