Perenco Trinidad & Tobago has completed a significant electrification upgrade across the Teak, Samaan and Poui (TSP) offshore fields, advancing efforts to extend the productive life of one of the country’s longest-producing offshore assets.
The latest phase of work focused on modernising the Teak field through the installation of a high-voltage electrical network linking the Macarius power hub to the Teak Echo platform and associated satellite installations. The project included approximately 28 kilometres of subsea cable installation along with upgraded electrical infrastructure across the asset.
According to the company, the improvements strengthen safety, reliability and energy autonomy across the TSP fields while supporting long-term operational efficiency.
Perenco has operated the TSP fields since December 2016, when it acquired a 70% working interest and operatorship from Repsol. The remaining interest is held by state entities, including Heritage Petroleum Company Limited and the National Gas Company of Trinidad and Tobago. Perenco is now the 2nd largest hydrocarbon producer in T&T (on a barrel of oil equivalence basis) after the acquisition of Woodside’s T&T assets and bpTT’s Cashima, Amherstia, Flamboyant and Immortelle (CAFI) assets.
The TSP fields have been producing for several decades and form part of Trinidad and Tobago’s mature offshore oil portfolio. As national hydrocarbon output faces decline, operators have engaged in brownfield optimisation to sustain production from existing assets. Data from the Ministry of Energy and Energy Industries show that crude oil production has trended downward over the past decade, reinforcing the importance of efficiency improvements and infrastructure upgrades in stabilising domestic supply.
Electrification is an element of this optimisation strategy. By consolidating power supply through a high-voltage network, operators can reduce reliance on individual platform generation systems, improve operational reliability and lower long-term maintenance costs.
For mature offshore fields such as TSP, targeted investments in infrastructure can enhance uptime, reduce operational risk and extend field life in addition to pursuing greenfield projects.
Energy remains central to Trinidad and Tobago’s economy, contributing significantly to export earnings, government revenue and foreign exchange inflows. Incremental production preservation from mature offshore fields therefore carries national importance.
The completion of the TSP electrification programme demonstrates how infrastructure modernisation and brownfield investment are increasingly shaping the evolution of Trinidad and Tobago’s offshore sector. As upstream operators navigate natural decline rates and shifting capital priorities, such projects are likely to remain a defining feature of the industry landscape.
