Adani Green Targets 10 GWh BESS by FY27

Adani Green Energy Limited — Q4 FY26 Earnings (Equity Conference Call, Apr 24, 2026)

1. Overall Tone of Management: Optimistic

• Management highlights “robust operational and financial performance,” “unparalleled execution capabilities,” and “very comfortable” confidence in battery ramp.
• Even when discussing risks (curtailment/evacuation), they frame them as manageable via storage: “batteries… is a hedge” and “don’t expect… any significant evacuation constraints.”

2. Key Themes from Management Commentary

• Scale-up and execution momentum (FY26):
• Energy sales +34% YoY to 37.6 bn units; revenue from power supply +22% to INR 11,602 cr; EBITDA +23% to INR 10,865 cr; EBITDA margin 91.2%.
• Added 5.1 GW in FY26 (+35% YoY) and claims 19.3 GW operating portfolio.
• Khavda as the core growth engine + storage integration:
• Khavda progress: 9.4 GW operational; battery added 1.4 GWh in the last year.
• Management repeatedly links improved evacuation/merchant outcomes to Khavda transmission lines coming online.
• Battery Storage (BESS) as strategic “hedge” and economics lever:
• Batteries described as “delinked with pretty much everything else” and hedging grid/transmission curtailment.
• Targeting 10 GWh+ battery additions in FY27 (and discussing 2–3 hour configurations).
• Contracting strategy: long-term PPAs remain the structural goal
• “More than 90%” of added capacity to be tied to long-term contracts.
• Explains FY26 merchant/infirm mix as an anomaly driven by ISTS benefit timing and interim periods.
• Evacuation/transmission constraints acknowledged but actively managed
• They explicitly reduce solar/wind execution to 4.5–5 GW due to expected evacuation constraints, while accelerating batteries to mitigate risk.
• C&I/data center demand routed via group entity
• C&I/data center contracting handled by Adani Energy Solutions (AESL); AGEL contracts capacity to AESL at market-linked rates.

3. Q&A Analysis

Theme A: BESS ramp milestones, dependencies, and operational readiness

• Core questions
• How to ramp BESS from current levels to ~10 GWh by FY27: milestones, supply chain/grid connectivity, and preparedness.
• Battery economics vs solar/wind (margin, capex, payback).
• Management response
• Near-term milestone: “reach the mark of 3 gigawatt hours of installed capacity in Khavda… in the next week.”
• Ramp confidence: “run rate quarterly of about 3 gigawatt hours” and “comfortable” to maintain/increase.
• Key sensitivities: “capital flexibility” and “organizational capability to manage the supply chain.”
• Economics: funding assumption ~INR 1.5 cr/MWh and “~INR 25 lakhs of EBITDA per megawatt hour” (thumb rule). Also claims batteries are “similar to or… slightly better” than renewables.
• Curtailment angle: batteries convert “wasted power” into economic value; margins can improve if curtailment persists.
• Notable/strong or evasive elements
• Strong confidence language (“very comfortable,” “only 2 sensitivities”).
• Economics are provided as thumb rules; no detailed sensitivity to cycles, tariffs, or degradation.

Theme B: Curtailment impact, merchant/infirm conversion, and evacuation timing

• Core questions
• EBITDA loss due to curtailment vs long-term PPA economics; expected impact going forward.
• Whether infirm/merchant power will convert to long-term PPAs as transmission improves.
• Management response
• Curtailment losses: “lost about INR 500 crores of EBITDA” in FY26 due to curtailment; total loss estimate INR 1,300–1,500 cr (including merchant vs realization gap).
• Forward view: “do not expect… going forward” the same losses.
• Execution gating: they will stop solar/wind execution at 4.5–5 GW due to evacuation constraints to avoid “capacities coming up and then evacuation not being sufficiently available.”
• Conversion commitment: stated goal that >90% of new capacity tied to long-term contracts; “last year was an anomaly” due to ISTS benefit timing.
• Infirm conversion timing: incrementally by Dec 2026, with some by Mar 2027.
• Notable/strong or evasive elements
• “Worst is behind” was not fully conceded; they responded with caution: curtailment may still occur in pockets (“I don’t think that one… can say that this issue is permanently behind us”).
• They provide specific conversion windows (Dec 2026 / Mar 2027), which increases credibility vs vague guidance.

