Latest Energy Technology Standards

Central Electricity Authority (Cea) 2026 Amendment Sets New Technical Standards for #BESS, #Solar, and #Wind Projects in India effective from 1st April 2027. For years, BESS were largely seen as energy buffers. This amendment changes that narrative completely. Now, every BESS is expected to behave like a grid participant, not just a storage unit. • Active & reactive power control • Voltage regulation at the point of interconnection • Frequency response support This effectively aligns BESS with the expectations of modern #gridcodes. From a system design perspective, this pushes developers toward: • Advanced EMS architectures • High-performance PCS selection (with dynamic Q control) • Robust testing & validation frameworks ➤ Black Start & Grid-Forming Mandate For projects ≥50 MW, the regulation introduces a powerful requirement: Black start capability + Grid-forming inverter technology This is not a small upgrade—it’s a paradigm shift. Grid-forming (GFM) systems: • Establish voltage & frequency from scratch • Enable system restoration after total blackout • Support weak grid conditions where traditional generation struggles This aligns closely with global trends where grids are moving from synchronous inertia → #inverter-based stability. ➤ Performance Accountability Over 15 Years • ≥90% output after 5 years • ≥80% after 10 years • ≥70% after 15 years This introduces real accountability across the value chain: • Cell selection strategy • Thermal management design • Degradation modelling • Warranty structuring ➤ Solar: Moving Toward Traceability & Durability • Mandatory bypass diodes (reducing hotspot risks) • RFID tagging for lifecycle traceability • 25-year operational design requirement For floating solar: • UV & salt-resistant materials • Wind tunnel validation • Buoyancy testing This signals a move toward bankability through engineering discipline, not just capacity bidding. ➤ Wind Energy ≥500m distance from residential zones (noise mitigation) Offshore-specific requirements: • Scour protection • Marine-grade foundations • J-tube / I-tube cable systems • Offshore substations with helipad access This ensures that India’s offshore ambitions are built on global engineering standards from day one. ➤ Digital Data, Control & Grid Visibility • Remote operability via load dispatch centers • 90-day high-resolution data storage • Fault recording and analytics readiness ➤ Safety & Compliance • Multi-layer protection systems • Fire safety integration • Compliance with National Building Code From where I see it, this amendment does three things: → Only serious, system-level players will survive → Pushes India toward grid-forming future → Shifts focus from CAPEX to lifecycle performance Now is the time to rethink—compliance isn’t just about standards; it’s about building systems that perform for 15+ years. #cea #bess #energystorage #renewables #gridstability #indiaenergy #solarpanel #powersector #blackstart #lfpbattery

Growing electricity costs and the need to climate-proof homes as temperatures rise have prompted the U.S. Department of Housing and Urban Development (HUD) and the USDA to adopt updated energy standards for new single and multi-family homes. These new rules will ensure that homes funded by HUD are built to current standards set forth by the International Code Council for insulation, air sealing, efficient windows, lighting, and heating and cooling systems. This move is crucial to prevent families from having to choose between heating and cooling their homes during extreme weather conditions. HUD estimates that these updates could save households up to $950 annually. Additionally, incorporating these measures into construction can be economically viable, with the upfront costs rolled into Federal Housing Administration mortgages. While some home builders express concerns about increased costs, studies show that the benefits outweigh the initial expenses. Modern energy codes lead to significant savings and promote environmental justice, benefiting low-income and minority households disproportionately affected by high energy costs. https://lnkd.in/gV9bNhQH #EnergyEfficiency #HUD #USDA

