It improves grid management, sustainability, and scalability, outperforming traditional methods while remaining practical regardless of quantum hardware limitations.
Regulatory & Policy Framework for Grid Modernization
In Grid modernization, regulatory frameworks and standards play a crucial role, ensuring safety, sustainable integration, and interoperability of advanced technologies. Here, Stellarix can guide companies in staying ahead of the shifting regulatory landscape by decoding the complex global framework and compliance, ensuring grid modernization investments are not only compliant but also strategically positioned to capitalize on emerging policy initiatives.
Below are some regulations for grid modernization:
Action Plan for Affordable Energy
In February 2025, under the Clean Industrial Deal, the European Commission’s Action Plan for Affordable Energy aims to improve affordability, sustainability, and efficiency across the EU’s energy system. The plan centers on market optimization through tariff reforms and grid investments, accelerating clean energy via electrification and renewables, and investing and digitalizing to mobilize private capital and drive innovation. Additionally, it strengthens energy resilience through crisis response measures and a Tripartite Contract for price stabilization, ensuring long-term affordability.
Federal Energy Regulatory Commission, Order No. 2023
In July 2023, to accelerate the implementation of sustainable energy, the U.S. Federal Energy Commission issued FERC Order No. 2023, which simplified the interconnection process. By using first-come, first-served cluster studies, strict timelines, and penalties for delays, it promotes openness, effectiveness, and equity in connecting new energy projects to the grid. By requiring advanced modelling, it also improves grid planning and allocates costs more fairly, preventing developers from being unfairly burdened. The goals of these measures are to eliminate bottlenecks, enhance grid stability, and ease the shift to a cleaner energy system.
Australian Energy Sector Cyber Security Framework (AESCF)
The Australian Energy Market Operator (AEMO) and the Australian government collaborated to launch the AESCF in 2018 as a voluntary program that enabled energy organizations to assess and improve their cybersecurity maturity, thereby strengthening the resilience of Australia’s critical energy infrastructure. In July 2024, energy ministers reaffirmed their continued support for AESCF. The AESCF would continue to perform self-assessments to support the cyber uplift programs, the prioritization of investment, and the Risk Management Plan (RMP) regulatory obligations under the SoCI Act.
