EPA Wastewater Rule Rollback signals a move to rewrite 2015 Clean Water Act guidelines for coal-fired power plants, easing wastewater rules as heavy metals, mercury, lead, arsenic, and selenium threaten rivers, lakes, public health.

 

Key Points

A planned EPA rewrite of 2015 wastewater limits for coal plants, weakening protections against toxic heavy metals.

✅ Targets 2015 Clean Water Act wastewater guidelines

✅ Affects coal-fired steam electric power plants

✅ Raises risks from mercury, lead, arsenic, selenium

 

The Environmental Protection Agency says it plans to scrap an Obama-era measure limiting water pollution from coal-fired power plants, mirroring moves to replace the Clean Power Plan elsewhere in power-sector policy.

A letter from EPA Administrator Scott Pruitt released Monday as part of a legal appeal and amid a broader rewrite of NEPA rules said he will seek to revise the 2015 guidelines mandating increased treatment for wastewater from steam electric power-generating plants.

Acting at the behest of energy groups and electric utilities who opposed the stricter standards, Pruitt first moved in April to delay implementation of the new guidelines. The wastewater flushed from the coal-fired plants into rivers and lakes typically contains traces of such highly toxic heavy metals as lead, arsenic, mercury and selenium.

“After carefully considering your petitions, I have decided that it is appropriate and in the public interest to conduct a rulemaking to potentially revise (the regulations),” Pruitt wrote in the letter addressed to the pro-industry Utility Water Act Group and the U.S. Small Business Administration.

Pruitt’s letter, dated Friday, was filed Monday with the Fifth Circuit U. S. Court of Appeals in New Orleans, which is hearing legal challenges of the wastewater rule. With Pruitt now moving to rewrite the standards, EPA has asked to court to freeze the legal fight.

While that process moves ahead, EPA’s existing guidelines from 1982 remian in effect. Those standards were set when far less was known about the detrimental impacts of even tiny levels of heavy metals on human health and aquatic life.

“Power plants are by far the largest offenders when it comes to dumping deadly toxics into our lakes and rivers,” said Thomas Cmar, a lawyer for the legal advocacy group Earthjustice. “It’s hard to believe that our government officials right now are so beholden to big business that they are willing to let power plants continue to dump lead, mercury, chromium and other dangerous chemicals into our water supply.”

EPA estimates that the 2015 rule, if implemented, would reduce power plant pollution, consistent with new pollution limits proposed for coal and gas plants, by about 1.4 billion pounds a year. Only about 12 per cent of the nation’s steam electric power plants would have to make new investments to meet the higher standards, according to the agency.

Utilities would need to spend about $480 million on new wastewater treatment systems, resulting in about $500 million in estimated public benefits, such as fewer incidents of cancer and childhood developmental defects.

California regulators weigh whether the state needs more power plants

California Natural Gas Plant Rethink signals a shift toward clean energy, renewables, distributed solar, battery storage, and grid modernization as LADWP and regulators pause repowering plans amid an electricity oversupply and rising ratepayer costs.

 

Key Points

California pauses new gas plants to assess renewables, storage, and grid solutions for reliability.

✅ LADWP delays $2.2B gas repowers to study clean alternatives

✅ CEC weighs halting Oxnard plant amid grid oversupply

✅ Distributed solar, batteries, demand response boost reliability

 

California energy officials are, for the first time, rethinking plans to build expensive natural gas power plants in the face of an electricity glut and growing use of cleaner and cheaper energy alternatives.

The Los Angeles Department of Water and Power announced Tuesday that it has put a hold on a $2.2-billion plan to rebuild several old natural gas power plants while it studies clean energy alternatives to meet electricity demands. And the California Energy Commission may decide as early as Thursday to halt a natural gas project in Ventura County.

The scrutiny comes after an investigation found that the state is operating with an oversupply of electricity, driven largely by the construction of gas-fueled generating plants, leading to higher rates as regulators consider a rate overhaul to clean the grid. The state’s power plants are on track to be able to produce at least 21% more electricity than needed by 2020, according to the Times report.