Spain just updated its grid-connection technical requirements (Orden TED/82/2026). A lot of projects won’t notice what changed until commissioning, and that’s when it turns into schedule and warranty pain. The update modifies TED/749/2020 and hits three areas hard: small generators, storage, and self-consumption. Here’s the practical view Type A generators (<100 kW): • Voltage dip ride-through aligned with Type B for both balanced and unbalanced faults (e.g., balanced: 0.05 pu for 200 ms) • Power-electronics blocking allowed during faults (1) Blocking if V < 0.2 pu (balanced) (2) Must unblock within 100 ms once V > 0.2 pu   • Active power recovery required after faults (but no mandatory fast current injection) Storage (BESS): • Until a dedicated storage code exists, BESS must meet generation requirements in both export and import modes • Temporary exemption from submitting NTS certificates in the operational notification process • The sleeper detail: blocking/unblocking and recovery behaviour now becomes a commissioning pass/fail item if your model doesn’t match the plant response The sleeper detail: Blocking/unblocking timing and post-fault recovery are now commissioning pass/fail items. If the plant response doesn’t match the accepted model, it becomes a site problem, not a study problem. Small generators connected to distribution in TNP (islands): • LVRT aligned with PO 12.2 SENP (including 0 pu for 500 ms for balanced faults) • Blocking logic per PO 12.2 (0.1 pu balanced/0.55 pu two-phase-to-ground) • RoCoF requirement: 2 Hz/s (750 ms moving window) • Frequency withstand: 47.0–47.5 Hz (3 s) | 47.5–48.0 (1 h) | 48.0–51.0 (unlimited) | 51.0–52.0 (1 h) • 9-month transitional exemption on NTS certificate requirements Self-consumption: The old technical exemption (DT3ª RD 647/2020) is now removed; full compliance required from 12 May 2026 Why this actually matters? These aren’t paperwork changes. They affect controller firmware, protection settings, fault ride-through logic, and EMT/RMS compliance models. Discovered late, they trigger redesign, retesting, and COD delay. And practically, they will separate projects that commission cleanly from projects that slip because the plant’s real fault behaviour no longer matches the model that was approved. For those active in Spain: 👉 If you discovered a gap at commissioning, would you rather (1) re-tune controls and re-test on site, or (2) accept a temporary export cap until firmware/models are updated? #GridCode #Spain #Renewables #BESS #PV #Inverters #PowerSystemStability #GridConnection

"In one upcoming example, companies working on hydrogen fuel cell vehicles will be able to tap a national standard on hydrogen refuelling that will set out guidelines for transporting hydrogen, as well as the operational and safety requirements of refuelling stations. The standard is planned for 2025. A new International Electrotechnical Commission (IEC) standard on electrical energy storage systems will also provide requirements on the monitoring and maintenance of such systems and on integrating them with the power grid, among other things. It is expected to be adopted locally by mid-2024, EnterpriseSG – the national standards and accreditation body – said in a statement on Friday. Other national standards and accreditation programmes in the pipeline include: ● IEC standards on smart grids, to be adopted locally by 2024; ● Standards to ensure the charging infrastructure can support different types of electric harbourcraft, expected to be developed by 2025; ● A methanol and ammonia bunkering standard planned for 2025 to help the local maritime industry transition to sustainable alternative fuels; and ● A Clean and Green Urban Farms accreditation programme for aquaculture farms, set to be ready by 2023, to help the farms adopt a sustainable and quality-assured system in food production." https://lnkd.in/g5wn9sC5

⚡ 🔋 China’s Upcoming EV Battery Safety Standard Sets New Benchmark for Thermal Runaway Protection The new #GB38031-2025 standard for electric vehicle (EV) power batteries is set to take effect in 2026. One of its most critical enhancements: in the event of thermal runaway, 【the battery system must not catch fire or explode within 5 minutes, providing crucial time for passenger evacuation.】 This reflects a growing global emphasis on thermal event containment and occupant safety as EV adoption scales. The upcoming revision strengthens safety requirements across the board — from cell to pack level — and aligns more closely with international standards like UN GTR 20. The standard is being developed with the participation of major OEMs and battery makers such as BYD, CATL, Tesla, and BMW, showcasing the industry’s unified move toward higher safety resilience. Battery safety isn’t just a compliance topic — it’s a trust factor. #EVsafety #LithiumBatteries #BatteryThermalRunaway #ElectricVehicles #ChinaStandards #GB38031 #AutomotiveSafety #EVbattery #BMS #ThermalManagement

