Decree 57 for data centres: DPPA as the Circular 60 reclassification hedge
The short answer — yes, Decree 57 applies to essentially every data centre in Vietnam above hyperscale threshold. But the question that matters in 2026 isn't whether it applies; it's whether you're using it for Scope 2 compliance only, or also to hedge the 49% cost step-up that Circular 60 imposed in February.
Page current as of 23 April 2026. Anchor regulation: Decree 57/2025/NĐ-CP, in force 3 March 2025, materially amended by Resolution 253/2025/QH15 (11 December 2025). Amending implementing decree pending. See the full Decree 57 explainer.
Does Decree 57 apply to my data centre?
Yes — and probably on day one of your site's operating life. Decree 57 sets a 200,000 kWh/month consumption threshold (per Circular 16/2025/TT-BCT) and a ≥22 kV connection requirement. Every hyperscale data centre exceeds both by one to two orders of magnitude; most third-party mid-size facilities exceed them from the first full month of production workload.
The interesting question for a third-party data centre in 2026 is not whether DPPA is available — it is. The interesting question is whether DPPA gets used the way the anchor page frames it (a Scope 2 sourcing tool for hyperscale 100%-RE commitments) or also the way the Circular 62 spoke and the reframed /solutions/data-centres page both point at: an economic hedge against Circular 60/2025's February 2026 reclassification of third-party data centres onto commercial tariff.
Both framings are true. But for a third-party operator watching bills arrive roughly 49% higher than they were in January, the hedge framing is the one that pays for itself before the Scope 2 benefit is even booked.
In practice: every DPPA term sheet a Vietnamese third-party data centre signs in 2026 should be modelled on two benefit streams in parallel — the avoided Scope 2 gap, and the avoided commercial-tariff premium. The relative weight depends on the operator's 2030 RE commitment and the extent of the Circular 60 exposure.
Why DPPA matters more for a third-party data centre in 2026
Three channels through which Decree 57 does more work for a data centre today than the anchor page describes. The anchor handles the regulatory mechanics; this section handles what those mechanics do for a third-party operator navigating the new Circular 60 reality.
4.1 · Tariff hedge against Circular 60 reclassification
Circular 60/2025/TT-BCT, via MOIT's 13 February 2026 guidance letter, moved third-party data centres from the manufacturing tariff (blended ~VND 2,128/kWh at 22 kV) to the commercial tariff (~VND 3,170/kWh at 22 kV) — an increase of roughly VND 1,042/kWh across all hours, or approximately 49%. Viettel, VNPT, FPT Telecom, CMC and VNG jointly petitioned MOIT to reverse it; MOIT declined on 13 February 2026 and reaffirmed the classification.
DPPA electricity priced at the MOIT solar ceiling under Decision 988/QĐ-BCT (approximately VND 1,012–1,382.7/kWh by region, ground-mount) or at a freely negotiated price under Resolution 253/2025/QH15 (typically VND 1,100–1,400/kWh in early 2026 term sheets) is materially below even the off-peak commercial rate, let alone the blended rate. Every kWh delivered under DPPA displaces a kWh that would otherwise have been billed at commercial tariff.
In practice: a DPPA covering 50–60% of a third-party data centre's annual load can neutralise most of the Circular 60 cost increase on that contracted portion. The balance of load — intermittency shortfall, transmission losses, and the grid-connected portion subject to CDPPA — continues to pay commercial retail tariff. Hedge, not elimination.
4.2 · Captive vs third-party divergence under Circular 60
Circular 60's Clause 19, Article 11 read with PM Decision 36/2025/QĐ-TTg creates three treatments: third-party (colocation, hyperscale) data centres on commercial tariff; captive (internal-use) data centres remaining on manufacturing tariff; mixed-use facilities allocated pro-rata. The DPPA hedge case is strongest where the commercial-tariff exposure is 100% — pure colocation or hyperscale operators selling compute capacity to external customers.
