Net zero is barely enough to help with climate goals, given how late we are. It's not a huge goal, it is the absolute bare minimum to avoid >2 degrees of warming.
The real issue is the cost of keeping gas peaker stations around that are mostly idle and fire up only a few days a year, but that's an economic issue, not an engineering one.
In the longer term, you could even run them off net-zero renewable syngas that you make the rest of the year using low-cost electrical power at peak solar generation times; you only need to store a relatively small amount of it, and old fossil fuel reservoirs are ideal for this.
