The scope of the letter expands the strategic cooperation agreement signed by both parties in January 2017, the Polish ministry said.
Finance and Investment Minister Jerzy Kwiecinski, present at the signing ceremony, said that the Polish government places great emphasis on both the transformation of the energy system and the security of energy supply, and that these two goals can be achieved in cooperation with leading technology suppliers, such as GE.
He added that Polish-US cooperation had entered a new stage in the power sector and talks are being held on the use of gas as an energy material allowing for the transition to a low-carbon economy, but the Polish government is also increasingly interested in using renewable sources.
"In the future we would like renewable energy sources to be the basis of the Polish energy sector and we want to use GE's experience in these new technologies," Kwiecinski said, adding that a special focus is given to offshore energy where investments are estimated at PLN 100 billion (EUR 23.4 bln).
According to US Ambassador to Poland Georgette Mosbacher, also present at the ceremony, the signing of the letter enables the Polish government and GE to cooperate more closely for the development of Poland as a hub for offshore wind power.
In her view, Polish-US cooperation in gas and renewable energy will improve energy diversification and security, which is a pillar of national security.
She also said that GE owns the the most advanced energy technologies, including the world's most powerful offshore wind turbine Haliade-X, featuring a 12MW capacity.
An offshore turbine is only a small element of the cooperation, GE Renewable Energy Vice President Fabrice Kermorgant said, adding that everything else must be developed on site, in Poland - ports, shipyards, factories of structural and electrical components. (PAP)
