PFC Consulting has launched competitive bidding for the 400 kV Bhojrajka (Khushkhera) intra-state transmission substation in Rajasthan, a key enabler for evacuating over 25 GW of existing and planned solar and wind capacity in the state’s northern renewable corridor. The tender signals accelerated execution of Rajasthan’s intra-state transmission plan, which has lagged inter-state green corridor build-out and now risks becoming a bottleneck for projects already under construction. For developers and financiers, the project’s progress will directly determine whether commissioned renewable capacity can reach load centres without curtailment.
Rajasthan’s Intra-State Transmission Gap Comes Into Focus
Rajasthan leads India in installed renewable capacity, with roughly 27 GW of solar and wind operational as of early 2025, but its intra-state transmission network has not kept pace with the inter-state green energy corridors built by Power Grid Corporation. The state transmission utility, Rajasthan Rajya Vidyut Prasaran Nigam (RVPN), has historically relied on state-budget funding and cost-plus regulation, which slowed project cycles to 4-5 years from concept to commissioning. The shift to tariff-based competitive bidding (TBCB) for intra-state projects – mandated by the Ministry of Power’s 2021 guidelines – aims to compress that timeline to 24-30 months and attract private capital.
The Bhojrajka substation sits in Alwar district, approximately 70 km northeast of Jaipur and adjacent to the Delhi-Mumbai Industrial Corridor (DMIC). This geography is deliberate: the substation anchors a cluster of solar parks and wind-solar hybrid projects in the Bhadla-Fatehgarh-Phalodi belt to the west and the rising demand centres of the National Capital Region (NCR) to the northeast. RVPN’s latest transmission plan identifies 14 new 400 kV and 220 kV substations and roughly 3,200 circuit-kilometres of associated lines to be bid out through 2027. Bhojrajka is among the first to reach the market under the new TBCB framework for intra-state assets, making its bidding trajectory a template for the rest.
PFC Consulting, a wholly owned subsidiary of Power Finance Corporation, acts as the bid process coordinator (BPC). Its role includes finalising the request for qualification (RFQ) and request for proposal (RFP) documents, managing the two-stage bidding process, and recommending the selected bidder to RVPN for the transmission service agreement (TSA). The BPC model – already standard for inter-state projects – is now being replicated at the state level to standardise documentation, reduce regulatory risk, and improve bankability. The tender documents are expected to specify a 35-year TSA tenure, availability-based revenue with no merchant exposure, and a build-own-operate-maintain (BOOM) structure transferring assets to RVPN at the end of the concession.
Why This Substation Matters Beyond Its Own Footprint
The Bhojrajka award will test whether private developers view intra-state TBCB assets as creditworthy as inter-state projects. Inter-state transmission SPVs sponsored by Sterlite Power, Adani Energy Solutions, and IndiGrid have consistently achieved debt-to-equity ratios of 75:25 at spreads of 120-150 basis points over the 10-year G-sec, thanks to central-government-backed payment security mechanisms. Intra-state TSAs historically lacked a comparable payment security fund, forcing lenders to price in state-utility credit risk. Rajasthan has now committed to establishing a state-level payment security mechanism – a revolving letter of credit backed by a budgetary allocation – but its operational track record is unproven. If the Bhojrajka bid attracts three or more qualified bidders and achieves a levelised transmission charge below ₹1.20 per kWh (roughly the inter-state benchmark for comparable voltage and length), it will validate the new framework and de-risk the remaining 13 substations in the pipeline.
That points to a broader shift: state transmission utilities across India – Maharashtra, Gujarat, Karnataka, and Tamil Nadu – are watching Rajasthan’s TBCB rollout closely. Collectively, these five states account for over 60 % of India’s renewable capacity additions targeted for 2025-2030. If Rajasthan demonstrates that intra-state assets can be financed on inter-state terms, the addressable market for private transmission capital expands from roughly ₹40,000 crore (inter-state only) to over ₹1.2 lakh crore including intra-state projects through 2030. Conversely, a weak response or aggressive tariff quotes that later prove unsustainable would reinforce the perception that state utilities remain quasi-sovereign risks requiring explicit central guarantees.
By comparison, the 400 kV Fatehgarh-Bhadla inter-state corridor – commissioned in 2022 – achieved a levelised tariff of ₹0.85/kWh and attracted 14 bidders at the RFQ stage. Bhojrajka’s shorter line lengths (approximately 120 km of 400 kV D/C and 80 km of 220 kV D/C) and lower terrain risk should theoretically support even lower tariffs, but the absence of a central payment guarantee introduces a risk premium that bidders will price in. My estimate: the winning quote will land between ₹1.05 and ₹1.25/kWh, with the spread largely reflecting each bidder’s assessment of Rajasthan’s payment security fund credibility.
Who This Affects
- Utility planner (RVPN / state load dispatch centre): The substation’s commissioning schedule – likely 30 months from TSA signing – must align with the 4.5 GW of solar-hybrid projects in the Bhadla-Phalodi corridor that have signed PPAs but lack firm evacuation paths. Any slippage beyond 2027 forces curtailment or costly interim arrangements.
- Renewable developer (solar/wind/hybrid): Projects in the 2024-2026 bidding tranches (SECI Tranche XV, XVI, and state-specific auctions) have banked on Bhojrajka and the associated 400 kV Bhadla-Bhojrajka line for evacuation. Developers should model a 6-9 month buffer beyond the TBCB timeline and negotiate PPA force-majeure clauses that recognise transmission delay as a qualifying event.
- Transmission investor / infrastructure fund: The bid offers a rare pure-play intra-state transmission asset with 35-year contracted revenue. Funds should stress-test cash flows under a scenario where RVPN delays payments by 60-90 days – the historical average for Rajasthan discoms – and verify that the payment security fund covers at least three months of annuity.
- Policy analyst / regulator (CERC / RERC): The project is the first major test of the 2021 TBCB guidelines for intra-state transmission. Regulators should monitor whether the bidding documents adequately allocate change-in-law risk (e.g., future GST rate changes, right-of-way compensation revisions) to the off-taker rather than the SPV, a common point of contention in inter-state projects.
What to Watch Next
- RFQ issuance and pre-bid conference attendance: A turnout of 10+ prospective bidders at the pre-bid meeting would signal strong appetite; fewer than six suggests the market is pricing in unmitigated state-utility risk.
- Payment security fund operationalisation: Rajasthan’s finance department must notify the fund’s corpus (target: ₹500 crore initial) and governing board before the RFP deadline. Delay here will compress bidder due-diligence windows and likely push out the bid submission date.
- Right-of-way (RoW) clearance status for the 400 kV D/C line: The 120 km corridor crosses agricultural land in Alwar and Bharatpur districts. RVPN’s advance acquisition of 80 % of the RoW corridor before TSA signing would be a strong de-risking signal; anything below 50 % shifts significant schedule risk to the SPV.
- Levelised transmission charge at bid opening: A winning quote above ₹1.30/kWh would indicate the market demands a 30-40 % risk premium over inter-state benchmarks, implying the remaining intra-state pipeline may struggle to attract competitive tension without additional credit enhancement.
Bottom line: The Bhojrajka tender is not just another substation – it is the proof-of-concept for private capital in Rajasthan’s intra-state transmission build-out. Its bidding outcome will set the pricing and risk-allocation template for the next decade of state-grid investment across India’s renewable-rich states.
