The Final Determination on ‘National Electricity Amendment (Unlocking CER benefits through flexible trading) Rule 2024’

October 4, 2024

In a previous article, we had covered the what the ‘DRAFT National Electricity Amendment (Unlocking CER benefits through flexible trading) Rule 2024’ was proposing, as the final determination was made on the 15th of August, we have decided to revisit the topic and point out any differences to the draft and the proposed timeline of implementation.

The proposed live date for what the new rule is proposing is the 2nd November 2026.


What are the differences between the final determination and the draft?

A few changes and clarifications have been made between the two documents, some of which are from stakeholder feedback, these include:

  • NMI Service Provider Role: Initially, DNSPs were proposed to establish and maintain NMIs. The final determination assigns this role to a new accredited NMI service provider, reducing costs and implementation time. This role is equivalent to an embedded network manager role and would be provided to a contestable party.



  • Large Customer Eligibility: The final rules clarify that large customers can aggregate loads across multiple sites to meet the threshold for flexible trading, which was not explicitly detailed in the draft.



  • De-energisation Rules: The final determination prohibits separate de-energisation of secondary settlement points (SSPs – Secondary Settlement Points) to protect vulnerable consumers, a change from the draft rules.



  • Technical Requirements: Stakeholders provided feedback on metering requirements, such as the need for meters to have alternative data access methods (e.g., smartphone apps) and concerns about flow limits and accuracy. The final determination retains the draft position but incorporates stakeholder feedback to ensure practical implementation this includes ensuring that meters are accurate and capable of handling the required flow limits without compromising performance.




  • Market Participant Roles: Stakeholders expressed concerns about the complexities of compliance with dynamic operating envelopes and the allocation of tariffs. The final determination addresses these concerns by outlining clear roles and responsibilities for market participants.




Timeline of Implementation

As this is a fairly big change, there will be different stages of implementation, as such, we have provided a timeline of events below. Please note that the timeline in the ‘Final Determination’ is still a draft and will have to be finalised by the 30th September 2025. Please note that the ‘Final determination’ was a month late, so it is likely the below will be delayed.

  • 15th August 2024: Final determination made.



  • 29th August 2024: removal of the requirement for meters to have a visible display (to accommodate in-built meters with displays on an app).



  • 30th September 2025: AEMO guideline and procedure changes.



  • 31st May 2026: arrangements related to type 9 metering.



  • 1st November 2026: arrangements related to meter types 8A and 8B, SSPs, and changes to the NERR and retail contracts (the live date).


No other details are provided beyond this.

Introducing Malaysia’s Corporate Renewable Energy Supply Scheme (CRESS) Malaysia is taking a significant step towards a greener future with the planned launch of the Corporate Renewable Energy Supply Scheme (CRESS) this September. This initiative, part of the GREENS MADANI Initiative, aims to enhance corporate access to green electricity and support the country’s energy transition goals. What is CRESS? CRESS is a framework designed to allow renewable energy producers and corporate consumers to arrange green electricity supplies through an open grid access model. This means third parties can supply or acquire electricity via the grid network system with a predetermined system access charge. Framework and Parties Involved Under CRESS, renewable energy producers and eligible corporate entities can negotiate and agree on terms for green electricity supply. The Energy Commission will regulate the program, while the Single Buyer (SB) and Grid System Operator (GSO) will manage market and system operations. Tenaga Nasional Berhad (TNB) will continue as the electricity utility supplier, ensuring consistent delivery of electricity.

To unlock the full potential of the growing Battery Energy Storage System (BESS) market, it's crucial to correctly assess returns to attract more investment in sustainable energy projects. With the rapid evolution of energy technologies and market dynamics, investors and developers alike face challenges in evaluating risk-adjusted returns, which are essential for securing funding and ensuring the financial success of these ventures. Without accurate and comprehensive assessments, projects risk being underfunded or failing to achieve their intended outcomes, stalling progress in the clean energy transition. Risk-adjusted returns for Battery Energy Storage System (BESS) projects measure the profitability of the investment while accounting for the risks involved. This is crucial because BESS projects can have significant financial and operational risks, such as technology failures, regulatory changes, and market volatility. Key Factors in Risk-Adjusted Returns for BESS Projects Revenue Streams : BESS projects can generate revenue through various means, including energy arbitrage, frequency regulation, and capacity payments. Each revenue stream has its own risk profile. Cost Considerations : Initial capital costs, operational and maintenance costs, and potential costs related to technology failures or safety incidents must be factored in. Market Risks : Fluctuations in energy prices, changes in regulatory policies, and competition from other energy sources can impact returns. Technological Risks : The reliability and lifespan of the battery technology used can affect the project’s financial performance. Incidents like thermal runaways or other failures can lead to significant losses. Financial Metrics : Common metrics used to assess risk-adjusted returns include the Sharpe ratio, which measures the excess return per unit of risk, and the Sortino ratio, which focuses on downside risk. A thorough project-level analysis is essential to accurately assess the financial viability of a BESS project. This includes evaluating technical merits, market conditions, and potential risks to optimise returns and ensure long-term success. How We Can Help At VPP Partners, we specialise in helping companies identify and quantify the risks associated with BESS projects. Our structured approach ensures that all potential risks are thoroughly assessed and managed. Here’s how we can assist: Risk Mapping : Mapping your opportunity against your risk appetite and risk tolerances. Initial Assessment : We conduct preliminary meetings to understand your project’s scope, goals, and context. Risk Identification : Using techniques like brainstorming sessions and expert interviews, we identify risks related to technology, market, finance, and operations. Risk Analysis : We perform qualitative and quantitative risk analysis using tools like Failure Mode and Effects Analysis (FMEA) and decision tree analysis. Risk Quantification : We use statistical models and financial metrics to estimate the cost implications of risks. Risk Mitigation Planning : We develop strategies to mitigate identified risks, including preventive measures, contingency plans, and insurance options. Risk Tracking & Governance : Develop value at risk tracking and controls to ensure operations can be adapted as markets and technology changes. Implementation and Monitoring : We help implement risk mitigation strategies and monitor their effectiveness, ensuring your project stays on track. Reporting and Communication : We prepare regular reports and conduct meetings to keep stakeholders informed about risk management activities and outcomes. By partnering with us, you can ensure that your BESS projects are not only profitable but also resilient to the various risks they may face.
