Letter by Rabbi Chaim Kanievsky about Using Electricity on Sabbath

An addition handwritten and signed by Rabbi Chaim Kanievsky on a photocopy of a letter by Rabbi Azriel Auerbach.
The content of the letter: "About observing the holiness of the Sabbath when using electricity on Sabbath, since unfortunately the system producing electricity is operated on Sabbath and God fearing people who fear the holiness of observing the Sabbath and especially Bnei Torah should avoid enjoying and using electricity … we stand by those who are planning a new generator in our neighborhood".
Rabbi Kanievsky also added "Of course it is a great Mitzvah … and will merit sons Torah scholars … Chaim Kanievsky".
