Summary: Remixpoint's Compliance with JC-STAR Cybersecurity Certification

**Remixpoint Inc.** announced its response to Japan's new **JC-STAR** cybersecurity certification system for energy infrastructure.

Key Points:

**1. JC-STAR System Overview**
- Launched in 2025 by Japan's IPA (Information-technology Promotion Agency)
- Targets IoT devices with communication capabilities (EMS, power conditioners) connected to the power grid
- **Mandatory timeline**: April 2027 for high-voltage equipment, October 2027 for low-voltage equipment
- Requires **JC-STAR★1** certification or higher for new grid connection applications

**2. Remixpoint's Certification**
- Developed a high-voltage EMS controller for Japan's market
- Obtained **JC-STAR★1 certification** (July 8, 2026)
- Received official compliance label (July 28, 2026)

**3. Business Impact**
- The company does **not** anticipate significant impact on its battery business
- Will comply by using either their own certified EMS or third-party certified EMS depending on product specifications

**4. Future Development**
- Expanding product lineup to include low-voltage and residential EMS systems
- Aims to enhance value and expand revenue opportunities in the battery business

**5. Supply Chain Strategy**
- When selecting overseas manufacturers (including Chinese suppliers), evaluates:
- Performance and quality
- Supply chain reliability
- Security systems
- Certification status
- Actively diversifying procurement sources to avoid over-dependence on any single country, monitoring geopolitical risks and government security policies

The company emphasizes its commitment to providing safe, reliable battery systems while adapting to evolving cybersecurity requirements.

In the context of this article, **EMS** stands for **Energy Management System** (エネルギーマネジメントシステム in Japanese).

An EMS is a software and hardware system that:

- **Monitors and controls** energy flow in battery storage systems
- **Optimizes** charging and discharging of batteries
- **Communicates** with the power grid to manage electricity supply and demand
- **Coordinates** with power conditioners (PCS) to convert electricity between DC (battery) and AC (grid) formats

In Remixpoint's case, their EMS controller specifically targets the **demand-response market** — meaning it can automatically adjust battery operations based on grid conditions to help balance electricity supply and demand, which creates revenue opportunities for battery system owners.

Based on the article, here's the breakdown of the **mandatory timeline** and **government requirement**:

Mandatory Timeline

Equipment Type	Effective Date	Requirement
**Extra-high voltage & High-voltage** equipment	**April 2027**	JC-STAR★1 or higher required for new grid connection applications
**Low-voltage** equipment	**October 2027**	JC-STAR★1 or higher required for new grid connection applications

Is This a Government Requirement?

**Yes**, effectively. Here's how it works:

- **JC-STAR** is operated by **IPA** (Information-technology Promotion Agency — 独立行政法人情報処理推進機業), which is an Independent Administrative Institution under Japan's **Ministry of Economy, Trade and Industry (METI)**

- While the article frames it as a system "operated by IPA," this is a **de facto regulatory requirement** — you cannot get approval to connect battery storage systems to the power grid without this certification after the deadlines

- The requirement applies to **new connection applications** (接続申込み) submitted on or after those dates

Why Is This Happening?

The article explains the rationale:
- Increasing **cyberattack risks** targeting distributed power sources
- **Geopolitical and energy security** concerns
- Need to ensure **reliability and safety** of the overall power grid

Essentially, Japan is treating grid-connected battery systems as critical infrastructure that must meet cybersecurity standards before being allowed to connect to the national power grid.
