LARGE-SCALE ENERGY PROJECTS UNDERWAY IN NY

Georgia Electricity Imports October 2017 surged as hydropower output fell and thermal power plants underperformed; ESCO balanced demand via low-cost imports, mainly from Azerbaijan, amid rising tariffs, kWh consumption growth, and a widening generation-consumption gap.

Key Points

They mark a record import surge due to costly local generation, lower hydropower, ESCO balancing costs, and rising demand.

✅ Imports rose 832% YoY to 157 mln kWh, mainly from Azerbaijan

✅ TPP output fell despite capacity; only low-tariff plants ran

✅ Balancing price 13.8 tetri/kWh signaled costly domestic PPAs

In October 2017, Georgian power plants generated 828 mln. KWh of electricity, marginally up (+0.79%) compared to September. Following the traditional seasonal pattern and amid European concerns over dispatchable power shortages affecting markets, the share of electricity produced by renewable sources declined to 71% of total generation (87% in September), while thermal power generation’s share increased, accounting for 29% of total generation (compared to 13% in September). When we compare last October’s total generation with the total generation of October 2016, however, we observe an 8.7% decrease in total generation (in October 2016, total generation was 907 mln. kWh). The overall decline in generation with respect to the previous year is due to a simultaneous decline in both thermal power and hydro power generation. 

Consumption of electricity on the local market in the same period was 949 mln. kWh (+7% compared to October 2016, and +3% with respect to September 2017), and reflected global trends such as India's electricity growth in recent years. The gap between consumption and generation increased to 121 mln. kWh (15% of the amount generated in October), up from 100 mln. kWh in September. Even more importantly, the situation was radically different with respect to the prior year, when generation exceeded consumption.

The import figure for October was by far the highest from the last 12 years (since ESCO was established), occurring as Ukraine electricity exports resumed regionally, highlighting wider cross-border dynamics. In October 2017, Georgia imported 157 mln. kWh of electricity (for 5.2 ¢/kWh – 13 tetri/kWh). This constituted an 832% increase compared to October 2016, and is about 50% larger than the second largest import figure (104.2 mln. kWh in October 2014). Most of the October 2017 imports (99.6%) came from Azerbaijan, with the remaining 0.04% coming from Russia.

The main question that comes to mind when observing these statistics is: why did Georgia import so much? One might argue that this is just the result of a bad year for hydropower generation and increased demand. This argument, however, is not fully convincing. While it is true that hydropower generation declined and demand increased, the country’s excess demand could have been easily satisfied by its existing thermal power plants, even as imported coal volumes rose in regional markets. Instead of increasing, however, the electricity coming from thermal power plants declined as well. Therefore, that cannot be the reason, and another must be found. The first that comes to mind is that importing electricity may have been cheaper than buying it from local TPPs, or from other generators selling electricity to ESCO under power purchase agreements (PPAs). We can test the first part of this hypothesis by comparing the average price of imported electricity to the price ceiling on the tariff that TPPs can charge for the electricity they sell. Looking at the trade statistics from Geostat, the average price for imported electricity in October 2017 remained stable with respect to the same month of the previous year, at 5.2 ¢ (13 tetri) per kWh. Only two thermal power plants (Gardabani and Mtkvari) had a price ceiling below 13 tetri per kWh. Observing the electricity balance of Georgia, we see that indeed more than 98% of the electricity generated by TPPs in October 2017 was generated by those two power plants.

What about other potential sources of electricity amid Central Asia's power shortages at the time? To answer this question, we can use the information derived from the weighted average price of balancing electricity. Why balancing electricity? Because it allows us to reconstruct the costs the market operator (ESCO) faced during the month of October to make sure demand and supply were balanced, and it allows us to gain an insight about the price of electricity sold through PPAs.

ESCO reports that the weighted average price of balancing electricity in October 2017 was 13.8 tetri/kWh, (25% higher than in October 2016, when it was below the average weighted cost of imports – 11 vs. 13 – and when the quantity of imported electricity was substantially smaller). Knowing that in October 2017, 61% of balancing electricity came from imports, while 39% came from hydropower and wind power plants selling electricity to ESCO under their PPAs, we can deduce that in this case, internal generation was (on average) also substantially more expensive than imports. Therefore, the high cost of internally generated electricity, rather than the technical impossibility of generating enough electricity to satisfy electricity demand, indeed appears to be one the main reasons why electricity imports spiked in October 2017.

