This report finds that continued transmission delays are driving up consumer electricity bills for households and businesses, threatening energy reliability and risking emissions reduction targets. The costs of inaction to deliver transmission on time must be considered in policymaking.

Nexa Advisory is calling for national coordination and accountability to deliver the nation-building transmission infrastructure required. This includes accountability on the delivery dates firmed up in the Renewable Energy Target Agreements or other agreements such as the Capacity Investment Scheme between the Federal and State governments; identifying and funding the cost of delays; and working with communities to build social licence, which has been a key roadblock to timely development.

This analysis highlights the benefits of timely transmission infrastructure development for consumers, namely the downward pressure exerted on wholesale energy prices and therefore consumers’ bills and the improved reliability outcomes for our future energy system.

Key findings

Key findings derived from the modelling and analysis consider:

• Wholesale Market Prices
• Residential customer bills
• Business consumers are significantly impacted
• Reliability Impact
• New transmission will reduce dependence on gas
