What about propane for rural folks? Do we have to give up gas furnaces and stoves? Who will pay? Will electric bills go way up?

================================================================================

News that Colorado has set hard target dates for an end to burning natural gas in our daily lives prompted many “wait, what?” questions from Colorado Sun readers. And we are here to help.

The Public Utilities Commission approved a “Clean Heat Plan” that calls for the state’s natural gas utilities to cut emissions from delivering and burning natural gas by 41% in the next 10 years, and all natural gas emissions entirely by 2050. We talked to state regulators, clean energy officials and advocates, and consumer groups for answers to your most urgent questions.

Q: What about propane? Many rural and mountain Colorado homes have a propane tank. Must those homes convert to expensive electric heating, hot water and cooking appliances, and if so, who pays?

A: The newly approved plans do not cover propane tanks or propane distributors. They task the big utilities delivering natural gas to homes in pipelines with the mandate to hit the targets. That means Xcel, Atmos Energy and Black Hills Energy. Homes using existing propane tanks are not directly affected, though clean energy advocates still encourage those homeowners to seek rebates and other help in converting to more efficient electrical appliances that will be cheaper to operate.

Q: As a homeowner, do I have to do something about my gas appliances or furnace?

A: The new rules are not aimed at homeowners. They are requirements for the utilities. The utilities will be the ones planning internal changes and consumer and business incentives to both limit harmful methane leaks and convince people to switch to electric appliances. Utilities will still be delivering natural gas to consumers, but they must now start taking concrete steps toward gradually reducing use and emissions. If a utility believes it will take hundreds of millions of dollars in rebate incentives to get an adequate number of installed electric appliances, thereby cutting fossil fuel emissions, they would also have to get that spending and potential rate increases approved by the PUC. Under current rules, no one is showing up at your door to rip out a gas water heater against your will.

Q: If I am interested in making appliance changes but don’t have the capital to do it, can I get help?

A: Yes, from multiple sources. In fact, the Colorado Energy Office recently announced new rebates aimed at low- and middle-income households in mobile or manufactured homes. Each utility also has pools of money for rebates for electric appliances. Nonprofits and government agencies often have appliance and weatherization programs that can provide thousands of dollars for projects. The energy office recommends you start here.

Q: Won’t the transformation to all-electrical energy overwhelm current generating capacity, and also raise my electric bills?

A: Certainly the growth in electrical demands — from a host of new EVs plugged in, to giant power-sucking data centers for AI, to electric heat pumps and tankless water heaters — will put more strain on Colorado’s power generation. Utilities are moving to add more generating capacity. For now generation capacity is adequate but tight. That’s why when Xcel’s Comanche 3 coal-fired unit went down, the PUC approved keeping Unit 2 running even though it was supposed to close Dec. 31.

Some groups — not just environmental advocates, but businesses as well — question whether utilities are overstating electric demand, and whether they’ve properly managed the power plants they’ve already got. Expect more questions and more reports on whether the growth in solar and wind clean power sources can match growing demand.

As for rising costs?

“I think people have an assumption that if we’re adding new load to the electric system, that that is going to add a lot of cost. And in fact, that can be true, but it isn’t always true,” Colorado Energy Office director Will Toor said.

He cites studies showing that even without growth in electrical demand, there are fixed costs required in coming decades that would raise consumer electric rates. Those unavoidable costs include a vastly upgraded power line system throughout Colorado to link new solar and wind farms to the grid, as well as hardening transmission lines against growing wildfire risk. If demand is stagnant, then current consumers will have to pay those extra unavoidable costs. If demand grows in a planned and controlled way, Toor said, then the new consumers will help pay for those fixed costs and limit price increases for all.

Q: Can the electrical system handle the planned increase in demand if we give up fossil fuels for cars and homes?

A: It will take planning and growth of clean resources, but the demand news is not all bad, Toor explained. For example, people with EVs tend to plug their cars in the garage overnight, when overall electrical demand drops. Moreover, Colorado is currently a “summer peaking” state, meaning more demand spikes happen in high summer heat when people come home in the afternoon and turn the air conditioning on. If installation of electric home heat pumps and water heaters means more electrical demand in cold winter months, much of that capacity already existed for the summer spikes.

