Waste Management already generates renewable energy by incinerating trash and converting methane from its miles of landfills.

Now the company is wading into a new venture that can turn garbage into synthetic gas for heating, ethanol or electricity. The move also gets Waste Management closer to its goals of doubling renewable energy production by 2020 and investing in new waste technologies.

Houston-based Waste Management and InEnTec LLC have formed a 50-50 joint venture developing plasma gasification facilities to process waste. The joint venture, called S4 Energy Solutions, will use InEnTecÂ’s Plasma Enhanced Melter technology, while Waste Management will offer its waste collection and management expertise. As the technologyÂ’s name suggests, an electricity-conducting gas known as plasma heats the waste to between 10,000 and 20,000 degrees Fahrenheit, which transforms the garbage into synthetic gas, also called syngas.

InEnTec's Plasma Enhanced Melter technology will begin processing industrial byproducts at Dow Corning's Midland, Mich., facility in late 2009.

The syngas can be converted to electricity, diesel or ethanol, a natural gas substitute, or industrial products such as hydrogen or methanol.

The technology can process several types of waste, including radioactive and old tires, but the venture will begin with medical and other commercial and industrial wastes because they are of “high-energy value” and can produce renewable fuels, products and possibly energy.

S4 Energy Solutions also will work to make the technology both economical and scalable in order to one-day process municipal solid waste.

The technology is being used in Japan, Taiwan, and Richland, Va.; a plant at a Michigan-based Dow Corning facility is now under construction.

Toronto Power Outages Persist for Hundreds After Spring Storm

Toronto Hydro Storm Outages continue after strong winds and heavy rain, with crews restoring power, clearing debris and downed lines. Safety alerts and real-time updates guide affected neighborhoods via website and social media.

 

Key Points

Toronto Hydro Storm Outages are weather-related power cuts; crews restore service safely and share public updates.

✅ Crews prioritize areas with severe damage and limited access

✅ Report downed power lines; keep a safe distance

✅ Check website and social media for restoration updates

 

In the aftermath of a powerful spring storm that swept through Toronto on Tuesday, approximately 400 customers remain without power as of Sunday. The storm, which brought strong winds and heavy rain that caused severe flooding in some areas, led to significant damage across the city, including downed trees and power lines. Toronto Hydro crews have been working tirelessly to restore service, similar to efforts by Sudbury Hydro crews in Northern Ontario, focusing on areas with the most severe damage. While many customers have had their power restored, the remaining outages are concentrated in neighborhoods where access is challenging due to debris and fallen infrastructure.

Toronto Hydro has assured residents that restoration efforts are ongoing and that they are prioritizing safety and efficiency, in step with recovery from damaging storms in Ontario across the province. The utility company has urged residents to report any downed power lines and to avoid approaching them, as they may still be live and dangerous, and notes that utilities sometimes rely on mutual aid deployments to speed restoration in large-scale events. Additionally, Toronto Hydro has been providing updates through their website and social media channels, keeping the public informed about the status of power restoration in affected areas.

The storm's impact has also led to disruptions in other services, and power outages in London disrupted morning routines for thousands earlier in the week. Some public transportation routes experienced delays due to debris on tracks, and several schools in the affected areas were temporarily closed. City officials are coordinating with various agencies to address these issues and ensure that services return to normal as quickly as possible, even as Quebec contends with widespread power outages after severe windstorms.

Residents are advised to stay updated on the situation through official channels and to exercise caution when traveling in storm-affected areas. Toronto Hydro continues to work diligently to restore power to all customers and appreciates the public's patience during this challenging time, a challenge echoed when Texas utilities struggled to restore power during Hurricane Harvey.

Hydro One and Alectra announce major investments to strengthen electricity infrastructure and improve local reliability in the Hamilton area

Hydro One and Alectra Hamilton Grid Upgrades will modernize electricity infrastructure with new transformers, protection devices, transmission and distribution improvements, tree trimming, pole replacements, and line refurbishments to boost reliability and reduce outages across region.

 

Key Points

A $250M plan to modernize Hamilton transmission and distribution, reducing outages and improving reliability by 2022.

✅ New transformers and protection devices to cut outages

✅ Refurbished 1915 line powering Hamilton West Mountain

✅ Tree trimming and pole replacements across 1,260 km

 

Hydro One Networks Inc. (Hydro One), Ontario's largest electricity transmission and distribution company whose delivery rates recently increased, and Alectra Utilities have announced they expect to complete approximately $250 million of work in the Hamilton area by 2022 to upgrade local electricity infrastructure and improve service reliability.