Smart solar inverters anchor DER communications and control, meeting IEEE 1547 and California Rule 21 for volt/VAR, reactive power, and ride-through, expanding hosting capacity and enabling grid services via secure real-time telemetry and commands.

Key Points

Smart solar inverters use IEEE 1547, volt/VAR and reactive power to stabilize circuits and integrate DER safely.

✅ Meet IEEE 1547, Rule 21 ride-through and volt/VAR functions

✅ Support reactive power to manage voltage and hosting capacity

✅ Enable utility communications, telemetry, and grid services

Advanced solar inverters could be one of the biggest distributed energy resource communications and control points out there someday. With California now requiring at least early-stage “smart” capabilities from all new solar projects — and a standards road map for next-stage efforts like real-time communications and active controls — this future now has a template.

There are still a lot of unanswered questions about how smart inverters will be used.

That was the consensus at Intersolar this week, where experts discussed the latest developments on the U.S. smart solar inverter front. After years of pilot projects, multi-stakeholder technical working groups, and slow and steady standards development, solar smart inverters are finally starting to hit the market en masse — even if it’s not yet clear just what will be done with them once they’re installed.

“From the technical perspective, the standards are firm,” Roger Salas, distribution engineering manager for Southern California Edison, said. In September of last year, his utility started requiring that all new solar installations come with “Phase 1" advanced inverter functionality, as defined under the state’s Rule 21.

Later this month, it’s going to start requiring “reactive power priority” for these inverters, and in February 2019, it’s going to start requiring that inverters support the communications capabilities described in “Phase 2,” as well as some more advanced “Phase 3” capabilities.

Increasing hosting capacity: A win-win for solar and utilities

Each of these phases aligns with a different value proposition for smart inverters. The first phase is largely preventative, aimed at solving the kinds of problems that have forced costly upgrades to how inverters operate in solar-heavy Germany and Hawaii.

The key standard in question in the U.S. is IEEE 1547, which sets the rules for what grid-connected DERs must do to stay safe, such as trip offline when the grid goes down, or avoid overloading local transformers or circuits.

The old version of the standard, however, had a lot of restrictive rules on tripping off during relatively common voltage excursions, which could cause real problems on circuits with a lot of solar dropping off all at once.

Phase 1 implementation of IEEE 1547 is all about removing these barriers, Salas said. “They need to be stable, they need to be connected, they need to be able to support the grid.”

This should increase hosting capacity on circuits that would have otherwise been constrained by these unwelcome behaviors, he said.

Reactive power: Where utility and solar imperatives collide

The old versions of IEEE 1547 also didn’t provide rules for how inverters could use one of their more flexible capabilities: the ability to inject or absorb reactive power to mitigate voltage fluctuations, including those that may be caused by the PV itself. The new version opens up this capability, which could allow for an active application of reactive power to further increase hosting capacity, as well as solve other grid edge challenges for utilities.

But where utilities see opportunity, the solar industry sees a threat. Every unit of reactive power comes at the cost of a reduction in the real power output of solar inverters — and almost every solar installation out there is paid based on the real power it produces.

“If you’re tasked to do things that rob your energy sales, that will reduce compensation,” noted Ric O'Connell, executive director of the Oakland, Calif.-based GridLab. “And a lot of systems have third-party owners — the Sunruns, the Teslas — with growing Powerwall fleets — that have contracts, performance guarantees, and they want to get those financed. It’s harder to do that if there’s uncertainty in the future with curtailment."

“That’s the bottleneck right now,” said Daniel Munoz-Alvarez, a GTM Research grid edge analyst. “As we develop markets on the retail end for ...volt/VAR control to be compensated on the grid edge and that is compensated back to the customer, then the customer will be more willing to allow the utility to control their smart inverters or to allow some automation.”

But first, he said, “We need some agreed-upon functions.”

The future: Communications, controls and DER integration

The next stage of smart inverter functionality is establishing communications with the utility. After that, utilities will be able use them to monitor key DER data, or issue disconnect and reconnect commands in emergencies, as well as actively orchestrate other utility devices and systems through emerging virtual power plant strategies across their service areas.

This last area is where Salas sees the greatest opportunity to putting mass-market smart solar inverters to use. “If you want to maximize the DERs and what they can do, the need information from the grid. And DERs provide operational and capability information to the utility.”

