Committee hears from Montana electricity companies

Duke Energy Carolinas Solar RFP draws 3.9 GW of utility-scale bids, oversubscribed in DEP and DEC, below avoided cost rates, minimal battery storage, strict PPA terms, and interconnection challenges across North and South Carolina.

Key Points

Utility-scale solar procurement in DEC and DEP, evaluated against avoided cost, with few storage bids and PPA terms.

✅ 3.9 GW bids for 680 MW; DEP most oversubscribed

✅ Most projects 7-80 MWac; few include battery storage

✅ Bids must price below 20-year avoided cost estimate

Last week the independent administrator for Duke’s 680 MW solar solicitation revealed data about the projects which have bid in response to the offer, showing a massive amount of interest in the opportunity.

Overall, 18 individuals submitted bids for projects in Duke Energy Carolinas (DEC) territory and 10 in Duke Energy Progress (DEP), with a total of more than 3.9 GW of proposals – more nearly 6x the available volume. DEP was relatively more over-subscribed, with 1.2 GWac of projects vying for only 80 MW of available capacity.

This is despite a requirement that such projects come in below the estimate of Duke’s avoided cost for the next 20 years, and amid changes in solar compensation that could affect project economics. Individual projects varied in capacity from 7-80 MWac, with most coming within the upper portion of that range.

These bids will be evaluated in the spring of 2019, and as Duke Energy Renewables continues to expand its portfolio, Duke Energy Communications Manager Randy Wheeless says he expects the plants to come online in a year or two.

Lack of storage

Despite recent trends in affordable batteries, of the 78 bids that came in only four included integrated battery storage. Tyler Norris, Cypress Creek Renewables’ market lead for North Carolina, says that this reflects that the methodology used is not properly valuing storage.

“The lack of storage in these bids is a missed opportunity for the state, and it reflects a poorly designed avoided cost rate structure that improperly values storage resources, commercially unreasonable PPA provisions, and unfavorable interconnection treatment toward independent storage,” Norris told pv magazine.

“We’re hopeful that these issues will be addressed in the second RFP tranche and in the current regulatory proceedings on avoided cost and state interconnection standards and grid upgrades across the region.”

Limited volume for North Carolina?

Another curious feature of the bids is that nearly the same volume of solar has been proposed for South Carolina as North Carolina – despite this solicitation being in response to a North Carolina law and ongoing legal disputes such as a church solar case that challenged the state’s monopoly model.

Miami Valley Windstorm Power Outages disrupted thousands as 60 mph gusts toppled trees, downed power lines, and damaged buildings. Utility crews and emergency services managed debris, while NWS alerts warned of extended restoration.

Key Points

Region-wide power losses from severe winds in the Miami Valley, causing damage, debris, and restoration.

✅ 60 mph gusts downed trees, snapped lines, blocked roads

✅ Crews from DP&L worked extended shifts to restore service

✅ NWS issued wind advisories; schools, businesses closed

On a recent day, powerful winds tore through the Miami Valley, causing significant disruption across the region. The storm, which was accompanied by gusts reaching dangerous speeds, led to windstorm power outages affecting thousands of homes and businesses. As trees fell and power lines were snapped, many residents found themselves without electricity for hours, and in some cases, even days.

The high winds, which were part of a larger weather system moving through the area, left a trail of destruction in their wake. In addition to power outages, there were reports of storm damage to buildings, vehicles, and other structures. The force of the wind uprooted trees, some of which fell on homes and vehicles, causing significant property damage. While the storm did not result in any fatalities, the destruction was widespread, with many communities experiencing debris-filled streets and blocked roads.

Utility companies in the Miami Valley, including Dayton Power & Light, quickly mobilized crews, similar to FPL's storm response in major events, to begin restoring power to the affected areas. However, the high winds presented a challenge for repair crews, as downed power lines and damaged equipment made restoration efforts more difficult. Many customers were left waiting for hours or even days for their power to be restored, and some neighborhoods were still experiencing outages several days after the storm had passed.

In response to the severe weather, local authorities issued warnings to residents, urging them to stay indoors and avoid unnecessary travel. Wind gusts of up to 60 miles per hour were reported, making driving hazardous, particularly on bridges and overpasses, similar to Quebec windstorm outages elsewhere. The National Weather Service also warned of the potential for further storm activity, advising people to remain vigilant as the system moved eastward.

