The Tennessee Valley Authority (TVA) is planning improvements to its transmission system in the Golden Triangle area, and the utility is encouraging public input on the planned improvements, beginning with an open house April 24 in Starkville, Mississippi.

Planned improvements include construction of a new 161-kilovolt transmission line, which will be approximately 13 miles long. The line will extend from the Catalpa Creek Substation west to TVA's Starkville Switching Station. Several alternative routes for segments of the line are being considered.

Improvements also include a new switching station. TVA plans to construct the Clayton Village Switching Station adjacent to the existing Lakeside Substation, located along State Route 82 and the route of the new line.

TVA will present alternatives for the route of the line at an open house to be held from 3 p.m. until 7 p.m. at the TVA Customer Service Center Auditorium on Research Boulevard in Starkville. Detailed maps showing the network of alternative routes for the power line and possible switching station locations will be available, and TVA staff will be on hand to answer questions, discuss potential concerns and receive comments on the proposals.

Nine EU countries oppose electricity market reforms as fix for energy price spike

EU Electricity Market Reform Opposition highlights nine states resisting an overhaul of the wholesale power market amid gas price spikes, urging energy efficiency, interconnection targets, and EU caution rather than redesigns affecting renewables.

 

Key Points

Nine EU states reject overhauling wholesale power pricing, favoring efficiency and prudent policy over redesigns.

✅ Nine states oppose redesign of wholesale power market.

✅ Call for efficiency and 15% interconnection by 2030.

✅ Ministers to debate responses amid gas-driven price spikes.

 

Germany, Denmark, Ireland and six other European countries said on Monday they would not support a reform of the EU electricity market, ahead of an emergency meeting of energy ministers to discuss emergency measures and the recent price spike.

European gas and power prices soared to record high levels in autumn and have remained high, prompting countries including Spain and France to urge Brussels to redesign its electricity market rules.

Nine countries on Monday poured cold water on those proposals, in a joint statement that said they "cannot support any measure that conflicts with the internal gas and electricity market" such as an overhaul of the wholesale power market altogether.

"As the price spikes have global drivers, we should be very careful before interfering in the design of internal energy markets," the statement said.

"This will not be a remedy to mitigate the current rising energy prices linked to fossil fuels markets across Europe."

Austria, Germany, Denmark, Estonia, Finland, Ireland, Luxembourg, Latvia and the Netherlands signed the statement, which called instead for more measures to save energy and a target for a 15% interconnection of the EU electricity market by 2030.

European energy ministers meet tomorrow to discuss their response to the price spike, including gas price cap strategies under consideration. Most countries are using tax cuts, subsidies and other national measures to shield consumers against the impact higher gas prices are having on energy bills, but EU governments are struggling to agree on a longer term response.

Spain has led calls for a revamp of the wholesale power market in response to the price spike, amid tensions between France and Germany over reform, arguing that the system is not supporting the EU's green transition.

Under the current system, the wholesale electricity price is set by the last power plant needed to meet overall demand for power. Gas plants often set the price in this system, which Spain said was unfair as it results in cheap renewable energy being sold for the same price as costlier fossil fuel-based power.

The European Commission has said it will investigate whether the EU power market is functioning well, but that there is no evidence to suggest a different system would have better protected countries against the surge in energy costs, and that rolling back electricity prices is tougher than it appears during such spikes.

Costa Rica hits record electricity generation from 99% renewable sources

Costa Rica Renewable Energy Record highlights 99.99% clean power in May 2019, driven by hydropower, wind, solar, geothermal, and biomass, enabling ICE REM electricity exports and reduced rates from optimized generation totaling 984.19 GWh.

 

Key Points

May 2019 benchmark: Costa Rica generated 99.99% of 984.19 GWh from renewables, shifting from imports to regional exports.

✅ 99.99% renewable share across hydro, wind, solar, geothermal, biomass

✅ 984.19 GWh generated; ICE suspended imports and exported via REM

✅ Geothermal output increased to offset dry-season hydropower variability

 

During the whole month of May 2019, Costa Rica generated a total of 984.19 gigawatt hours of electricity, the highest in the country’s history. What makes this feat even more impressive is the fact that 99.99% of this energy came from a portfolio of renewable sources such as hydropower, wind, biomass, solar, and geothermal.