Inverter makers have already been forced by California to enable the latest IEEE 1547 capabilities into their existing controls systems — but they are clearly embracing the role that their devices can play on the grid as well. Microinverter maker Enphase leveraged its work in Hawaii into a grid services business, seeking to provide data to utilities where they already had a significant number of installations. While Enphase has since scaled back dramatically, its main rival SolarEdge has taken up the same challenge, launching its own grid services arm earlier this summer.

Inverters have been technically capable of doing most of these things for a long time. But utilities and regulators have been waiting for the completion of IEEE 1547 to move forward decisively. Patrick Dalton, senior engineer for Xcel Energy, said his company’s utilities in Colorado and Minnesota are still several years away from mandating advanced inverter capabilities and are waiting for California’s energy transition example in order to choose a path forward.

In the meantime, it’s possible that Xcel's front-of-meter volt/VAR optimization investments in Colorado, including grid edge devices from startup Varentec, could solve many of the issues that have been addressed by smart inverter efforts in Hawaii and California, he noted.

The broader landscape for rolling out smart inverters for solar installations hasn’t changed much, with Hawaii and California still out ahead of the pack, while territories such as Puerto Rico microgrid rules evolve to support resilience. Arizona is the next most important state, with a high penetration of distributed solar, a contentious policy climate surrounding its proper treatment in future years, and a big smart inverter pilot from utility Arizona Public Service to inform stakeholders.

All told, eight separate smart inverter pilots are underway across eight states at present, according to GTM Research: Pacific Gas & Electric and San Diego Gas & Electric in California; APS and Salt River Project in Arizona; Hawaiian Electric in Hawaii; Duke Energy in North Carolina; Con Edison in New York; and a three-state pilot funded by the Department of Energy’s SunShot program and led by the Electric Power Research Institute.

FERC Rejects Trump Coal Plan, denying subsidies for coal-fired and nuclear plants as energy policy shifts toward natural gas and renewables, citing no grid reliability threat and warning about electricity prices and market impacts.

Key Points

FERC unanimously rejected subsidies for coal and nuclear plants, finding no grid reliability risk from retirements.

✅ Unanimous FERC vote rejects coal and nuclear compensation

✅ Cites no threat to grid reliability from plant retirements

✅ Opponents warned subsidies would distort power markets and prices

A decision by an independent energy agency to reject the Trump administration’s electricity pricing plan to bolster the coal industry could lead to more closures of coal-fired power plants and the loss of thousands of jobs, a top coal executive said Tuesday.

Robert Murray, CEO of Ohio-based Murray Energy Corp., called the action by the Federal Energy Regulatory Commission “a bureaucratic cop-out” that will raise the cost of electricity and jeopardize the reliability and security of the nation’s electric grid.

“While FERC commissioners sit on their hands and refuse to take the action directed by Energy Secretary Rick Perry and President Donald Trump, the decommissioning of more coal-fired and nuclear plants could result, further jeopardizing the reliability, resiliency and security of America’s electric power grids,” Murray said. “It will also raise the cost of electricity for all Americans.”

The five-member energy commission voted unanimously Monday to reject Trump’s plan to reward nuclear and coal-fired power plants for adding reliability to the nation’s power grid. The plan would have made the plants eligible for billions of dollars in government subsidies and help reverse a tide of bankruptcies and loss of market share suffered by the once-dominant coal industry as utilities' shift to natural gas and renewable energy continues.

The Republican-controlled commission said there’s no evidence that any past or planned retirements of coal-fired power plants pose a threat to reliability of the nation’s electric grid.

Murray disputed that and said the recent cold snap that hit the East Coast showed coal’s value, as power users in the Southeast were asked to cut back on electricity usage because of a shortage of natural gas. “If it were not for the electricity generated by our nation’s coal-fired and nuclear power plants, we would be experiencing massive brownouts risk and blackouts in this country,” he said.

Murray Energy is the largest privately owned coal company in the United States, with mining operations in Ohio, Illinois, Kentucky, Utah and West Virginia. Robert Murray, a Trump friend and political supporter, has been pushing hard for federal assistance for his industry. The Associated Press reported last year that Murray asked the Trump administration to issue an emergency order protecting coal-fired power plants from closing. Murray warned that failure to act could cause thousands of coal miners to be laid off and force his largest customer, Ohio-based FirstEnergy Solutions, into bankruptcy.

Perry ultimately rejected Murray’s request, but later asked energy regulators to boost coal and nuclear plants as the administration moved to replace the Clean Power Plan with a more limited approach.

