Government policies and systems

The net-zero transition has become a common direction for global energy development, and Taiwan also has a long-term goal of net-zero emissions by 2050, continuously promoting the transformation of the power system and the adjustment of the energy structure. In recent years, policy focus has been on improving grid resilience and introducing key technologies such as energy storage, supporting the stable development of renewable energy and distributed power sources through grid infrastructure investment and institutional design.


At the regulatory level, with the amendment to the Electricity Act in 2025 and the formal inclusion of "specific electricity supply businesses" into the management system, emerging resources such as energy storage and demand response have established their legal status. Through electricity license review, the Verified Power Storage Project (VPC) system, and related operational management regulations, the government is gradually guiding the industry from demonstration applications to institutionalized and large-scale development, ensuring that electricity trading and energy storage applications operate steadily on the basis of compliance and safety.

Parallel Review Regulations and Setting Safety Regulations

Issued on August 17, 2011

Front-to-meter (FTM) energy storage is the main type.

(Grid-connected lithium-ion battery energy storage system)

 1. Setting Objectives and Compliance Core

Grid-connected energy storage systems are primarily designed to provide ancillary services to the power system. To comply with the new regulations implemented in 2025, their installation and operation have been incorporated into the "Specified Power Supply Business" management framework. They must also complete phased reviews, site verification (VPC), and land use compliance procedures in accordance with regulations to simultaneously meet grid demands and regulatory requirements.


 2. Site Selection and Applicable Areas

Based on current regulations and practical experience, grid-connected energy storage is mostly preferentially installed in industrial parks or corresponding usage zones with relatively complete fire protection facilities and mature management conditions. Common feasible installation areas include:

  • Designate industrial zones and science and technology industrial parks.
  • Urban planning industrial zones (special, Class A, Class B).
  • Apply for entry within the aforementioned industrial park, or set up within the factory area (including outside industrial parks) of a factory holding a valid factory registration certificate.

The actual conditions for setting up the facilities still need to be met on a case-by-case basis, and construction can only proceed after the land use, setting up review, fire protection and other related compliance procedures are completed.

Version 114.11.3 (Revised)

Expanding to off-meter storage (BTM)

(Including factories, shopping malls, hospitals, communities, etc.)

1. Setting Objectives and Compliance Core

  • Application benefits: The main objectives are to enhance the resilience of enterprises' electricity consumption, peak shaving and valley filling (optimizing contract capacity costs), and backup power. Subject to compliance with user contract terms and relevant Taipower programs, it is possible to evaluate the integration of an Energy Management System (EMS) with demand response or related electricity management mechanisms to create extended benefits.
  • Compliance Focus: Off-meter energy storage generally does not require an electricity license; its core compliance focuses on electrical safety, fire safety certification, and equipment/system verification (such as VPC). Billion Watts assists in assessing load characteristics and site conditions from the initial project stage and incorporates actual operating scenarios into the overall planning, reducing compliance risks in the subsequent setup and operation phases.


2. Site selection planning and applicable areas

  • Basis for installation: In accordance with the spirit of current regulations and practical experience, the installation of energy storage equipment in existing factories can generally be regarded as ancillary facilities, and the "existing factory registration certificate" is the main legal basis for installation (however, the actual determination and applicable conditions shall be subject to the regulations of the local competent authorities and the results of case review).
  • Asset and insurance considerations: Billion Watts incorporates the IEC/CNS 62933-5-2 site verification standard and fire safety certification planning during the design phase. The high-standard compliant design not only enhances the overall safety of the factory area, but also helps to strengthen insurance assessment conditions and improve the feasibility and completeness of property insurance underwriting.

The revised "Guidelines for Improving Fire Safety Management of Energy Storage Systems," issued on November 3, 2025, has expanded its application from primarily applying to pre-meter grid-connected lithium-ion battery energy storage systems (FTM) originally issued on August 17, 2022, to include post-meter user-end energy storage systems (BTM), covering diverse installation sites such as factories, shopping malls, hospitals, and communities. This marks the formal entry of Taiwan's energy storage fire safety management into a stage of comprehensive regulation and institutionalization.

