India's ₹1.86 lakh crore plan to move renewable power

What does it mean to evacuate power?

In power, "evacuation" means moving electricity from where it's generated to where it's used. A solar farm in Rajasthan is useless if the wires can't carry that power to cities like Delhi or Mumbai. The wires are the evacuation system. This scheme builds those wires so renewable power can actually reach homes.

Why batteries and not just more wires?

Wires move power from one place to another, but they cannot store it. Solar and wind output varies, so batteries hold excess power made during sunny and windy hours and release it in the evening when demand peaks and renewable generation drops, keeping the grid balanced.

Where does the money for this scheme actually come from?

The central government contributes ₹54,082 crore of the ₹1.86 lakh crore outlay, with the rest funded through tariff-based competitive bidding and cost-plus contracts, where private transmission service providers recover costs through tariffs paid by consumers. State transmission utilities implement the scheme, and the central support is designed to offset transmission charges, which the government says lowers power costs for consumers. Our read: the ₹1.32 lakh crore balance is ultimately paid by electricity users through tariffs; the centre's contribution merely cushions that cost.

What happens to the power if the grid isn't built in time?

Without adequate transmission, renewable projects face curtailment, meaning generated power is simply wasted. The government's own presentation stressed that transmission capacity must come ahead of renewable projects to prevent this. Delays in lines, often from forest clearances and land acquisition, push up tariffs because bidders factor in penalty risk. That curtailment risk is why the scheme finances lines in advance of generation. Our read: any renewable plant built before its evacuation line is ready will lose revenue, and those losses ultimately get priced into future bids.

What stops a private firm from walking away midway?

Transmission firms under the scheme sign a transmission service agreement that locks them into the project. If they delay, they pay liquidated damages and forgo tariff for the delay period. If the associated power plant is abandoned, a proposed foreclosure clause lets the contract be terminated with compensation to the developer. The regulator has also proposed a quarterly performance index: four straight poor quarters would bar a firm from bidding on new projects, deterring walkouts while keeping existing obligations intact.

Who pays if the transmission line ends up underused?

The transmission service provider bears the initial loss: under tariff-based competitive bidding, it wins a contract to build a line and is paid through tariffs only if the line actually carries power. If the renewable plant it was meant to serve is abandoned or delayed, the line sits idle, and the provider gets no revenue. The regulator has proposed a foreclosure clause to terminate such contracts with compensation, and the government's own presentation warns that without adequate transmission, renewable power faces curtailment, meaning generated energy is wasted. Our read: the cost of a stranded line falls on the private developer, who prices that risk into its bid, which then lands on consumers through higher tariffs.

What happens to consumers when a line is built but never used?

The private developer bears the loss initially: under tariff-based competitive bidding, a transmission service provider is paid through tariffs only if the line actually carries power. If the associated renewable plant is abandoned or delayed, the line sits idle with no revenue. The regulator has proposed a foreclosure clause that lets the contract be terminated with compensation to the developer, and tariffs are set to cover such risks. Our read: ultimately consumers pay for stranded lines through higher tariffs on other projects, as developers price this risk into every bid.

How big is ₹1.86 lakh crore?

₹1.86 lakh crore is ₹1,86,405 crore, or roughly $22 billion. It covers the full project outlay, with ₹1,36,378 crore for transmission lines and ₹50,000 crore for battery storage, while the central government's own contribution is ₹54,082 crore.

What happens if the transmission lines are delayed?

Under tariff-based competitive bidding, bidders are penalized for delays through liquidated damages and forgoing tariff for the delay period, which pushes up bid prices, as developers factor in that risk. CERC has proposed a foreclosure provision: if an associated generation project is abandoned, the transmission contract can be terminated with compensation to the developer. The risk of delays from forest clearances and land acquisition is why CERC has recommended simpler bidding documents and pre-fixed end coordinates to avoid disputes. Our read: delays are priced into tariffs, so consumers ultimately absorb the cost of grid delays.

Why is the grid the bottleneck now?

