On 7 September 2024, Equinor and its partners began partial power-from-shore operations to the Troll B and Troll C platforms under the Troll West electrification (TWEL) project. Electricity is supplied from the Kollsnes facility northwest of Bergen through a 132 kV subsea cable via a new electro building shared with the Oseberg field, first to Troll B and then on to Troll C, where new modules adjust the voltage to onboard systems. Following this initial energisation, processing and other energy‑intensive systems on both platforms are powered by electricity from shore, while large export compressors remain gas‑driven, cutting CO2 emissions by about 250,000 tonnes and NOx by around 850 tonnes per year.
