Vietnam's Two-Part Electricity Pricing and DPPA Evolution
Vietnam is transitioning to a two-part electricity price mechanism, separating capacity and energy charges, alongside developing Direct Power Purchase Agreements (DPPA). This aims for a transparent market, encouraging investment and reflecting true costs. However, this shift introduces financial complexities for DPPA, potentially reducing its attractiveness and impacting renewable energy project viability for stakeholders.
Key Takeaways

DPPA's financial benefits are significantly reduced by this change.
Renewable energy investors face increased financial risks.
Consumers must adapt to new billing and potential cost shifts.
Strategic solutions like BESS are crucial for future energy efficiency.
What is the context and structure of Vietnam's evolving electricity pricing?
Vietnam's energy sector is transforming due to global energy transition, national energy security needs, and sustainable renewable energy development. This aims to create a transparent electricity market, encourage long-term investment, and ensure prices reflect actual costs. The proposed mechanism introduces a two-part structure to achieve these objectives, separating charges for infrastructure readiness and actual consumption.
- Context: Energy transition, ensuring energy security, and sustainable renewable energy development.
- Objectives: Transparent electricity market, encouraging long-term investment, and reflecting true costs.
- Mechanism Structure: Capacity Charge (fixed payment for power supply capability); Energy Charge (variable payment for actual electricity consumption).
How are the two-part pricing mechanism and DPPA evolving in Vietnam?
Vietnam is implementing a two-part electricity price mechanism, distinguishing capacity and energy components, while developing Direct Power Purchase Agreements (DPPA). Two-part pricing aims to better allocate costs, covering infrastructure with capacity charges and actual usage with energy charges. Grid-connected DPPA allows businesses to directly purchase renewable energy via EVN's grid for financial netting. However, current grid-connected DPPA models primarily involve financial exchanges, not physical peak load reduction.
- Two-Part Price Mechanism: Comprises a capacity charge (kW/MW) and an energy charge (kWh/MWh).
- Grid-Connected DPPA Mechanism: Businesses directly buy from renewable energy sources, using EVN's grid for transmission, with financial settlement.
- Limitations of Grid-Connected DPPA: Does not physically reduce peak load and primarily involves financial contract exchanges.
What financial conflicts arise for DPPA under a two-part pricing system?
The shift to a two-part electricity pricing mechanism creates significant financial conflicts for Direct Power Purchase Agreements (DPPA). Currently, single-part pricing based on energy (kWh) allows DPPA to offer direct offsets, reducing overall electricity costs. However, under a two-part system, businesses still pay EVN's capacity charge. DPPA will only offset the energy charge component, leaving capacity charges unaffected. This substantially diminishes DPPA's economic efficiency, especially if EVN's energy prices are lower.
- Current (Single-Part Price): Electricity priced by volume (kWh); DPPA directly reduces total electricity costs.
- Transition to Two-Part Price: Businesses continue paying EVN's capacity charge.
- DPPA only offsets the energy charge component.
- No reduction in capacity charges.
- DPPA's economic efficiency significantly decreases.
- EVN's energy prices may be lower, impacting DPPA competitiveness.
What are the specific impacts of these changes on key stakeholders?
The evolving pricing and DPPA framework will profoundly affect various stakeholders in Vietnam's energy sector. Solar power investors face lower competitive DPPA selling prices, reduced revenue, and difficulties securing financing, potentially increasing equity requirements or lowering internal rates of return, especially for solar farms. Wind power projects, despite their capacity contribution, may not directly receive capacity payments through DPPA, leading to pressure on energy prices. Electricity consumers (offtakers) will see a substantial reduction (30-50%) in DPPA savings, as they still bear the full capacity charge, making DPPA less attractive without load adjustment or storage. The national power system (EVN) faces challenges in maintaining infrastructure and reserve capacity, reduced energy revenue, and increased operational and investment cost pressures, raising questions about future capacity charge collection and overall tariff structure.
- Solar Power Investors: Lower DPPA selling prices, reduced revenue, financing difficulties, increased equity, and higher revenue risk for solar farms.