Californians are footing a $40-billion annual bill while using less electricity, paying $6.8 billion more than they did in 2008 when power use in the state was at its all-time high. Electricity consumption has since fallen and remained largely flat.

Utilities in California have been on a years-long building binge, adding new natural gas plants even as the nation’s electricity system has undergone significant change, including consumer choice reforms that are reshaping the market.

Where utilities once delivered all electrical services from huge power plants along miles of transmission lines, the industry now must consider power delivered to the electric grid not only from its own sources, but also from solar systems and batteries at homes and businesses.

At the same time, utilities have been aggressively upgrading or rebuilding their aging natural gas plants — a move critics have said is unnecessary because consumers are using less power and clean energy technology is making those plants obsolete.

The DWP and energy commission moves involve as many as seven natural gas plant projects proposed for Southern California, despite warnings about a looming shortage if capacity is retired too fast, from Oxnard to Carlsbad, at a cost of more than $6 billion.

Reiko Kerr, the DWP’s senior assistant general manager of power systems, said given the changes in the energy world, the assessment is necessary to protect ratepayer dollars and the environment.

“The whole utility paradigm has shifted,” Kerr said in an interview. “We really are doing our ratepayers a disservice by not considering all viable options.

“We’re just looking at everything,” she said. “What can help us solve this reliability, renewable and greenhouse gas challenge that we all have?”

State and local governments have felt a heightened sense of urgency to deal with climate change after President Trump decided last week to withdraw the United States from the Paris climate accord.

California already has mandated that at least 50% of the state’s electricity come from clean energy sources by 2030. Senate leader Kevin de León (D-Los Angeles) wants to increase that to 100% by 2045.

Building or overhauling natural gas plants throughout Southern California, environmentalists argue, isn’t helping achieve those goals, even as some contend the state can't keep the lights on without gas during the transition.

The DWP’s move to delay plans for the fossil fuel plants, which seemed all but set to be built, came as a surprise to clean-energy advocates, who hailed the decision.

“This is a great first step toward smart energy investments that save customers money, ensure the lights stay on and protect our health and environment,” Graciela Geyer of the Sierra Club said.

The environmental group said that if the utility had moved ahead with the $2.2-billion investment in repowering natural gas plants, it “would have blown an irreparable hole in the city and the state’s hopes to achieve 100% generation” from clean energy sources.

Angela Johnson Meszaros, attorney at EarthJustice, said in a statement: "As our city struggles with the worst smog we’ve seen in years, we appreciate that LADWP is taking some much-needed time to reassess its plans to build fossil fuel power plants. We look forward to the day that LADWP announces that we are going to power our city with 100% clean energy.”

The gas-fired generating units slated for demolition and rebuilding are at the Scattergood, Haynes and Harbor electricity plants, which range from 34 to 67 years old.

As a group, the three plants have generated less than 20% of their combined capacity since 2001. The Harbor facility has operated on the low end at just 7%, while Haynes ran on the high end at 22%.

“The old model, the old legacy clunkers, won’t get us into the future we want,” DWP’s Kerr said.

DWP staff members told the utility’s’ commissioners Tuesday that their analysis of possible alternatives would be completed no later than early 2018.

Separately, the California Energy Commission this week is evaluating whether to halt a natural gas project in Ventura County after the state’s electric grid operator offered to conduct a study of clean energy alternatives to the roughly $250-million project on Mandalay Bay in Oxnard.

An energy commission committee has been deliberating since a hearing Monday during which Southern California Edison and the project’s developer, NRG Energy, argued that a study is simply a delay tactic that probably would kill a project needed to ensure reliable electric service and to avoid blackouts during peak demand.

The California Independent System Operator, which runs the state’s electric grid, told the energy commission that it would take three to four weeks to conduct its study on alternatives to the Oxnard natural gas project.

