CASAREM Project: TUTAP Rationale: Connect Central Asian countries to planned Afghanistan grid who in turn can re-export to Pakistan ADB financed Afghanistan Power Sector Master Plan* identified the need for a unified Afghanistan grid with asynchronous connection to neighboring central Asian countries. TUTAP uses existing and planned assets in Afghanistan to connect Central Asia to Pakistan TUTAP is an acronym of countries to be directly connected to Afghanistan grid, being Turkmenistan, Uzbekistan, Tajikistan, Afghanistan and Pakistan *

Impact of AFG power system developments Today
2032
• Multi island system
• Integrated transmission network
• Peak load 850MW
• Peak load 3500 MW • Annual energy consumption 18400 GWh
• Annual consumption 3800GWh
• Power exchange options with neighboring systems
• 70% of the energy covered by imports

Proposed Asynchronous Operation • UZB, TAJ and TKM systems are not operated in synchronism. • Asynchronous interconnection via HVDC Back to Back at Pul-e-Khumri (PUK). • Future connection to Pakistan again with HVDC BtoB. Benefits of HVDC back to back Modular technology- built in stages to meet evolving needs Facilitates integration of remote diverse resources
Controllable -power injected where needed No stability distance limitation Proven technology Facilitates power wheeling to HVDC Back-to-Back
