ABOUT THE WEBINAR
Subsea HVDC interconnectors have gradually increased in power capacity and length over the last 50 years, playing an increasingly strategic role in national and transnational grid connections. These power links have enhanced countries’ energy security, fostered international collaboration in the power sector, and, more recently, eased the integration of intermittent renewable energy sources. The Gotland HVDC link, built in 1954, was the first HVDC subsea cable, 50 km in length, connecting Gotland Island to mainland Sweden and operating at 100 kV with a 20 MW power capacity. Today, subsea HVDC cable is a mature technology with approximately 10,000 km of cables currently in service, predominantly deployed in Europe (more than 70%) where most of the manufacturing facilities are located. Latest developments enable fabrication of subsea power cables rated to 600 kV and delivering capacity up to 1200 MW.
PLN had planned to install HVDC Undersea Cable, it was supposed to interconecting Sumatera Grid and Jawa Bali Grid. Even though this plan has been postponed, however many lessons during preparation and early development is valuable to be learned. Mr. Didik Sudarmadi will share his valuable insight in preparing HVDC Undersea Cable in Indonesia context. As an archipelago country, with big potential renewable energy resources often far from the central load, it is important for Indonesia to embrace the technology of HVDC Undersea Cable. Dr. Nanang Haryanto will share his deep understanding on this subject matter, referring what has been done in other countries. Amongst the eleven Southeast Asian (SEA) countries, the combined annual electricity consumption of Indonesia, Malaysia and Singapore represents about 50% of SEA power consumption. Yet, Power generation in Southeast Asia is dominated by fossil fuels, while most countries are committed to engage transition energy to cleaner and renewable energy. The potential for a long HVDC subsea interconnector is one of the few credible options to lower emission levels of Indonesia and its surrounding countries, while being highly suitable for integration between islands into the centralised nature of the country’s power system and strengthening energy security. Moreover, the subsea cable technology creates favourable conditions for the development of long-term capital-intensive HVDC projects. Mr David Griffin will share how Sun Cable will utilize HVDC Undersea Cable to bring huge amount of Renewable Energy to Singapore.
