One Sun One World One Grid
“One Sun One World One Grid Is an innovative idea or a vision to integrate renewable energy resources of 140 countries. This global grid plan will be leveraging the member countries of International Solar Alliance. To begin with India will be at the pivot, the solar spectrum would be divided into two broad zones viz. far East which would include countries like Myanmar, Vietnam, Thailand, Lao, Cambodia etc. and far West which would cover the Middle East and the Africa Region.
OSOWOG framework attempts to create a real time market, which can be utilized by neighbouring countries. This can be a reality only if we use a mix of solar, wind, hydro and even tidal, combined with battery technology developments, thus providing impetus to strategies on decarbonization globally and also ensuring the effective utlisation of such big infrastructure investment. Approximately 44 GW of electricity exchange is expected by 2036/2040 inter-country grid may be through OSOWOG or Bilateral exchanges.
However the challenges lie in grid vulnerability to accidents, weather, political will, inter country metering regulations, terrorist threats and cyber-attacks. Even dispute redressal issues such as non-payment of dues,etc.
The challenges to be addressed by OSOWOG framework also would be high operating expenses of creating a huge grid infrastructure like synchrnosous/ Asynchrnous (HVDC) and its LCOE comparatives vis a vis storage facility at local power generating plants looking into the scenario that by the time the OSOWOG grid is ready,the storage cost will further come down; decision on inter country / group country load despatch control (something similar to POSOCO) centre for energy data exchange and finally the Open access/ third party transfer rules, tariff determination and wheeling charges issues.
It should be endeavoured to assess that how OSOWOG can also be utlised for addressing grid balancing issues, ancillary services for frequency and reactive power regulation looking into the intermittency nature of renewables. However ambitious OSOWOG framework may sound at present, but this vision can support other auxiliary issues faced by countries namely desalination, potable water crisis, complete electrification, and transport electrification.” - Refer pg 36 of the June'20 Issue of Solar Quarter Magazine
