To bridge the gap between Rajasthan's surplus solar potential and Bihar's energy deficits, we need more than just wires; we need smarter financial rules. One practical mechanism involves Inter-State Transmission System (ISTS) waivers. If Rajasthan's grid operators receive subsidies for transmitting surplus energy to Bihar, the cost of moving that power drops. This makes the electricity cheaper for Bihar's end-users, directly tackling local energy poverty.
We could also implement Green Energy Open Access (GEOA) models with a twist. Under this framework, developers in Rajasthan could sell power directly to Bihar's state distribution companies (DISCOMs) through a regulated cross-border market. To ensure this benefits the poor, a portion of these transaction fees could fund Direct Benefit Transfer (DBT) schemes for Bihar's low-income households. It creates a cycle where excess sunlight in the West becomes affordable light in the East.
Finally, implementing Renewable Purchase Obligations (RPO) with a geographic carve-out would work well. If Bihar is required to buy a set percentage of its power from specific wind or solar hubs in Rajasthan, it creates a guaranteed market. This stability encourages private investment in transmission infrastructure. It turns wasted, curtailed megawatts into reliable, life-changing power for millions.
