Addendum-VI reverses Zone VI error and switches Sirkari Bhyol turbine bearings to oil lubrication
8UJVNL has restored the project's IIT Roorkee-derived Zone V seismic basis after an intervening addendum wrongly cited Zone VI, and in the same document replaced water-lubricated guide bearings with babbitted oil-lubricated units with water cooling.
8The bearing change reaches cooling circuits, oil handling, monitoring and maintenance philosophy, so the harder question is how much lifetime auxiliary-system cost bidders must now carry into a 48-month fixed package.

NTPC issues second corrigendum on Simhadri 0.5 MMT coal without resolving 25% versus 10% quantity conflict
8Corrigendum C4 of 11 September supersedes C1 and the original buyer-added terms for the Rs 2 crore EMD Simhadri lot, retaining the right to move ordered quantity by up to 25% at award and again during the contract.
8Technical Specification Clause 3 still carries a plus or minus 10% station band, and with the GeM summary recording no ePBG against ITB Clause 22.0's mandatory 5% PBG, bidders must price a maximum volume and security exposure the documents do not settle.

UPPTCL deletes 'provided by UPPTCL' from transformer rows, forcing Noida GIS bidders to price erection
8Corrigendum-1 has replaced the BOQ for the Rs 112.05 crore Sector-155 substation, removing the entry that let bidders leave installation of the 160 MVA and 63 MVA owner-supplied transformers unpriced, and redefining 33 kV termination kits by interface rather than indoor or outdoor location.
8Submission moved a week to 17 September, but the real exposure is that the contractor now prices commissioning around equipment whose manufacture and delivery stay with UPPTCL, with no project-specific relief formula for late handover.

UPRVUNL converts 640 MW Rihand-Obra pumped storage from BOO to zero-consideration handover after 40 years
8The corrigendum replaces extendable BOO ownership with compulsory transfer to UPRVUNL 40 years from SCOD, in good running condition, free of liens and without transfer price or compensation, while the PBG moves to 5% of the Rs 3,953 crore estimate at Rs 197.65 crore and stays live until 12 months after actual commissioning.
8With nine extensions pushing bids to 12 October and forfeiture possible where the developer's own DPR finds the project infeasible, the test is how banks price terminal transfer beside pre-construction feasibility risk.

OPTCL opens Rs 301 crore HTLS reconductoring with two different estimates in its own records
8The Meramundali–Mendhasal package requires dismantling twin AAAC Moose and stringing twin HTLS on the live 400 kV double-circuit line, plus equipment and bus upgrades at both grid-substation ends, with bids closing 9 October.
8The signed notice states Rs 301,22,38,089 while the portal header reads Rs 3,01,26,70,182, and with outage allocation, tower adequacy and scrap responsibility all unspecified, bidders face a package whose basic commercial reference point is unreconciled.

POWERGRID ties 765kV GIS package SS 185T to a TBCB outcome bidders cannot influence
8The Orai, Patran and Agra extension package requires an exclusive MOU with the lowest evaluated qualified bidder, who receives a contract only if POWERGRID wins the upstream tariff-based bid, while exclusivity bars that bidder and connected entities from supporting rival TSPs.
8Four qualification routes admit manufacturers, collaborator and parent-backed Indian plants and EPC bidders, but with a further 10% ex-works guarantee on Routes 2 and 3 and no quantified compensation if POWERGRID loses, broad access on paper may still leave OEM gatekeeping intact.

NTPC builds six-contractor panel for Rs 300 crore Barh pond ash haulage with no purchase-order guarantee
8The 2026-27 rate contract splits work among up to six AST-01 vendors matching a single L1 price, one part reserved for an SC/ST MSE bidder, with roughly Rs 20 crore placed sequentially and Rs 50 crore as the cumulative ceiling per contractor.
8Payment follows compacted ash certified by the receiving road authority rather than trips or weighbridge tonnage, and with variation from minus 100% to plus 20%, panel entry buys eligibility rather than revenue.

GPCL risk-management RFP carries three submission deadlines and a hard copy that overrides the portal
8The ERM consultancy for GPCL's renewable, BESS, green hydrogen, mining and transmission portfolio records online closing at 18:00 on 21 September on the portal, 3 October in Chapter 1 and physical receipt on 6 October, with clause 5.3.2 giving the posted copy precedence.
8The QCBS 70:30 structure is designed to protect technical quality, but a compliant bidder could still be rejected for following one official instruction over another unless GPCL clarifies which date and channel govern.

