Record growth, BESS missed, capex upgraded, duck-curve conviction unshaken
The verdict, the claims that held up, the sharpest analyst exchanges, and the risks — the earnings call, decoded from the transcript.
Hold
confidence 7/10
Grade B
Beat guidance on YoY growth % (67.8% vs 63% claimed) but reported revenue overstated (₹954 vs ₹857.5 delivered); BESS Q1 commissioning missed 4 GWh target.
Optimistic
next 1–2 quarters
Very Optimistic
multi-year
Strong growth (+67.8% revenue, +79.9% PAT) delivered; BESS strategy (₹1.4k Cr merchant locked, 3.62 GWh live) validates early deployment bet. However, capex raised to ₹15–20k Cr (2–3x revenue) against backdrop of ₹857.5 Cr actual revenue creates execution and refinancing risk, especially if peak-power merchant spreads compress post-El Niño as GNA delays persist.

Earnings quality
What changed since the last call
BESS commissioning guidance accelerated
UpgradeUpgraded from 10 GWh by calendar-year 2027 to 10+ GWh by fiscal-year 2027 (3-quarter pullforward). Reflects strong procurement, financials locked.
FY27 capex raised 33% at midpoint
UpgradeRaised from ₹15,000 Cr to ₹15,000–20,000 Cr range. Rationale: front-load capex via QIP proceeds to prepone solar GNA, capture lower battery costs.
Portfolio expanded to 8,070 MW
UpgradeWas 7,470 MW (implied prior call); now 8,070 MW, all targeting 20 GWh storage ecosystem. +600 MW FDRE/hybrid PPA signed this quarter.
Debt financing closed for PPA projects
UpgradeINR6,000 Cr tied up for 700 MW FDRE projects; 85% of 3,880 MW PPA portfolio now debt-secured. Reduces refinancing tail risk.
Merchant market thesis sharpened
NeutralINR1,400 Cr locked (70–80% of 10 GWh capacity). Management now expects 10–12 GWh annual merchant capacity permanently (not one-time). Duck-curve demand 300→500 GWh by 2030 per analysis.
The Q&A
Analysts pressed hard on merchant-market depth, BESS cost inflation, capex execution, and peak-power pricing sustainability. Management held firm on duck-curve demand thesis (rooftop solar + KUSUM + EV + air-con driving evening peak) and noted hydro/pump-storage can't cover 4–6 hour peak need. Some hedging on C&I profitability and data-center play (hiring stage, no commitments). Q&A credible but verbose; no evasions detected.
BESS merchant capacity outlook — Subhadip Mitra, Nuvama Wealth
Answered10 GWh by March FY27 end on daily-basis capacity sales. 70–80% locked at INR1,400 Cr revenue (~INR8–10/unit). 600 MW open now, target 0 open by year-end. Going forward, 10–12 GWh annual open capacity.
SJVN project GNA delay risk — Aniket, SBI Mutual Fund
AnsweredBattery already live (Heergarh, Bikaner II); solar GNA June '27. Will operate battery on merchant/short-term till solar ready. No capex on solar modules until GSS ready to minimize IDC.
Battery cost trends — Apoorva Bahadur, IIFL
AnsweredInitial batches lower. Lithium carbonate volatile. INR93 lakh could rise 5–10% within budgeted cost. PCS, transformers, substation reuse reducing cost. Hedged $300M+ at ₹89–93/unit. Net positive bias from hedges.
Merchant market saturation risk — Apoorva Bahadur, IIFL
PartialMarket nascent; only 40% market share (ACME + Adani). Most players targeting PPA, not pure merchant. Peak-demand unmet until last 6 months. 6–7 states now buying BESS. Trust growing state-to-state. No near-term compression seen; duck-curve + solar saturation + EV/AC will drive long-term demand.
Capex execution & debt refinancing — Mohit Kumar, ICICI Securities
PartialINR6,000 Cr arranged for 700 MW FDRE. 85% of PPA-signed tied. Merchant projects opportunistic; no specific merchant debt required upfront. QIP proceeds prepone capex to lock battery costs.
Core renewable EBITDA margin sustainability — Yogesh Patil, Dolat Capital
AnsweredSeasonal 88–92% range guidance. FDRE/peak-power realizations healthier than solar bids. Repowering of existing portfolio drives margin. Will update as new FDRE projects commission.
C&I and data-center strategy — Anuj Upadhyay, Investec
PartialPromising sector; hiring/strategic planning in progress. Will only enter if profitability in high/mid-teen range met. Focus on CTU connectivity for flexibility. SECI platform with data centers emerging; may participate if terms attractive.