The impact of the storm was felt not only in terms of power outages but also in the strain it placed on emergency services. With trees blocking roads and debris scattered across the area, first responders were required to work quickly and efficiently to clear paths and assist those in need. Many residents were left without heat, refrigeration, and in some cases, access to medical equipment that relied on electricity.

Local schools and businesses were also affected by the storm. Many schools had to cancel classes, either due to power outages or because roads were impassable. Businesses, particularly those in the retail and service sectors, faced disruptions in their operations as they struggled to stay open without power amid extended outages that lingered, or to address damage caused by fallen trees and debris.

In the aftermath of the storm, Miami Valley residents are working to clean up and assess the damage. Many homeowners are left dealing with the aftermath of tree removal, property repairs, and other challenges. Meanwhile, local governments are focusing on restoring infrastructure, as seen after Toronto's spring storm outages in recent years, and ensuring that the power grid is secured to prevent further outages.

While the winds have died down and conditions have improved, the storm’s impact will be felt for weeks to come, reflecting Florida's weeks-long restorations after severe storms. The region will continue to recover from the damage, but the event serves as a reminder of the power of nature and the resilience of communities in the face of adversity. For residents affected by the power outages, recovery will require patience as utility crews and local authorities work tirelessly to restore normalcy.

Looking ahead, experts are urging residents to prepare for the next storm season by ensuring that they have emergency kits, backup generators, and contingency plans in place. As climate change contributes to more extreme weather events, it is likely that storms of this magnitude will become more frequent. By taking steps to prepare in advance, communities across the Miami Valley can better handle whatever challenges come next.

US Climate Alliance 100% Renewables 2035 accelerates clean energy, electrification, and decarbonization, replacing coal and gas with wind, solar, and storage to cut air pollution, lower energy bills, create jobs, and advance environmental justice.

Key Points

A state-level target for alliance members to meet all electricity demand with renewable energy by 2035.

✅ 100% RES can meet rising demand from electrification

✅ Major health gains from reduced SO2, NOx, and particulates

✅ Jobs grow, energy burdens fall, climate resilience improves

The Union of Concerned Scientists joined with COPAL (Minnesota), GreenRoots (Massachusetts), and the Michigan Environmental Justice Coalition, to better understand the feasibility and implications of leadership states meeting 100 percent of their electricity needs with renewable energy by 2035, a target reflected in federal clean electricity goals under discussion today.

We focused on 24 member states of the United States Climate Alliance, a bipartisan coalition of governors committed to the goals of the 2015 Paris Climate Agreement. We analyzed two main scenarios: business as usual versus 100 percent renewable electricity standards, in line with many state clean energy targets now in place.

Our analysis shows that:

Climate Alliance states can meet 100 percent of their electricity consumption with renewable energy by 2035, as independent assessments of zero-emissions feasibility suggest. This holds true even with strong increases in demand due to the electrification of transportation and heating.

A transition to renewables yields strong benefits in terms of health, climate, economies, and energy affordability.

To ensure an equitable transition, states should broaden access to clean energy technologies and decision making to include environmental justice and fossil fuel-dependent communitieswhile directly phasing out coal and gas plants.

Demands for climate action surround us. Every day brings news of devastating "this is not normal" extreme weather: record-breaking heat waves, precipitation, flooding, wildfires. To build resilience and mitigate the worst impacts of the climate crisis requires immediate action to reduce heat-trapping emissions and transition to renewable energy, including practical decarbonization strategies adopted by states.

On the Road to 100 Percent Renewables explores actions at one critical level: how leadership states can address climate change by reducing heat-trapping emissions in key sectors of the economy as well as by considering the impacts of our energy choices. A collaboration of the Union of Concerned Scientists and local environmental justice groups COPAL (Minnesota), GreenRoots (Massachusetts), and the Michigan Environmental Justice Coalition, with contributions from the national Initiative for Energy Justice, assessed the potential to accelerate the use of renewable energy dramatically through state-level renewable electricity standards (RESs), major drivers of clean energy in recent decades. In addition, the partners worked with Greenlink Analytics, an energy research organization, to assess how RESs most directly affect people's lives, such as changes in public health, jobs, and energy bills for households.

