Scottish Renewable Grid Upgrades address outdated infrastructure, expanding transmission lines, pylons, and substations to move clean energy, meet rising electricity demand, and integrate onshore wind, offshore wind, and battery storage across Scotland.

Key Points

Planned transmission upgrades in Scotland to move clean power via new lines and substations for a low-carbon grid.

✅ Fivefold expansion of transmission lines by 2030

✅ Enables onshore and offshore wind integration

✅ New pylons, substations, and routes face local opposition

Renewable energy in Scotland is being held back by outdated grid infrastructure, industry leaders said, with projects stuck on hold underscoring their warning that new pylons and power lines are needed to "ensure our lights stay on".

Scottish Renewables said new infrastructure is required to transmit the electricity generated by green power sources and help develop "a clean energy future" informed by a broader green recovery agenda.

A new report from the organisation - which represents companies working across the renewables sector - makes the case for electricity infrastructure to be updated, aligning with global network priorities identified elsewhere.

But it comes as electricity firms looking to build new lines or pylons face protests, with groups such as the Strathpeffer and Contin Better Cable Route challenging power giant SSEN over the route chosen for a network of pylons that will run for about 100 miles from Spittal in Caithness to Beauly, near Inverness.

Scottish Renewables said it is "time to be upfront and honest" about the need for updated infrastructure.

It said previous work by the UK National Grid estimated "five times more transmission lines need to be built by 2030 than have been built in the past 30 years, at a cost of more than £50bn".

The Scottish Renewables report said: "Scotland is the UK's renewable energy powerhouse. Our winds, tides, rainfall and longer daylight hours already provide tens of thousands of jobs and billions of pounds of economic activity.

"But we're being held back from doing more by an electricity grid designed for fossil fuels almost a century ago, a challenge also seen in the Pacific Northwest today."

Investment in the UK transmission network has "remained flat, and even decreased since 2017", echoing stalled grid spending trends elsewhere, the report said.

It added: "We must build more power lines, pylons and substations to carry that cheap power to the people who need it - including to people in Scotland.

"Electricity demand is set to increase by 50% in the next decade and double by mid-century, so it's therefore wrong to say that Scottish households don't need more power lines, pylons and substations.

"We need them to ensure our lights stay on, as excess solar can strain networks in the same way consumers elsewhere in the UK need them.

"With abundant natural resources, Scotland's home-grown renewables can be at the heart of delivering the clean energy needed to end our reliance on imported, expensive fossil fuel.

"To do this, we need a national electricity grid capable of transmitting more electricity where and when it is needed, echoing New Zealand's electricity debate as well."

Nick Sharpe, director of communications and strategy at Scottish Renewables, said the current electricity network is "not fit for purpose".

He added: "Groups and individuals who object to the construction of power lines, pylons and substations largely do so because they do not like the way they look.

"By the end of this year, there will be just over 70 months left to achieve our targets of 11 gigawatts (GW) offshore and 12 GW onshore wind.

"To ensure we maximise the enormous socioeconomic benefits this will bring to local communities, we will need a grid fit for the 21st century."

Martha's Vineyard 100% Renewable Energy advances electrification across EVs, heat pumps, distributed solar, offshore wind, microgrids, and battery storage, cutting emissions, boosting efficiency, and strengthening grid resilience for storms and sea-level rise.

Key Points

It is an islandwide plan to electrify transport and buildings using wind, solar, storage, and a modern resilient grid.

✅ Electrify transport: EV adoption and SSA hybrid-electric ferries.

✅ Deploy heat pumps for efficient heating and cooling in buildings.

✅ Modernize the grid: distributed solar, batteries, microgrids, VPP.

Over the past year, it has become increasingly clear that climate change is accelerating. Here in coastal New England, annual temperatures and precipitation have risen more quickly than expected, tidal flooding is now commonplace, and storms have increased in frequency and intensity. The window for avoiding the worst consequences of a climate-changed planet is closing.

At their recent special town meeting, Oak Bluffs citizens voted to approve the 100 per cent renewable Martha’s Vineyard warrant article; now, all six towns have adopted the same goals for fossil fuel reduction and green electricity over the next two decades. Establishing these targets for the adoption of renewable energy, though, is only an initial step. Town and regional master plans for energy transformation are being developed, but this is a whole-community effort as well. Now is the time for action.

There is much to do to combat climate change, but our most important task is to transition our energy system from one heavily dependent on fossil fuels to one that is based on clean electricity. The good news is that this can be accomplished with currently available technology, and can be done in an economically efficient manner.

Electrification not only significantly lowers greenhouse gas emissions, but also is a powerful energy efficiency measure. So even though our detailed Island energy model indicates that eliminating all (or almost all) fossil fuel use will mean our electricity use will more than double, posing challenges for state power grids in some regions, our overall annual energy consumption will be significantly lower.