With such a high generation rate, the state power company Instituto Costariccense de Electricidad (ICE) were able to suspend energy imports from the first week of May and shifted to exports, while U.S. renewable electricity surpassed coal in 2022 domestically. To date, the power company continues to sell electricity to the Regional Electricity Market (REM) which generates revenues and is likely to reduce local electricity rates, a trend echoed in places like Idaho where a vast majority of electricity comes from renewables.

The record-breaking power generation was made possible by optimization of the country’s renewable sources, much as U.S. wind capacity surpassed hydro capacity at the end of 2016 to reshape portfolios. As the period coincided with the tail end of the dry season, the geothermal quota had to be increased.

Costa Rica remains a leader in renewable power generation, whereas U.S. wind generation has become the most-used renewable source in recent years. In 2015, more than 98% of the country’s electrical generation came from renewable sources, while U.S. renewables hit a record 28% in April in one recent benchmark. Through the years, this figure has remained fairly constant despite dry bouts caused by the El Niño phenomenon, and U.S. solar generation also continued to rise.

Calgary electricity retailer urges government to scrap overhaul of power market

Alberta Capacity Market Overhaul faces scrutiny over electricity costs, reliability targets, investor certainty, and AESO design, as UCP reviews NDP reforms, renewables integration, and deregulated energy-only alternatives impacting generators, ratepayers, and future power price volatility.

 

Key Points

A shift paying generators for capacity and energy to improve reliability; critics warn of higher electricity costs.

✅ UCP reviewing NDP plan and subsidies amid market uncertainty

✅ AESO cites reliability needs as coal retires, renewables grow

✅ Critics predict overprocurement and premature launch cost spikes

 

Jason Kenney's government is facing renewed pressure to cancel a massive overhaul of Alberta's power market that one player says will needlessly spike costs by hundreds of millions of dollars, amid an electricity sector in profound change today.

Nick Clark, who owns the Calgary-based electricity retailer Spot Power, has sent the Alberta government an open letter urging it to walk away from the electricity market changes proposed by the former NDP government.

"How can you encourage new industry to open up when one of their raw material costs will increase so dramatically?" Clark said. "The capacity market will add more costs to the consumer and it will be a spiral downwards."

But NDP Leader Rachel Notley, whose government ushered in the changes, said fears over dramatic cost increases are unfounded.

"There are some players within the current electricity regime who have a vested interest in maintaining the current situation," Notley said

Kenney's UCP vowed during the recent election to review the current and proposed electricity market options, as the electricity market heads for a reshuffle, with plans to report on its findings within 90 days.

The party also promised to scrap subsidies for renewable power, while ensuring "a market-based electricity system" that emphasizes competition in Alberta's electricity market for consumers.

The New Democrats had opted to scrap the current deregulated power market — in place since the Klein era — after phasing out coal-fired generation and ushering in new renewable power as part of changes in how Alberta produces and pays for electricity under their climate change strategy.

The Alberta Electric System Operator, which oversees the grid, says the province will need new sources of electricity to replace shuttered coal plants and backstop wind and solar generators, while meeting new consumer demand.

After consulting with power companies and investors, the AESO concluded in late 2016 the electricity market couldn't attract enough investment to build the needed power generation under the current model.

The AESO said at the time investors were concerned their revenues would be uncertain once new plants are running. It recommended what's known as a capacity market, which compensates power generators for having the ability to produce electricity, even when they're not producing it.

In other words, producers would collect revenue for selling electricity into the grid and, separately, for having the capacity to produce power as a backstop, ensuring the lights stay on. Power generators would use this second source of income to help cover plant construction costs.

Clark said the complex system introduces unnecessary costs, which he believes would hurt consumers in the end. He said what's preventing investment in the power market is uncertainty over how the market will be structured in the future.

"What investors need to see in this market is price certainty, regulatory ease, and where the money they're putting into the marketplace is not at risk," he said.