U.S. Department of Energy (DOE) has issued its assessment of ASHRAE 90.1-2022 (I look forward to this study by Pacific Northwest National Laboratory every cycle): 🔷 The 2022 version will save about 10% over the 2019 standard. This ~10% (9.8% as published) is a national average estimate of site energy savings for commercial buildings. Similar savings (~9%) will be achieved in source energy and carbon emissions. 🔷 There are new requirements to address thermal bridging, and expanded criteria for whole-building air-leakage testing. This is particularly interesting, we are finally moving beyond U-values. 🔷 Other key changes: Renewable energy systems included as prescriptive requirement; Updated lighting power allowances; Additional guidance for using emissions metrics among others.   https://lnkd.in/gcNGdJM2

China just set the rules for solid-state batteries. The message is clear. Beijing wants to end the marketing chaos. China released its first national standard for solid-state EV batteries on December 30, 2025. Public consultation runs until February 28, 2026. It's a framework that will set standards in the entire industry. It kills the term "semi-solid-state battery." Companies like NIO and WeLion used it freely. Now there are only three categories: • Liquid batteries • Hybrid solid-liquid batteries • Solid-state batteries (all-solid) The threshold is strict. To qualify as "solid-state," weight loss during vacuum drying must stay under 0.5%. Previous guidelines allowed up to 1%. This new limit ensures batteries labeled solid-state are virtually free of liquid electrolyte. The standard also classifies batteries by electrolyte type, ion type, and application. Why does it matter? Without a national standard, companies branded hybrid tech as "solid-state" to attract investors and customers. The confusion hurt credibility. Now China is creating a common language for researchers, manufacturers, and regulators. This is Part 1 of a four-part series. Future parts will cover performance, safety, and durability standards. A separate standard for solid electrolytes is also in the works. By releasing this standard first, China aims to lead international rule-making. And for an industry chasing the next breakthrough, that leadership matters. -- Every week, I publish a free battery newsletter. Join 5700+ professionals : 👉 https://lnkd.in/eaBWN6uX

💾🔌 Interesting and important developments today in the #transmission and #largeload #AI #datacenter space: an Executive Order has been issued by the The White House regarding #datacenters on federal lands with the goals of "protecting national security, preserving our economic competitiveness, revitalizing our energy infrastructure, and ensuring United States leadership in AI." Key provisions in this order direct that such development should be done where capacity can be developed through #reconductoring, and developed using high-performance (a/k/a advanced conductors) and other advanced transmission technologies. The order directs the Secretary of U.S. Department of Energy (DOE) by June 30, 2025 to "engage with transmission providers and transmission organizations owning, operating, or maintaining transmission infrastructure located near Federal sites selected for AI infrastructure to identify any grid upgrades, deployment of advanced transmission technologies such as high-performance conductors ... or other steps expected to be required for extending interconnection services to AI infrastructure by the end of 2027." The order also calls for an #efficiency standard for transmission conductors. This is an important step as modern, advanced conductors like #ACCC can improve line efficiency up to a range of 30 to 40%. MIT noted in a report earlier this year: "... DOE should adopt a national conductor efficiency standard. This would ensure that transmission providers install more efficient transmission lines, which can reduce line electricity losses by 30 percent. Between 2018 and 2022, annual electricity transmission and distribution losses averaged about 5 percent of all electricity transmitted and distributed in the United States. Approximately one third of those losses occur in the transmission of electricity... increased efficiency has no downsides." https://lnkd.in/ebYWWHyt The Executive Order recognizes the critical element that is TIME, directing steps to extend interconnection services by the end of 2027. Advanced conductors (a/k/a high performance conductors) are the only technology that we have that can double transmission capability 365/24/7 in a matter of months and be relied on in planning cases and interconnection studies. These conductors are mature, widely deployed, and ready to go. And as an (important) bonus, low sag, low temperature carbon composite advanced conductors also mitigate wildfire risk.