Focusing on 24 members of the United States Climate Alliance (USCA), the study assesses the implications of meeting 100 percent of electricity consumption in these states, including examples like Rhode Island's 100% by 2030 plan that inform policy design, with renewable energy in the near term. The alliance is a bipartisan coalition of governors committed to reducing heat-trapping emissions consistent with the goals of the 2015 Paris climate agreement.[1]

On the Road to 100 Percent Renewables looks at three types of results from a transition to 100 percent RES policies: improvements in public health from decreasing the use of coal and gas2 power plants; net job creation from switching to more labor-oriented clean energy; and reduced household energy bills from using cleaner sources of energy. The study assumes a strong push to electrify transportation and heating to address harmful emissions from the current use of fossil fuels in these sectors. Our core policy scenario does not focus on electricity generation itself, nor does it mandate retiring coal, gas, and nuclear power plants or assess new policies to drive renewable energy in non-USCA states.

Our analysis shows that:

USCA states can meet 100 percent of their electricity consumption with renewable energy by 2035 even with strong increases in demand due to electrifying transportation and heating.

A transition to renewables yields strong benefits in terms of health, climate, economies, and energy affordability.

Renewable electricity standards must be paired with policies that address not only electricity consumption but also electricity generation, including modern grid infrastructure upgrades that enable higher renewable shares, both to transition away from fossil fuels more quickly and to ensure an equitable transition in which all communities experience the benefits of a clean energy economy.

Currently, the states in this analysis meet their electricity needs with differing mixes of electricity sourcesfossil fuels, nuclear, and renewables. Yet across the states, the study shows significant declines in fossil fuel use from transitioning to clean electricity; the use of solar and wind powerthe dominant renewablesgrows substantially:

In the study's "No New Policy" scenario"business as usual"coal and gas generation stay largely at current levels over the next two decades. Electricity generation from wind and solar grows due to both current policies and lowest costs.

In a "100% RES" scenario, each USCA state puts in place a 100 percent renewable electricity standard. Gas generation falls, although some continues for export to non-USCA states. Coal generation essentially disappears by 2040. Wind and solar generation combined grow to seven times current levels, and three times as much as in the No New Policy scenario.

A focus on meeting in-state electricity consumption in the 100% RES scenario yields important outcomes. Reductions in electricity from coal and gas plants in the USCA states reduce power plant pollution, including emissions of sulfur dioxide and nitrogen oxides. By 2040, this leads to 6,000 to 13,000 fewer premature deaths than in the No New Policy scenario, as well as 140,000 fewer cases of asthma exacerbation and 700,000 fewer lost workdays. The value of the additional public health benefits in the USCA states totals almost $280 billion over the two decades. In a more detailed analysis of three USCA statesMassachusetts, Michigan, and Minnesotathe 100% RES scenario leads to almost 200,000 more added jobs in building and installing new electric generation capacity than the No New Policy scenario.

The 100% RES scenario also reduces average energy burdens, the portion of household income spent on energy. Even considering household costs solely for electricity and gas, energy burdens in the 100% RES scenario are at or below those in the No New Policy scenario in each USCA state in most or all years. The average energy burden across those states declines from 3.7 percent of income in 2020 to 3.0 percent in 2040 in the 100% RES scenario, compared with 3.3 percent in 2040 in the No New Policy scenario.

Decreasing the use of fossil fuels through increasing the use of renewables and accelerating electrification reduces emissions of carbon dioxide (CO2), with implications for climate, public health, and economies. Annual CO2 emissions from power plants in USCA states decrease 58 percent from 2020 to 2040 in the 100% RES scenario compared with 12 percent in the No New Policy scenario.

The study also reveals gaps to be filled beyond eliminating fossil fuel pollution from communities, such as the persistence of gas generation to sell power to neighboring states, reflecting barriers to a fully renewable grid that policy must address. Further, it stresses the importance of policies targeting just and equitable outcomes in the move to renewable energy.