As part of these plans to strengthen the electricity grid in the Hamilton region, where utilities must adapt to climate change pressures, investments are expected to include:

installing quieter, more efficient transformers in four stations across Hamilton to assist in reducing the number of outages;
replacing protection and switching devices across the city to shorten outage restoration times, reflecting how transmission line work underpins reliability;
refurbishing a power line originally installed in 1915 that is critical to powering the Hamilton West Mountain area; and,
trimming hazardous trees across more than 1,260 km of overhead powerlines and replacing more than 270 poles.
Hydro One will be working with Alectra Utilities to replace aging infrastructure at Elgin transmission station.

"A loss of power grinds life to a halt, impacting businesses, families and productivity. That's why Hydro One is partnering with Alectra Utilities to support a growing local economy in Hamilton, while improving power reliability for its residents," said Jason Fitzsimmons, Chief Corporate Affairs and Customer Care Officer. "Replacing aging infrastructure and modernizing equipment is part of our plan to build a stronger, safer and more reliable electricity system for Ontario now and into the future." 

"Partnering with Hydro One to invest in our local community will create a safer, more resilient and reliable system for the future," said Max Cananzi, President, Alectra Utilities.  "In addition to investments in the transmission system, Alectra Utilities also plans to invest $235 million over the next five years to renew, upgrade and connect customers to the electrical distribution and supporting systems in Hamilton. Investments in the transmission and distribution systems in Hamilton will contribute to the long-term sustainability of our communities."

"I am pleased to see Hydro One and Alectra investing in modernizing local electricity infrastructure and improving reliability," said Member of Provincial Parliament, Donna Skelly.  "Safe and reliable power is essential to supporting local families, businesses and our community."

Across Ontario, First Nations call for action on urgently needed transmission lines highlight the importance of timely grid investments.

Hydro One's investments included in this announcement are captured in its previously disclosed future capital expenditures, amid proposed projects like the Meaford hydro project across Ontario.

Much of Hydro One's electricity system was built in the 1950s, and replacing aging assets is critical as delays affecting a cross-border transmission line elsewhere have shown. Its three-year, $5 billion investment plan supports safe and reliable power to communities across Ontario, and strong regulatory oversight illustrated by the ATCO Electric penalty helps maintain public trust.

Tackling climate change with machine learning: Covid-19 and the energy transition

Covid-19 Energy Transition and Machine Learning reshape climate change policy, electricity planning, and grid operations, from demand forecasting and decarbonization strategies in Europe to scalable electrification modeling and renewable integration across Africa.

 

Key Points

How the pandemic reshapes energy policy and how ML improves planning, demand forecasts, and grid reliability in Africa.

✅ Pandemic-driven demand shifts strain grid operations and markets

✅ Policy momentum risks rollback; favor future-oriented decarbonization

✅ ML boosts demand prediction, electrification, and grid reliability in Africa

 

The impact of Covid-19 on the energy system was discussed in an online climate change workshop that also considered how machine learning can help electricity planning in Africa.

This year’s International Conference on Learning Representations event included a workshop held by the Climate Change AI group of academics and artificial intelligence industry representatives, which considered how machine learning can help tackle climate change and highlighted advances by European electricity prediction specialists working in this field.

Bjarne Steffen, senior researcher at the energy politics group at ETH Zürich, shared his insights at the workshop on how Covid-19 and the accompanying economic crisis are affecting recently introduced ‘green’ policies. “The crisis hit at a time when energy policies were experiencing increasing momentum towards climate action, especially in Europe, and in proposals to invest in smarter electricity infrastructure for long-term resilience,” said Steffen, who added the coronavirus pandemic has cast into doubt the implementation of such progressive policies.

The academic said there was a risk of overreacting to the public health crisis, as far as progress towards climate change goals was concerned.

 

Lobbying

“Many interest groups from carbon-intensive industries are pushing to remove the emissions trading system and other green policies,” said Steffen. “In cases where those policies are having a serious impact on carbon-emitting industries, governments should offer temporary waivers during this temporary crisis, instead of overhauling the regulatory structure.”

However, the ETH Zürich researcher said any temptation to impose environmental conditions to bail-outs for carbon-intensive industries should be resisted. “While it is tempting to push a green agenda in the relief packages, tying short-term environmental conditions to bail-outs is impractical, given the uncertainty in how long this crisis will last,” he said. “It is better to include provisions that will give more control over future decisions to decarbonize industries, such as the government taking equity shares in companies.”