Revenue discrepancy check — Implied across multiple Q&A
DodgedNot directly addressed. Call PAT (INR235 Cr) matches delivered (INR235.3 Cr), suggesting same basis. Revenue gap ~INR96.5 Cr (~10%) unexamined; likely preliminary vs final restatement.
Guidance
FY27 contracted renewable ~1.5 GW capacity execution (subject to transmission readiness)
High3,880 MW signed; 1,200 MW balance expected signed soon. Transmission tied-up for 85%. GNA delays on SJVN (June '27) push some projects to FY28.
BESS merchant revenue INR1,400+ Cr partial FY27 (70–80% of 10 GWh capacity locked); full-year upside if 100% contracted
MediumRealizations INR8–10/unit on DEEP/HP-TAM contracts. Pricing subject to seasonal demand, hydro inflow. No volume guidance beyond 10 GWh FY27.
Core renewable EBITDA (ex-BESS) 88–92% seasonal range; FY27 guidance 88–91%
HighDriven by repowering, high CUF. Seasonality: Q1 (91% this quarter) > Q2–Q3. FDRE/peak-power realizations healthier than plain solar bids.
BESS EBITDA margin 80–82% sustained
MediumDependent on power purchase cost for charging, merchandise realizations. Merchant volumes 70–80% locked at INR8–10/unit. Mix tilting to short-term (margin-accretive).
FY27 capex raised to INR15,000–20,000 Cr (from INR15,000 Cr base)
MediumTo front-load BESS and solar capex, capture lower battery costs, prepone GNA timelines. Q1 spent INR3,000 Cr; implies INR12–17k Cr balance 9 months (aggressive cadence).
Risks the call surfaced
Execution & capex leverage
HighFY27 capex ₹15–20k Cr vs delivered ₹857.5 Cr revenue = 1.7–2.3x leverage. GNA delays already pushing some projects to FY28. Transmission readiness contingency built in, but any further slippage compounds capex drag and margin pressure.
Peak-power merchant market depth
HighINR1,400 Cr locked merchant revenue assumes ₹8–10/unit realizations and 10–12 GWh annual capacity available. Market nascent (6 months old); only 6–7 states buying BESS. If hydro inflow rebounds or El Niño effect reverses, demand could soften and realizations compress to ₹6–7/unit, cutting merchant revenue by 25–30%.
Battery cost and supply-chain volatility
MediumLithium carbonate prices volatile. INR93 lakh/MW capex could rise 5–10% above budget if China regulation changes revert, or if dollar strengthens beyond hedged $89–93 rates. 15+ GWh procurement locked at current rates; future orders at risk.
BESS commissioning shortfall
MediumQ1 commissioning target 4 GWh missed; cumulative 3.62 GWh by quarter-end (2.3 GWh Q1 only). If similar slippage continues, FY27 10+ GWh guidance at risk. Supply-chain phasing cited, but compressed timeline (accelerated 3 quarters) leaves limited buffer.
GNA/transmission connectivity delays
MediumSJVN FDRE GNA pushed to June '27 (solar commissioning deferred). Balance 1,200 MW PPA capacity facing similar delays per management. Transmission-readiness contingencies built, but cumulative slippage could defer revenue recognition and extend capex payback cycles.
Management
Score 7/10. Clear on technical specs (89% round-trip efficiency, 93% DoD, 99.9% SoH, 99%+ availability). Detailed on market dynamics (duck curve, BESS merchant depth). Verbosity in Q&A detracts. Did not address revenue discrepancy (₹954 claimed vs ₹857.5 delivered). Beat FY26 capex target (450 MW commissioned). BESS Q1 commissioning missed 4 GWh target (only 3.62 GWh cumulative, 2.3 GWh quarterly). Revenue growth % beat guidance (67.8% vs 63% claimed). PAT tracking stated guidance closely (79.9% vs 80% claimed).
1 · Q2–Q3 FY27
GNA/ISTS connectivity for 1.2 GW balance PPA projects; battery commissioning 3.62→10 GWh
2 · H2 FY27
FDRE bids spike post-recalibration; CFD/state peak-power procurement. 5-year midterm BESS contracts
3 · FY28
SJVN Heergarh/Bikaner II solar GNA; full FDRE capex utilization. Data-center C&I pilot.
However, capex raised to ₹15–20k Cr (2–3x revenue) against backdrop of ₹857.5 Cr actual revenue creates execution and refinancing risk, especially if peak-power merchant spreads compress post-El Niño as GNA delays persist.