“Here we have an actual offer by the ISO to do such an analysis,” Ellison Folk, a lawyer representing the city of Oxnard, told the energy commission as she pushed for the study. “Its view that this is an analysis worth doing is something worth taking seriously.”

Energy commission members reviewing the study proposal are scheduled to meet again Thursday to consider the offer.

The board of governors for the California Independent System Operator made the unusual offer at its May 1 meeting to conduct a eleventh-hour study of clean-energy alternatives to building a new natural gas plant.

“If we’re going to be moving forward with a gas plant at this time, in this juncture, in the context of everything that’s going on, not evaluating other alternatives that are viable, noncombustion alternatives, is a missed opportunity,” Angelina Galetiva. a commission board member, said during the May 1 meeting.

UK must be ready for rise of electric vehicles, says ABB chief

UK EV Charging Infrastructure is accelerating as ABB and Formula E spotlight fast charging, smart grids, and public stations, preparing Britain for mass electric vehicle adoption with expanded capacity, reliable connectors, and nationwide coverage.

 

Key Points

The UK network of charge points, grid capacity, and services enabling secure, scalable electric vehicle adoption.

✅ ABB urges rapid rollout of fast chargers and smart grid upgrades

✅ National Grid forecasts up to 9m EVs by 2030 in the UK

✅ Government GBP 400m investment targets reliable nationwide coverage

 

The UK should speed up preparations for the rise of electric vehicles, according to the chief executive of ABB, the world’s largest supplier of fast-charging points.

Speaking as the Switzerland-based engineering firm became the first official sponsor of the electric street racing series Formula E, Ulrich Spiesshofer predicted a flood of consumer take-up of plug-in cars, noting how EV inquiries surged in the UK during a recent fuel supply crisis.

And he added his voice to warnings that Britain must move faster to make sure owners of electric vehicles are not stymied by a shortage of charging bays or cost concerns among consumers.

“E-mobility is unstoppable, it’s just a question of how fast and how deep it will be deployed,” he said. “The UK has a big population that really wants to contribute to a greener, more sustainable world. But there’s always a question of whether it’s quick enough. In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up.”

 

How green are electric cars?

He said this would include adding to the UK’s network of electric charging points, as well as ensuring enough energy capacity so that the grid can cope with rising demand.

There are 14,344 charging connectors in the UK, according to ZapMap, which charts the scale of the UK’s network.

Those charging points served around 132,000 plug-in vehicles at the end of 2017, but the National Grid has predicted that the number of electric cars could surge to 9m by 2030.

“In the next couple of years, it’s in the interest of everybody to make sure the infrastructure is coming up,” said Spiesshofer.

He welcomed the government’s budget pledge to spend £400m on improving the UK’s charging point network but warned that the power grid also needed to be ready to meet the increased demand, which many argue is manageable with proper management approaches.

Electric cars have been forecast to add about 18 gigawatts of power demand to the grid, the equivalent of six Hinkley Point C nuclear power stations.

Spiesshofer said he hoped ABB’s sponsorship of Formula E, which will last until 2025, would help spur interest in electric cars and lead to technological breakthroughs, even as the US EV boom tests charging capacity elsewhere.

Seasonal power rates could cause consumer backlash

NB Power seasonal electricity rates face backlash amid smart grid delays, meter reading limits, and billing dispute risks, as consultants recommend AMI smart meters for accurate winter-summer pricing, time-of-use alignment, and consumer protection.

 

Key Points

NB Power seasonal electricity rates raise winter prices and lower summer prices to match costs, using accurate AMI metering.

✅ Requires midnight meter reads without AMI, increasing billing disputes.

✅ Shifts costs to electric-heat homes during high winter demand.

✅ Recommended to wait for smart grid AMI for time-of-use accuracy.

 

A consultant hired by NB Power is warning of significant consumer "backlash" if the utility is made to establish seasonal rates for electricity, as seen in B.C. and Quebec smart meter disputes among customers.