MPPTCL bars partial bids on Rs 316 crore Sabalgarh package spanning substation, 34 km line and LILO
8TR-28/2026 bundles a new 400 kV substation, a Quad Moose double-circuit link to Morena Pooling and about 21 km of 220 kV LILO into one indivisible turnkey award, with 30-month and 24-month completion tracks and no rainy-season relief, while three 500 MVA and two 200 MVA transformers and two 125 MVAR reactors stay outside contractor supply.
8Price variation reaches only selected equipment and civil work, so reverse-auction pressure will meet a large block of fixed-price and deemed-inclusion exposure.

NTPC Lara mine-filling tender contradicts itself on diesel escalation and soil-cover thickness
8The Rs 255.06 crore package moving 20 lakh MT of ash into the Bishrampur and Dugga pits says no extra payment for fuel-rate changes at condition 2(h), then indexes 25% of contract price to diesel at Clause 14, while Scope Clause 1 fixes a 500 mm soil cap against Payment Clause 9(i)'s 300-500 mm band.
8With quantity variable from minus 100% to plus 20% across a six-way split and no order-of-precedence statement, both conflicts sit directly on the lump-sum price.

APCPL admits Talabira coal in one clause and excludes OCPL in another for 5 LMT Jhajjar buy
8The invitation for bids for the Rs 5 crore EMD package bars coal from CIL, SCCL, OCPL and NTPC group mines, while Technical Specification Clause 2 expressly permits OCPL and Talabira sources including the NLCIL captive mine.
8A second gap sits between Annexure-B1's 4,300 Kcal/kg ceiling and Clause 11's payment cap at 4,000 Kcal/kg, leaving a bidder unable to know whether its declared source qualifies or its better coal can be monetised.

MSEDCL grants nine days on Rs 97.87 crore cable tender but holds firm price against five bidders
8Shriram Cables, Torrent Electricals, Dynamic, KEI and Tirupati each sought price variation on the 33 kV and 11 kV 300 sq.mm HT XLPE package, and MSEDCL answered every request with "as per tender documents," also refusing KEI's three-month first-lot request and Tirupati's insurance surety bond proposal.
8Bidding moved from 1 September to 10 September, leaving a nine-month firm-price delivery, a 20% two-month mobilisation obligation and 1% weekly LD untouched.

OPTCL forces single award across Palaspanga and Barbil while its notice repeats the EMD as the estimate
8The Rs 315.27 crore package makes Lot-I and Lot-II one indivisible contract covering GIS at both stations, 1.2 Rkm of underground cable and roughly 69.2 Rkm of 220 kV overhead line including Twin Moose on 400 kV towers, all in 24 months.
8The opening notice states the estimate as Rs 3.15 crore, exactly the EMD figure, and Table-A carries 10 August against the portal's 11 August, leaving bidders to rely on portal precedence for basic commercial approvals.

HPPCL seeks green hydrogen offtakers for 1 MW Dabhota plant without naming volume, purity or delivery point
8The EOI sets a Rs 1 EMD, zero form fee and Rs 2,360 processing charge, with closing on 13 August and cost opening one hour later, but does not state saleable output, pressure, metering ownership, custody transfer or contract tenure.
8Classified simultaneously as procurement of services and miscellaneous works with a scheduled cost opening, the notification leaves respondents unsure whether they are quoting a purchase price, a service charge or a bundled logistics proposition.

NTPC leaves three quantity formulations live across its 2.5 MMT five-station coal package
8The Telangana lot under CS-0011-011(10)-9 now carries a plus or minus 20% variation in the revised detailed document, plus or minus 10% in the separate technical specification and a 25% GeM option clause at both order placement and during contract.
8Sequential station opening means a bidder's later price bids stay unopened once it reaches its declared Annexure-TC-10 limit, making award appetite a live competitive variable before any price is compared.

NTPC cuts Tanda coal ceiling to 3,700 Kcal/kg while lifting initial payment to 80%
8Revised Annexure-B1 pulls the GCV envelope down from 4,300 Kcal/kg, ash from 50% to 45% and moisture to seasonal caps of 12% and 14%, and the GCV challenge window contracts from ten working days to seven calendar days with a ±71.7 Kcal/kg admissibility threshold.
8The move from 50% to 80% initial payment is the clearest contractor gain in the package, but it arrives alongside ±20% quantity variation, station diversion rights and a source pool narrowed by the tighter specification.