Spreading out the changeover from natural gas through 2035 and 2050 targets, Toor noted, means demand will grow more gradually.

“You still need to make some distribution level investments,” he said. “But when it comes to sort of the big transmission and generation, we’ve got excess capacity in the winter.”

Q: If everything in the Clean Heat plan is so reasonable, why did two state agencies want the timetable for the natural gas switchover to be less aggressive?

A: The PUC settled on a 41% target in cutting natural gas-related emissions by 2035. Environmental groups wanted at least 50% out of the system by then. The energy office and the Air Pollution Control Division, meanwhile, argued for a 30% target for the interim 2035 year.

“The 41% target, from our perspective, is a pretty challenging target for utilities. We certainly hope that utilities get there. I think we thought that 30% was probably more realistic,” Toor said. Reaching the more aggressive target may prompt the utilities to seek more rate increases to pay for their appliance rebates and system changes.

That said, Toor added, the PUC may have a more comprehensive view of cost pressures. Maintaining natural gas systems and extending them to new houses and buildings also require major investments from utilities, Toor noted. Environmental groups call those “stranded costs,” for example paying hundreds of millions of dollars for a pipeline to deliver less and less natural gas each year as the emissions cuts come into play. The utilities’ ability to now avoid those natural gas investments could free up money to pay for the switch to electricity.

“I’m confident that they will be able to strike the appropriate balance going forward,” Toor said.

Our central stove is a Vermont Castings Defiant model. I once made a beef stew on it, cooked slow all day, and it was delicious. And when the power goes out in the dead of winter, it’s a blessing.

Propane: Yes, natural gas: No
Electric: ridiculous

You don’t want to be in position that GOVT can shut you off.
You control your own tank (s).
LNG and Electric all have switches out of your control.

I recall watching the ‘peaceful assemblies’ protesting ‘Nam from the rooftop of my boarding house on the hill one night. The Nat’l Guard was launching white flares to light up the crowds and tear gas to disperse them. Rumors were things like ‘Berkeley just took the Bay Bridge’ and stuff about Madison. It was as if there was competition for stupid. SDS was around.

I’m 75 and still cutting, hauling, splitting and stacking. I have 6 cords of dry seasoned oak and hickory stacked. I was very fortunate this year since about 2 acres of woods were cleared for building a house and I got all of the wood that was not sold for lumber, about half of what was cut. The tree service had to get rid of the logs that the mill won’t buy, and the building lot was only 1/4 mile away. The guys delivered it onto our property for free. Well, not really, 2 cases of beer. We probably have a dozen cords in addition to the 6 cords split and stacked. I won’t have to get firewood for the next 4 or 5 years.

It is easy to convert to electricity.

Just connect some 10K voltage to the natural gas supply lines.

The lines are already there, and connect directly to the houses.

This actually makes more sense than their plan.

Considering that CO gets most of its power from a coal burning plant, this is not going to end well.

SW Colorado has lots of gas wells. This sounds as if the Californication of Colorado has taken place.
Now they are trying to shut down the New Mexico oil, gas and mining industry.

We had a big ice storm here several years ago. Electricity was down for days. But WE were on natural gas so had plenty of heat. On city water and had water. We did well with oil lamps and Coleman lamps till the power came back on.

So true. Leftist are doing the same idiotic thing the communists did in every country they subdue. They genuinely want a large portion of the population to freeze to death and the remaining ones to beg to them for heat. Same for food supplies.

Heat pumps have outdoor temp problems and are expensive. Much more than a simple gas furnace. Then there is hot water.

We’ve had winter power outages. A very small generator can keep a large home warm with gas heat.

And now they’re targeting Texas, Tennessee, North Carolina, and South Carolina as a sort of leftists fascists firewall. Once those are fully secure, they will push east and southward and destroy what is left the booming Southern states.