The consultant's report even suggests customers might have to read their own power meters at midnight twice a year — on April Fool's and Halloween — to make the system work.

"Virtually all bills will have errors ... billing disputes can be expected to increase, as seen in a $666 smart meter bill in N.S. that raised concerns, possibly dramatically, and there will be no means of resolving disputes in a satisfactory way," reads a report by Elenchus Research Associates that was commissioned by NB Power and filed with the Energy and Utilities Board on Thursday.

NB Power is in the middle of a year-long "rate design" review ordered by the EUB that is focused in part on whether the utility should charge lower prices for electricity in the summer and higher prices in the winter to better reflect the actual cost of serving customers.

New network of meters needed

Elenchus was asked to study how that might work but the company is arguing against any switch until NB Power upgrades its entire network of power meters, given old meters in N.B. have raised concerns.

Elenchus said seasonal rates require an accurate reading of every customer's power meter at midnight on March 31 and again on Oct. 31, the dates when power rates would switch between winter and summer prices.

A consultant's report says NB Power doesn't have the manpower to properly read meters if it brings in seasonal rates. (CBC)

But NB Power does not have the sophisticated infrastructure in place to read meters remotely, or the manpower to visit every customer location on the same day, so Elenchus said the utility would have to guesstimate bills or rely on the technical savvy and honesty of customers themselves.

"Customers could be asked to read their own meters late in the day on March 31 (and October 31)," suggested the report. "Aside from the obvious inconvenience and impracticality of that approach, NB Power would have no means of verifying the customers' meter reads."

Residential customers would see hike

Another looming controversy with seasonal rates is that it would raise costs for residential customers, especially to those who heat with electricity, a pressure seen with a 14% rate increase in Nova Scotia recently.

Elenchus estimated seasonal rates would add nearly $6 million to the cost of residential bills overall, with the largest increases flowing to those with baseboard heat.

Electric heat customers consume the majority of their power during the five months that would have the highest prices and Elenchus said that is another reason to wait for better power meters before proceeding.

NB Power has an ambitious plan to upgrade meters and related infrastructure as part of its transformation to a "smart grid," but it is a multi-year plan.

Once in place the utility would be able to read meters remotely hour to hour, allowing power rates to be adjusted for times of the day and days of the week as well as seasonally.

Consumers will also have in-home pricing and consumption displays to help them manage their bills.

Elenchus said waiting for those meters will give electric heat customers a chance to avoid higher seasonal costs by letting them shift power consumption to lower-priced parts of the day.

"The introduction of seasonal rates would be more acceptable once AMI (advanced metering infrastructure) has been deployed," concludes the report.

A final hearing on NB Power's rate design, where seasonal rates and other changes will be considered, amid a power market overhaul debate in Alberta that industry is watching, is scheduled for next April.

More than a third of Irish electricity to be green within four years

Ireland Wind and Solar Share 2022 highlights IEA projections of over 33% electricity generation from renewables, with variable renewable energy growth, capacity targets, EU policy shifts, and investments accelerating wind and solar deployment.

 

Key Points

IEA forecasts wind and solar to exceed 33% of Ireland's electricity by 2022, second in variable renewables after Denmark.

✅ IEA expects Ireland to surpass 33% wind and solar by 2022

✅ Denmark leads at ~70%; Germany and UK exceed 25%

✅ Investments and capacity targets drive renewable growth

 

The share of wind and solar in total electricity generation in Ireland is expected to exceed 33pc by 2022, according to the 'Renewables 2017' report from the International Energy Agency (IEA).

Among the findings, the report says that Denmark is on course to be the world leader in the variable renewable energy sector, with 70pc of its electricity generation expected to come from wind and solar renewables by 2022.

The Nordic country will be followed by Ireland, Germany and the UK, all of which are expected see their share of wind and solar energy in total electricity generation exceed 25pc, according to the IEA report.

