When TVA buys electricity from producers of renewable energy, there's more to the transaction than exchanging dollars.

Attached to each megawatt hour is a renewable energy certificate, which has a value determined at state and international auctions, in large part, because it allows buyers to offset their carbon emissions and sellers to reap additional revenues in addition to the power they produce.

RECs aren't new, but they haven't made much local relevance until recently.

Tennessee doesn't have a renewable portfolio standard, which requires utilities to utilize a certain percentage of green power, or much renewable electricity production. And the lack of movement on federal cap-and-trade legislation has kept the instruments out of the limelight.

But TVA's recent decision to buy more renewable power, coupled with investors seeking ways to profit from green energy production, has pushed RECs into the local conversation — and in the case of at least one area solar developer, they've become part of its business plan.

TVA says its still determining what to do with the growing number of certificates it will acquire in the coming months.

TVA currently owns about 200,000 certificates, but will acquire several million between now and 2013, with the bulk coming in 2012 when the wind power it's contracted for comes online, says Steve Lomax, TVA senior manager for clean and renewable energy.

"We were preparing for what we anticipated to be a federal policy mandate that has not yet materialized," Lomax says. Now the agency must decide, "What do we do with the renewable credits that we have?"

TVA's current certificates were generated by its wind turbines, perched atop Buffalo Mountain near Oak Ridge, as well as its Generation Partners program, which pays customers a premium for the renewable power they generate. Per contract, TVA will also own the RECs associated with its new Standard Offer program, created for larger green power installations.

TVA has used the certificates as part of its Green Power Switch program, in which customers pay a premium for green energy, Lomax says, and to fulfill a federal order, which requires 5 percent of the electricity used by federal agencies to be generated by renewable sources.

TVA this fall announced deals to buy more than 1,600 megawatts of wind power and the associated RECs from a variety of providers, primarily in the Midwest, Lomax says.

The markets for RECs are created by renewable portfolio standards — now adopted in 30 states and the District of Columbia — that require power companies to provide a certain percentage of power from renewable sources. Voluntary markets, such as Tennessee, are those in which customers purchase green power simply because they want to.

Local solar developers have expressed frustration at TVA's stance, particularly in the recent launch of a new program set up for larger renewable generation systems that don't qualify for Generation Partners. The program's pricing structure is inadequate for solar investors, and they argue TVA should have taken the value of solar RECs — which trade at a higher price because several states have solar-power requirements for producers' portfolio — into account when the agency buys solar power.

But Lomax says the market for RECs is too uncertain right now to factor into power purchases.

"Theoretically it could be of consideration for the pricing if they were of value and if the market needed them," he says. "It really comes down to... are you choosing preferential renewable energy resources. Are you treating them all fairly?"

One local company has developed a financing program for solar systems built around the value of RECs versus the value of TVA's incentive programs.

TerraShares, a Morristown environmental services company, has been working to help organizations offset the initial capital costs by using third-party investors to finance and operate solar installations.

The company first explored the potential of RECs when TVA temporarily suspended its Generation Partners program earlier this year, says TerrShares founder John Atkins.

"Everyone was running around, understandably, like Chicken Little wondering what they were going to do," he says. "What we found is there are places we can sell those RECs. In fact, the revenue from those sources is better than Generation Partners."

TerraShares' customers would not feed TVA's electric grid, but would use the electricity to power their own operations.

"The history is that prices have been very stable in these auctions," Atkins says.

LOC Renewables Delivers First MWS Services To China's Offshore Wind Market

Pinghai Bay Offshore Wind Farm MWS advances marine warranty survey best practices, risk management, and international standards in Fujian, with Haixia Goldenbridge Insurance and reinsurer-aligned audits supporting safer offshore wind construction and logistics.

 

Key Points

An MWS program ensuring Pinghai Bay Phase 2 meets standards via audits, risk controls, and vetted procedures.

✅ First MWS delivered in China's offshore wind market

✅ Audits, risk consultancy, and reinsurer-aligned standards

✅ Supports 250MW Phase 2 at Pinghai Bay, Fujian

 

LOC Renewables has announced it is to carry out marine warranty survey (MWS) services for the second phase of the Pinghai Bay Offshore Wind Farm near Putian, Fujian province, China, on behalf of Haixia Goldenbridge Insurance Co., Ltd. The agreement represents the first time MWS services have been delivered to the Chinese offshore wind market.

