## Abstract
This INL white paper synthesizes the grid services provided by Battery Energy Storage System (BESS) technology, assesses its architecture and communications, and critically evaluates these systems against the principles of Cyber-Informed Engineering (CIE). The primary motivation is to address significant national security and supply chain risks stemming from the heavy reliance on Foreign Entities of Concern (FEOC) components in the U.S. BESS supply chain. The paper proposes a framework, operationalized through CIE, allowing asset owners and buyers to evaluate BESS implementations, Inverter-Based Resources (IBR), and Energy Management Systems (EMS) to ensure functional assurance and acceptable risk levels, irrespective of immediate supply chain trust validation.
## Research Objective
The primary objectives are to:
1. Synthesize the crucial grid services and architecture of BESS technology.
2. Assess the architecture and communications of BESS components.
3. Present a case study analysis applying Cyber-Informed Engineering (CIE) principles to BESS to evaluate risks and solutions.
4. Create an operationalization roadmap for using CIE to enable safe domestic operation and integration of American vendor products within the supply chain.
## Methodology
### Approach
The research employs an analytical approach centered on applying the principles of Cyber-Informed Engineering (CIE) to the BESS lifecycle. This includes:
1. **Causal Analysis:** Identifying potential cybersecurity compromises through misuse analysis.
2. **Engineering Analysis:** Incorporating security controls directly into the system design (engineering controls) to reduce or eliminate the impact of a compromise.
3. **Consequence-Based Prioritization:** Utilizing a modular consequence-based assessment framework to prioritize supply chain components that significantly influence strategic security decisions.
4. **Mitigation Evaluation:** Testing and evaluating proactive mitigation strategies against cost implications, particularly concerning non-domestic sourced infrastructure.
### Dataset/Environment
The study focuses on:
- Battery Energy Storage Systems (BESS) technology, including its architecture and communication protocols.
- Inverter-Based Resources (IBR) and Energy Management Systems (EMS) integrated with BESS.
- Supply chain components, specifically addressing the risks associated with Foreign Entities of Concern (FEOC) sourced materials (e.g., referencing the Camp Lejeune incident involving Chinese-made hardware).
### Tools & Technologies
The document leverages established cybersecurity and engineering concepts, referencing:
- Existing cybersecurity standards for inverters and batteries (e.g., IEEE 1547.3-2023 and UL2941), noting their development under the assumption of a domestic supply chain.
- Control mitigation frameworks, implicitly referencing industry models like MITRE ATT&CK for ICS and ISA/IEC 62443-4-2.
## Key Findings
### Primary Results
1. **CIE as the Path to Functional Assurance:** CIE practices are identified as the critical next step for gaining functional assurance and achieving an acceptable level of risk for BESS, even when reliance on foreign hardware persists.
2. **Supply Chain Vulnerability:** The U.S. energy sector faces substantial national and energy security risks due to heavy reliance (>80% global raw material control by some actors) on FEOC components for BESS supply.
3. **Standards Shortcomings:** Current cybersecurity standards (e.g., IEEE 1547.3) may inadequately address real-world security scenarios because they were developed assuming predominance of domestic supply chains.
4. **Integrated Control Schemes:** Combining engineering controls (identified through in advance causal analysis) with misuse analysis-derived cybersecurity controls results in an enhanced control scheme addressing overall BESS security holistically.
### Supporting Evidence
- Reference is made to high-visibility incidents, such as the removal of Chinese-made batteries at Camp Lejeune, highlighting immediate national security concerns related to FEOC hardware.
- Mention of international reports detailing geopolitical espionage risks against energy infrastructure (e.g., Russia spying on Danish wind farms, China reconnaissance on offshore wind).
### Novel Contributions
- The presentation of a practical framework for asset owners/buyers to perform security analysis on BESS implementations using CIE principles retrospectively or proactively.
- The development of an operationalization roadmap for implementing CIE throughout the energy transition lifecycle for BESS components.
- The proposal of consequence-based prioritization specifically tailored to supply chain components influencing strategic manufacturing and security decisions.
## Technical Details
The research advocates for a dual-layer control strategy:
1. **Engineering Controls:** Controls derived from analyzing the *means* by which a system *could* fail or be misused (Causal Analysis in advance). These controls are embedded conceptually in the design phase to reduce system vulnerabilities structurally.
2. **Cybersecurity Controls:** Controls derived from analyzing *how* an adversary might exploit the system (Misuse Analysis).
The integration of these two layers—engineering resilience layered with specific cybersecurity defenses—is presented as the most robust approach to safeguarding BESS assets against known and emerging threats, mitigating risks inherent even in foreign-sourced components.
## Practical Implications
### For Security Practitioners
Practitioners should prioritize lifecycle security integration, recognizing that security cannot be bolted on later. They must incorporate CIE thinking by performing proactive causal analysis before deployment or procurement.
### For Defenders
Defenders must implement strategic, short-term operational mitigations immediately to secure existing Operational Technology (OT) systems reliant on potentially compromised supply chains, while supporting long-term goals of domestic supply development via BIL funding.
### For Researchers
Future efforts should focus on refining the modular consequence-based assessment framework and integrating and refining CIE findings to adapt to evolving BESS architectures and threats, particularly concerning the implications of emerging global standards on FEOC assets.
## Limitations
- The research acknowledges that the complexity and eventual implications of current standards (like IEEE 1547.3) may be under-appreciated because they were developed under the assumption of a domestic supply chain dominance.
- The practical impact of applying cybersecurity controls to FEOC-sourced assets may be inherently limited by the testing and certification processes occurring physically within FEOC territories.
## Comparison to Prior Work
This work significantly advances prior approaches by transitioning CIE from a theoretical concept toward an operational and implementation roadmap specifically for BESS. Unlike reliance solely on compliance with nascent standards (like IEEE 1547.3), this white paper emphasizes proactive, inherent security design via engineering controls layered alongside traditional cybersecurity mitigations to address supply chain trust deficiencies directly.
## Real-world Applications
- **Procurement Assurance:** Asset owners can use the proposed framework to rigorously vet BESS products, IBRs, and EMS solutions prior to purchase and implementation.
- **Risk Mitigation Strategy:** Developing tailored packages of cost-evaluated solutions for existing installations facing geopolitical supply chain risks.
## Future Work
- Continued refinement of CIE methodologies to adapt to changing BESS operating conditions and emerging geopolitical threats.
- Further analysis of the cost implications associated with security enhancements versus the geopolitical risk imposed by non-domestic components.