In a move to increase the level of wind generation in Ireland, the Government-controlled Ireland Strategic Investment Fund (Isif) teamed up with German solar and wind park operator Capital Stage in January to invest €140m in 20 solar parks in Ireland.

#google#

The parks are being developed by Dublin-based Power Capital, and it marks the first time that Isif has committed to financing solar park developments in this country.

Globally, renewables accounted for almost two-thirds of net new power capacity, with nearly 165 gigawatts (GW) coming online in 2016.

This was a record year that was largely driven by a booming solar market in China and around the world.

In 2016 solar capacity around the world grew by 50pc, reaching over 74 GW, with China's solar PV accounting for almost half of this expansion. In another first, solar energy additions rose faster than any other fuel, surpassing the net growth in coal, the IEA report found.

China alone is responsible for over two-fifths of global renewable capacity growth, which, according to the IEA, is largely driven by concerns about the country's air pollution and capacity targets.

The Asian giant is also the world market leader in hydropower, bioenergy for electricity and heat, and electric vehicles, the IEA report said. In 2016 the United States remained the second largest growth market for renewables.

However, with US President Donald Trump withdrawing the country from the Paris Agreement on climate change, the country's commitment to renewable energy faces policy uncertainty.

Meanwhile, India continues to grow its renewable electricity capacity, and by 2022, the country is expected to more than double its current renewable electricity capacity, according to the IEA. For the first time, this growth over the forecast period (2016-2022) is higher compared with the European Union, according to the report.

Meanwhile in the EU, renewable energy growth over the forecast period is 40pc lower compared with the previous five-year period.

The low forecast in respect of the EU is based on a number of factors, the IEA said, including weaker electricity demand, overcapacity, and limited visibility on forthcoming auction capacity volumes in some markets.

Overall, the Government has committed to generating 40pc of its electricity from renewable energy sources by 2020.

That target is set to be missed, which would see the Government eventually having to fork out hundreds of millions of euro for carbon credits.

Later this year, Ireland will host Europe's biggest summit on Climate Innovation, during which over 50 nationwide events and initiatives will be held.

Student group asking government for incentives on electric cars

PEI Electric Vehicle Incentives aim to boost EV adoption through subsidies and rebates, advocated by Renewable Transport PEI, with MLAs engagement, modeling Norway's approach, offsetting HST gaps, and making electric cars more competitive for Islanders.

 

Key Points

PEI Electric Vehicle Incentives are proposed subsidies and rebates to make EVs affordable and competitive for Islanders.

✅ Targets EV adoption with rebates up to 20 percent

✅ Modeled on Norway policies; offsets prior HST-era gaps

✅ Backed by Renewable Transport PEI engaging MLAs

 

Noah Ellis, assistant director of Renewable Transport P.E.I., is asking government to introduce incentives for Islanders to buy electric cars, as cost barriers remain a key hurdle for many.

RTPEI is a group composed of high school students at Colonel Gray going into their final year."We wanted to give back and contribute to our community and our country and we thought this would be a good way to do so," Ellis told Compass.

 

Meeting with government

"We want to see the government bring in incentives for electric vehicles, similar to New Brunswick's rebate program, because it would make them more competitive with their gasoline counterparts," Ellis said.

'We wanted to give back and contribute to our community … we thought this would be a good way to do so.'— Noah Ellis

Ellis said the group has spoken with opposition MLAs and is meeting with cabinet ministers soon to discuss subsidies for Islanders to buy electric cars, noting that Atlantic Canadians are less inclined to buy EVs compared to the rest of the country.

He referred to Norway as a prime example for the province to model potential incentives, even as Labrador's EV infrastructure gaps underscore regional challenges — a country that, as of last year, announced nearly 40 per cent of the nation's newly registered passenger vehicles as electric powered.

'Incentives that are fiscally responsible'

Ellis said they group isn't looking for anything less than a 20 per cent incentive on electric vehicles — 10 per cent higher than the provinces cancelled hybrid car tax rebate that existed prior to HST.