Theme C: Growth plans, contracting pipeline, and C&I/data center strategy

• Core questions
• Beyond recent PPA tenders, will AGEL focus on C&I/data centers via AESL?
• Clarify commercial terms of AESL arrangement.
• How much capacity is already signed (PPA visibility).
• Management response
• Signed PPA capacity: “total of 28 gigawatts already signed up.”
• Directional shift: DISCOM contract nature changing; C&I/data center demand expected at AESL; AGEL remains focused on >90% long-term contracted capacity.
• AESL terms: “arm’s length market test basis” with independent market discovery; rates cited solar INR 2.60–2.80 and wind INR 3.70–3.80 (may move with market).
• Notable/strong or evasive elements
• Clear structural explanation of group roles (AGEL generation contracting; AESL customer interface).
• No discussion of margin split between AGEL and AESL beyond rate ranges.

Theme D: Capex, blended cost of capital/rating impact, and execution capacity

• Core questions
• Capex implications of 5–6 GW RE + 10 GWh BESS.
• Whether blended rate (8.9% mentioned) will improve with rating upgrade.
• Evacuation capacity additions at Khavda (quantification for FY27/FY28).
• Management response
• Capex: guided “INR 40,000 to 42,000 crore” generally; acknowledged could “touch” ~INR 45,000 cr depending on execution.
• Rating: “expect downward pressure” on blended rate.
• Evacuation: Khavda transmission opening +7 GW by Dec 2026 and +7 GW by Mar 2027; total 14–15 GW over next 12–15 months (± 3–4 months).
• Notable/strong or evasive elements
• Evacuation numbers include explicit “margin of error,” which is prudent.
• Capex guidance is broad; no breakdown between RE vs BESS.

4. Guidance / Outlook

Explicit guidance (quantitative)

• FY27 RE execution: “4.5 to 5 gigawatts” (stopping execution level due to evacuation constraints).
• FY27 BESS commissioning/addition: “north of 10 gigawatt hours” by end of the year.
• Battery configuration: “3-hour configuration” (flexible 2–3 hours).
• Capex for batteries: “~INR 1.5 crores per megawatt hour” → “~INR 15,000 crores total capex” (for batteries).
• Khavda evacuation/transmission additions:
• “additional 7 gigawatts… by December of 2026”
• “additional 7 gigawatts… by March of ’27”
• Current active Khavda transmission: “9 gigawatts”
• Infirm → PPA conversion timing: “incrementally happen by December of 2026… some… by March 2027.”
• Capex (company-level): “INR 40,000 to 42,000 crore” (general guidance); could “touch” ~INR 45,000 cr.
• Blended rate: “expect downward pressure” (qualitative, but tied to rating improvement).

Implicit signals (qualitative)

• Curtailment risk mitigation: batteries are positioned as a structural hedge against grid/transmission curtailment.
• Merchant/infirm losses viewed as non-recurring: management expects curtailment/merchant realization gaps to normalize (“do not expect… going forward”).
• FY28 ramp depends on evacuation: they avoid hard FY28 numbers; will guide later, contingent on transmission opening.

5. Standout Statements (direct / high-signal)

• BESS as hedge: “batteries operate as a hedge to the lack of grid availability.”
• Only key sensitivities for BESS ramp: “capital flexibility… and… organizational capability to manage the supply chain.”
• Battery economics claim: “we should be able to get about INR 25 lakhs of EBITDA per megawatt hour.”
• Curtailment losses quantified: “lost about INR 500 crores of EBITDA… on account of curtailment.”
• Non-recurring framing: “we do not expect to be happening going forward” (re: INR 1,300–1,500 cr EBITDA loss range).
• Evacuation-driven execution discipline: “We are stopping our execution… at between 4.5 to 5 gigawatts… to avoid… evacuation not being sufficiently available.”
• Evacuation uncertainty acknowledged: “I don’t think that one… can say that this issue is permanently behind us.”
• Long-term contracting anchor: “more than 90% of installed capacity… tied up in long-term contracts.”

