Unsigned Power Purchase Agreements (PPAs) represent a structural bottleneck in India's renewable energy transition. Analyse the causes and suggest a multi-pronged resolution framework.

Q. Unsigned Power Purchase Agreements (PPAs) represent a structural bottleneck in India's renewable energy transition. Analyse the causes and suggest a multi-pronged resolution framework. (15 marks, 250-350 words)

A PPA is the bankable contract by which a distribution company commits to buy power; without it, auctioned capacity cannot achieve financial closure. India's 500 GW non-fossil target therefore turns less on auction volumes than on offtake — and it is precisely here, with a large block of centrally awarded capacity still awaiting State commitments, that the transition is stalling [1].

Causes of the offtake gap - DISCOM insolvency: loss-making utilities with delayed subsidy receipts are reluctant to assume 25-year purchase liabilities; the Revamped Distribution Sector Scheme's turnaround remains incomplete. - Tariff expectations: with module costs falling, buyers defer signing in anticipation of cheaper future bids. - Profile mismatch: solar peaks in daytime while State demand peaks in the evening, so plain solar PPAs are less useful than firm and dispatchable supply. - Grid and transmission constraints, acknowledged as a live challenge by the Ministry of New and Renewable Energy [1]. - Weak obligation enforcement: Renewable Consumption Obligations rise to 43.33% by 2029-30, but State regulators rarely impose credible penalties [3]. - Federal design gap: capacity is auctioned centrally by REIAs such as SECI, while procurement is a State decision under the Electricity Act, 2003.

A multi-pronged resolution framework - Fiscal: link States' incentives and interest-free capital loans to RE adoption and PPA signing — a policy accepted by the Finance and Power Ministries [1]. - Regulatory: enforce the RCO trajectory [3] and operationalise the Carbon Credit Certificate framework to price non-compliance [1]. - Technical: shift to storage-linked and round-the-clock tenders and accelerate green-corridor transmission. - Financial: restore DISCOM viability through tariff rationalisation, direct benefit transfer of subsidies and payment-security mechanisms. - Distributed demand creation: PM Surya Ghar, with 23.9 lakh households and 7 GW installed [4], backed by MNRE's ₹32,915 crore outlay for 2026-27 [2].

Unsigned PPAs are thus a governance and financial problem, not a technological one. Aligning State fiscal interest with national climate obligation converts a coordination failure into cooperative federalism, keeping India's Paris commitments and energy security on track.
