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.

Alberta Electricity Rate Cap shields RRO customers with a 6.8 cents/kWh price ceiling, stabilizing power bills amid capacity market transition, using carbon tax funding to offset spikes and enhance consumer protection from volatility.

Key Points

A four-year 6.8 cents/kWh ceiling on Alberta's RRO power price, backed by carbon tax to stabilize bills.

✅ Applies to RRO customers from Jun 2017 to May 2021

✅ Caps rates at 6.8 cents/kWh; lower RRO still applies

✅ Funded by carbon tax when market prices exceed cap

The Alberta government introduced a bill Tuesday, part of new electricity rules that will allow it to place a cap on regulated electricity rates for the next four years.

The move to cap consumer power rates at a maximum of 6.8 cents per kilowatt-hour for four years was announced in November 2016 by Premier Rachel Notley, although it was later scrapped by the UCP during a subsequent policy shift.

The cap is intended to protect consumers from price fluctuations from June 1, 2017, to May 31, 2021, as the province moves from a deregulated to a capacity power market amid a power market overhaul that is underway.

The price ceiling will apply to people with a regulated rate option. If the RRO is below 6.8 cents, they will still pay the lower rate.

The government isn't forecasting price fluctuations above 6.8 cents in this four-year period. If the price goes above that amount, funding would come from the carbon tax if required.

Funding may come from carbon tax

"We're taking a number of steps to keep prices low," said Energy Minister Marg McCuaig-Boyd. "But in the event that prices were to spike, the cap would automatically prevent the energy rate from going over 6.8 cents to give Albertans even more peace of mind." 

The government isn't forecasting price fluctuations above 6.8 cents in this four-year period. If the price goes above that amount, funding would come from the carbon tax.

McCuaig-Boyd said this would be an appropriate use for the carbon tax as the cap helps Albertans move to a greener energy system and change how the province produces and pays for electricity without relying as much on coal-fired electricity. 

The government estimates the program will cost $10 million a month for each cent the rate goes above 6.8 cents per kilowatt-hour. If rates remain below that amount, the program may not cost anything.

Wildrose electricity and renewables critic Don MacInytre said the move shows the government expects retail electricity rates will double over the next four years. 

MacIntyre argued a rate cap simply shifts increasing electricity costs away from consumers to the Alberta government. But ultimately everyone pays. 

"It's simply a shift of a burden from the ratepayer to the taxpayer, which is essentially the same person," he said. 

The City of Medicine Hat runs its own electrical system without a regulated rate option. The government will talk with the city to see if it is interested in taking part in the price cap protection.

About 60 per cent of eligible Albertans or one million households use the regulated rate option in their electricity contracts.

The current regulated rate option averages less than three cents per kilowatt-hour.

Site C Project Delay raises BC Hydro costs as Christy Clark warns $600 million impact; NDP and Greens seek BCUC review of the hydroelectric dam on the Peace River, challenging evictions and construction contracts.

Key Points

A potential slowdown of B.C.'s Site C dam, risking $600M overruns, evictions, and schedule delays pending a BCUC review.

✅ Clark warns $600M cost if river diversion slips a year

✅ NDP-Green seek BCUC review; request to pause contracts, evictions

✅ Peace River hydro dam; schedule critical to budget, ratepayers

Premier Christy Clark is warning the NDP and Greens that delaying work on the Site C project in northeast British Columbia could cost taxpayers $600 million.

NDP Leader John Horgan wrote to BC Hydro last week asking it to suspend the evictions of two homeowners and urging it not to sign any new contracts on the $8.6-billion hydroelectric dam until a new government has gained the confidence of the legislature.

But Clark says in letters sent to Horgan and Green Leader Andrew Weaver on Tuesday that the evictions are necessary as part of a road and bridge construction project that are needed to divert a river in September 2019.

Any delay could postpone the diversion by a year and cost taxpayers hundreds of millions of dollars, she says.

“With a project of this size and scale, keeping to a tight schedule is critical to delivering a completed project on time and on budget,” she says. “The requests contained in your letter are not without consequences to the construction schedule and ultimately have financial ramifications to ratepayers.”