The plan drew widespread opposition from business and environmental groups that frequently disagree with each other, even as some coal and business interests backed the EPA's Affordable Clean Energy rule in court.

Jack Gerard, president and CEO of the American Petroleum Institute, said Tuesday that the Trump plan was “far too narrow” in its focus on power sources that maintain a 90-day fuel supply.

API, the largest lobbying group for oil and gas industry, supports coal and other energy sources, Gerard said, “but we should not put our eggs in an individual basket defined as a 90-day fuel supply (while) unnecessarily intervening in private markets.”

BC Hydro Time-of-Use Rates propose off-peak credits and peak surcharges, with 5 cent/kWh differentials, encouraging demand shifting, EV charging at night, and smart meter adoption, pending BC Utilities Commission review in an optional opt-in program.

Key Points

Optional pricing that credits 5 cents/kWh off-peak and adds 5 cents/kWh during 4-9 p.m. peak to encourage load shifting.

✅ Off-peak credit: 11 p.m.-7 a.m., 5 cents/kWh savings

✅ Peak surcharge: 4-9 p.m., additional 5 cents/kWh

✅ Opt-in only; BCUC review; suits EV charging and flexible loads

BC Hydro is looking to charge customers less for electricity during off peak hours and more during the busiest times of the day, reflecting holiday electricity demand as well.

The BC Utilities Commission is currently reviewing the application that if approved would see customers receive a credit of 5 cents per kilowatt hour for electricity used from 11 p.m. to 7 a.m.

Customers would be charged an additional 5 cents per kWh for electricity used during the on-peak period from 4 p.m. to 9 p.m., and in Ontario, there were no peak-rate cuts for self-isolating customers during early pandemic response.

There would be no credit or additional charge will be applied to usage during the off-peak period from 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m.

“We know the way our customers are using power is changing and they want more options,” BC Hydro spokesperson Susie Rieder said.

“It is optional and we know it may not work for everyone.”

For example, if a customer has an electric vehicle it will be cheaper to plug the car in after 9 p.m., similar to Ontario's ultra-low overnight plan offerings, rather than immediately after returning home from a standard work day.

If approved, the time of use rates would only apply to customers who opt in to the program, whereas Ontario provided electricity relief during COVID-19.

During the pandemic, Ontario extended off-peak electricity rates to help households and small businesses.

The regulatory review process is expected to take about one year.

Other jurisdictions, including Ontario's ultra-low overnight pricing, currently offer off peak rates. One of the challenges is that consumers change in hopes of altering their behaviour, but in reality, end up paying more.

“The cheapest electrical grid system is one with consistent demand and the issue of course is our consumption is not flat,” energyrates.ca founder Joel MacDonald said.

“There is a 5 cent reduction in off peak times, there is a 5 cent increase in peak times, you would have to switch 50 per cent of your load.”

Cooperative Energy bond rating upgrade signals lower debt costs as Fitch lifts GO Zone Bonds to A, reflecting Kemper exit, shift to owned generation, natural gas, and renewable energy for co-op members and borrowing rates.

Key Points

Fitch raised Cooperative Energy's GO Zone Bonds to A, cutting debt costs after Kemper exit and shift to natural gas.

✅ Fitch upgrades 2009A GO Zone Bonds from A- to A.

✅ Kemper divestment reduced risk and exposure to coal.

✅ Shift to owned generation, natural gas, renewables lowers costs.

Cooperative Energy and its 11 co-op members will see lower debt costs on $35.4 million bond; similar to regional utilities offering one-time bill decreases for customers recently.

Bailing out of its 15 percent ownership stake in Mississippi Power’s Kemper gasification plant, amid debates over coal and nuclear subsidies in federal policy, has helped Hattiesburg-based Cooperative Energy gain a ratings upgrade on a $35.4 million bond issue.

The electric power co-op, which changed its name to Cooperative Energy from South Mississippi Electric Power Association in November, received a ratings upgrade from A- to A for its 2009 2009A Mississippi Business Finance Corporation Gulf Opportunity Zone Bonds, even as other utilities announced bill reductions for customers during 2020.

“This rating upgrade reflects the success of our strategy to move from purchased power to owned generation resources, and from coal to natural gas and renewable energy as clean energy priorities gain traction,” said Cooperative Energy President/CEO Jim Compton in a press release.  “The result for our members is lower borrowing costs and more favorable rates.”