Nabinagar sits last in NTPC's price-opening order, exposing it to a thinner field
8Corrigendum-1 leaves the 16 September dates unchanged for the 0.5 MMT lot and fixes the opening sequence as Telangana, Simhadri, Mouda, Tanda and Nabinagar, with bid security shown at Rs 10 crore for five stations against a visible overwritten Rs 8 crore in ITB Clause 7.1.
8Because bidders reaching their declared award ceiling drop out before later envelopes are opened, the last station in the queue may face the weakest price competition regardless of its own economics.

NHPC inserts a missing crane chapter and cuts turbine efficiency threshold to 94% at Dulhasti Stage-II
8Corrigendum No. 1 added the absent Chapter 18 covering two 190/30-tonne powerhouse cranes and three others, Corrigendum No. 5 rewrote the cooling-water and HVAC chapters and lowered the non-responsiveness threshold from 94.5% to 94%, and price-adjustment indices moved from 2011-12 to 2022-23.
8Four extensions have taken submission from 24 July to 28 September on the Rs 496.90 crore package, yet unit commissioning stays fixed at months 43 and 44 from the civil zero date.

UJVNL lets two OEMs cover turbine and generator at Tiuni Plasu after 18 extensions
8Addendum-II moved qualification from turbine and generator to turbine "and/or" generator and deleted the contract-value experience thresholds, and Addendum-VI then allowed as many as two manufacturers, with force-majeure substitution limited to BHEL, Voith Hydro, Andritz Hydro and General Electric.
8Addendum-III deleted air-gap, partial-discharge and vibration monitoring and cut excitation redundancy from n+n to n+1, so the widened front door arrives with a thinner reliability margin and a Rs 260 crore turnover test for manufacturer-backed bidders.

JERC bars consultants holding two of three earlier awards from Chandigarh STU-SLDC tariff work
8The Rs 18 lakh QCBS assignment covering business plans, MYT petitions, mid-term review and true-ups to FY 2029-30 excludes firms already awarded two of three specified JERC bids, while demanding ten years of experience, 20 assignments worth Rs 1 crore and two staff stationed at the Commission.
8Corrigendum C3 warns that a participation fee can render the bid null and void, even though the underlying RFP still requires a Rs 10,000 processing fee and advance hard copies.

SECI moves Ramagiri wind auction to cost per certified MU and drops turbine floor to 2.7 MW
8Amendment-01 rewrites ITB Clause 32.4.1 so bids rank on EBV divided by NIWE-certified ten-year P90 generation, with the denominator locked before the reverse auction and only price free to move, while the power-curve pass mark falls from 98% to 95% and the 96-hour test threshold from 98% to 96%.
8Repeated STPT failure no longer triggers WTG rejection and refund with 13% interest but a generation-linked LD at Rs 4.5 per kWh, leaving yield certification quality as commercially decisive as the EPC quote.

NPCL wants 300 MW RTC with 90% availability in six peak hours it picks day-ahead
8The 25-year BOO procurement requires a declared annual CUF of at least 75% held within plus or minus 10%, 50% of contracted capacity in every off-peak 15-minute block and 90% across six peak hours selected by NPCL on a day-ahead basis, with shortfall damages at 1.5 times tariff.
8Configuration and delivery points may change until financial closure but bring no SCSD relief, so the 24-month schedule and daily PBG encashment will likely surface as a firmness premium in the discovered tariff.

NTPC narrows Mouda coal window to 3,700 Kcal/kg as second corrigendum lands five days before bids close
8Corrigendum C4 of 11 September supersedes C1 for the 5 lakh MT package, while the revised document cuts maximum GCV from 4,300 Kcal/kg, ash from 50% to 45% and moisture to seasonal 12% and 14% caps, and moves payment from 50:40:10 to 80:10:10 with sampling charges down to Rs 2.97 per MT.
8GeM records no ePBG and no arbitration against Clause 22.0's 5% security and a Delhi-seated GCC arbitration, leaving document precedence to carry more commercial weight than the headline tonnage.

APEPDCL grants 24 extra days on its Rs 143.32 crore SCADA package without touching a single execution obligation
8Three corrigenda moved submission from 1 September to 25 September 2026, but the 18-month implementation period, five-year FMS and 10% performance security stayed exactly where they were.
8What the extensions really concede is preparation time for a bidder pool that must satisfy two separate qualification streams and assemble OEM authorisations before it can quote.

RVPN's Rs 83.38 crore Shiv Enclave GIS package makes unlisted work the contractor's problem
8A 132/33 kV, 2x80 MVA GIS substation with a 4 km LILO cable arrangement carries a 545-day execution period and a 10% performance security, extended eight days by Corrigendum No. 01.
8The clause that matters is GCC 3.2, which absorbs reasonably inferable items into the contractor's scope without automatic additional payment.

