Why would the MPUC let Xcel Energy decommission powerhouses that are currently powering the grid to build new gas fired facilities? Seems like the consumers are going to have to pay twice. After all the consumer is the ones paying for these facilities.

Retiring coal plants: YES!!! So pleased about this.

Investing in solar: YES!!! Doubly pleased.

But building a new fracked gas plant? NO NO NO.

This is not the way forward. Natural gas is not sustainable, is not much better than coal, and only slows our much-needed transition to renewable energy sources that don't harm the planet. We can power MN without this new gas plant--please modify Xcel's plan to eliminate it.

Thank you.

Yes, Xcel Energy's IRP vision is a good plan. It will change in 5-10 years due to some of the following visionary grid drivers: 1. Area microgrids will become a part of the larger grid. Natural gas, diesel or fuel cells may be needed for backup generation. 2. The existing grid should still provide most of the power. This will come from wind, large grid and customer solar, nuclear, natural gas and other future G&T. Grid reliability and balance are the most important aspects, especially for cyber security, "locational value" grid planning and "transactive energy" grid design. 3.Coal and other higher cost electricity supply will phase out in 10-20 years. 4.Solar alone, without storage, could maximize out at 10%+ due to the duck curve. 5. Passive designed buildings and communities could lead to net-zero of self-contained islanded energy systems. Geothermal energy will play a part. 6. Storage before and behind the meter should become virtual power plants (VPP's) with bi-directional flow of energy. Both grid and customer solar fed. 7. Software management/control (bi-directional) flow of energy + storage should lead to customer energy purchase on demand through smart meters. (transactive energy). 8. Software + smart meters should help microgrid managers to sell negative power to customers who have available battery storage capacity, (transactive energy). 9. Small Modular Reactors (SMR's) should slowly replace large nuclear plants in increments of about 50MW to replace existing base load plants. 10. All-electric will become the most efficient means of energy transfer away from energy sources, i.e. coal, natural gas, bio-fuels even with AC - DC - AC transfer.

The plan should be modified to include more zero-carbon emissions renewable energy. We need to move our economy and energy generation away from carbon emissions sources as quickly as possible, and the current IRP does not seem to be moving quickly enough.