"They can risk their own money, but if in fact the government comes in and changes the policy as it was doing, then money stayed away from the province."

Notley said a capacity market would not increase power bills but would avoid big price swings, with protections like a consumer price cap on power bills also debated, while bringing greener sources of energy into Alberta's grid.

"Moving back to the [deregulated] energy-only market would make a lot of money for a few people, and put consumers, both industrial and residential, at great risk."

Clark disagrees, citing Enmax's recent submissions to the Alberta Utilities Commission, in which the utility argues the proposed design of the capacity market is flawed.

In its submissions to the commission, which is considering the future of Alberta's power market, Enmax says the proposed system would overestimate the amount of generation capacity the province will need in the future. It says the calculation could result in Alberta procuring too much capacity.

The City of Calgary-owned utility says this could drive up costs by anywhere from $147 million to $849 million a year. It says a more conservative calculation of future electricity demand could avoid the extra expense.

An analysis by a Calgary energy consulting firm suggests a different feature of the proposed power market overhaul could also lead to a massive spike in costs.

EDC Associates, hired by the Consumers' Coalition of Alberta, argues the proposal to launch the new system in November 2021 may be premature, because it could bring in additional supplies of electricity before they're needed.

The consultant's report, also filed with the Alberta Utilities Commission, estimates the early launch date could require customers to pay 40 per cent more for electricity amid rising electricity prices in the province — potentially an extra $1.4 billion — in 2021/22.

"The target implementation date is politically driven by the previous government," said Duane Reid-Carlson, president of EDC Associates.

Reid-Carlson recommends delaying the launch date by several years and making another tweak: reducing the proposed target for system reliability, which would scale back the amount of power generation needed to backstop renewable sources.

"You could get a result in the capacity market that would give a similar cost to consumers that the [deregulated] energy-only market design would have done otherwise," he said.

"You could have a better risk profile associated with the capacity market that would serve consumers better through lower cost, lower price volatility, and it would serve generators better by giving them better access to capital at lower costs."

The UCP government did not respond to a request for comment.

Mexican president's contentious electricity overhaul defeated in Congress

Mexico Energy Reform Defeat underscores opposition unity as CFE-first rules, state regulators, and lithium nationalization falter amid USMCA concerns, investment risks, and clean energy transition impacts in Congress over power generation policy.

 

Key Points

The failed push to expand CFE control, flagged for USMCA risks, higher costs, regulator shifts, and slower clean energy transition.

✅ Bill to mandate 54% CFE generation and priority dispatch failed.

✅ Opposition cited USMCA breaches, higher prices, slower clean energy.

✅ Lithium nationalization to return via separate legislation.

 

Mexican President Andres Manuel Lopez Obrador's plan to increase state control of power generation was defeated in parliament on Sunday, as opposition parties united in the face of a bill they said would hurt investment and breach international obligations, concerns mirrored by rulings such as the Florida court on electricity monopolies that scrutinize market concentration.

His National Regeneration Movement (MORENA) and its allies fell nearly 60 votes short of the two-thirds majority needed in the 500-seat lower house of Congress, mustering just 275 votes after a raucous session that lasted more than 12 hours.

Seeking to roll back previous constitutional reforms that liberalized the electricity market, Lopez Obrador's proposed changes would have done away with a requirement that state-owned Comision Federal de Electricidad (CFE) sell the cheapest electricity first, a move reminiscent of debates when energy groups warned on pricing changes under federal proposals, allowing it to sell its own electricity ahead of other power companies.

Under the bill, the CFE would also have been set to generate a minimum of 54% of the country's total electricity, and energy regulation would have been shifted from independent bodies to state regulators, paralleling concerns raised when a Calgary retailer opposed a market overhaul over regulatory impacts.

The contentious proposals faced much criticism from business groups and the United States, Mexico's top trade partner as well as other allies who argued it would violate the regional trade deal, the United States-Mexico-Canada Agreement (USMCA), even as the USA looks to Canada for green power to deepen cross-border energy ties.

Lopez Obrador had argued the bill would have protected consumers and made the country more energy independent, echoing how Texas weighs market reforms to avoid blackouts to bolster reliability, saying the legislation was vital to his plans to "transform" Mexico.

