The energy company will use the EIB loan to invest in the electricity grid and to connect more renewables.
It will be used to upgrade Britain’s power grid, improve networks and connect new power generation.
The loan will include capital investment by National Grid to enhance infrastructure between the Wirral, Scotland and the London Power Tunnels.
National Grid global tax and treasury director Malcolm Cooper said: "The significant European Investment Bank loan will be used to fund infrastructure investment and build an electricity network for the future."
EIB vice president Jonathan Taylor said: "Investment in the UK electricity transmission network is essential to prepare for future demand, connect new sources of renewable energy and upgrade old facilities.
"This agreement, the largest ever single loan to be provided by the European Investment Bank, reflects both the scale of energy investment needed and National Grid’s own experience in implementing such a diverse capital investment programme."
The programme, which is being backed by the EIB, will also feature enhancements to protect critical infrastructure from floods.
It will offer substation capacity required for new connections to offshore wind farms and new interconnectors to continental Europe.
The EIB said it has provided £5.7bn for investment since 2009 in energy infrastructure, including electricity distribution, offshore transmission links, energy efficiency, interconnectors to the continent and wind farms like London Array and West of Duddon Sands.