A captive data centre — one serving only a single parent operator, where all compute supports internal production or administrative load — remains on manufacturing tariff. Its blended cost is ~VND 2,128/kWh. DPPA still delivers Scope 2 value and modest energy savings, but the dramatic ~49% cost delta that justifies the effort for third-party operators does not exist. A mixed-use operator must assess what proportion of its 24/7 load is external-facing versus captive, apply the relevant tariff pro-rata, and weight the DPPA case accordingly.
In practice: the first question a data-centre operator should answer before modelling a DPPA in 2026 is the Circular 60 classification status — not the Decree 57 eligibility, which is essentially always yes. Classification determines hedge magnitude. Third-party operators get the full story; captive operators get Scope 2 only; mixed-use operators get some fraction in between.
4.3 · Resolution 253 opens the pricing ceiling
National Assembly Resolution 253/2025/QH15 (11 December 2025) removed the MOIT ceiling-price constraint on private DPPA and grid-connected DPPA forward contracts — prices are now "negotiated and agreed freely" between seller and buyer. The amending implementing decree that specifies how this operates in practice is pending, expected to issue from March 2026 under simplified procedures per the Resolution's directive.
For a data centre operator, Resolution 253 changes the negotiation posture. Before December 2025, DPPA strike prices had to stay at or below the Decision 988 ceiling. After Resolution 253, the ceiling is informational rather than binding — the market is free to transact above or below it. In early 2026 term sheets, developers with strong sites and bankable offtake credit are negotiating slightly above the Decision 988 level where buyer credit supports it, while data-centre offtakers with 100%-RE commitments use their credit profile to push toward or below the ceiling.
In practice: a 2026 DPPA term sheet should reference both Decision 988's ceiling tariffs as a market-anchor point and Resolution 253's free-negotiation provision as the operative pricing basis. Include a change-in-law clause covering the pending amending implementing decree — it may specify price-notification procedures, cap-ordering rules, or free-negotiation methodology that affects what was thought to be bilaterally agreed.
Decree 57 terms most relevant to a data-centre operator
The anchor page covers the full Decree 57 framework. What follows is the narrow slice a data-centre operator actually uses in term-sheet negotiation.
- 200,000 kWh/month threshold (Circular 16/2025/TT-BCT) Applies to all data centres, trivially met. A 30 MW site consumes ~22 GWh/month — 110× the floor. For data-centre context the threshold is a historical curiosity rather than a live constraint; relevant only for mid-size captive facilities below ~2 MW IT load.
- Model 1 (private wire) vs Model 2 (grid-connected) Model 1 is cleanest economically — direct physical line from generator to consumer, no CDPPA wheeling charge. Rare for hyperscale data centres sited in urban or industrial-park clusters away from RE generation. Model 2 is the dominant pathway; it adds the CDPPA charge (see below), which can erode the hedge value by 20–40% depending on the annual CDPPA level.
- CDPPA wheeling charge (Model 2 only) Set annually by MOIT, no statutory cap on year-on-year increases. Covers transmission, distribution, retail, system operation, market transaction, and sector administration costs. An industry request to cap annual increases at ≤3% has not been adopted. For data-centre modelling, CDPPA is the single biggest residual-exposure variable in a Model 2 DPPA — treat it as a live assumption that requires annual re-baselining, not a fixed input.
- Resolution 253/2025 free-price negotiation Removes the Decision 988 MOIT ceiling as a binding cap. Operative since 11 December 2025; implementing decree pending expected from March 2026 onwards. Until the decree issues, term sheets should reference both the old ceiling and the new freely-negotiated basis, with change-in-law protection covering the interim.
- Two-part tariff double-charging risk (pending) Capacity charge under the two-part tariff (parallel shadow billing since 1 January 2026 for manufacturing ≥200,000 kWh/month; real-money billing from 1 July 2026) recovers grid-infrastructure costs already partly captured in CDPPA. Commercial-tariff rollout expected 2028–2030 per EVN's published plan. Not yet a direct exposure for data centres on commercial tariff but a known pending issue — see Decree 146/2025/NĐ-CP explainer.
