How does the new EVN Decision No. 963/QD-BCT impact steel furnace operations?

Decision 963 has shifted peak hours to 5:30 PM – 10:30 PM daily (except Sundays). This 5-hour window is critical because electricity rates are up to 3.3x higher than off-peak. T80-optimized furnaces use AI to 'pre-heat' billets during normal hours and maintain thermal mass during peak windows, shifting 15-30% of energy load to cheaper periods.

What is the 'Two-Part' electricity tariff being trialed by EVN in 2026?

EVN is piloting a capacity-based charge in addition to energy consumption. This means mills will be charged for their peak power demand. T80 optimization reduces peak furnace load through AI-driven burner sequencing, preventing expensive capacity surcharges.

Is the current EU carbon price of €77.24 sustainable for Vietnamese exporters?

With carbon prices trending toward €82/ton, an unoptimized mill with high fuel intensity faces an 'efficiency tax' that can wipe out all export profit. The T80 Roadmap is designed to lower carbon intensity by 10-15%, making EU export orders financially viable again.

2026 Summer Energy Crisis Survival Guide: The T80 Technical Roadmap for Vietnam Steel

Today, May 12, 2026, Vietnam is entering a critical dry season. With energy demand forecasted to grow by 8.5% to 14.1% this summer, the Ministry of Industry and Trade (MoIT) has just implemented Decision No. 963/QD-BCT, fundamentally restructuring electricity peak hours. For steel mill owners in the Binh Duong, Long An, and Hai Phong clusters, this isn't just about the heat—it’s about the 3.3x price gap between peak and off-peak hours and the looming shadow of the €77.24/ton EU carbon price.

The T80 Technical Roadmap, developed by EcoReheating (South Technology), is no longer a long-term goal; it is a summer survival manual. This 3,500-word guide details how to leverage extreme efficiency to navigate the 2026 summer crisis and secure your export competitiveness.

1. The 2026 Summer Reality: Decision 963 & Peak-Hour Shifts

The implementation of Decision 963 has moved the industrial peak-hour window to 5:30 PM – 10:30 PM. For a reheating furnace, which typically accounts for 60% of a plant's energy load, this shift is critical.

Period	Time Window (Decision 963)	Cost Multiplier	Strategy
Off-Peak	0:00 AM – 6:00 AM	1.0x (Base)	High-throughput charging
Normal	6:00 AM – 5:30 PM	2.2x	Steady-state rolling
Peak	5:30 PM – 10:30 PM	3.3x	AI-Driven Load Shifting

Under the T80 Standard, our AI systems predict rolling mill requirements 4 hours in advance. By "over-charging" thermal energy into the furnace during normal hours and dropping to a minimum-maintenance state during the 5:30 PM peak window, mills can avoid the highest electricity tariffs without stopping production.

2. Technical Module: AI Predictive Stoichiometry for Fuel Flexibility

The 2026 Challenge: Gas Pressure Fluctuations

As industrial parks prioritize power generation during the heatwave, gas supply pressure to steel mills often fluctuates. Traditional manual controls cannot react fast enough, leading to "rich" combustion (fuel waste) or "lean" combustion (billet oxidation).

The T80 Solution: Real-Time Stoichiometric Correction

The T80 roadmap integrates real-time flow meters and oxygen analyzers that communicate with our AI Command Center. Even if gas pressure drops by 15%, the AI adjusts the air-fuel ratio within 3 seconds to maintain the stoichiometric "sweet spot."

Carbon Impact (May 2026 Data): With the EU carbon price currently at €77.24, every cubic meter of wasted gas carries a financial penalty. An optimized T80 furnace reduces CO2 intensity from 120kg/t down to 102kg/t, saving an estimated €1.39 in carbon certificates per ton of steel exported to the EU.

3. Technical Module: High-Emissivity "Cold-Wall" Technology

The Problem: Summer Shell Radiation

When ambient temperatures reach 40°C in Binh Duong, the heat radiating from a traditional furnace shell (often 120°C+) creates an unbearable working environment and wastes massive energy.

The T80 Solution: Multi-Layer Fiber & Functional Coating

We replace heavy castables with multi-layer ceramic fiber modules and apply a high-emissivity functional coating to the interior. This "Cold-Wall" approach keeps the furnace shell below 70°C even during the summer peak. This doesn't just save 5% in fuel; it protects your workforce and prevents thermal-induced equipment failure during the high-demand season.

2026 Policy Alert

Two-Part Electricity Tariff Pilot

EVN is currently trialing a 'Capacity Charge' for large industrial customers. This means you will be billed not just for the energy you use, but for your peak power demand (kW). T80 AI systems prevent power spikes during furnace startups, potentially saving thousands in capacity surcharges during the pilot phase.

📋 Vietnam Steel Q1 2026 Performance Despite the crisis, Vietnam exported 2.94 million tonnes of steel in Q1 (+7% YoY). However, the US market (+32% YoY) and the EU are increasingly demanding "Green Steel" documentation. Download Q1 Compliance Report → | View T80 Case Studies →

4. Yield Improvement: Turning Scale into Cash Flow

In the current market, steel prices are volatile. Reducing "Scale Loss" (surface oxidation) from 1.0% to 0.6% adds 2,000 tons of saleable steel to a 500,000 tpy mill. This yield gain is the fastest way to fund your energy efficiency upgrades. Under our Zero CAPEX Energy Steward model, we use these verified savings to pay for the T80 hardware, meaning you get the technology for $0 upfront.

Conclusion: The Roadmap to August

The T80 Technical Roadmap is the bridge to August, when the summer peak subsides and the Q4 production surge begins. For mill owners, the choice is clear: adapt to the Decision 963 reality today, or face uncompetitive energy bills by the end of the dry season.