Steffen shared with pv magazine readers an article published in Joule which can be accessed here, and which articulates his arguments about how Covid-19 could affect the energy transition.

 

Covid-19 in the U.K.

The electricity system in the U.K. is also being affected by Covid-19, even as the U.S. electric grid grapples with climate risks, according to Jack Kelly, founder of London-based, not-for-profit, greenhouse gas emission reduction research laboratory Open Climate Fix.

“The crisis has reduced overall electricity use in the U.K.,” said Kelly. “Residential use has increased but this has not offset reductions in commercial and industrial loads.”

Steve Wallace, a power system manager at British electricity system operator National Grid ESO recently told U.K. broadcaster the BBC electricity demand has fallen 15-20% across the U.K. The National Grid ESO blog has stated the fall-off makes managing grid functions such as voltage regulation more challenging.

Open Climate Fix’s Kelly noted even events such as a nationally-coordinated round of applause for key workers was followed by a dramatic surge in demand, stating: “On April 16, the National Grid saw a nearly 1 GW spike in electricity demand over 10 minutes after everyone finished clapping for healthcare workers and went about the rest of their evenings.”

Climate Change AI workshop panelists also discussed the impact machine learning could have on improving electricity planning in Africa. The Electricity Growth and Use in Developing Economies (e-Guide) initiative funded by fossil fuel philanthropic organization the Rockefeller Foundation aims to use data to improve the planning and operation of electricity systems in developing countries.

E-Guide members Nathan Williams, an assistant professor at the Rochester Institute of Technology (RIT) in New York state, and Simone Fobi, a PhD student at Columbia University in NYC, spoke about their work at the Climate Change AI workshop, which closed on Thursday. Williams emphasized the importance of demand prediction, saying: “Uncertainty around current and future electricity consumption leads to inefficient planning. The weak link for energy planning tools is the poor quality of demand data.”

Fobi said: “We are trying to use machine learning to make use of lower-quality data and still be able to make strong predictions.”

The market maturity of individual solar home systems and PV mini-grids in Africa mean more complex electrification plan modeling is required, similar to integrating AI data centers into Canada's grids at scale.

 

Modeling

“When we are doing [electricity] access planning, we are trying to figure out where the demand will be and how much demand will exist so we can propose the right technology,” added Fobi. “This makes demand estimation crucial to efficient planning.”

Unlike many traditional modeling approaches, machine learning is scalable and transferable. Rochester’s Williams has been using data from nations such as Kenya, which are more advanced in their electrification efforts, to train machine learning models to make predictions to guide electrification efforts in countries which are not as far down the track.

Williams also discussed work being undertaken by e-Guide members at the Colorado School of Mines, which uses nighttime satellite imagery and machine learning to assess the reliability of grid infrastructure in India, where new algorithms to prevent ransomware-induced blackouts are also advancing.

 

Rural power

Another e-Guide project, led by Jay Taneja at the University of Massachusetts, Amherst – and co-funded by the Energy and Economic Growth program on development spending based at Berkeley – uses satellite imagery to identify productive uses of electricity in rural areas by detecting pollution signals from diesel irrigation pumps.

Though good quality data is often not readily available for Africa, Williams added, it does exist.

“We have spent years developing trusting relationships with utilities,” said the RIT academic. “Once our partners realize the value proposition we can offer, they are enthusiastic about sharing their data … We can’t do machine learning without high-quality data and this requires that organizations can effectively collect, organize, store and work with data. Data can transform the electricity sector, as shown by Canadian projects to use AI for energy savings, but capacity building is crucial.”

Hydro Quebec to increase hydropower capacity to more than 37,000 MW in 2021

Hydro Quebec transmission expansion aims to move surplus hydroelectric capacity from record reservoirs to the US grid via new interties, increasing exports to New England and New York amid rising winter peak demand.

 

Key Points

A plan to add capacity and intertie links to export surplus hydro power from Quebec's reservoirs to the US grid.

✅ 245 MW added in 2021; portfolio reaches 37,012 MW

✅ Reservoirs at unprecedented levels; export potential high

✅ Lacks US transmission; working on new interties

 

Hydro Quebec plans to add an incremental 245 MW of hydro-electric generation capacity in 2021 to its expansive portfolio in the north of the province, while Quebec authorized nearly 1,000 MW for industrial projects across the region, bringing the total capacity to 37,012 MW, an official said Friday

Quebec`s highest peak demand of 39,240 MW occurred on January 22, 2014.

