‘The Market Design Must Evolve’: Eku Energy on Energy Storage in Australia’s NEM

Why It Matters

Without a modernized market design, storage projects may remain financially unattractive, slowing the transition to a low‑carbon grid and risking supply stability as renewables dominate the NEM.

Key Takeaways

• Market rules limit storage revenue potential
• Clear price signals needed for storage profitability
• Interconnection delays hinder rapid deployment
• Coordinated planning improves grid reliability
• Policy certainty drives investor confidence

Pulse Analysis

Australia’s National Electricity Market is at a crossroads as renewable generation surges and traditional coal plants retire. Energy storage, particularly battery systems, offers the flexibility to balance supply and demand, but the current market architecture often undervalues its contributions. Eku Energy’s recent briefing underscores that scarcity pricing, limited ancillary service remuneration, and fragmented interconnection procedures create a financial cliff for storage developers. By aligning market incentives with the operational realities of batteries—fast response, short‑duration discharge, and rapid cycling—the NEM can unlock billions of dollars in investment.

A reformed market design would introduce several key mechanisms. First, dynamic scarcity pricing that reflects real‑time scarcity can capture the true value of storage during peak events. Second, dedicated ancillary service products, such as fast frequency response, should reward storage for grid‑stabilising actions. Third, a streamlined, transparent interconnection pathway would cut approval times, allowing projects to move from concept to commissioning faster. These changes not only improve the economics for storage owners but also enhance overall system resilience, reducing the risk of blackouts as variable renewable output fluctuates.

The broader implications extend beyond the NEM’s borders. As other jurisdictions grapple with similar integration challenges, Australia’s approach could set a benchmark for market‑driven storage adoption. Policymakers, investors, and utilities alike will watch how Eku Energy’s recommendations influence regulatory reforms. A more storage‑friendly market promises lower wholesale prices, greater renewable penetration, and a smoother path to Australia’s net‑zero emissions target, reinforcing the country’s reputation as a leader in energy transition innovation.