NTPC puts 2,184 man-months of construction safety at Telangana Stage-II behind a 52-month firm-rate contract
8The consultant must field 47 personnel, run a 24/7 IP-camera control room and approve other agencies' JSA/HIRA documents across a 3 x 800 MW build.
8The commercial risk is not the Rs 5,000-per-day non-deployment penalty but firm rates through a unilateral 12-month extension, 5% retention and no interest on deferred payment.

TNPDCL asks for 5,000 distribution transformers while the protected BOQ shows a quantity of one
8The M-256 tender covers 5,000 units of 100 kVA, EEL-2 aluminium-wound transformers with a Rs 1,00,20,500 EMD, a ±25% quantity variation and a 60-month guarantee.
8The BOQ's "1.0 No." line and its residual civil-work text sit inside a spreadsheet bidders are forbidden to alter, converting a template artefact into a responsiveness risk.

JdVVNL's Rs 119.89 crore Bikaner package carries two completion periods inside the same document
8The NIT records eight months for supply, erection, testing and commissioning while Appendix 4 records nine, both against an unchanged nine-month total, with the portal and NIT also differing on the 22 September opening time.
8Performance security is quoted at both 180 days and 30 days beyond the defect-liability period, and guarantee charges turn on which one controls.

Bidder queries force JdVVNL to reopen the BOQ on its Rs 91.47 crore Bikaner DD package before bids close
8Corrigendum-3 supersedes the 14 August NIT, revising the BOQ, specifications, estimate and EMD to Rs 1.83 crore without publishing the superseded figures for comparison.
8The sharper problem is composition: JdVVNL's own estimate puts supply at 79.6% of value while ITB 37 treats supply above 70% of the quoted price as front-loaded and demands additional security.

Phalodi package climbs 0.7% across two corrigenda, with the entire increase landing in supply
8Between Corrigendum-I and Corrigendum-3, supply rose by Rs 38.89 lakh while erection fell by Rs 1.21 lakh, taking TNTW-792 to Rs 97,59,20,302.39 and EMD to Rs 1,95,18,407.
8No item-level change register accompanies the revision, and the portal and SBD still disagree on whether technical bids open at 11:00 am or 5:00 pm.

Jaisalmer's Rs 121.13 crore RDSS package stacks four separate security layers on one contractor
8Beyond the 10% performance security sit abnormal-bid security, supply-unbalancing security and a further 10% guarantee on major equipment running to 36 months after completion.
8With 77.4% of the estimate in supply and no pre-bid meeting scheduled, bidders must also decide whether the EMD instrument reads Rs 2,42,25,139 or Rs 2,42,25,140.

JVVNL withdraws the vendor-registration security waiver as it tenders 25,000 CSP transformers
8Appendix-A replaces EMD and SBG references with Bid Security and removes the relaxation that JVVNL registration alone previously conferred, on a Rs 16,025 lakh, 16 kVA programme.
8The allocation formula caps L1 at 20% and spreads half the quantity across other firms, making past repair performance an eligibility filter rather than a reference note.

Navkar Global Infra takes NTPC Mouda ash transport at 47.6% of base rates against 23 other accepted bidders
8The accepted percentage produces a Rs 142.80 crore contract value, a 52.4% discount to the Rs 300 crore estimate and far past NTPC's own 10% abnormally-low threshold.
8Section C nonetheless caps each shortlisted bidder at Rs 50 crore cumulative and guarantees no purchase order at all, separating the headline award from bankable work.

Churu package falls Rs 7.45 crore in Corrigendum-3 after rising in Corrigendum-1 TNTW-798 moved from Rs 132.60 crore to Rs 133.13 crore and then down to Rs 125.67 crore, with supply cut 6.5% against erection's 2.0%, and no clause-level reconciliation published.
8Bidders have ten calendar days from republication to reprice, while the portal and corrigendum differ by Rs 60 on an EMD that decides envelope-one compliance.

UJVN Limited raises its BESS tariff ceiling 3.8% but leaves 165 MWh outside VGF support
8The 90 MW/225 MWh Chilla project draws VGF on only 60 MWh, while the ceiling capacity charge moves to Rs 3,30,400/MW/month against the Rs 3,96,747 bidders sought.
8After 12 years the entire asset transfers to UJVN Limited without consideration, so residual value has to be recovered inside a capped tariff stream.