6. Red Flags / Positive Signals

Red flags
– High-margin narrative vs complexity: EBITDA margin 91.2% is extremely high; while not disputed, it increases the need for scrutiny of accounting/segment mix (no reconciliation in transcript).
– Economics are “thumb rule” based: battery EBITDA per MWh is not shown with scenario ranges (tariff, cycles, curtailment assumptions).
– “Do not expect” language on curtailment losses is strong; they also admit curtailment can persist in pockets—potential tension.

Positive signals
– Specific operational milestones (3 GWh Khavda in a week; 10 GWh by FY27 end; conversion by Dec 2026/Mar 2027).
– Clear execution gating logic (reduce RE execution until evacuation capacity is ready).
– Group contracting clarity (AESL arm’s-length market test; AGEL role separation).

7. Historical Comparison & Consistency Analysis (vs prior calls)

Note: Prior transcript provided is Q4 & FY25 (Apr 29, 2025). No additional FY24/FY26 prior calls were included beyond that single prior document.

a. Change in Tone Over Time

• Current (FY26 call): More Optimistic, with stronger confidence on BESS ramp and “hedge” framing.
• Prior (FY25 call): Optimistic but more execution/learning-focused; emphasized CUF stabilization and environmental learnings, and was more cautious on policy items (e.g., ISTS waiver extension watched closely).
• Shift classification: More Optimistic
• Current call uses “very comfortable,” “comfortable that we will continue,” and provides more quantified milestones for BESS and evacuation.

b. Tracking Past Commitments vs Outcomes

• Past statement (FY25 call): Target to add 5 GW in FY26 (“We are targeting to add 5 gigawatts in this financial year too.”)
• What happened / current call evidence: FY26 execution guidance/actual is framed as 5.1 GW added in FY26 (“added 5.1 gigawatts”).

• Assessment: ✅ Delivered (very close to target; current call indicates 5.1 GW added).

• Past statement (FY25 call): Transmission concerns to be managed; expectation of evacuation additions (June/Dec) and ISTS waiver risk managed by strategy.

• Current call: They explicitly quantify evacuation additions and tie BESS ramp to transmission constraints; also quantify curtailment losses and conversion timing.
• Assessment: ✅ Improved specificity; not a direct “commitment check,” but indicates execution of the strategy.

c. Narrative Shifts

• Merchant/ISTS narrative becomes more “structural anomaly”
• FY25: merchant strategy discussed with ISTS waiver ending June 2025; more discussion on merchant price uncertainty.
• FY26: merchant/infirm mix is explicitly called an “anomaly” due to ISTS benefit going away, and they emphasize return to >90% long-term contracted additions.
• BESS moves from “watch closely” to “core hedge + quantified capex/run-rate”
• FY25: battery merchant arbitrage mentioned as “keeping our close watch… you will be one of the first ones to hear**.”
• FY26: battery is now central with 10 GWh target, economics, and operational milestones.

d. Consistency & Credibility Signals

• Credibility improved on operational quantification: FY26 call provides more concrete numbers (BESS run rate, conversion dates, evacuation GW).
• Risk communication is mixed: they both say losses won’t recur and also admit curtailment may persist in pockets—this is not necessarily inconsistent, but it shows a need to reconcile “non-recurring” vs “pockets of uncertainty.”

Overall credibility (based on communication consistency): Medium to High
– Stronger quantification and clearer gating logic than FY25.
– Still relies on “expect/do not expect” language without full sensitivity disclosure.

e. Evolution of Key Themes

• Demand/macro: FY26 leans into “energy security/electrification” tailwind; FY25 focused more on execution and CUF stabilization.
• Margins: FY26 emphasizes EBITDA margin and battery economics; FY25 emphasized EBITDA growth and CUF.
• Evacuation risk: FY25 discussed transmission tracking and ISTS; FY26 quantifies evacuation additions and explicitly limits RE execution until evacuation is ready.
• Contracting: Both calls emphasize PPAs, but FY26 is more explicit about >90% long-term and interim infirm conversion mechanics.

f. Additional Insights (cross-period intelligence)

• Curtailment is being reframed as “manageable via storage,” not eliminated. This suggests the company expects transmission bottlenecks to remain a recurring sector issue, but believes BESS can neutralize the financial impact.
• Battery capacity is being used as both operational insurance and commercial optionality (“available for all 3 purposes”), implying management is prioritizing flexibility over locking a single revenue model.