Moving away from fossil fuels in communities most affected by harmful air pollution should be a top priority in comprehensive energy policies. Many communities continue to bear far too large a share of the negative impacts from decades of siting the infrastructure for the nation's fossil fuel power sector in or near marginalized neighborhoods. This pattern will likely persist if the issue is not acknowledged and addressed. State policies should mandate a priority on reducing emissions in communities overburdened by pollution and avoiding investments inconsistent with the need to remove heat-trapping emissions and air pollution at an accelerated rate. And communities must be centrally involved in decisionmaking around any policies and rules that affect them directly, including proposals to change electricity generation, both to retire fossil fuel plants and to build the renewable energy infrastructure.

Key recommendations in On the Road to 100 Percent Renewables address moving away from fossil fuels, increasing investment in renewable energy, and reducing CO2 emissions. They aim to ensure that communities most affected by a history of environmental racism and pollution share in the benefits of the transition: cleaner air, equitable access to good-paying jobs and entrepreneurship alternatives, affordable energy, and the resilience that renewable energy, electrification, energy efficiency, and energy storage can provide. While many communities can benefit from the transition, strong justice and equity policies will avoid perpetuating inequities in the electricity system. State support to historically underserved communities for investing in solar, energy efficiency, energy storage, and electrification will encourage local investment, community wealth-building, and the resilience benefits the transition to renewable energy can provide.

A national clean electricity standard and strong pollution standards should complement state action to drive swift decarbonization and pollution reduction across the United States. Even so, states are well positioned to simultaneously address climate change and decades of inequities in the power system. While it does not substitute for much-needed national and international leadership, strong state action is crucial to achieving an equitable clean energy future.

US Electricity Demand 2018-2050 projects slower growth as energy consumption, power generation, air conditioning, and electric heating shift with efficiency standards, commercial floor space, industrial load, and household growth across the forecast horizon.

Key Points

A forecast of US power use across homes, commercial space, industrial load, and efficiency trends from 2018 to 2050.

✅ 2018 generation hit record; residential sales up 6%.

✅ Efficiency curbs demand; growth lags population and floor space.

✅ Commercial sales up 2%; industrial demand fell 3% in 2018.

Last year's Houston cold winter and hot summer drove power use to record levels, especially among households that rely on electricity for air conditioning during extreme weather conditions.

Electricity generation increased 4 per cent nationwide in 2018 and produced 4,178 million megawatt hours, driven in part by record natural gas generation across the U.S., surpassing the previous peak of 4,157 megawatt hours set in 2007, the Energy Department reported.

U.S. households bought 6 percent more electricity in 2018 than they did the previous year, despite longer-term declines in national consumption, reflecting the fact 87 percent of households cool their homes with air conditioning and 35 percent use electricity for heating.

Electricity sales to the commercial sector increased 2 percent in 2018 compared to the previous year while the industrial sector bought 3 percent less last year.

Going forward, the Energy Department forecasts that electricity consumption will grow at a slower pace than in recent decades, aligning with falling sales projections as technology improves and energy efficiency standards moderate consumption.

The economy and population growth are primary drivers of demand and the government predicts the number of households will grow at 0.7 percent per year from now until 2050 but electricity demand will grow only by 0.4 percent annually.

Likewise, commercial floor space is expected to increase 1 percent per year from now until 2050 but electricity sales will increase only by half that amount.

Globally, surging electricity demand is putting power systems under strain, providing context for these domestic trends.

Iran-Iraq Electricity Cooperation advances with power grid synchronization, cross-border energy trade, 400-kV transmission lines, and education partnerships, boosting grid reliability, infrastructure investment, and electricity exports between Tehran and Baghdad for improved supply and stability.

Key Points

A bilateral initiative to synchronize grids, expand networks, and sustain electricity exports, improving reliability.

✅ 400-kV Amarah-Karkheh line enables synchronized operations.

✅ Extends electricity export contracts to meet Iraq demand.

✅ Enhances grid reliability, training, and infrastructure investment.

Aradakanian has focused his one-day visit to Iraq on discussions pertaining to promoting bilateral collaboration between the two neighboring nations in the field of electricity, grid development deals and synchronizing power grid between Tehran and Baghdad, cooperating in education, and expansion of power networks.

He is also scheduled to meet with Iraqi top officials in a bid to boost cooperation in the relevant fields.

