South Korea plans to address future power demand by going greener and lowering power consumption.

Having set a 2030 deadline to reduce emissions of greenhouse gases by 30, the country is in a state of flux. The government of South Korea is promoting the development of clean, alternative and renewable energies through a $36 billion, five-year plan that is already directly affecting domestic power policies.

New plans are pushing power companies to increase the number of district heating users between now and 2014. Combined heat and power CHP plants are common throughout South Korea and are generally associated with district heating. Not only do they help cut costs in terms of heating, but also supply electricity to local grids. Currently, about 13 of South Korea's 14 million households rely on district heating and CHP plants. The government is seeking to raise the number of households using district heating by at least one-third by 2014.

Korea District Heating Corporation KDHC serves almost 60 of all homes that use district heating in South Korea and plans to increase this customer base to 2 million by 2015. With plans to incorporate government-backed district-cooling research within the next few years, KDHC stands to benefit greatly from the increase in CHP plants.

Officials have mentioned that as South Korea looks to combat the looming electricity crunch, more and more existing power plants may be transformed into CHP plants. The majority of electricity costs are associated with the heating and cooling of homes. South Korea hopes to reduce the use of electricity for temperature control by directly supplying warm and cool air. The government is fully in support of district cooling research and hopes that it is incorporated into CHP plants the near future.

The call for more combined heat and power plants parallels South Korea's switch to natural gas in the country's coal-dominated market. Natural gas burns cleaner than coal and is generally the fuel of choice in CHP plants. A natural gas-fired CHP that is capable of supplying about 325 megawatts MW of electricity and more than 300 gigacalories per hour of steam to the local grid, such as the one KDHC is planning to construct in 2013, generally costs about $550 million. A coal-fired CHP plant, although capable of generating more electricity and steam for less money, emits twice as much carbon dioxide per unit of energy as a natural gas-fired plant.

Although the government is pushing for an increase in CHP plants, it is also demanding more renewable energy projects. KDHC will invest an additional $41 million in solar and wind power research in the coming years to prepare for the government's demands for increased renewable energy.

Newsom Vetoes Bill to Codify Load Flexibility

California Governor Gavin Newsom vetoed a bill aimed at expanding load flexibility in state grid planning, citing conflicts with California’s resource adequacy framework and concerns over grid reliability and energy planning uncertainty.

 

Why has Newsom vetoed the Bill to Codify Load Flexibility?

Governor Gavin Newsom’s veto blocks legislation that would have required the California Energy Commission to incorporate load flexibility into the state’s energy planning and policy framework, a move that has stirred debate across the clean energy sector.

✅ Argues the bill conflicts with California’s existing Resource Adequacy system

✅ Draws backlash from clean energy and grid modernization advocates

✅ Exposes ongoing tension over how to manage renewable integration and demand response

 

California Governor Gavin Newsom has vetoed Assembly Bill 44, which would have required the California Energy Commission to evaluate and incorporate load management mechanisms into the state’s energy planning process. The move drew criticism from clean energy advocates who say it undermines efforts to strengthen grid reliability and reduce costs.

The bill directed the commission to adopt “upfront technical requirements and load modification protocols” that would allow load-serving entities to adjust their electrical demand forecasts. Proponents viewed this as a way to modernize California’s grid management, and to explore a revamp of electricity rates to help clean the grid, making it more responsive to demand fluctuations and renewable energy variability.

In his veto statement, Newsom said the bill was incompatible with existing energy planning frameworks, even as a looming electricity shortage remains a concern. “While I support expanding electric load flexibility, this bill does not align with the California Public Utility Commission’s Resource Adequacy framework,” he said. “As a result, the requirements of this bill would not improve electric grid reliability planning and could create uncertainty around energy resource planning and procurement processes.”

Newsom’s decision comes shortly after he signed a broad package of energy legislation that set the stage for a regional Western electricity market and extended the state’s cap-and-trade program. However, that legislative package did not include continued funding for several key grid reliability programs — including what advocates have called the world’s largest virtual power plant, a distributed network of connected devices that can balance electricity demand in real time.

Clean energy supporters saw AB 44 as a crucial step toward integrating these distributed energy resources into long-term grid planning. “With Assembly Bill 44 being vetoed, the state has missed a huge opportunity to advance common-sense policy that would have lowered costs, strengthened the grid, and unlocked the full potential of advanced energy,” said Edson Perez, California lead at Advanced Energy United.

Perez added that the setback increases pressure on lawmakers to take stronger action in the next legislative session. “The pressure is on next session to ensure that California is using all tools in its policy toolbox to build critically needed infrastructure, strengthen the grid, and bring costs down,” he said.