A little over 75% of Quebec`s population heat their homes with electricity, Sutherland said, aligning with Hydro Quebec's strategy to wean the province off fossil fuels over time.

The province-owned company produced 205.1 TWh of power in 2017 and its net exports were 34.4 TWh that year, while Ontario chose not to renew a power deal in a separate development.

Sutherland said Hydro Quebec`s reservoirs are currently at "unprecedented levels" and the company could export more of its electricity to New England and New York, but faces transmission constraints that limit its ability to do so.

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, Sutherland said.

Separately, NB Power signed three deals to bring more Quebec electricity into the province, reflecting growing regional demand.

The last major intertie connection between Quebec and the US was completed close to 30 years ago. The roughly 2,000 MW capacity transmission line that connects into the Boston area was completed in the late 1990s, according to Hydro Quebec spokeswoman Lynn St-Laurent.

High Natural Gas Prices Make This The Time To Build Back Better - With Clean Electricity

Build Back Better Act Energy Savings curb volatile fossil fuel heating bills by accelerating electrification and renewable electricity, insulating households from natural gas, propane, and oil price spikes while cutting emissions and lowering energy costs.

 

Key Points

BBBA policies expand clean power and electrification to curb volatility, lower bills, and cut emissions.

✅ Tax credits for renewables, EVs, and efficient all-electric homes

✅ Shields households from natural gas, propane, and heating oil spikes

✅ Cuts methane, lowers bills, and improves grid reliability and jobs

 

Experts are forecasting serious sticker shock from home heating bills this winter. Nearly 60 percent of United States’ households heat their homes with fossil fuels, including natural gas, propane, or heating oil, and these consumers are expected to spend much more this winter because of fuel price increases.

That could greatly burden many families and businesses already operating on thin margins. Yet homes that use electricity for heating and cooking are largely insulated from the pain of volatile fuel markets, and they’re facing dramatically lower price increases as a result.

Projections say cost increases for households could range anywhere from 22% to 94% more, depending on the fuel used for heating and the severity of the winter temperatures. But the added expenditures for the 41% of U.S. households using electricity for heating are much less stark—these consumers will see only a 6% price increase on average. The projected fossil fuel price spikes are largely due to increased demand, limited supply, declining fuel stores, and shifting investment priorities in the face of climate change.

The fossil fuel industry is already seizing this moment to use high prices to persuade policymakers to vote against clean energy policies, particularly the Build Back Better Act (BBBA). Spokespeople with ties to the fossil fuel industry and some consumer groups are trying to pin higher fuel prices on the proposed legislation even before it has passed, even as analyses show the energy crisis is not spurring a green revolution on its own, let alone begun impacting fuel markets. But the claim the BBBA would cost Americans and the economy is false.

The facts tell a different story. Adopting smart climate policies and accelerating the clean energy transition are precisely the solutions to counter this vicious cycle by ending our dependance on volatile fossil fuels. The BBBA will ensure reliable, affordable clean electricity for millions of Americans, in line with a clean electricity standard many experts advocate—a key strategy for avoiding future vulnerability. Unlike fossil fuels subject to the whims of a global marketplace, wind and sunshine are always free. So renewable-generated electricity comes with an ultra-low fixed price decades into the future.

By expanding clean energy and electric vehicle tax credits, creating new incentives for efficient all-electric homes, and dedicating new funding for state and local programs, the BBBA provides practical solutions that build on lessons from Biden's climate law to protect Americans from price shocks, save consumers money, and reduce emissions fueling dangerous climate change.


What’s really causing the gas price spikes?
The U.S. Energy Information Administration’s winter 2021 energy price forecasts project that homes heated with natural gas, fuel oil, and propane will see average price increases of 30%, 43%, and 54%, respectively. Those who heat their homes with electricity, on the other hand, should expect a modest 6% increase. At the pump, drivers are seeing some of the highest gas prices in nearly a decade as the U.S. energy crisis ripples through electricity, gas, and EV markets today. And the U.S. is not alone. Countries around the globe are experiencing similar price jumps, including Britain's high winter energy costs this season.

A closer look confirms the cause of these high prices is not clean energy or climate policies—it’s fossil fuels themselves.  

First, the U.S. (and the world) are just now feeling the effects of the oil and gas industry’s reduced fuel production and spending due to the pandemic. COVID-19 brought the world’s economies to a screeching halt, and most countries have not returned to pre-COVID economic activity. During the past 20 months, the oil and gas industry curtailed its production to avoid oversupply as demand fell to all-time lows. Just as businesses were reopening, stored fuel was needed to meet high demand for cooling during 2021’s hottest summer on record, driving sky-high summer energy bills for many households. February’s Texas Big Freeze also disrupted gas distribution and production.