- Wind Power Projects: Advantage in capacity profile, but DPPA does not directly pay for capacity, leading to pressure on energy prices.
- Electricity Consumers (Offtakers): Reduced DPPA savings (30-50%), still pay full capacity charge; DPPA less attractive without load management or storage.
- National Power System (EVN): Maintains infrastructure and reserve capacity, reduced energy revenue, increased operational/investment costs, and questions on future tariffs.
What are the overall market impacts of these changes?
The transition to a two-part electricity pricing mechanism and its interaction with DPPA will have broad market implications. The financial efficiency of DPPA, previously high under a single-part tariff, will significantly decrease. This reduced attractiveness will lead businesses to explore alternative direct power sources like Battery Energy Storage Systems (BESS), rooftop solar, or energy efficiency measures. Consequently, financing for new renewable energy projects will diminish. While the previous single-part system encouraged rapid renewable energy growth but posed grid risks, the new two-part system might slow new investment but could aid grid balancing by better reflecting capacity costs.
- DPPA Financial Efficiency: High before two-part pricing, significantly lower afterward.
- DPPA Attractiveness for Businesses: Reduced, prompting businesses to seek direct power sources (BESS, rooftop, efficiency).
- Renewable Energy Project Financing: Strong before, reduced after the transition.
- Impact on Power System: Previously rapid RE growth with grid risks; now, slower investment but better grid balancing support.
What issues arise, and what solutions are proposed for stakeholders?
The shift presents critical issues for both power source investors and customers, necessitating strategic solutions. Investors face limited capacity charge benefits, low DPPA energy prices, increased cash flow risks, and unclear capacity contribution standards. Customers struggle with no actual peak load reduction and diminished DPPA financial benefits, compounded by potentially decreasing EVN energy prices and uncertain future capacity charges. Addressing these requires tailored approaches for different energy models and clear policy frameworks.
- For Power Source Investors:
- Issues: Limited capacity charge benefits, low DPPA energy prices, higher cash flow risk, and unclear capacity contribution standards.
- Rooftop Solar Solutions: Integrate Solar, BESS, and operational optimization for peak load reduction; BESS is key, though quantifying capacity cost reduction is complex.
- Large-Scale Power Solutions: Grid-connected DPPA offers no peak load reduction; customers gain no capacity cost savings; requires competitive energy selling prices.
- Policy Recommendations: Two-part pricing expected July 1, 2026; large-scale RE should prioritize selling to EVN under ceiling prices; DPPA as a secondary option.
- Price Structure: Includes capacity charge (VND/kW/month), energy charge (VND/kWh), and 26-38% overall reduction.
- For Customers:
- Key Issues: No actual peak load reduction, reduced DPPA financial benefits, declining EVN energy prices, and uncertain future capacity charges.
- Proposed Solutions:
- Rooftop Solar Model: Integrate Solar + BESS + energy saving; conduct thorough load surveys; advocate for PPA mechanism re-evaluation.
- Large-Scale Projects: Requires clear capacity policy and prioritizing direct sales to EVN.
- EVN Electricity Bill Analysis: Analyze two-part bills to understand calculations, cost allocation, and DPPA interaction.
Frequently Asked Questions
What is the core difference between the old and new electricity pricing mechanisms?
The old mechanism had a single price based on energy consumed. The new two-part system separates this into a fixed capacity charge and a variable energy charge, aiming to reflect infrastructure costs and actual usage more accurately.
How does the two-part pricing impact the financial benefits of DPPA for businesses?
Under two-part pricing, DPPA only offsets the energy charge, not the capacity charge. This significantly reduces the overall financial savings for businesses, making DPPA less attractive compared to the previous single-part system.
What solutions are proposed for customers to mitigate the impact of these changes?
Customers should consider integrating rooftop solar with Battery Energy Storage Systems (BESS) and energy saving measures. Comprehensive load surveys and advocating for revised PPA mechanisms are also crucial for optimizing energy costs.