California’s growing use of demand response programs and virtual power plants has been central to its strategy for managing grid stress during heat waves and wildfire seasons. These systems allow utilities and customers to temporarily reduce or shift energy use, helping to prevent blackouts and reduce the need for fossil-fuel peaker plants during peak demand.

A recent report by the Brattle Group found that California’s taxpayer-funded virtual power plant could save ratepayers $206 million between 2025 and 2028 while reducing reliance on gas generation. The study, commissioned by Sunrun and Tesla Energy, highlighted the potential for flexible load management to improve both grid reliability and reduce costs, even as regulators weigh whether the state needs more power plants to ensure reliability.

Despite these findings, Newsom’s veto signals continued tension between state policymakers and clean energy advocates over how best to modernize California’s power grid. While the governor has prioritized large-scale renewable development and regional market integration, critics argue that California’s climate policy choices risk exacerbating reliability challenges and that failing to codify load flexibility could slow progress toward a more adaptive, resilient, and affordable clean energy future.

American Households Struggle with Sky-High Energy Bills During Extreme Summer Heat

US Summer Energy Bills Crisis is driven by record heatwaves, soaring electricity prices, AC cooling demand, energy poverty risks, and LIHEAP relief, straining low-income households, vulnerable seniors, and budgets amid volatile utilities and peak demand.

 

Key Points

Rising household energy costs from extreme heat, higher electricity prices, and AC demand, straining vulnerable families.

✅ Record heatwaves drive peak electricity and cooling loads

✅ Tiered rates and volatile markets inflate utility bills

✅ LIHEAP aid and cooling centers offer short-term relief

 

As the sweltering heat of summer continues to grip much of the United States, American households are grappling with a staggering rise in energy bills. The combination of record-breaking temperatures and rising electricity prices is placing an unprecedented financial strain on families, raising concerns about the long-term impact on household budgets and overall well-being.

Record Heat and Energy Consumption

This summer has witnessed some of the hottest temperatures on record across the country. With many regions experiencing prolonged heatwaves, the demand for air conditioning and cooling systems has surged amid unprecedented electricity demand across parts of the U.S. The increased use of these energy-intensive appliances has led to a sharp rise in electricity consumption, which, combined with elevated energy prices, has pushed household energy bills to new heights.

The situation is particularly dire for households that are already struggling financially. Many families are facing energy bills that are not only higher than usual but are reaching levels that are unsustainable, underscoring electricity struggles for thousands of families across the country. This has prompted concerns about the potential for energy poverty, where individuals are forced to make difficult choices between paying for essential services and covering other necessary expenses.

Impact on Low-Income and Vulnerable Households

Low-income households and vulnerable populations are disproportionately affected by these soaring energy costs. For many, the financial burden of high energy bills is compounded by energy insecurity during the pandemic and other economic pressures, such as rising food prices and stagnant wages. The strain of paying for electricity during extreme heat can lead to tough decisions, including cutting back on other essential needs like healthcare or education.

Moreover, the heat itself poses a serious health risk, particularly for the elderly, children, and individuals with pre-existing health conditions. High temperatures can exacerbate conditions such as cardiovascular and respiratory illnesses, making the need for reliable cooling even more critical. For those struggling to afford adequate cooling, the risk of heat-related illnesses and fatalities increases significantly.

Utilities and Energy Pricing

The sharp rise in energy bills can be attributed to several factors, including higher costs of electricity production and distribution. The ongoing transition to cleaner energy sources, while necessary for long-term environmental sustainability, has introduced short-term volatility in energy markets. Additionally, power-company supply chain crises and increased demand during peak summer months have contributed to higher prices.

Utilities are often criticized for their pricing structures, which can be complex and opaque. Some regions, including areas where California electricity bills soar under scrutiny, use tiered pricing models that charge higher rates as energy consumption increases. This can disproportionately impact households that need to use more energy during extreme heat, further exacerbating financial strain.

Government and Community Response

In response to the crisis, various government and community initiatives are being rolled out to provide relief. Federal and state programs aimed at assisting low-income households with energy costs are being expanded. These programs, such as the Low-Income Home Energy Assistance Program (LIHEAP), offer financial assistance to help with utility bills, but demand often outstrips available resources.

Local community organizations are also stepping in to offer support. Initiatives include distributing fans and portable air conditioners, providing temporary cooling centers, and offering financial assistance to help cover energy costs. These efforts are crucial in helping to mitigate the immediate impact of high energy bills on vulnerable households.

Long-Term Solutions and Sustainability

The current crisis highlights the need for long-term solutions to address both the causes and consequences of high energy costs. Investing in energy efficiency and renewable energy technologies can help reduce the overall demand for electricity and lower long-term costs. Improvements in building insulation, the adoption of energy-efficient appliances, and advancements in smart grid technologies to prevent summer power outages are all essential components of a sustainable energy future.

