LTESA tender rules

Long-Term Energy Service Agreements, or LTESAs, provide revenue certainty for private investment in new renewable energy generation, firming and long-duration storage, which help to secure finance for project construction.

LTESAs are part of the Electricity Infrastructure Investment Safeguard, a framework to ensure orderly and efficient investment to meet the needs of the electricity system. 

Under this Safeguard framework, the Consumer Trustee will ensure planning for the generation and firming capacity required in NSW will be undertaken in a structured and coordinated manner.
