What would you need to replace a 1 GW nuclear power plant with 98% capacity factor?

Probably 1 GW solar power plant, together with 1 GW onshore wind and 1 GW of gas power plant. Then you have to also pay the natural gas to compensate for times of low solar + wind production. You can build battery storage to decrease the natural gas consumption, but how much battery storage do you have to build and how much can you reduce the natural gas consumption strongly depends latitude and local weather patterns.