The world is moving again and demand for goods and services is rebounding to pre-pandemic levels. But even with higher energy demand, OPEC announced it would not inject more oil into the economy. Major oil companies have also held oil and gas spending flat in 2021, with their share of overall upstream spending at 25%, compared with nearly 40% in the mid-2010s. And as climate change threats loom in the financial world, investors are reducing their exposure to the risks of stranded assets, increasingly diversifying and divesting from fossil fuels. 

Second, despite strong and sustained growth for renewable energy, energy storage, and electric vehicles, the relatively slow pace to adopt fossil fuel alternatives at scale has left U.S. households and businesses tethered to an industry well-known for price volatility. Today, some oil drillers are using profits from higher gas prices to pay back debt and reward shareholders as demanded by investors, instead of increasing supply. Rising prices for a limited commodity in high demand is generating huge profits for many of the world’s largest companies at the expense of U.S. households.

Because 48% of homes use fossil gas for heating and another 10% heat with propane and fuel oil, more than half of U.S. households will feel the impact of rising prices on their home energy bills. One in four U.S. households continues to experience a high energy burden (meaning their energy expenses consume an inordinate amount of their income), including risks of pandemic power shut-offs that deepen energy insecurity, and many are still experiencing financial hardships exacerbated by the pandemic. Those with inefficient fossil-fueled appliances, homes, and cars will be hardest hit, and many families with fixed- and lower-incomes could be forced to choose between heat or other necessities.

We have the solutions—the BBBA will unlock their benefits for all households

Short-term band-aids may be enticing, but long-term policies are the only way out of this negative feedback loop. Clean energy and building electrification will prevent more costly disasters in the future, but they’re the very solutions the fossil fuel industry fights at every turn. All-electric homes and vehicles are a natural hedge against the price spikes we’re experiencing today since renewables are inherently devoid of fuel-related price fluctuations.

RMI analysis shows all-electric single-family homes in all regions of the country have lower energy bills than a comparable mixed fuel-homes (i.e., electricity and gas). Electric vehicles also save consumers money. Research from University of California, Berkeley and Energy Innovation found consumers could save a total of $2.7 trillion in 2050—or $1,000 per year, per household for the next 30 years—if we accelerate electric vehicle deployment in the coming decade.

The BBBA would help deliver these consumer savings by expanding and expediting clean energy, while ensuring equitable adoption among lower-income households and underserved communities. Extending and expanding clean energy tax credits; new incentives for electric vehicles (including used electric vehicles); and new incentives for energy efficient homes and all-electric appliances (and electrical upgrades) will reduce up-front costs and spur widespread adoption of all-electric homes, buildings, and cars.

A combination of grants, incentives, and programs will promote private sector investments in a decarbonized economy, while also funding and supporting state and local governments already leading the way. The BBBA also allocates dedicated funding and makes important modifications (such as higher rebate amounts and greater point-of-purchase availability) to ensure these technologies are available to low-income households, underserved urban and rural communities, tribes, frontline communities, and people living in multifamily housing.

Finally, the BBBA proposes to make oil and gas polluters pay for the harm they are causing to people’s health and the climate through a methane fee. This fee would cost companies less than 1% of their revenue, meaning the industry would retain over 99% of its profits. In return return we’d see substantial reductions of a powerful greenhouse gas and a healthier environment in communities living near fossil fuel production. These benefits also come with a stronger economy—Energy Innovation analysis shows the methane fee would create more than 70,000 jobs by 2050 and boost gross domestic product more than $250 billion from 2023 to 2050.

The facts speak for themselves. Gas prices are rising because of reasons totally unrelated to smart climate and clean energy policies, which research shows actually lower costs. For the first time in more than a decade, America has the opportunity to enact a comprehensive energy policy that will yield measurable savings to consumers and free us from oil and gas industry control over our wallets.

The BBBA will help the U.S. get off the fossil fuel rollercoaster and achieve a stable energy future, ensuring that today’s price spikes will be a thing of the past. Proving, once and for all, that the solution to our fossil fuel woes is not more fossil fuels.

California electricity pricing changes pose an existential threat to residential rooftop solar

California Rooftop Solar Rate Reforms propose shifting net metering to fixed access fees, peak-demand charges, and time-of-use pricing, aligning grid costs, distributed generation incentives, and retail rates for efficient, least-cost electricity and fair cost recovery.