The premier has asked Horgan and Weaver to reply by Saturday on whether they still want to put the evictions on hold.

She also asks whether they want the government to issue a “tools down” request to BC Hydro on other decisions that she says are essential to maintaining the budget and construction schedule.

An agreement between the NDP and Green party was signed last week that would allow the New Democrats to form a minority government, ousting Clark's Liberals.

The agreement includes a promise to refer the Site C project to the B.C. Utilities Commission to determine its economic viability.

Some analysts argue that better B.C.-Alberta power integration could improve climate outcomes and market flexibility.

But Clark says the project is likely to progress past the “point of no return” before a review can be completed.

Clark did not define what she meant by “point of no return,” nor did she explain how she reached the $600-million figure. Her press secretary Stephen Smart referred questions to BC Hydro, which did not immediately respond.

During prolonged drought conditions, BC Hydro has had to adapt power generation across the province, affecting planning assumptions.

In a written response to Clark, Weaver says before he can comment on her assertions he requires access to supporting evidence, including signed contracts, the project schedule and potential alternative project timelines.

“Please let me express my disappointment in how your government is choosing to proceed with this project,” he says.

“Your government is turning a significant capital project that potentially poses massive economic risks to British Columbians into a political debate rather than one informed by evidence and supported by independent analysis.”

The dam will be the third on the Peace River, flooding an 83-kilometre stretch of valley, and local First Nations, landowners and farmers have fiercely opposed the project.

Construction began two years ago.

A report written by University of British Columbia researchers in April argued it wasn't too late to press pause on the project and that the electricity produced by Site C won't be fully required for nearly a decade after it's complete.

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.

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.

Renewables Beat Brown Coal in Australia, as solar and wind surged to nearly 10,000 GWh, stabilizing the grid with battery storage during peak demand, after Hazelwood's closure, Green Energy Markets reported.

Key Points

It describes a 2017-18 summer when solar, wind, and storage generated more electricity than brown coal in Australia.

✅ Solar and wind hit nearly 10,000 GWh in summer 2017-18

✅ Brown coal fell to about 9,100 GWh after Hazelwood closure

✅ Batteries stabilized peak demand; Tesla responded in milliseconds

Renewable energy generated more electricity than brown coal during Australia’s summer for the first time in 2017-18, according to a new report by Green Energy Markets.

Continued growth in solar, as part of Australia's energy transition, pushed renewable generation in Australia to just under 10,000 gigawatt hours between December 2017 and February 2018. With the Hazelwood plant knocked out of the system last year, brown coal’s output in the same period was just over 9,100 GWh.

Renewables produced 40% more than gas over the period, and was exceeded only by black coal, reflecting trends seen in U.S. renewables surpassing coal in 2022.

#google#

The report, commissioned by GetUp, found renewables were generating particularly large amounts of electricity when it was most needed, producing 32% more than brown coal during summer between 11am and 7pm, when demand peaks.

Coal in decline: an energy industry on life support

Solar in particular was working to support the system, on average producing more than Hazelwood was capable of producing between 9am and 5pm.

A further 5,000 megawatts of large-scale renewables projects was under construction in February, supporting 17,445 jobs, while renewables became the second-most prevalent U.S. electricity source in 2020.

GetUp’s campaign director, Miriam Lyons, said the latest renewable energy index showed renewables were keeping the lights on while coal became increasingly unreliable, a trend echoed as renewables surpassed coal in the U.S. in recent years.

“Over summer renewables kept houses cool and lights on during peak demand times when people needed electricity most,” Lyons said. “Meanwhile dirty old coal plants are becoming increasingly unreliable in the heat.

“These ageing clunkers failed 36 times over summer.

“Clean energy rescued people from blackouts this summer. When the clapped-out Loy Yang coal plant tripped, South Australia’s giant Tesla battery reacted in milliseconds to keep the power on.

“It’s clear that a smart electricity grid based on a combination of renewable energy and storage is the best way to deliver clean, affordable energy for all Australians.”

Revolution Wind Massachusetts will assemble turbine foundations in New Bedford, Fall River, or Somerset, building a local offshore wind supply chain, creating regional jobs, and leveraging pumped storage and an offshore transmission backbone.

