Goa’s electricity demand is set to surge sharply over the next decade, and power sector experts say the State’s transmission network ” not generation ” could emerge as the biggest constraint to reliable electricity supply unless urgent upgrades are undertaken.
According to a Resource Adequacy Plan prepared by the Central Electricity Authority (CEA), Goa’s peak power demand is projected to more than double from 831 MW in 2024“25 to 1,783 MW by 2034“35, while annual electricity consumption is expected to climb sharply from 5,327 million units (MU) to over 10,478 MU. The projected growth rate of nearly 7% per year is significantly higher than earlier national estimates, reflecting rapid urbanisation, commercial activity and changing consumption patterns.
While the State has outlined plans to add generation capacity through a mix of coal, solar, wind and battery storage, power sector experts caution that generation alone will not guarantee reliable supply. Without a parallel and accelerated push to expand and modernise transmission infrastructure, additional power may not reach consumers when it is needed most ” particularly during peak hours.
Goa’s demand profile adds to the challenge. Electricity consumption peaks during the summer months of April and May, driven by higher temperatures and tourism-related activity. More critically, the State records daily peak demand during night hours throughout the year, when solar power is unavailable and dependence on inter-state power flow increases. This places sustained pressure on transmission corridors and substations, especially during evening and night-time peaks.
Industry expert and independent researcher Saddaf Alam said, “Demand growth of this magnitude cannot be managed through generation planning alone. Transmission is the backbone of energy security. If the grid is not strengthened in advance, even surplus power available in other States will not be accessible when Goa needs it most.”
“The next phase of power sector reform must treat transmission as strategic infrastructure, not an afterthought. Strengthening inter-state corridors and modernising substations is essential for Goa to remain energy-secure in a high-demand future,” he further added.
The study also warns that with existing and planned arrangements, Goa could face unserved energy of up to 4,921 MU by 2034“35, amounting to nearly 47% of projected annual demand in that year. While the modelling assumes no transmission bottlenecks, experts point out that real-world constraints ” including congestion, outages and right-of-way challenges ” could exacerbate supply risks if grid upgrades lag behind demand growth.
Energy analysts stress that transmission expansion is not just a technical requirement but a policy imperative. “If Goa wants reliable, round-the-clock power ” especially as renewable energy forms a larger share of the mix ” the grid has to be the priority now,” said an energy analyst. “Transmission projects take years due to planning, land acquisition and right-of-way clearances. Delays today will translate into shortages tomorrow.”
By 2034“35, non-fossil fuel sources are projected to account for around 61% of Goa’s contracted capacity, increasing the need for a flexible and resilient grid capable of handling variable renewable energy. Experts also note that Goa may experience surplus power during solar hours in monsoon months, which could be shared with other states ” but only if adequate transmission capacity exists.
Power sector observers say early investment in transmission expansion, modern substations and stronger inter-state connectivity will help Goa manage rising demand at lower long-term cost. As electricity needs grow rapidly, they argue, the state’s energy future will depend not just on adding megawatts, but on building the transmission backbone required to deliver them safely, reliably and on time.