Although the odds were against his party, he came into the vote seeking to leverage his victory in last weekend's referendum on his leadership.

Speaking ahead of the vote, Jorge Alvarez Maynez, a lawmaker from the opposition Citizens' Movement party, said the proposals, if enacted, would damage Mexico, pointing to experiences like the Texas electricity market bailout after a severe winter storm as cautionary examples.

"There isn't a specialist, academic, environmentalist or activist with a smidgen of doubt - this bill would increase electricity prices, slow the transition to (clean) energy in our country and violate international agreements," he added.

Supporters of clean-energy goals noted that subnational shifts, such as the New Mexico 100% clean electricity bill can illustrate alternative pathways to reform.

The bill also contained a provision to nationalize lithium resources.

Lopez Obrador said this week that if the bill was defeated, he would send another bill to Congress on Monday aiming to have at least the lithium portion of the proposed legislation passed.

Rising Solar and Wind Curtailments in California

California Renewable Energy Curtailment highlights grid congestion, midday solar peaks, limited battery storage, and market constraints, with WEIM participation and demand response programs proposed to balance supply-demand and reduce wasted solar and wind generation.

 

Key Points

It is the deliberate reduction of solar and wind output when grid limits or low demand prevent full integration.

✅ Grid congestion restricts transmission capacity

✅ Midday solar peaks exceed demand, causing surplus

✅ Storage, WEIM, and demand response mitigate curtailment

 

California has long been a leader in renewable energy adoption, achieving a near-100% renewable milestone in recent years, particularly in solar and wind power. However, as the state continues to expand its renewable energy capacity, it faces a growing challenge: the curtailment of excess solar and wind energy. Curtailment refers to the deliberate reduction of power output from renewable sources when the supply exceeds demand or when the grid cannot accommodate the additional electricity.

Increasing Curtailment Trends

Recent data from the U.S. Energy Information Administration (EIA) highlights a concerning upward trend in curtailments in California. In 2024, the state curtailed a total of 3,102 gigawatt-hours (GWh) of electricity generated from solar and wind sources, surpassing the 2023 total of 2,660 GWh. This represents a 32.4% increase from the previous year. Specifically, 2,892 GWh were from solar, and 210 GWh were from wind, marking increases of 31.2% and 51.1%, respectively, compared to the first nine months of 2023.

Causes of Increased Curtailment

Several factors contribute to the rising levels of curtailment:

  1. Grid Congestion: California's transmission infrastructure has struggled to keep pace with the rapid growth of renewable energy sources. This congestion limits the ability to transport electricity from generation sites to demand centers, leading to curtailment.

  2. Midday Solar Peaks: Amid California's solar boom, solar energy production typically peaks during the midday when electricity demand is lower. This mismatch between supply and demand results in excess energy that cannot be utilized, necessitating curtailment.

  3. Limited Energy Storage: While battery storage technologies are advancing, California's current storage capacity is insufficient to absorb and store excess renewable energy for later use. This limitation exacerbates curtailment issues.

  4. Regulatory and Market Constraints: Existing market structures and regulatory frameworks may not fully accommodate the rapid influx of renewable energy, leading to inefficiencies and increased curtailment.

Economic and Environmental Implications

Curtailment has significant economic and environmental consequences. For renewable energy producers, curtailed energy represents lost revenue and undermines the economic viability of new projects. Environmentally, curtailment means that clean, renewable energy is wasted, and the grid may rely more heavily on fossil fuels to meet demand, counteracting the benefits of renewable energy adoption.

Mitigation Strategies

To address the rising curtailment levels, California is exploring several strategies aligned with broader decarbonization goals across the U.S.:

  • Grid Modernization: Investing in and upgrading transmission infrastructure to alleviate congestion and improve the integration of renewable energy sources.

  • Energy Storage Expansion: Increasing the deployment of battery storage systems to store excess energy during peak production times and release it during periods of high demand.

  • Market Reforms: Participating in the Western Energy Imbalance Market (WEIM), a real-time energy market that allows for the balancing of supply and demand across a broader region, helping to reduce curtailment.

