Canadian Wal-Marts Dim Lighting to Conserve Energy

Germany's Joint Onshore Wind and Solar Tender invites 200 MW bids in an EEG auction, with PV and onshore wind competing on price per MWh, including grid integration costs and network fees under BNA rules.

Key Points

A BNA-run 200 MW EEG auction where PV and onshore wind compete on price per MWh, including grid integration costs.

✅ 200 MW cap; minimum project size 750 kW

✅ Max subsidy 87.50 per MWh; bids include network costs

✅ Solar capped at 10-20 MW; wind requires prior approval

Germany's Federal Network Agency (BNA) has launched its second joint onshore wind and solar photovoltaic (PV) tender, with a total capacity of 200 MW.

A maximum guaranteed subsidy payment has been set at 87.50 per MWh for both energy sources, which BNA says will have to compete against each other for the lowest price of electricity. According to auction rules, all projects must have a minimum of 750 kW.

The auction is due to be completed on 2 November.

The network regulator has capped solar projects at 10 MW, though this has been extended to 20 MW in some districts, amid calls to remove barriers to PV at the federal level. Onshore wind projects did not receive any such restrictions, though they require approval from Federal Immission Control three weeks prior to the bid date of 11 Octobe

Bids also require network and system integration costs to be included, and similar solicitations have been heavily subscribed, as an over-subscribed Duke Energy solar solicitation in the US market illustrates.

According to Germanys Renewable Energy Act (EEG), two joint onshore wind and solar auctions must take place each year between 2018 and 2021. After this, the government will review the scheme and decide whether to continue it beyond 2021.

The first tender, conducted in April, saw the entire 200 MW capacity given to solar PV projects, reflecting a broader solar power boost in Germany during the energy crisis. Of the 32 contracts awarded, value varied from 39.60 per MWh to 57.60 per MWh. Among the winning bids were five projects in agricultural and grassland sites in Bavaria, totalling 31 MW, and three in Baden-Wrttemberg at 17 MW.

According to the Agency, the joint tender scheme was initiated in an attempt to determine the financial support requirements for wind and solar in technology-specific auctions, however, solar powers sole win in the April auction meant it was met with criticism, even as clean energy accounts for 50% of Germany's electricity today.

The heads of the Federal Solar Industry Association (BSW-Solar) and German Wind Energy Association (BWE) saying the joint tender scheme is unsuitable for the build-out of the two technologies.

A BWE spokesman previously stressed the companys rejection of competition between wind and solar, saying: It is not clear how this could contribute to an economically meaningful balanced energy mix,

Technologies that are in various stages of development must not enter into direct competition with each other. Otherwise, innovation and development potential will be compromised.

Similarly, BSW-Solar president Carsten Krnig said: We are happy for the many solar winners, but consider the experiment a failure. The auction results prove the excellent price-performance ratio of new solar power plants, as solar-plus-storage is cheaper than conventional power in Germany, but not the suitability of joint tenders.

Southeast Alaska Energy Projects advance hydroelectric, biomass, and heat pumps, displacing diesel via grants. Inside Passage Electric Cooperative and Alaska Energy Authority support Kake, Hoonah, Ketchikan with wood pellets, feasibility studies, and rate relief.

Key Points

Programs using hydro, biomass, and heat pumps to cut diesel use and lower electricity costs in Southeast Alaska.

✅ Hydroelectric at Gunnuk Creek to replace diesel in Kake

✅ Biomass and wood pellets displacing fuel oil in facilities

✅ Free feasibility studies; heat pumps where economical

New projects are under development throughout the region to help reduce energy costs for Southeast Alaska residents. A panel presented some of those during last week’s Southeast Conference annual fall meeting in Ketchikan.

Jodi Mitchell is with Inside Passage Electric Cooperative, which is working on the Gunnuk Creek hydroelectric project for Kake. IPEC is a non-profit, she said, with the goal of reducing electric rates for its members.

The Gunnuk Creek project will be built at an existing dam.

“The benefits for the project will be, of course, renewable energy for Kake. And we estimate it will save about 6.2 million gallons over its 50-year life,” she said. “Although, as you heard earlier, these hydro projects last forever.”

The gallons saved are of diesel fuel, which currently is used to power generators for electricity, though in places with limited options some have even turned to new coal plants to keep the lights on.

IPEC operates other hydro projects in Klukwan and Hoonah. Mitchell said they’re looking into future projects, one near Angoon and another that would add capacity to the existing Hoonah project, even as an independent power project in British Columbia is in limbo.