Furthermore, addressing income inequality and supporting economic stability are critical to ensuring that all households can manage their energy needs without facing financial hardship. Policymakers will need to consider a range of strategies, including financial support programs, regulatory reforms, and infrastructure investments, to create a more equitable and resilient energy system.

Conclusion

As American households endure the double burden of extreme summer heat and skyrocketing energy bills, the need for immediate relief and long-term solutions has never been clearer. The current crisis serves as a reminder of the broader challenges facing the nation’s energy system and the importance of addressing both short-term needs and long-term sustainability. By investing in efficient technologies, supporting vulnerable populations, and developing resilient infrastructure, the U.S. can work towards a future where energy costs are manageable, and everyone has access to the resources they need to stay safe and comfortable.

Groups clash over NH hydropower project

Northern Pass Hydropower Project Rehearing faces review by New Hampshire's Site Evaluation Committee as Eversource seeks approval for a 192-mile transmission line, citing energy cost relief, while Massachusetts eyes Central Maine Power as an alternative.

 

Key Points

A review of Eversource's halted NH transmission plan, weighing impacts, costs, and alternatives.

✅ SEC denied project, Eversource seeks rehearing

✅ 192-mile line to bring Canadian hydropower to NE

✅ Alternative bids include Central Maine Power corridor

 

Groups supporting and opposing the Northern Pass hydropower project in New Hampshire filed statements Friday in advance of a state committee’s meeting next week on whether it should rehear the project.

The Site Evaluation Committee rejected the transmission proposal last month over concerns about potential negative impacts. It is scheduled to deliberate Monday on Eversource’s request for a rehearing.

The $1.6 billion project would deliver hydropower from Canada, including Hydro-Quebec exports, to customers in southern New England through a 192-mile transmission line in New Hampshire.

If the Northern Pass project fails to ultimately win New Hampshire approval, the Massachusetts Department of Energy Resources has announced it will begin negotiating with a team led by Central Maine Power Co. for a $950 million project through a 145-mile Maine transmission line as an alternative.

Separately, construction later began on the disputed $1 billion electricity corridor despite ongoing legal and political challenges.

The Business and Industry Association voted last month to endorse the project after remaining neutral on it since it was first proposed in 2010. A letter sent to the committee Friday urges it to resume deliberations. The association said it is concerned about the severe impact the committee’s decision could have on New Hampshire’s economic future, even as Connecticut overhauls electricity market structure across New England.

“The BIA believes this decision was premature and puts New Hampshire’s economy at risk,” organization President Jim Roche wrote. “New Hampshire’s electrical energy prices are consistently 50-60 percent higher than the national average. This has forced employers to explore options outside New Hampshire and new England to obtain lower electricity prices. Businesses from outside New Hampshire and others now here are reversing plans to grow in New Hampshire due to the Site Evaluation Committee’s decision.”

The International Brotherhood of Electrical Workers and the Coos County Business and Employers Group also filed a statement in support of rehearing the project.

The Society to Protect New Hampshire Forests, which is opposed to the project, said Eversource’s request is premature because the committee hasn’t issued a final written decision yet. It also said Eversource hasn’t proven committee members “made an unlawful or unreasonable decision or mistakenly overlooked matters it should have considered.”

As part of its request for reconsideration, Eversource said it is offering up to $300 million in reductions to low-income and business customers in the state.

It also is offering to allocate $95 million from a previously announced $200 million community fund — $25 million to compensate for declining property values, $25 million for economic development and $25 million to promote tourism in affected areas. Another $20 million would fund energy efficiency programs.

U.S. Renewable and Clean Energy Industries Set Sights on Market Majority

U.S. Majority Renewables by 2030 targets over half of electricity from wind, solar, hydropower, and energy storage, enabling a resilient, efficient grid, deep carbon reductions, fair market rules, and job growth across regions.

 

Key Points

A joint industry pledge for over 50% U.S. power from wind, solar, hydropower, and storage by 2030.

✅ Joint pledge by AWEA, SEIA, NHA, and ESA for a cleaner grid

✅ Focus on resilience, efficiency, affordability, and fair competition

✅ Storage enables flexibility to integrate variable renewables

 

Within a decade, more than half of the electricity generated in the U.S. will come from clean, renewable resources, with analyses indicating that wind and solar could meet 80% of U.S. electricity demand, supported by energy storage, according to a joint commitment today from the American wind, solar, hydropower, and energy storage industries. The American Wind Energy Association (AWEA), Solar Energy Industries Association (SEIA), National Hydropower Association (NHA), and Energy Storage Association (ESA) have agreed to actively collaborate across their industry segments to achieve this target. 