  • Demand Response Programs: Implementing programs that encourage consumers to adjust their energy usage patterns, such as shifting electricity use to times when renewable energy is abundant.

Looking Ahead

As California continues to expand its renewable energy capacity, addressing curtailment will be crucial to ensuring the effectiveness and sustainability of its energy transition. By investing in grid infrastructure, energy storage, and market reforms, the state can reduce curtailment levels and make better use of its renewable energy resources, while managing challenges like wildfire smoke impacts on solar output. These efforts will not only enhance the economic viability of renewable energy projects but also contribute to California's 100% clean energy targets by maximizing the use of clean energy and reducing reliance on fossil fuels.

While California's renewable energy sector faces challenges related to curtailment, proactive measures and strategic investments can mitigate these issues, as scientists continue to improve solar and wind power through innovation, paving the way for a more sustainable and efficient energy future.

Manitoba Government Extends Pause on New Cryptocurrency Connections

Manitoba Crypto Mining Electricity Pause signals a moratorium to manage grid strain, Manitoba Hydro capacity, infrastructure costs, and electricity rates, while policymakers evaluate sustainable energy demand, and planning for data centers and blockchain operations.

 

Key Points

A temporary halt on mining power hookups in Manitoba to assess grid impacts, protect rates, and plan sustainable use.

✅ Applies only to new service requests; existing sites unaffected

✅ Addresses grid strain, infrastructure costs, electricity rates

✅ Enables review with Manitoba Hydro for sustainable policy

 

The Manitoba government has temporarily suspended approving new electricity service connections for cryptocurrency mining operations, a step similar to BC Hydro's suspension seen in a neighboring province.


The Original Pause

The pause was initially imposed in November 2022 due to concerns that the rapid influx of cryptocurrency mining operations could place significant strain on the province's electrical grid. Manitoba Hydro, the province's primary electric utility, which has also faced legal scrutiny in the Sycamore Energy lawsuit, warned that unregulated expansion of the industry could necessitate billions of dollars in infrastructure investments, potentially driving up electricity rates for Manitobans.


The Extended Pause Offers Time for Review

The extension of the pause is meant to provide the government and Manitoba Hydro with more time to assess the situation thoroughly and develop a long-term solution addressing the challenges and opportunities presented by cryptocurrency mining, including evaluating emerging options such as modular nuclear reactors that other jurisdictions are studying. The government has stated its commitment to ensuring that the long-term impacts of the industry are understood and don't unintentionally harm other electricity customers.


What Does the Pause Mean?

The pause does not affect existing cryptocurrency operations but prevents the establishment of new ones.  It applies specifically to requests for electricity service that haven't yet resulted in agreements to construct infrastructure or supply electricity, and it comes amid regional policy shifts like Alberta ending its renewable moratorium that also affect grid planning.


Concerns About Energy Demands

Cryptocurrency mining involves running high-powered computers around the clock to solve complex mathematical problems. This process is incredibly energy-intensive. Globally, the energy consumption of cryptocurrency networks has drawn scrutiny for its environmental impact, with examples such as Iceland's mining power use illustrating the scale. In Manitoba, concern focuses on potentially straining the electrical grid and making it difficult for Manitoba Hydro to plan for future growth.


Other Jurisdictions Taking Similar Steps

Manitoba is not alone in its cautionary approach to cryptocurrency mining. Several other regions and utilities have implemented restrictions or are exploring limitations on how cryptocurrency miners can access electricity, including moves by Russia to ban mining amid power deficits. This reflects a growing awareness among policymakers about the potentially destabilizing impact this industry could have on power grids and electricity markets.


Finding a Sustainable Path Forward

Manitoba Hydro has stated that it is open to working with cryptocurrency operations but emphasizes the need to do so in a way that protects existing ratepayers and ensures a stable and reliable electricity system for all Manitobans, while recognizing market uncertainties highlighted by Alberta wind project challenges in a neighboring province. The government's extension of the pause signifies its intention to find a responsible path forward, balancing the potential for economic development with the necessity of safeguarding the province's power supply.