"Electric vehicle incentives do work we just have to work with economists and environmentalists, and address critics of EV subsidies, to find the right balance of incentives that are fiscally responsible for the province but will also be effective," Ellis said.

Mississippi power plant costs cross $7.5B

Kemper County power plant costs and delays highlight lignite coal gasification, syngas production, carbon capture targets, and looming rate plans as Mississippi Power navigates Public Service Commission oversight and shareholder-ratepayer risk.

 

Key Points

Costs exceed $7.5B with repeated delays; rate impacts loom as syngas, lignite, and carbon capture systems mature.

✅ Estimate tops $7.5B; customers could fund about $4.3B

✅ Carbon capture target: 65% CO2 via syngas from lignite

✅ Rate plans pending before the Public Service Commission

 

A Mississippi utility on Monday delayed making proposals for how its customers should pay for an ever-more-expensive power plant, even as the estimated cost of the facility crossed $7.5 billion.

The Kemper County power plant will be tasked with mining lignite coal a few hundred yards away from the plant. That coal is moved through a process that will convert it to syngas. The syngas is then used to drive the energy output of the plant, and the resulting electricity is then moved into the grid, where transmission projects influence regional reliability and capacity.

Thomas Fanning, CEO of parent Southern Co., told shareholders in May that Mississippi Power would file rate plans for its Kemper County power plant this month. But still unable to operate the plant steadily enough to declare it finished, Mississippi Power punted, instead asking to hold rates level for 11 months to pay off costs that have already been approved by regulators.

Mississippi Power says it now hopes to reach commercial operation in June. The plant is more than three years behind schedule, with 10 delays announced in the past 18 months. It was originally supposed to cost $2.9 billion.

The company also said monday that it will have to replace troublesome parts of the facility much sooner than expected, including units that cool the synthetic gas produced from soft lignite coal by two gasifier units, plus ash handling systems in the gasifiers.

Kemper is designed to take synthetic gas, pipe it through a chemical plant to remove carbon dioxide and other chemicals, and then burn the gas in turbines to generate electricity. It’s designed to capture 65 percent of carbon dioxide from the coal, releasing only as much of the climate-warming gas as a typical natural gas plant. It’s a key effort nationally to maintain coal as a viable fuel source, even as coal unit retirements proceed in other states.

Mississippi Power raised its estimate of Kemper’s cost by $209.4 million, with shareholders absorbing $185.9 million, while ratepayers could be asked to pay $23.5 million. Overall, customers could be asked to pay $4.3 billion. Southern shareholders have agreed to absorb $3.1 billion, which has risen by $500 million since November.

The elected three-member Public Service Commission in 2015 allowed the company to raise rates on its 188,000 customers by $126 million a year. That paid for $840 million in Kemper work, which began generating electricity in 2014 using piped-in natural gas. Some items covered by that 15 percent rate increase will be paid off in coming months, but Mississippi Power now proposes to repay costs from regulatory proceedings earlier than originally projected.

In testimony filed with the Public Service Commission, Mississippi Power Chief Financial Officer Moses Fagin said that keeping rates level would reduce whiplash to customers when rates rise later to pay for Kemper, would pay off accumulated costs more quickly and would help the company wean itself off financial support from Southern Co. while maintaining credit ratings and positioning for a possible bond rating upgrade over time.

“Cash flow is important to the company in maintaining its current ratings and beginning to rebuild its credit strength on a more independent basis apart from the extraordinary parental support that has been required in recent years to maintain financial integrity,” Fagin testified.

Spokesman Jeff Shepard said Mississippi Power is still drawing up two rate plans — one requiring a sharp, immediate rate increase, and a “rate mitigation plan” that might cushion increases amid declining returns in coal markets. He said the company isn’t sure when it will file them. Fagin suggested the Public Service Commission set a new deadline of March 2, 2018.