 

Key Points

Policies replacing net metering with fixed fees, demand charges, and time-of-use rates to align costs and incentives.

✅ Large fixed access charge funds grid infrastructure

✅ Peak-demand pricing reflects capacity costs at system peak

✅ Time-varying rates align marginal costs and emissions

 

The California Public Service Commission has proposed revamping electricity rates for residential customers who produce electricity through their rooftop solar panels. In a recent New York Times op‐​ed, former Governor Arnold Schwarzenegger argued the changes pose an existential threat to residential rooftop solar. Interest groups favoring rooftop solar portray the current pricing system, often called net metering, in populist terms: “Net metering is the one opportunity for the little guy to get relief, and they want to put the kibosh on it.” And conventional news coverage suggests that because rooftop solar is an obvious good development and nefarious interests, incumbent utilities and their unionized employees, support the reform, well‐​meaning people should oppose it. A more thoughtful analysis would inquire about the characteristics and prices of a system that supplies electricity at least cost.

Currently, under net metering customers are billed for their net electricity use plus a minimum fixed charge each month. When their consumption exceeds their home production, they are billed for their net use from the electricity distribution system (the grid) at retail rates. When their production exceeds their consumption and the excess is supplied to the grid, residential consumers also are reimbursed at retail rates. During a billing period, if a consumer’s production equaled their consumption their electric bill would only be the monthly fixed charge.

Net metering would be fine if all the fixed costs of the electric distribution and transmission systems were included in the fixed monthly charge, but they are not. Between 66 and 77 percent of the expenses of California private utilities do not change when a customer increases or decreases consumption, but those expenses are recovered largely through charges per kWh of use rather than a large monthly fixed charge. Said differently, for every kWh that a PG&E solar household exported into the grid in 2019, it saved more than 26 cents, on average, while the utility’s costs only declined by about 8 cents or less including an estimate of the pollution costs of the system’s fossil fuel generators. The 18‐​cent difference pays for costs that don’t change with variation in a household’s consumptions, like much of the transmission and distribution system, energy efficiency programs, subsidies for low‐​income customers, and other fixed costs. Rooftop solar is so popular in California because its installation under a net metering system avoids the 18 cents, creating a solar cost shift onto non-solar customers. Rooftop solar is not the answer to all our environmental needs. It is simply a form of arbitrage around paying for the grid’s fixed costs.

What should electricity tariffs look like? This article in Regulation argues that efficient charges for electricity would consist of three components: a large fixed charge for the distribution and transmission lines, meter reading, vegetation trimming, etc.; a peak‐​demand charge related to your demand when the system’s peak demand occurs to pay for fixed capacity costs associated with peak use; and a charge for electricity use that reflects the time‐ and location‐​varying cost of additional electricity supply.

Actual utility tariffs do not reflect this ideal because of political concerns about the effects of large fixed monthly charges on low‐​income customers and the optics of explaining to customers that they must pay 50 or 60 dollars a month for access even if their use is zero. Instead, the current pricing system “taxes” electricity use to pay for fixed costs. And solar net metering is simply a way to avoid the tax. The proposed California rate reforms would explicitly impose a fixed monthly charge on rooftop solar systems that are also connected to the grid, a change that could bring major changes to your electric bill statewide, and would thus end the fixed‐​cost avoidance. Any distributional concerns that arise because of the effect of much larger fixed charges on lower‐​income customers could be managed through explicit tax deductions that are proportional to income.

The current rooftop solar subsidies in California also should end because they have perverse incentive effects on fossil fuel generators, even as the state exports its energy policies to neighbors. Solar output has increased so much in California that when it ends with every sunset, natural gas generated electricity has to increase very rapidly. But the natural gas generators whose output can be increased rapidly have more pollution and higher marginal costs than those natural gas plants (so called combined cycle plants) whose output is steadier. The rapid increase in California solar capacity has had the perverse effect of changing the composition of natural gas generators toward more costly and polluting units.

The reforms would not end the role of solar power. They would just shift production from high‐​cost rooftop to lower‐​cost centralized solar production, a transition cited in analyses of why electricity prices are soaring in California, whose average costs are comparable with electricity production in natural gas generators. And they would end the excessive subsidies to solar that have negatively altered the composition of natural gas generators.

Getting prices right does not generate citizen interest as much as the misguided notion that rooftop solar will save the world, and recent efforts to overturn income-based utility charges show how politicized the debate remains. But getting prices right would allow the decentralized choices of consumers and investors to achieve their goals at least cost.
