Nautilus 150MW Project

SBS signed an exclusive site development agreement with State-owned electrical utility, PT. Perusahaan Listrik Negara (PLN) in 2015, (extended in 2017) to develop utility-scale, tidal turbine generator arrays around the Indonesian archipelago. The first project is designed to progressively deliver 150MW from tidal-stream resources in the Lombok Strait. As part of Indonesia’s De-Dieselisation Plan, the project will progressively build-out in a phased manner that will see deployment of an initial 10MW array during Phase I. by Dec’ 2024, expanding through 70MW then to 150MW by 2026.
The development contract includes the FEED activity and EIA scopes of work; design of the TTG site layout, based upon our known topography of the offshore site; export power cable route; turbine manufacturing; installation & commissioning. Secondary survey data gathered and analysed during the FEED activity will ensure TTG drive-train configuration exactly matches the unique characteristics of local tidal resources in the Lombok Strait.
The initial 5 x 2MW TTGs will be supplied from the UK while we build the local supply chain in Indonesia. Agreement between SBS and State-Owned fabricator, PT. PAL (Persero) in Surabaya, will see local manufacture of the turbine support structures from 2023, and manufacture of the tidal turbines by 2024.