Mitchell said they fund much of their work through grants, which helps keep electric rates at a reasonable level.

Devany Plentovich with the Alaska Energy Authority talked about biomass projects in the state. She said the goal is to increase wood energy use in Alaska, even as some advocates call for a reduction in biomass electricity in other regions.

“We offer any community, any entity, a free feasibility study to see if they have a potential heating system in their community,” she said. “We do advocate for wood heating, but we are trying to get a community to pick the best heating technology for their situation, including options that use more electricity for heat when appropriate. So in a lot of situations, our consultants will give you the economics on a wood heating system but they’ll also recommend maybe you should look at heat pumps or look at waste energy.”

Plentovich said they recently did a study for Ketchikan’s Holy Name Church and School. The result was a recommendation for a heat pump rather than wood.

But, she said, wood energy is on the rise, and utilities elsewhere are increasing biomass for electricity as well. There are more than 50 systems in the state displacing more than 500,000 gallons of fuel oil annually. Those include systems on Prince of Wales Island and in Ketchikan.

Ketchikan recently experienced a supply issue, though. A local wood-pellet manufacturer closed, which is a problem for the airport and the public library, among other facilities that use biomass heaters.

Karen Petersen is the biomass outreach coordinator for Southeast Conference. She said this opens up a great opportunity for someone.

“Devany and I are working on trying to find a supplier who wants to go into the pellet business,” she said. “Probably importing initially, and then converting over to some form of manufacturing once the demand is stabilized.”

So, Petersen said, if anyone is interested in this entrepreneurial opportunity, contact her through Southeast Conference for more information.

Nuclear Power for Net-Zero Grids anchors reliable baseload, integrating renewables with grid stability as solar, wind, and battery storage scale. Advanced reactors complement hydropower, curb natural gas reliance, and accelerate deep decarbonization of electricity systems.

Key Points

Uses nuclear baseload and advanced reactors to stabilize power grids and integrate higher shares of variable renewables.

✅ Provides firm, zero-carbon baseload for renewable-heavy grids

✅ Reduces natural gas dependence and peaker emissions

✅ Advanced reactors enhance safety, flexibility, and cost

Declining solar, wind, and battery technology costs are helping to grow the share of renewables in the world’s power mix to the point that governments are pledging net-zero emission electricity generation in two to three decades to fight global warming.

Yet, electricity grids will continue to require stable baseload to incorporate growing shares of renewable energy sources and ensure lights are on even when the sun doesn’t shine, or the wind doesn’t blow. Until battery technology evolves enough—and costs fall far enough—to allow massive storage and deployment of net-zero electricity to the grid, the systems will continue to need power from sources other than solar and wind.

And these will be natural gas and nuclear power, regardless of concerns about emissions from the fossil fuel natural gas and potential disasters at nuclear power facilities such as the ones in Chernobyl or Fukushima.

As natural gas is increasingly considered as just another fossil fuel, nuclear power generation provides carbon-free electricity to the countries that have it, even as debates over nuclear power’s outlook continue worldwide, and could be the key to ensuring a stable power grid capable of taking in growing shares of solar and wind power generation.

The United States, where nuclear energy currently provides more than half of the carbon-free electricity, is supporting the development of advanced nuclear reactors as part of the clean energy strategy.

But Europe, which has set a goal to reach carbon neutrality by 2050, could find itself with growing emissions from the power sector in a decade, as many nuclear reactors are slated for decommissioning and questions remain over whether its aging reactors can bridge the gap. The gap left by lost nuclear power is most easily filled by natural gas-powered electricity generation—and this, if it happens, could undermine the net-zero goals of the European Union (EU) and the bloc’s ambition to be a world leader in the fight against climate change.

U.S. Power Grid Will Need Nuclear For Net-Zero Emissions

A 2020 report from the University of California, Berkeley, said that rapidly declining solar, wind, and storage prices make it entirely feasible for the U.S. to meet 90 percent of its power needs from zero-emission energy sources by 2035 with zero increases in customer costs from today’s levels.

Still, natural gas-fired generation will be needed for 10 percent of America’s power needs. According to the report, in 2035 it would be possible that “during normal periods of generation and demand, wind, solar, and batteries provide 70% of annual generation, while hydropower and nuclear provide 20%.” Even with an exponential rise in renewable power generation, the U.S. grid will need nuclear power and hydropower to be stable with such a large share of solar and wind.

The U.S. Backs Advanced Nuclear Reactor Technology

The U.S. Department of Energy is funding programs of private companies under DOE’s new Advanced Reactor Demonstration Program (ARDP) to showcase next-gen nuclear designs for U.S. deployment.

