Cross-Border Electricity Trade between India and Sri Lanka: Impact on Power System Operations

Abstract

U.S. Department of Energy (DOE) reports produced after 1991 and a growing number of pre-1991 documents are available free via www.OSTI.gov.

Cross-Border Interconnectors in South Asia: Market-Oriented Dispatch and Planning

“…• The estimates of benefits in general corroborates those obtained in prior studies [4][5][6][7][8][9]. In fact, the short-term benefits in some cases have increased substantially (e.g., doubled for India-Sri Lanka relative to [4]).…”

“…Recent findings from SARI/EI [7] confirms significant long-term benefits of such integration including large capital expense (capex) savings for the region of $17b as well as cumulative CO2 savings of 120 mt by 2045. More recently, NREL conducted two studies for India-Nepal [8] and India-Sri Lanka [9]. The first study [8] was conducted for 2022 and estimated a savings of $359 million for the year from 4.5 GW hydro development in Nepal.…”

“…The first study [8] was conducted for 2022 and estimated a savings of $359 million for the year from 4.5 GW hydro development in Nepal. The second study [9] conducted for 2025 estimated savings from India-Sri Lanka line at $180 million (for one year).…”

“…The significance of short-term benefits, notwithstanding the fact that these are based on historic rather than forward looking prices, provides a high degree of comfort and alignment with views expressed for at least a decade [2][3][4][5][6][7][8][9]. Analysis for India-Sri Lanka adds a further impetus in light of the fact that annual benefit estimates reported in [4, p.10] was $186 pa which has now more than doubled to $383 million (Table 2), as planned generation capacity additions in SRI have not eventuated.…”

Power Sector Decarbonization in South Asia: Pathways for Research, Modeling, and Implementation

“…A substantial amount of research has already been performed to help understand the grid of the future, both in India, South Asia, and globally. Studies such as Palchak et al (2017), McBennett et al (2019, Rose et al (2018) helped in understanding the challenges that may be faced in operating India's grid with 175 GW of renewable energy. Additional work on cross-border electricity trade in the region helped clarify how India's renewable energy ambitions would impact regional opportunities (McBennett et al 2019;Joshi, Hurlbut, and Palchak 2020).…”