Equipment safety

  • Critical component certification

    • Batteries and PCS: Battery cells, modules, and power regulation systems (PCS) must all obtain a full set of test certificates in accordance with relevant national standards such as IEC 62619, UL 1973, or CNS.
    • Design Review: The above certificates must be included in the "Design Review" document before construction and approved by the Bureau of Standards, Metrology and Inspection or a designated inspection agency before installation can commence.

  • Energy storage system on-site verification

    • System Standards: System integration and on-site construction shall be carried out in accordance with Taiwan National Standard CNS 62933-5-2 (Safety Specifications for Grid-Integrated Energy Storage Systems).
    • VPC Validation: After completion, a third-party impartial organization must conduct an on-site safety test (SAT) and obtain a Virtual Power Storage Project Validation (VPC) certificate. This certificate is an absolute prerequisite for applying for a "Specified Power Supply Business" license and completing the formal parallel connection procedure with Taipower.
    • Compliance Procedures: Only after completing the full validation at the equipment and system levels can subsequent grid connection, registration, or operation-related procedures be carried out according to the installation type (pre-meter/post-meter) and applicable regulations.

Fire safety

  • Fire risk assessment and professional visa

    • Pre-construction assessment: A "Fire Risk Assessment Report" must be completed in accordance with the latest guidelines. The assessment should be rigorous, covering the installation location, system type, capacity, fire protection duration, emergency response, and water supply conditions.
    • Engineer certification: The entire fire protection design must be designed and certified by a qualified fire protection engineer. The certified documents must be included in the Bureau of Standards' design review, site inspection, and subsequent verification processes to ensure compliance with regulations.

  • Fire safety equipment configuration

    • Based on the energy storage system type and risk assessment results, a multi-layered protection network is constructed:
    • Active fire suppression and venting: Automatic fire suppression equipment (water spray/mist) and anti-deflagration mechanical ventilation devices are installed to force venting before gas accumulation, thus interrupting the thermal runaway chain.
    • Detection and early warning: Automatic fire alarm equipment (smoke and heat detection) is installed, and thermal imaging temperature monitoring is added as an auxiliary early warning mechanism as needed.
    • Flexible configuration: For specific energy storage technologies (such as flow batteries and fuel cells), the equipment configuration can be adjusted according to the risk assessment results to meet the needs of diverse technology development.

  • Safe distances and fire zoning

    • Perimeter Protection: Strictly enforce the legally mandated safe distances between energy storage systems and buildings, public roads, and public hazardous materials facilities.
    • Space Optimization: By installing firewalls or equivalent protective facilities with a fire resistance period of at least 2 hours, the safe distance can be reduced according to regulations, improving land use efficiency while adhering to compliance.
    • Restricted Areas: Strictly prohibit the installation within refuge routes, firebreaks, or driveways to ensure unobstructed fire and rescue routes.

  • Emergency Response and Maintenance Management

    • Emergency Response Plan (ERP): Develop and implement an emergency response plan that includes procedures for power outage, isolation, notification, and post-incident handling.
    • Regular Inspection: Fire safety equipment must be included in regular inspections and reporting in accordance with Article 9 of the Fire Services Act.
    • Control Measures: Clear warning signs (such as voltage and chemical hazard labels) and personnel access control measures should be set up in the system area.

At the early stages of the project, Billion Watts simultaneously implemented CNS / IEC 62933-5-2, VPC site verification, and the latest fire safety management guidelines. This integrated assessment of fire protection, structure, electricity, and actual operating conditions to help owners balance safety, space efficiency, and long-term maintenance feasibility while complying with regulations, thereby reducing the risks of later reinforcement and operation.

Required preparation items

  1. Land and building use rights certificate: Depending on the identity of the installer, attach land/building ownership documents or use certificate with the consent of the owner; for government-managed sites or existing factory sites, it can be processed based on the approval documents of the competent authority or factory registration certificate.
  2. Installation and Safety Compliance Documentation: In accordance with the latest regulations in 2025, a fire risk assessment, fire safety design, and relevant professional certifications must be completed as important bases for installation and review.
  3. Equipment and system validation documentation (as applicable): Depending on the setup type and review requirements, submit relevant equipment testing, system validation, or field validation (VPC) documentation.

Energy Storage System Verification and Review System Standards

Before construction