An “A” rating from Fitch designates the bond issue as “near premium quality,” a status noted as utilities adapted to pandemic-era electricity demand trends nationwide.

Germany Energy Demand Decline reflects economic stagnation, IEA forecasts, and the Energiewende, as industrial output slips and efficiency gains, renewables growth, and cost-cutting reduce fossil fuel use while reshaping sustainability and energy security.

Key Points

A projected 7% drop in German energy use driven by industrial slowdown, efficiency gains, and renewables expansion.

✅ IEA projects up to 7% demand drop in the next year

✅ Industrial slowdown and efficiency programs cut consumption

✅ Energiewende shifts mix to wind, solar, and less fossil fuel

Germany is on the verge of experiencing a significant decline in energy demand, with forecasts suggesting that usage could hit a record low as the country grapples with economic stagnation. This shift highlights not only the immediate impacts of sluggish economic growth but also broader trends in energy consumption, Europe's electricity markets, sustainability, and the transition to renewable resources.

Recent data indicate that Germany's economy is facing substantial challenges, including high inflation and reduced industrial output. As companies struggle to maintain profitability amid nearly doubled power prices and rising costs, many have begun to cut back on energy consumption. This retrenchment is particularly pronounced in energy-intensive sectors such as manufacturing and chemical production, which are crucial to Germany's export-driven economy.

The International Energy Agency (IEA) has projected that German energy demand could decline by as much as 7% in the coming year, a stark contrast to the trends seen in previous decades. This decline is primarily driven by a combination of factors, including reduced industrial activity, increased energy efficiency measures, and a shift toward alternative energy sources, as well as mounting pressures on local utilities to stay solvent. The current economic landscape has led businesses to prioritize cost-cutting measures, including energy efficiency initiatives aimed at reducing consumption.

In the context of these developments, Germany’s energy transition—known as the "Energiewende"—is becoming increasingly significant. The country has made substantial investments in renewable energy sources such as wind, solar, and biomass in recent years. As energy efficiency improves and the share of renewables in the energy mix rises, traditional fossil fuel consumption has begun to wane. This transition is seen as both a response to climate change and a strategy for energy independence, particularly in light of geopolitical tensions and Europe's wake-up call to ditch fossil fuels across the continent.

However, the current stagnation presents a paradox for the German energy sector. While lower energy demand may ease some pressures on supply and prices, it also raises concerns about the long-term viability of investments in renewable energy infrastructure, even as debates continue over electricity subsidies for industry to support competitiveness. The economic slowdown has the potential to derail progress made in reducing carbon emissions and achieving energy targets, particularly if it leads to decreased investment in green technologies.

Another layer to this issue is the potential impact on employment within the energy sector. As energy demand decreases, there may be a ripple effect on jobs tied to traditional energy production and even in renewable energy sectors if investment slows. Policymakers are now tasked with balancing the immediate need for economic recovery, illustrated by the 200 billion-euro energy price shield, with the longer-term goal of achieving sustainability and energy security.

The effects of the stagnation are also being felt in the residential sector. As households face increased living costs and rising heating and electricity costs, many are becoming more conscious of their energy consumption. Initiatives to improve home energy efficiency, such as better insulation and energy-efficient appliances, are gaining traction among consumers looking to reduce their utility bills. This shift toward energy conservation aligns with broader national goals of reducing overall energy consumption and carbon emissions.

Despite the challenges, there is a silver lining. The current situation offers an opportunity for Germany to reassess its energy strategies and invest in technologies that promote sustainability while also addressing economic concerns. This could include increasing support for research and development in green technologies, enhancing energy efficiency programs, and incentivizing businesses to adopt cleaner energy practices.

Furthermore, Germany’s experience may serve as a case study for other nations grappling with similar issues. As economies around the world face the dual pressures of recovery and sustainability, the lessons learned from Germany’s current energy landscape could inform strategies for balancing these often conflicting priorities.

In conclusion, Germany is poised to witness a historic decline in energy demand as economic stagnation takes hold. While this trend poses challenges for the energy sector and economic growth, it also highlights the importance of sustainability and energy efficiency in shaping the future. As the nation navigates this complex landscape, the focus will need to be on fostering innovation and investment that aligns with both immediate economic needs and long-term environmental goals. The path forward will require a careful balancing act, but with the right strategies, Germany can emerge as a leader in sustainable energy practices even in challenging times.