China’s installed offshore capacity jumped more than 60% in 2017, and its growing offshore market is aiming for a total grid-connected capacity of 5GW by 2020, as the sector globally advances toward a $1 trillion industry over the coming decades. Much of this future offshore development is slated to take place in Jiangsu, Zhejiang, Guangdong and Fujian provinces. As developers becoming increasingly aware of the need for stringent risk management and value that internationally accepted standards can bring to projects, Pinghai Bay will be the first Chinese offshore wind farm to employ MWS to ensure it meets the highest technical standards and minimise project risk. The agreement will see LOC Renewables carry out audit and risk consultancy services for the project from March until the end of 2018.

In recent years, as Chinese offshore wind projects have grown in scale and complexity the need for international expertise in the market has increased, with World Bank support for emerging markets underscoring global momentum. In response, domestic insurers are partnering with international reinsurers to manage and mitigate the associated larger risks. Applying the higher standards required by international reinsurers, LOC Renewables will draw on its extensive experience in European, US and Asian offshore wind markets to provide MWS services on the Pinghai project from its Tianjin office.

“As offshore wind technology continues to proliferate across Asia, driven by declining global costs, successful knowledge transfer based on best practices and lessons learned in the established offshore wind markets becomes ever more important,” said Ke Wan, Managing Director, LOC China.

“With a wealth of experience in Europe and the US, where UK offshore wind growth has accelerated, we’re increasingly working on projects across Asia, and are delighted to now be providing the first MWS services to China’s offshore wind market – services that bring real value in lower risk and will enable the project to achieve its full potential.”

“At 250MW, phase two of the Pinghai Bay Wind Farm represents a significant expansion on phase one, and we wanted to ensure that it met the highest technical and risk mitigation standards, informed by regional learnings such as Korean installation vessels analyses,” said Fan Ming, Business Director at Haixia Goldenbridge Insurance.

“In addition to their global experience, LOC Renewables’ familiarity with and presence in the local market was very important to us, and we’re looking forward to working closely with them to help bring this project to fruition and make a significant contribution to China’s expanding offshore wind market.”

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

Ontario Energy minister downplays dispute between auditor, electricity regulator

Ontario IESO Accounting Dispute highlights tensions over public sector accounting standards, auditor general oversight, electricity market transparency, KPMG advice, rate-regulated accounting, and an alleged $1.3B deficit understatement affecting Hydro bills and provincial finances.

 

Key Points

A PSAS clash between Ontario's auditor general and the IESO, alleging a $1.3B deficit impact and transparency failures.

✅ Auditor alleges deficit understated by $1.3B

✅ Dispute over PSAS vs US-style accounting

✅ KPMG support, transparency and co-operation questioned

 

The bad blood between the Ontario government and auditor general bubbled to the surface once again Monday, with the Liberal energy minister downplaying a dispute between the auditor and the Crown corporation that manages the province's electricity market, even as the government pursued legislation to lower electricity rates in the province.

Glenn Thibeault said concerns raised by auditor general Bonnie Lysyk during testimony before a legislative committee last week aren't new and the practices being used by the Independent Electricity System Operator are commonly endorsed by major auditing firms.

"(Lysyk) doesn't like the rate-regulated accounting. We've always said we've relied on the other experts within the field as well, plus the provincial controller," Thibeault said.

#google#

"We believe that we are following public sector accounting standards."

Thibeault said that Ontario Power Generation, Hydro One and many other provinces and U.S. states use the same accounting practices.

"We go with what we're being told by those who are in the field, like KPMG, like E&Y," he said.

But a statement from Lysyk's office Monday disputed Thibeault's assessment.

"The minister said the practices being used by the IESO are common in other jurisdictions," the statement said.

"In fact, the situation with the IESO is different because none of the six other jurisdictions with entities similar to the IESOuse Canadian Public Sector Accounting Standards. Five of them are in the United States and use U.S. accounting standards."