Worked example — a 30 MW hyperscale data centre assessing DPPA as Circular 60 hedge
A third-party hyperscale data centre in Long An, 22 kV commercial tariff, 30 MW IT load
Setup
- IT load30 MW hyperscale data centre, Long An province (South)
- Annual consumption~263 GWh (30 MW × 8,760 hours × ~95% utilisation)
- Voltage22 kV connection
- Tariff classificationThird-party commercial (kinh doanh) per Circular 60/2025
- Corporate commitment100% renewable electricity by 2030 (hyperscale industry baseline)
- DPPA target60% of annual load contracted under Model 2 grid-connected DPPA with solar+wind portfolio
Hedge math — annual cost comparison
| Cost component | Volume | Unit rate | Annual cost |
|---|---|---|---|
| Scenario A — no DPPA (100% commercial retail) | 263 GWh | VND 3,170/kWh | VND 834 bn |
| Counterfactual — on old manufacturing tariff | 263 GWh | VND 2,128/kWh | VND 560 bn |
| Circular 60 reclassification cost, no hedge | — | VND 1,042/kWh | VND 274 bn |
| Cost component | Volume | Unit rate | Annual cost |
|---|---|---|---|
| Scenario B — 60% DPPA + 40% commercial retail | — | — | — |
| DPPA portion (solar+wind, negotiated per Resolution 253) | 158 GWh (60%) | VND 1,200/kWh | VND 189 bn |
| CDPPA wheeling charge on DPPA portion (estimate) | 158 GWh | VND 450/kWh | VND 71 bn |
| Commercial retail on balance + intermittency shortfall | 105 GWh (40%) | VND 3,170/kWh | VND 333 bn |
| Total Scenario B | 263 GWh | — | VND 594 bn |
Interpretation
Scenario B delivers an annual cost saving of approximately VND 240 billion (≈ US$9.5M) relative to Scenario A. That offsets roughly 88% of the Circular 60 reclassification cost while also delivering the Scope 2 benefit of 158 GWh/year of contracted renewable electricity — approximately 107,000 tCO₂e avoided at Vietnam's 2024 grid emission factor of 0.681 tCO₂e/MWh.
The CDPPA estimate of VND 450/kWh is the single most uncertain line in this model; actual CDPPA for 2026 has not been published as of April 2026 and the figure used here is a midpoint of industry working estimates. A CDPPA outcome at VND 600/kWh would compress the hedge saving to approximately VND 216 billion; at VND 300/kWh it would expand to approximately VND 264 billion.
In practice: the DPPA hedge almost fully offsets the Circular 60 cost increase on the contracted portion, but does not eliminate it because (a) CDPPA recovers some of the cost EVN otherwise collected through retail tariff, and (b) the ~40% balance of load continues to pay commercial retail. The hedge scales with DPPA contracted share — moving from 60% to 80% contracted coverage further reduces retail-tariff exposure but increases intermittency-shortfall risk that the DPPA generator may not firm.

Three DPPA pathways for a third-party data centre, ranked
Which of Decree 57's mechanisms gives a third-party data centre the cleanest economic and Scope 2 outcome. The right answer depends on site infrastructure, not the regulation.
