The lighting of blast furnace four not only marks the completion of a sophisticated £185 million engineering effort, but also signals Tata's commitment to the future of steel-making in Wales.
There is no denying the challenges that steel companies like Tata are facing in difficult global markets.
During my recent meeting with the company's senior executives and union representatives in Port Talbot, we were able to discuss how Government and the organisation can work together to ensure Tata' s UK operations can remain competitive.
The restarting of the furnace will go some way towards that aim, and I look forward to making a return visit to Port Talbot to see it in full operational mode in the near future.