Solar and wind power only flow when the sun shines or the wind blows, but the grid was built for steady, predictable coal power. So when renewables surge, the wires can get congested, or the power gets wasted because it can't reach anyone. The new scheme builds transmission lines and batteries so grid capacity comes before renewable projects, not after, as minister Ashwini Vaishnaw said.

Who pays for the scheme?

The scheme's total cost is about ₹1.86 lakh crore. The Centre provides ₹54,082 crore in financial support to offset transmission charges. Private companies build and run lines, recovering costs through tariffs, with consumers ultimately paying via electricity prices.

Why does the bidding method for new lines matter to consumers?

New or greenfield lines under the scheme are awarded through tariff-based competitive bidding, where companies bid to build and run the lines and consumers pay via tariffs. Evidence from earlier projects shows competitive bidding typically yields tariffs about 30-40% lower than the cost-plus method used for upgrades. Lower bids mean lower transmission charges passed to consumers, which is why the government chose this route for new projects to keep power costs down. Our read: the bidding method is the main lever the government has to control what consumers ultimately pay.

Can the bidding method for new lines keep working as more projects are awarded?

TBCB has delivered tariffs 30-40% lower than cost-plus, but evidence shows the method has structural vulnerabilities. Bidders face delays from forest clearances, land acquisition, and changing end coordinates, which they factor into bid prices, pushing tariffs up. The CERC has flagged that penalties for delays are currently built into bids, and that project documentation often leaves route surveys and termination points unclear. Our read: the government's cost advantage from TBCB depends on fixing these friction points, not just awarding more projects.

What happens if a TBCB project is delayed or stranded?

The evidence describes two kinds of failures. If a project is delayed, the transmission licensee must pay penalties in the form of liquidated damages and forego tariff, but bidders factor this risk into their bid prices, which pushes tariffs up. If the associated generation project is abandoned, the transmission line gets stranded with no consumer, and the CERC has recommended adding a foreclosure provision to allow contracts to terminate with compensation. Our read: without such protections, bidders price in worst-case risks, and the cost savings from TBCB shrink or vanish entirely.

What stops a line developer from gaming the bidding system?

The CERC has proposed a quarterly performance index for every TBCB project. If a licensee performs poorly for four straight quarters, it would be disqualified from bidding on new projects. The commission also wants random inspections every three months to check equipment quality, and has flagged that a licensee can currently claim a deemed commercial operation date and charge tariffs even when upstream or downstream assets are not ready. Our read: the real check on gaming is the threat of being locked out of future projects, not penalties on a single delayed line.

What happens if the project documents themselves are flawed from the start?

The CERC has flagged that bidding documents often leave route surveys and end coordinates fuzzy, so bidders who win a line may discover forest clearances or rerouting needs later, pushing up costs and tariffs. The regulator has recommended that survey reports be excluded from bids, end coordinates fixed upfront, and project nature clearly specified to avoid disputes over who pays. Until those fixes are institutionalised, the lower tariffs from TBCB remain fragile. Our read: the scheme's cost advantage depends on bidding documents being tightened, not just on competition.

How does the regulator's plan actually enforce quality on the ground?

The CERC has recommended a quarterly performance index for every TBCB project. If a licensee performs poorly for four straight quarters, it would be disqualified from bidding on new projects, which deters developers from cutting corners. The commission also wants random inspections every three months to check equipment and workmanship against grid standards. Our read: the enforcement teeth are the threat of being locked out of future bids, not penalties on a single delayed line, because the licence-cancellation process is too slow to matter.

What happens if solar grows faster than wires?

If solar grows faster than wires, power gets curtailed: generated solar energy is wasted because transmission lines can't carry it to consumers. The government's own presentation said inadequate transmission causes curtailment, which is why it insists grid infrastructure must precede new renewable capacity, not follow it.

Is 135 GW a lot of power to move?

Yes, 135 GW is huge: it's over a quarter of India's total 500 GW power capacity, and it's only the renewable power the new lines will carry. For scale, India's entire solar capacity was 162 GW by mid-2026.