“Taking leadership in advanced technology is so important to the country’s future because nuclear energy plays such a key role in our clean energy strategy,” U.S. Secretary of Energy Dan Brouillette said at the end of December when DOE announced it was financially backing five teams to develop and demonstrate advanced nuclear reactors in the United States.

“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” Secretary Brouillette said.

According to Washington DC-based Nuclear Energy Institute (NEI), a policy organization of the nuclear technologies industry, nuclear energy provides nearly 55 percent of America’s carbon-free electricity. That is more than 2.5 times the amount generated by hydropower, nearly 3 times the amount generated by wind, and more than 12 times the amount generated by solar. Nuclear energy can help the United States to get to the deep carbonization needed to hit climate goals.

Europe Could See Rising Emissions Without Nuclear Power

While the United States is doubling down on efforts to develop advanced and cheaper nuclear reactors, including microreactors and such with new types of technology, Europe could be headed to growing emissions from the electricity sector as nuclear power facilities are scheduled to be decommissioned over the next decade and Europe is losing nuclear power just when it really needs energy, according to a Reuters analysis from last month.

In many cases, it will be natural gas that will come to the rescue to power grids to ensure grid stability and enough capacity during peak demand because solar and wind generation is variable and dependent on the weather.

For example, Germany, the biggest economy in Europe, is boosting its renewables targets, but it is also phasing out nuclear by next year, amid a nuclear option debate over climate strategy, while its deadline to phase out coal-fired generation is 2038—more than a decade later compared to phase-out plans in the UK and Italy, for example, where the deadline is the mid-2020s.

The UK, which left the EU last year, included support for nuclear power generation as one of the ten pillars in ‘The Ten Point Plan for a Green Industrial Revolution’ unveiled in November.

The UK’s National Grid has issued several warnings about tight supply since the fall of 2020, due to low renewable output amid high demand.

“National Grid’s announcement underscores the urgency of investing in new nuclear capacity, to secure reliable, always-on, emissions-free power, alongside other zero-carbon sources. Otherwise, we will continue to burn gas and coal as a fallback and fall short of our net zero ambitions,” Tom Greatrex, Chief Executive of the Nuclear Industry Association, said in response to one of those warnings.

But it’s in the UK that one major nuclear power plant project has notoriously seen a delay of nearly a decade—Hinkley Point C, originally planned in 2007 to help UK households to “cook their 2017 Christmas turkeys”, is now set for start-up in the middle of the 2020s.

Nuclear power development and plant construction is expensive, but it could save the plans for low-carbon emission power generation in many developed economies, including in the United States.

Denmark 2019 electricity CO2 intensity shows record-low emissions as renewable energy surges, wind power dominates, offshore wind expands, and coal phase-out accelerates Denmark's energy transition and grid decarbonization, driven by higher CO2 prices and flexibility.

Key Points

It is 135 g CO2/kWh, a record low enabled by wind power growth, offshore wind, and a sharp coal decline.

✅ Average emissions fell to 135 g CO2/kWh, the lowest on record

✅ Wind and solar supplied 49.9% of national electricity use

✅ Coal consumption dropped 46% as CO2 allowance prices rose

Danish electricity producers set a new green record in 2019, when an average produced kilowatt-hour emitted 135 gr CO2 / kWh.

It is the lowest CO2 emission ever measured in Denmark and about one-seventh of what the electricity producers emitted in 1990.

Never has a kilowatt-hour produced emitted as little CO2 as it did in 2019. And that's according to Energinet's recently published annual Environmental Report on Danish electricity generation and cogeneration, two primary causes.

One reason is that more green power has been produced because the Horns Rev 3 offshore wind farm, which can produce electricity for 425,000 households, was commissioned in 2019. The other is that Danish coal consumption fell by 46 percent from 2018 to 2019, as coal phase-out plans gathered pace across the sector. the dramatic decline in coal consumption is partly due a significant increase in the price of CO2 quotas, and thus also the price of CO2 emissions.

'Historically, 135 gr CO2 / kWh is a really, really low figure, showing the impressive green travel that the Danish electricity system has been on. In 1990, a kilowatt-hour produced emitted over 1000 grams of CO2, ie about seven times as much as today, 'says Hanne Storm Edlefsen, area manager in Energinet Power Systems Responsibility.

Wind energy is the dominant form of electricity generation in Denmark, a pattern the UK wind beat coal in 2016 when shifting away from fossil fuels.