The four industries have released a set of joint advocacy principles that will enable them to realize this bold vision of a majority renewables grid. Along with increased collaboration, these shared principles include building a more resilient, efficient, sustainable, and affordable grid; achieving carbon reductions; and advancing greater competition through electricity market reforms and fair market rules. Each of these areas is critical to attaining the shared vision for 2030.  

The leaders of the four industry associations gathered to announce the shared vision, aligned with a broader 100% renewables pathway pursued nationwide, during the first CLEANPOWER annual conference for businesses across the renewable and clean energy spectrum. 

American Wind Energy Association 

"This collaborative promise sets the stage to deliver on the American electric grid of the future powered by wind, solar, hydropower, and storage," said Tom Kiernan, CEO of the American Wind Energy Association. "Market opportunities for projects that include a mix of technologies have opened up that didn't exist even a few years ago. And demand is growing for integrated renewable energy options. Individually and cooperatively, these sectors will continue growing to meet that demand and create hundreds of thousands of new jobs to strengthen economies from coast to coast, building a better, cleaner tomorrow. In the face of significant challenges the country is currently facing across pandemic response, economic, climate and social injustice problems, we are prepared to help lead toward a healthier and more equitable future."

Solar Energy Industries Association

"These principles are just another step toward realizing our vision for a Solar+ Decade," said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association. "In the face of this dreadful pandemic, our nation must chart a path forward that puts a premium on innovation, jobs recovery and a smarter approach to energy generation, reflecting expected solar and storage growth across the market. The right policies will make a growing American economy fueled by clean energy a reality for all Americans."

National Hydropower Association 

"The path towards an affordable, reliable, carbon-free electricity grid, supported by an ongoing grid overhaul for renewables, starts by harnessing the immense potential of hydropower, wind, solar and storage to work together," said Malcolm Woolf, President and CEO of the National Hydropower Association. "Today, hydropower and pumped storage are force multipliers that provide the grid with the flexibility needed to integrate other renewables onto the grid. By adding new generation onto existing non-powered dams and developing 15 GW of new pumped storage hydropower capacity, we can help accelerate the development of a clean energy electricity grid."

Energy Storage Association 

"We are pleased to join forces with our clean energy friends to substantially reduce carbon emissions by 2030, guided by practical decarbonization strategies, building a more resilient, efficient, sustainable, and affordable grid for generations to come," said ESA CEO Kelly Speakes-Backman. "A majority of generation supplied by renewable energy represents a significant change in the way we operate the grid, and the storage industry is a fundamental asset to provide the flexibility that a more modern, decarbonized grid will require. We look forward to actively collaborating with our colleagues to make this vision a reality by 2030."

Nuclear plants produce over half of Illinois electricity, almost faced retirement

Illinois Zero Emission Credits support nuclear plants via tradable credits tied to wholesale electricity prices, carbon costs, created by the Future Energy Jobs Bill to avert Exelon closures and sustain low-carbon power.

 

Key Points

State credits that value nuclear power's zero-carbon output, priced by market and carbon metrics to keep plants running.

✅ Pegged to wholesale prices, carbon costs, and state averages.

✅ Created by Future Energy Jobs Bill to prevent plant retirements.

✅ Supports Exelon Quad Cities and Clinton nuclear facilities.

 

Nuclear plants have produced over half of Illinois electricity generation since 2010, but the states two largest plants would have been retired amid the debate over saving nuclear plants if the state had not created a zero emission credit (ZEC) mechanism to support the facilities.

The two plants, Quad Cities and Clinton, collectively delivered more than 12 percent of the states electricity generation over the past several years. In May 2016, however, Exelon, the owner of the plants, announced that they had together lost over $800 million dollars over the previous six years and revealed plans to retire them in 2017 and 2018, similar to the Three Mile Island closure later announced for 2019 by its owner.

In December 2016, Illinois passed the Future Energy Jobs Bill, which established a zero emission credit (ZEC) mechanism

to support the plants financially. Exelon then cancelled its plans to retire the two facilities.

The ZEC is a tradable credit that represents the environmental attributes of one megawatt-hour of energy produced from the states nuclear plants. Its price is based on a number of factors that include wholesale electricity market prices, nuclear generation costs, state average market prices, and estimated costs of the long-term effects of carbon dioxide emissions.

The bill is set to take effect in June, but faces multiple court challenges as some utilities have expressed concerns that the ZEC violates the commerce clause and affects federal authority to regulate wholesale energy prices, amid gas-fired competition in nearby markets that shapes the revenue outlook.

Illinois ranks first in the United States for both generating capacity and net electricity generation from nuclear power, a resource many see as essential for net-zero emissions goals, and accounts for approximately one-eighth of the nuclear power generation in the nation.