Lysyk said last week that the IESO is using "bogus" accounting practices and her office launched a special audit of the agency late last year after the agency changed their accounting to be more in line with U.S. accounting, following reports of a phantom demand problem that cost customers millions.

Lysyk said the accounting changes made by the IESO impact the province's deficit, understating it by $1.3 billion as of the end of 2017, adding that IESO "stalled" her office when it asked for information and was not co-operative during the audit.

Lysyk's full audit of the IESO is expected to be released in the coming weeks and is among several accounting disputes her office has been engaged in with the Liberal government over the past few years.

Last fall, she accused the government of purposely obscuring the true financial impact of its 25% hydro rate cut by keeping billions in debt used to finance that plan off the province's books. Lysyk had said she would audit the IESO because of its role in the hydro plan's complex accounting scheme.

"Management of the IESO and the board would not co-operate with us, in the sense that they continually say they're co-operating, but they stalled on giving us information," she said last week.

Terry Young, a vice-president with the IESO, said the agency has fully co-operated with the auditor general. The IESO opened up its office to seven staff members from the auditor's office while they did their work.

"We recognize the work that she's doing and to that end we've tried to fully co-operate," he said. "We've given her all of the information that we can."

Young said the change in accounting standards is about ensuring greater transparency in transactions in the energy marketplace.

"It's consistent with many other independent electricity system operators are doing," he said.

Lysyk also criticized IESO's accounting firm, KPMG, for agreeing with the IESO on the accounting standards. She was critical of the firm billing taxpayers for nearly $600,000 work with the IESO in 2017, compared to their normal yearly audit fee of $86,500.

KPMG spokeswoman Lisa Papas said the accounting issues that IESO addressed during 2017 were complex, contributing to the higher fees.

The accounting practices the auditor is questioning are a "difference of professional judgement," she said.

"The standards for public sector organizations such as IESO are principles-based standards and, accordingly, require the exercise of considerable professional judgement," she said in a statement.

"In many cases, there is more than one acceptable approach that is compliant with the applicable standards."

Progressive Conservative energy critic Todd Smith said the government isn't being transparent with the auditor general or taxpayers, aligning with calls for cleaning up Ontario's hydro mess in the sector.

"Obviously, they have some kind of dispute but the auditor's office is saying that the numbers that the government is putting out there are bogus.

Those are her words," he said. "We've always said that we believe the auditor general's are the true numbers for the
province of Ontario."

NDP energy critic Peter Tabuns said the Liberal government has decided to "play with accounting rules" to make its books look better ahead of the spring election, despite warnings that electricity prices could soar if costs are pushed into the future.

Biggest offshore windfarm to start UK supply this week

Hornsea One Offshore Wind Farm delivers first power to the UK grid, scaling renewable energy with 1.2GW capacity, giant offshore turbines, and Yorkshire coast infrastructure to replace delayed nuclear and cut fossil fuel emissions.

 

Key Points

Hornsea One Offshore Wind Farm is a 1.2GW UK project delivering offshore renewable power to about 1 million homes.

✅ 174 turbines over 407 km2; Siemens Gamesa supply chain in the UK

✅ 1.2GW capacity can power ~1m homes; phases scale with 10MW+ turbines

✅ Supports UK grid, replaces delayed nuclear, cuts fossil generation

 

An offshore windfarm on the Yorkshire coast that will dwarf the world’s largest when completed is to supply its first power to the UK electricity grid this week, mirroring advances in tidal electricity projects delivering to the grid as well.

The Danish developer Ørsted, which has installed the first of 174 turbines at Hornsea One, said it was ready to step up its plans and fill the gap left by failed nuclear power schemes.

The size of the project takes the burgeoning offshore wind power sector to a new scale, on a par with conventional fossil fuel-fired power stations.

Hornsea One will cover 407 square kilometres, five times the size of the nearby city of Hull. At 1.2GW of capacity it will power 1m homes, making it about twice as powerful as today’s biggest offshore windfarm once it is completed in the second half of this year.

“The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change,” said Matthew Wright, UK managing director of Ørsted, the world’s biggest offshore windfarm builder.

