They added that revenue will potentially exceed $15 billion over 20 years."The sector has access to technology and capital but still struggles to deliver infrastructure consistently and within the required timelines. What we have built with Tesla is an ecosystem that enables alignment between capital and execution, and that can be replicated across multiple markets," said Fabrizio Zago, CEO of NatPower.(Reporting by Simon Jessop in LondonEditing by Matthew Lewis)Terms and Privacy PolicyPrivacy & Cookie SettingsMore Info