Back in December 2019, Ardakanian announced that Iran will continue exports of electricity to Iraq by renewing earlier contract as it is supplying about 40% of Iraq's power today.

"Iran has signed a 3-year-long cooperation agreement with Iraq to help the country's power industry in different aspects. The documents states at its end that we will export electricity to Iraq as far as they need," Ardakanian told FNA on December 9, 2019.

The contract to "export Iran's electricity" to Iraq will be extended, he added.

Ardakanian also said that Iran and Iraq's power grids have become synchronized in a move that supports Iran's regional power hub plans since a month ago.

In 2004 Iran started selling electricity to Iraq. Iran electricity exports to the western neighbor are at its highest level of 1,361 megawatts per day now, as the country weighs summer power sufficiency ahead of peak demand.

The new Amarah-Karkheh 400-KV transmission line stretching over 73 kilometers, is now synchronized to provide electricity to both countries, reflecting regional power export trends as well. It also paves the way for increasing export to power-hungry Iraq in the near future.

With synchronization of the two grids, the quality of electricity in Iraq will improve as the country explores nuclear power options to tackle shortages.

According to official data, 82% of Iraq's electricity is generated by thermal power plants that use gas as feedstock, while Iran is converting thermal plants to combined cycle to save energy. This is expected to reach 84% by 2027.

South Carolina Energy Freedom Act lifts net metering caps, reforms PURPA, and overhauls utility planning to boost solar competition, grid resiliency, and consumer choice across the Southeast amid Santee Cooper debt and utility monopoly pressure.

Key Points

A bipartisan reform lifting net metering caps, modernizing PURPA, and updating utility planning to expand solar.

✅ Lifts net metering cap to accelerate rooftop and community solar.

✅ Reforms PURPA contracts to enable fair pricing and transparent procurement.

✅ Modernizes utility IRP and opens markets to competition and customer choice.

The South Carolina House has approved the latest version of the Energy Freedom Act, a bill that overhauls the state’s electricity policies, including lifting the net metering caps and reforming PURPA implementation and utility planning processes in a way that advocates say levels the playing field for solar at all scales.

With Governor Henry McMaster (R) expected to sign the bill shortly, this is a major coup not just for solar in the state, but the region. This is particularly notable given the struggle that solar has had just to gain footing in many parts of the South, which is dominated by powerful utility monopolies and conservative politicians.

Two days ago when the bill passed the Senate we covered the details of the policy, but today we’re going to take a look at the politics of getting the Energy Freedom Act passed, and what this means for other Southern states and “red” states.

Opportunity amid crisis

The first thing to note about this bill is that it comes within a crisis in South Carolina’s electricity sector. This was the first legislative session following state-run utility Santee Cooper’s formal abandonment of a project to build two new reactors at the Virgil C. Sumner nuclear power plant, on which work stopped nearly two years ago.

Santee Cooper still holds $4 billion in construction debt related to the nuclear projects. According to an article in The State, this is costing its customers $5 per month toward the current debt, and this will rise to $13 per month for the next 40 years.

Such costs are particularly unwelcome in South Carolina, which has the highest annual electricity bills in the nation due to a combination of very high electricity usage driven by widespread air conditioning during the hot summers and higher prices per unit of power than other Southern states.

Following this fiasco, Santee Cooper’s CEO has stepped down, and the state government is currently considering selling the utility to a private entity. According to Maggie Clark, southeast state affairs senior manager for Solar Energy Industries Association, all of this set the stage for the bill that passed today.

“South Carolina is in a really ripe state for transformational energy policy in the wake of the VC Sumner nuclear plant cancellation,” Clark told pv magazine. “They were looking for a way forward, and I think this bill really provided them something to champion.”

Renewable energy policy for red states

This major win for solar policy comes in a state where the Republican Party holds majorities in both houses of the state’s legislature and sends bills to a Republican governor.

Broadly speaking, Republican politicians seldom show the level of interest in supporting renewable energy that Democrats do either at the state or national level, and show even less inclination to act to address greenhouse gas emissions. In fact, the 100% clean energy mandates that are being implemented in four states and Washington D.C. have only passed with Democratic trifectas, in other words with Republicans controlling neither house of the state legislature nor the governor’s office. (Note: This does not apply to Puerto Rico, which has a different party structure to the rest of the United States)

However, South Carolina shows there are Republican politicians who will support pro-renewable energy policies, and circumstances under which Republican majorities will vote for legislation that aids the adoption of solar. And these specific circumstances speak to both different priorities and ideological differences between the two parties.