17.1 TWh. Danish wind turbines and solar cells generated so much electricity in 2019, corresponding to 49.9 per cent. of Danish electricity consumption, reflecting broader EU wind and solar growth trends as well. An increase of 15 per cent. The wind turbines alone produced 16 TWh, which is not only a new green record, but also puts a thick line that wind energy is by far the most dominant form of electricity generation in Denmark.

'Thanks to our large wind resources, turbines are by far the largest supplier of renewable energy in Denmark, and this will be for many years to come. The large price drop in new wind energy in recent years - for both onshore and offshore winds - will ensure that wind energy will drive a large part of the growth in renewable energy in the coming years, as new wind generation records are set in markets like the UK, 'says Soren Klinge, electricity market manager at Wind Denmark.

Conversely, total electricity generation from fossil and bio-based fuels decreased by 26 PJ (petajoule ed.), Corresponding to 34 per cent. from 2018 to 2019, mirroring renewables overtaking coal in Germany. Nevertheless, net electricity generation was just under 30 TWh both years.

'It is worth noting that while fossil fuels are being phased out, Denmark maintains its annual net production of electricity. The green, so to speak, replaces the black. It once again underpins that green conversion, high security of supply and an affordable electricity price can go hand in hand, 'says Hanne Storm Edlefsen.

Danish power system is ready for a green future

Including trade in electricity with neighboring countries, 1 kWh in a Danish outlet generates 145 gr CO2 / kWh.

'There has been a very significant development in the Danish electricity system in recent years, where the electricity system can now be operated solely on the renewable energy. It is a remarkable development, also from an international perspective where low-carbon progress stalled in the UK in 2019, that one would not have thought possible for just a few years ago, 'he says.

More than expected have phased out coal

The electricity from the Danish sockets will be greener , predicts Energinet's environmental report , which expects CO2 intensity in the coming years. This is explained by an expectation of increased electrification of energy consumption, together with a continued expansion with wind and solar.

'Wind energy is the cornerstone of the green transition. With the commissioning of the Kriegers Flak offshore wind farm and several major onshore wind turbine projects within the next few years, we can well expect that only the wind's share of electricity consumption will exceed 50 per cent hopefully as early as 2021,' concludes Soren Klinge.

Renewable Energy Tax Incentive Extensions urged by US trade groups to offset COVID-19 supply chain delays, tax equity shortages, and financing risks, enabling direct pay, PTC and ITC qualification, and standalone energy storage credits.

Key Points

Policy measures that extend and monetize clean energy credits to counter COVID-19 disruptions and financing shortfalls.

✅ Extend start construction and safe harbor deadlines

✅ Enable direct pay to offset reduced tax equity

✅ Add a standalone energy storage credit

Renewable energy and other trade bodies in the US are calling on Capitol Hill to extend provision of tax incentives to help the sector “surmount the impacts” of the COVID-19 crisis facing clean energy.

In a signed joint letter, the American Council on Renewable Energy (ACORE), American Wind Energy Association (AWEA), Energy Storage Association (ESA), National Hydropower Association (NHA), Renewable Energy Buyers Alliance (REBA), and the Solar Energy Industries Association (SEIA) stated: “With over $50bn in annual investment over each of the past five years, the clean energy sector is one of the nation’s most important economic drivers. But that growth is placed at risk by a range of COVID-19 related impacts”.

These include “supply chain disruptions that have the potential to delay utility solar construction timetables and undermine the ability of wind, solar and hydropower developers to qualify for time-sensitive tax credits, and a sudden reduction in the availability of tax equity, which is crucial to monetising tax credits and financing clean energy projects of all types.”
The letter goes onto state: “Like all sectors of our economy the renewable and clean grid industry – including developers, manufacturers, construction workers, electric utilities, investors and major corporate consumers of renewable power – needs stability.

“The current uncertainty about the ability to qualify for and monetise tax incentives will have real and substantial negative impacts to the entire economy.

On behalf of the thousands of companies that participate in America’s renewable and clean energy economy, the coalition of organisations is requesting the US Government, echoing Senate calls to support clean energy, take three “critical” steps to address pandemic-related disruptions.

The first is an extension of start construction and safe harbour deadlines to ensure that renewable projects can qualify for renewable tax credits amid the Solar ITC extension debate and despite delays associated with supply chain disruptions.

The second is the implementation of provisions that will allow renewable tax credits to be available for direct pay to facilitate their monetisation, supporting U.S. solar and wind growth in the face of reduced availability of tax equity.

Thirdly, the signatories have requested the enactment of a direct pay tax credit for standalone energy storage to foster renewable growth as the industry sets sights on market majority and help secure a more resilient grid.