The power station is only the first of four planned in the area, with a green light and subsidies already awarded to a second stage due for completion in the early 2020s, and interest from Japanese utilities underscoring growing investor appetite.

The first two phases will use 7MW turbines, which are taller than London’s Gherkin building.

But the latter stages of the Hornsea development could use even more powerful, 10MW-plus turbines. Bigger turbines will capture more of the energy from the wind and should lower costs by reducing the number of foundations and amount of cabling firms need to put into the water, with developers noting that offshore wind can compete with gas in the U.S. as costs fall.

Henrik Poulsen, Ørsted’s chief executive, said he was in close dialogue with major manufacturers to use the new generation of turbines, some of which are expected to approach the height of the Shard in London, the tallest building in the EU.

The UK has a great wind resource and shallow enough seabed to exploit it, and could even “power most of Europe if it [the UK] went to the extreme with offshore”, he said.

Offshore windfarms could help ministers fill the low carbon power gap created by Hitachi and Toshiba scrapping nuclear plants, the executive suggested. “If nuclear should play less of a role than expected, I believe offshore wind can step up,” he said.

New nuclear projects in Europe had been “dramatically delayed and over budget”, he added, in comparison to “the strong track record for delivering offshore [wind]”.

The UK and Germany installed 85% of new offshore wind power capacity in the EU last year, according to industry data, with wind leading power across several markets. The average power rating of the turbines is getting bigger too, up 15% in 2018.

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull, part of a web of UK-based suppliers that has sprung up around the growing sector, such as Prysmian UK's land cables supporting grid connections.

Around half of the project’s transition pieces, the yellow part of the structure that connects the foundation to the tower, are made in Teeside. Many of the towers themselves are made by a firm in Campbeltown in the Scottish highlands. Altogether, about half of the components for the project are made in the UK.

Ørsted is not yet ready to bid for a share of a £60m pot of further offshore windfarm subsidies, to be auctioned by the government this summer, but expects the price to reach even more competitive levels than those seen in 2017.

Like other international energy companies, Ørsted has put in place contingency planning in event of a no-deal Brexit – but the hope is that will not come to pass. “We want a Brexit deal that will facilitate an orderly transition out of the union,” said Poulsen.

'Transformative change': Wind-generated electricity starting to outpace coal in Alberta

Alberta wind power surpasses coal as AESO reports record renewable energy feeding the grid, with natural gas conversions, solar growth, energy storage, and decarbonization momentum lowering carbon intensity across Alberta's electricity system.

 

Key Points

AESO data shows wind surpassing coal in Alberta, driven by coal retirements, gas conversions, and growing renewables.

✅ AESO reports wind output above coal several times this week

✅ Coal units retire or convert to natural gas, boosting renewables

✅ Carbon intensity falls; storage and solar improve grid reliability

 

Marking a significant shift in Alberta energy history, wind generation trends provided more power to the province's energy grid than coal several times this week.

According to data from the Alberta Energy System Operator (AESO) released this week, wind generation units contributed more energy to the grid than coal at times for several days. On Friday afternoon, wind farms contributed more than 1,700 megawatts of power to the grid, compared to around 1,260 megawatts from coal stations.

"The grid is going through a period of transformative change when we look at the generation fleet, specifically as it relates to the coal assets in the province," Mike Deising, AESO spokesperson, told CTV News in an interview.

The shift in electricity generation comes as more coal plants come offline in Alberta, or transition to cleaner energy through natural gas generation, including the last of TransAlta's units at the Keephills Plant west of Edmonton.

Only three coal generation stations remain online in the province, at the Genesee plant southwest of Edmonton, as the coal phase-out timeline advances. Less available coal power, means renewable energy like wind and solar make up a greater portion of the grid.

 

EVOLUTION OF THE GRID
"Our grid is changing, and it's evolving," Deising said, adding that more units have converted to natural gas and companies are making significant investments into solar and wind energy.

For energy analyst Kevin Birn with IHS Markit, that trend is only going to continue.

"What we've seen for the last 24 to 36 months is a dramatic acceleration in ambition, policy, and projects globally around cleaner forms of energy or lower carbon forms of energy," Birn said.