Key Points

An offshore wind project assembling MA foundations, building a local supply chain, jobs, and peak clean power.

✅ 400 MW offshore wind; local fabrication of 1,500-ton foundations

✅ 300+ direct jobs, 600 indirect; MA crew vessel builds and operations

✅ Expandable offshore transmission; pumped storage for peak power

Deepwater Wind will assemble the wind turbine foundations for its Revolution Wind in Massachusetts, and it has identified three South Coast cities – New Bedford, Fall River and Somerset – as possible locations for this major fabrication activity, the company is announcing today.

Deepwater Wind is committed to building a local workforce and supply chain for its 400-megawatt Revolution Wind project, now under review by state and utility officials as Massachusetts advances projects like Vineyard Wind statewide.

“No company is more committed to building a local offshore wind workforce than us,” said Deepwater Wind CEO Jeffrey Grybowski. “We launched America’s offshore wind industry right here in our backyard. We know how to build offshore wind in the U.S. in the right way, and our smart approach will be the most affordable solution for the Commonwealth. This is about building a real industry that lasts.”

#google#

The construction activity will involve welding, assembly, painting, commissioning and related work for the 1,500-ton steel foundations supporting the turbine towers. This foundation-related work will create more than 300 direct jobs for local construction workers during Revolution Wind’s construction period. An additional 600 indirect and induced jobs will support this effort.

In addition, Deepwater Wind is now actively seeking proposals from Massachusetts boat builders for the construction of purpose-built crew vessels for Revolution Wind. Several dozen workers are expected to build the first of these vessels at a local boat-building facility, and another dozen workers will operate this specialty vessel over the life of Revolution Wind. (Deepwater Wind commissioned America’s only offshore wind crew vessel – Atlantic Wind Transfer’s Atlantic Pioneer – to serve the Block Island Wind Farm.)

The company will issue a formal Request for Information to local suppliers in the coming weeks. Deepwater Wind’s additional wind farms serving Massachusetts will require the construction of additional vessels, as will growth along Long Island’s South Shore in the coming years.

These commitments are in addition to Deepwater Wind’s previously-announced plans to use the New Bedford Marine Commerce Terminal for significant construction and staging operations, and to pay $500,000 per year to the New Bedford Port Authority to use the facility. During construction, the turbine marshaling activity in New Bedford is expected to support approximately 700 direct regional construction jobs.

“Deepwater Wind is building a sustainable industry on the South Coast of Massachusetts,” said Matthew Morrissey, Deepwater Wind Vice President Massachusetts. “With Revolution Wind, we are demonstrating that we can build the industry in Massachusetts while enhancing competition and keeping costs low.”

The Revolution Wind project will be built in Deepwater Wind’s federal lease site, under the BOEM lease process, southwest of Martha’s Vineyard. If approved, local construction work on Revolution Wind would begin in 2020, with the project in operations in 2023. Survey work is already underway at Deepwater Wind’s offshore lease area.

Revolution Wind will deliver “baseload” power, allowing a utility-scale renewable energy project for the first time to replace the retiring fossil fuel-fired power plants closing across the region, a transition echoed by Vineyard Wind’s first power milestones elsewhere.

Revolution Wind will be capable of delivering clean energy to Massachusetts utilities when it’s needed most, during peak hours of demand on the regional electric grid. A partnership with FirstLight Power, using its Northfield Mountain hydroelectric pumped storage in Northfield, Massachusetts, makes this peak power offering possible. This is the largest pairing of hydroelectric pumped storage and offshore wind in the world.

The Revolution Wind offshore wind farm will also be paired with a first-of-its-kind offshore transmission backbone. Deepwater Wind is partnering with National Grid Ventures on an expandable offshore transmission network that supports not just Revolution Wind, but also future offshore wind farms, as New York’s biggest offshore wind farm moves forward across the region, even if they’re built by our competitors.

This cooperation is in the best interest of Massachusetts electric customers because it will reduce the amount of electrical infrastructure needed to support the state’s 1,600 MW offshore wind goal. Instead of each subsequent developer building its own standalone cable network, other offshore wind companies could use expandable infrastructure already installed for Revolution Wind, reducing project costs and saving ratepayers money.
