SP Energy HubAnnual ReportReliabilitySustainabilityInnovation Powering Sembcorp Marine's Tuas Boulevard Yard with Solar and Green Energy Tech SUSTAINABILITY Photo: Sembcorp Marine SP Group (SP) inked an agreement with Sembcorp Marine to expand its Tuas Boulevard Shipyard (TBY) rooftop solar capacity to 8.5 MWp (Megawatt-peak). In this agreement, SP will deploy 4.0 MWp of solar energy across seven rooftops at the yard. The generation, usage, and storage of solar energy will be managed and optimised by our Green Energy Tech (GETTM) smart energy management system that incorporates Internet of Things (IoT), Artificial Intelligence (A.I.), sensors and advanced metering infrastructure to realise significant energy savings. President & CEO of Sembcorp Marine, Mr Wong Weng Sun (L) with the Group CEO of SP Group, Mr Stanley Huang at the signing ceremony of the new agreement. This new agreement is an extension of both companies’ successful partnership from 2017 where both companies partnered to develop and implement a digital energy solution, with the installation of an initial 4.5 MWp of rooftop solar panels at TBY’s steel fabrication facility. Collectively, this will provide close to 60% of electricity consumed at the yard’s steel fabrication facility, equivalent to powering more than 2,300 four-room flats for a year. It also reduces annual carbon emissions by more than 4,200 tonnes, equivalent to taking approximately 1,300 cars off the road.

Menteri Pembangunan Negara, Encik Lawrence Wong, merasmikan operasi loji sistem Singapore District Cooling (SDC) – sebuah anak syarikat di bawah Singapore Power (SP) – yang baru selesai projek pengembangannya semalam. Pendinginan daerah melibatkan proses penghasilan air sejuk yang disalurkan kepada bangunan di daerah itu, yang antara lain bagi sistem hawa dingin di bangunan-bangunan di situ. Selain berupaya menjimatkan tenaga, sistem bawah tanah dengan rangkaian paip sepanjang lima kilometer itu juga boleh membantu bangunan di kawasan tersebut mengatasi cabaran ruang mereka dan menjimatkan kos kerana kini mereka tidak perlu memasang alat pendingin atau menara pendingin di bumbung bangunan sendiri. Ketua Pegawai Eksekutif (CEO) Penguasa Pembangunan Semula Bandar (URA), Encik Ng Lang, menyifatkan usaha membangunkan rangkaian pendinginan daerah bagi kawasan Marina Bay itu sebagai idea berani yang memakan masa bertahun-tahun untuk menjadi kenyataan. Sebagai contoh, projek itu melibatkan kawasan lantai kasar (GFA) kira-kira 1.25 juta meter persegi di Marina Bay yang ditetapkan sebagai zon rintis bagi projek Sistem Pendinginan Daerah itu. Pemaju di One Raffles Quay dan Marina Bay Sands membina ruang bagi loji pendinginan daerah itu sebagai sebahagian syarat tender tanah pemerintah. Hasilnya, dua loji – satu di besmen One Raffles Quay dan satu lagi di besmen Bayfront Avenue di Marina Bay Sands – disepadukan sementara loji yang ketiga terletak di One Marina Boulevard. “Hari ini kita meraih manfaatnya hasil perancangan awal dan reka bentuk yang difikirkan dengan teliti, serta usaha mencipta lebih ruang dan menjimat kos bagi mengurangkan pengeluaran karbon,” kata Encik Ng. Dalam pada itu, SDC turut mengumumkan semalam bahawa Marina One di Marina South telah menandatangani perjanjian dengan pihaknya. Ini bermakna SDC kini menawarkan khidmat kepada 12 pelanggan secara keseluruhan.

This resulted in natural gas prices also falling by 4.5%, as the price of natural gas in Asia is pegged to fuel oil price. 2.