SEIA’s Maggie Clark emphasizes that the Energy Freedom Act was about reforming market rules. “This was a way to provide a program that did not provide subsidies or incentives in any way, but to really open the market to competition,” explains Clark. “I think that appealing to conservatives in the South about energy independence and resiliency and ultimately cost savings is the winning message on this issue.”

Such messaging in South Carolina is not an accident. Not only has such messaging been successful in the past, but coalition partner Vote Solar paid for polling to find what messages resounded with the state’s voters, and found that choice and competition were likely to resound.

And all of this happened in the context of what Clark describes as an “extremely well-resourced effort”, with SEIA in particular dedicating national attention and resources to the state – as part of an effort by President and CEO Abigail Hopper to shift attention more towards state-level policy. Maggie Clark is one of two new regional staff who Hopper has hired, and SEIA’s first staff member focused on Southern states.

“Absolutely the South is a prioritized region,” Hopper told pv magazine, noting that three Southern states – the Carolinas and Florida – are among the 12 states that the organization has identified to work on this year. “It became clear that as a region it needed more attention.”

SEIA is not expecting fly-by-night victories, and Hopper attributes the success in South Carolina not only to a broad coalition, but to years of work on the ground in the state.

Nor is SEIA the only organization to grow its presence in the region. Vote Solar now has two full time staff located in the South, whereas two years ago its sole staff member dedicated to the region was located in Washington D.C.

Ideology versus reality in the South

The Energy Freedom Act aligns with conservative ideas about small government and competition, but the American right is not monolithic, nor do political ideas and actions always line up neatly, as other successful policies in other states in the region show

By far the largest deployment of renewable energy in the nation has been in Texas, aside from in California which leads overall. Here a system of renewable energy zones in the sparsely populated but windy and sunny west, north and center of the state feed cities to the east with power from wind and more recently solar.

This was enabled by transmission lines whose cost was socialized among the state’s ratepayers – a tremendous irony given that the state’s politicians would be some of the last in the nation to want to be identified with socializing anything.

Another example is Louisiana, which saw a healthy residential solar market over the last decade due to a 50% state rebate. The policy has expired, but when operating it was exactly the sort of outright subsidy that right-wing media and politicians rail against.

Of course there is also North Carolina, which built the 2nd-largest solar market in the nation on the back of successful state-level implementation of PURPA, a federal law. Finally there is Virginia, where large-scale projects are booming following a 2018 law that found that 5 GW of solar is in the public interest.

Furthermore, while conservatives continually expound the virtues of the free market, the reality of the electricity sector in the “deep red” South is anything but that. The region missed out on the wave of deregulation in the 1990s, and remains dominated by monopoly utilities regulated by the state: a union of big business and big government where competition is non-existent.

This has also meant that the solar which has been deployed in the South is mostly not the kind of rooftop solar that many think of as embodying energy independence, but rather large-scale solar built in farms, fields and forests.

Where to from here?

With such contradictions between stated ideology and practice, it is less clear what makes for successful renewable energy policy in the South. However, opening up markets appears to be working not only in South Carolina, but also in Florida, where third-party solar companies are making inroads after the state’s voters rejected a well-funded and duplicitous utilities’ campaign to kill distributed solar.

SEIA’s Hopper says that she is “aggressively optimistic” about solar in Florida. As utilities have dominated large-solar deployment in the state, even as the state declined federal solar incentives earlier this year, she says that she sees opening up the state’s booming utility-scale solar market to competition as a priority.

Some parts of the region may be harder than others, and it is notable that SEIA has not had as much to say about Alabama, Mississippi or Louisiana, which are largely controlled by utility giants Southern Company and Entergy, or the area under the thumb of the Tennessee Valley Authority, one of the most anti-solar entities in the power sector.

Abby Hopper says ultimately, demand from customers – both individuals and corporations – is the key to transforming policy. “You replicate these victories by customer demand,” Hopper told pv magazine. “That combination of voices from the customer are what’s going to drive change.”