Birn, who is also chief analyst of Canadian Oil Markets, added that not only has the public appetite for cleaner energy helped fuel the shift, but technological advancements have made renewables like wind and solar more cost-efficient.

"Alberta was traditionally heavily coal-reliant," he said. "(Now) western Canada has quite a diverse energy base."


LESS CARBON-INTENSIVE
According to Birn, the shift in energy production marks a significant reduction in carbon emissions as Alberta progresses toward its last coal plant closure milestone.

Ten years ago, IHS Markit estimates that Alberta's grid contributed about 900 kilograms of carbon dioxide equivalent per megawatt-hour of energy generation.

"That (figure is) really representing the dominance and role of coal in that grid," Birn said.

Current estimates show that figure is closer to 600 kilograms of CO2 equivalent.

"That means the power you and I are using is less carbon-intensive," Birn said, adding that figure will continue to fall over the next couple of years.


RENEWABLES HERE TO STAY
While many debate whether Alberta's energy is getting clean enough fast enough, Birn believes change is coming.

"It's been a half-decade of incredible price volatility in the oil market which had really dominated this sector and region," the analyst said.

"When I think of the future, I see the power sector building on large-scale renewables, which means decarbonization, and that provides an opportunity for those tech companies looking for clean energy places to land facilities."

Coal and natural gas are considered baseline assets by the AESO, where generation capacity does not shift dramatically, though some utilities report declining coal returns in other markets.

"Wind is a variable resource. It will generate when the wind is blowing, and it obviously won't when the wind is not," Deising said. "Wind and solar can ramp quickly, but they can drop off quite quickly, and we have to be prepared.

"We factor that into our daily planning and assessments," he added. "We follow those trends and know where the renewables are going to show up on the system, how many renewables are going to show up."

Deising says one wind plant in Alberta currently has an energy storage capacity to preserve renewably generated electricity during summer demand records and peak hours as needed. As the technology becomes more affordable, he expects more plants to follow suit.

"As a system operator, our job is to make sure as (the grid) is evolving we can continue to provide reliable power to Albertans at every moment every day," Deising said. "We just have to watch the system more carefully."

Alberta shift from coal to cleaner energy

Alberta Coal-to-Gas Transition will retire coal units, convert plants to natural gas, boost renewables, and affect electricity prices, with policy tools like a price cap and carbon tax shaping the power market.

 

Key Points

Shift retiring coal units and converting to natural gas and renewables, targeting coal elimination by 2030.

✅ TransAlta retires Sundance coal unit; more units convert to gas.

✅ Forward prices seen near $40 to low $50/MWh in 2018.

✅ 6.8-cent cap shields consumers; carbon tax backstops costs.

 

The turn of the calendar to 2018 saw TransAlta retire one of its coal power generating units at its Sundance plant west of Edmonton and mothball another as it begins the transition to cleaner sources of energy across Alberta.

The company will say goodbye to three more units over the next year and a half to prepare them for conversion to natural gas.

This is part of a fundamental shift in Alberta, which will see coal power retired ahead of schedule by 2030, replaced by a mix of natural gas and renewable sources.

“We’re going to see that transition continue right up from now until 2030, and likely beyond 2030 as wind generation starts to outpace coal and new technologies become available.”

Coal has long been the backbone of Alberta’s grid, currently providing nearly 40 per cent of the provinces power. Analysts believe removing it will come with a cost to consumers, according to a report on coal phase-out costs published recently.

“The open question over the next couple of years is whether they’re going to inch up gradually, or whether they’re going to inch up like they did in 2012 and 2013, by having periods of very high power prices.”

Albertans are currently paying historically low power prices, with generation costs last year averaging below $23/MWh, less than half of the average of the past 10 years.

A report released in mid-December by electricity consultant firm EDC Associates showed forward prices moving from the $40/MWh in the first three months of 2018, to the low $50/MWh range.

“The forwards tend to take several weeks to fully react to announcements, so its anticipated that prices will continue to gradually track upwards over the coming weeks,” the report reads.

The NDP government has taken steps to protect consumers against price surges. Last spring, a price cap of 6.8 cents/MWh was put in place until the spring of 2021, with any cost above that to be covered by carbon tax revenue.