- Decree 58 rooftop + Model 2 DPPA for the balance Where site roof or adjacent land permits, self-consumption solar under Decree 58/2025/NĐ-CP handles the daytime portion of load at near-zero marginal cost (no CDPPA, no DPPA contract term). A Model 2 DPPA covers the balance and the evening peak. This hybrid minimises CDPPA exposure by shrinking the DPPA contracted volume to only what the roof cannot cover, while still hitting the 100%-RE commitment through combined volume. The practical constraint is space — a 30 MW hyperscale site with 2 MWp of rooftop capacity covers only ~2–3% of load from rooftop; a mid-size 5 MW site with 3 MWp of rooftop covers 10–15%. Pair with BESS under retail-tariff arbitrage for completeness. Preferred where site permits
- Model 2 grid-connected DPPA, standalone Dominant pathway for hyperscale sites without adjacent RE generation. Contracts directly with a solar, wind, or solar+BESS project, typically via an aggregator or generator operator. The CDPPA charge is the defining economic variable — expect it to consume 20–40% of the nominal DPPA saving, and expect the annual CDPPA resetting to be volatile. Structure for change-in-law protection on CDPPA escalation; some 2026 term sheets include CDPPA-linked strike-price adjustments to share the risk between generator and offtaker. Scope 2 clean. Dominant for most hyperscale
- Model 1 private wire DPPA Cleanest economics — no CDPPA, full delivered price captured. Requires the data centre site to be physically adjacent to (or co-located with) renewable generation, typically a utility-scale solar or wind farm with capacity allocation reserved for the offtaker. For most Vietnamese data centres sited near load centres rather than near generation, Model 1 is infrastructure-gated, not regulation-gated. Where it works — typically through an industrial park developer with on-site generation, as in the LEGO-VSIP Binh Duong precedent — it delivers the lowest total DPPA cost. Gated on site adjacency
In practice: start with pathway 1 if roof or land permits; default to pathway 2 if not; pursue pathway 3 only if an industrial-park developer or site-adjacent generator offers it. Do not spend negotiating time pursuing Model 1 at a site where it is infrastructure-impossible — the search cost rarely recovers.
Frequently asked questions
Does Decree 57 apply to data centres in Vietnam?
Yes. Every hyperscale and most mid-size third-party data centres exceed Decree 57's 200,000 kWh/month threshold (set by Circular 16/2025/TT-BCT) by one to two orders of magnitude. A 30 MW hyperscale site consumes roughly 22 GWh per month — 110 times the threshold. Eligibility is essentially automatic; the live question is which of the three DPPA pathways to structure.
Why does DPPA matter more for a third-party data centre after Circular 60/2025?
Circular 60/2025/TT-BCT reclassified third-party data centres from manufacturing tariff to commercial (kinh doanh) tariff in February 2026 — roughly a 49% increase in blended electricity cost. DPPA electricity priced against the MOIT solar ceiling (approximately VND 1,012/kWh ground-mount South) or negotiated freely under Resolution 253/2025 is materially below the ~VND 3,170/kWh blended commercial tariff. A DPPA covering 60% of annual load at VND 1,200/kWh can offset most of the Circular 60 cost increase, while also delivering the Scope 2 benefit.
Can a data centre use DPPA to avoid the Circular 60 commercial-tariff classification?
No. DPPA does not change the classification itself — third-party data centres remain on commercial tariff. DPPA hedges the economic impact by shifting a portion of total consumption onto a DPPA-priced contract, reducing the volume of kWh billed at commercial retail rates. The remaining grid-consumed portion still pays commercial tariff. A captive (internal-use-only) data centre remains on manufacturing tariff under Circular 60 and therefore has less hedge headroom from DPPA.
Which DPPA pathway makes most sense for a third-party data centre?
Three configurations apply. Model 1 private wire is cleanest economically (no CDPPA wheeling charge) but requires the data centre site to be physically adjacent to RE generation — rare for hyperscale sites in Ho Chi Minh City or Hanoi clusters. Model 2 grid-connected is the dominant pathway but adds the CDPPA grid service charge, which can erode the hedge. A hybrid — on-site rooftop or ground-mount solar under Decree 58 self-consumption, layered with a Model 2 DPPA for the balance — is often the most economically efficient structure where space permits.
How does the two-part tariff interact with DPPA for data centres?
A known double-charging risk. Capacity charges under the two-part tariff (Decree 146/2025/NĐ-CP, real-money billing from 1 July 2026 for manufacturing ≥200,000 kWh/month) recover grid-infrastructure costs; CDPPA under Decree 57 also recovers grid-infrastructure costs. Norton Rose Fulbright confirmed in January 2026 that DPPA offtakers will likely still pay the full capacity charge. Commercial-tariff rollout of the two-part tariff is not expected before 2028, but any DPPA term sheet signed in 2026 should include change-in-law protection for when it arrives.
