In March, 1,147MW of new capacity was connected. QLD was the only region to enjoy an increase in Generator Weighted Average prices, while wind weighted prices fell for all regions. SA solar and wind suffered the most curtailment. VIC was the dominant energy exporter and NSW the largest importer.

February brought no new connections to the NEM. Generator-Weighted Average prices improved for solar and wind across most regions, except QLD. Solar and wind farms continued to face large curtailment. VIC was the dominant energy exporter while TAS was the biggest importer in February.

The NEM added 185MW capacity in January. Generator-Weighted Average prices declined for wind and solar farms in most regions, with solar farms facing deeper discounts to Time-Weighted Average prices. Solar curtailment remained high, particularly in SA. QLD's reliance on NSW during peak demand grows.

In 2024, record new generation capacity joined the electricity market. Wind weighted prices were at record lows for all regions except SA, while higher daytime prices improved solar farm performance across the NEM. Broader ranges in operational demand across regions intensified market volatility.

The NEM expanded its capacity by 121MW in November. Warm temperatures plus extended baseload outages contributed to tight supply-demand balance, driving exceptional NEM Generator-weighted Average price growth in November, with NSW and QLD leading gains.

The NEM expanded its capacity by 167MW in October. While demand remained at historical lows, Generator-weighted Average prices strengthened across most regions. VIC continued to experience persistent negative prices, causing energy flows to shift towards regions with more favourable pricing.

NEM capacity grew by 340MW in September. Strong winds and mild weather led to lower demand and extensive curtailment, depressing Generator-Weighted Average prices. Many farms increased reliance on Large-scale Generation Certificates for revenue. TAS transitioned from importer to net exporter to VIC.

NEM capacity grew by 1,678MW in August. With temperatures rising, energy demand dipped, while consistent strong winds boosted supply, resulting in large curtailments and declined Generator-Weighted Average prices in most NEM regions. TAS still depended on VIC energy exports due to hydro shortage.

The NEM added 311MW of new generation capacity in July. Calm and cold weather conditions in SA, VIC, and TAS at the end of the month led to low wind output and market volatility. Gas generation increased to compensate. VIC exports to TAS reached record high levels for July.

NEM fossil fuel generation ramped up to offset the lowest wind generation for June in seven years. In Tasmania, hydro generation fell to the lowest level since 2009, Tamar Valley fired up for the first time in five years, and energy imports from VIC were the highest for June since 2017.

There were 861MW of new generation connections in May. Despite rising wind and solar Generator-Weighted-Average prices, most NEM regions continued to have large discounts to their Time-Weighted-Average prices. Additionally, most NEM regions reported lower wind and solar curtailment rates.

The NEM continues to wait for the first new generation connection for 2024, marking the longest stretch with no new connections since 2018. Wind and solar generators performance fell in April with larger discounts to the spot price. In brighter news, wind and solar curtailment continues to fall.