So what do we specifically need to do?

The primary targets for electrification are transportation (roughly 60 peer cent of current fossil fuel use on Martha’s Vineyard) and building heating and cooling (40 per cent).

Over the past two years, the increase in the number of electric vehicle models available across a wide range of price points has been remarkable — sedans, SUVs, crossovers, pickup trucks, even transit vans. When rebates and tax credits are considered, they are affordable. Range anxiety is being addressed both by increases in vehicle performance and the growing availability of charging locations (other than at home, which will be the predominant place for Islanders to refuel) and, over time, enable vehicle-to-grid support for our local system. An EV purchase should be something everyone should seriously consider when replacing a current fossil vehicle.

The elephant in the transportation sector room is the Steamship Authority. The SSA today uses roughly 10 per cent of the fossil fuel attributable to Martha’s Vineyard, largely but not totally in the ferries. The technology needed for fully electric short-haul vessels has been under development in Scandinavia for a number of years and fully electric ferries are in operation there. A conservative approach for the SSA would be to design new boats to be hybrid diesel-electric, retrofittable to plug-in hybrids to allow for shoreside charging infrastructure to be planned and deployed. Plug-in hybrid propulsion could result in a significant reduction in emissions — perhaps as much as 95 per cent, per the long-range plan for the Washington State ferries. While the SSA has contracted for an alternative fuel study for its next boat, given the long life of the vessels, an electrification master plan is needed soon.

For building heating and cooling, the answer for electrification is heat pumps, both for new construction and retrofits. These devices move heat from outside to inside (in the winter) or inside to outside (summer), and are increasingly integrated into connected home energy systems for smarter control. They are also remarkably efficient (at least three times more efficient than burning oil or propane), and today’s technology allows their operation even in sub-zero outside temperatures. Energy costs for electric heating via heat pumps on the Vineyard are significantly below either oil or propane, and up-front costs are comparable for new construction. For new construction and when replacing an existing system, heat pumps are the smart choice, and air conditioning for the increasingly hot summers comes with the package.

A frequent objection to electrification is that fossil-fueled generation emits greenhouse gases — thus a so-called green grid is required in order to meet our targets. The renewable energy fraction of our grid-supplied electricity is today about 30 per cent; by 2030, under current legislation that fraction will reach 54 per cent, and by 2040, 77 per cent. Proposed legislation will bring us even closer to our 2040 goals. The Vineyard Wind project will strongly contribute to the greening of our electricity supply, and our local solar generation (almost 10 per cent of our overall electricity use at this point) is non-negligible.

A final important facet of our energy system transformation is resilience. We are dependent today on our electricity supply, and this dependence will grow. As we navigate the challenges of climate change, with increasingly more frequent and more serious storms, 2021 electricity lessons underscore that resilience of electricity supply is of paramount importance. In many ways, today’s electricity distribution system is basically the same approach developed by Edison in the late 19th century. In partnership with our electric utility, we need to modernize the grid to achieve our resiliency goals.

While the full scope of this modernization effort is still being developed, the outline is clear. First, we need to increase the amount of energy generated on-Island — to perhaps 25 per cent of our total electricity use. This will be via distributed energy resources (in the form of distributed solar and battery installations as well as community solar projects) and the application of advanced grid control systems. For emergency critical needs, the concept of local microgrids that are detachable from the main grid when that grid suffers an outage are an approach that is technically sound and being deployed elsewhere. Grid coordination of distributed resources by the utility allows for handling of peak power demand; in the early 2030s this could result in what is known as a virtual power plant on the Island.

The adoption of the 100 renewable Martha’s Vineyard warrant articles is an important milestone for our community. While the global and national efforts in the climate crisis may sometimes seem fraught, we can take some considerable pride in what we have accomplished so far and will accomplish in coming years. As with many change efforts, the old catch-phrase applies: think globally, act locally.

PGE Residential Energy Storage Pilot aggregates 525 home batteries into a virtual power plant, enabling distributed energy resources, smart grid control, renewable energy optimization, demand response, and backup power across Portland General Electric's area.

Key Points

A PGE program aggregating 525 batteries into a utility-run virtual power plant for renewables support and backup power.

✅ Up to 4 MW aggregated capacity from 525 residential batteries

✅ Monthly credits: $40 ($20 with solar) for grid services

✅ Enhances smart grid, DERs, resilience, and outage backup

Portland General Electric Company is set to launch a pilot program that will incentivize installation and connection of 525 residential energy storage batteries that PGE will dispatch, contributing up to four megawatts of energy to PGE's grid. The distributed assets will create a virtual power plant made up of small units that can be operated individually or combined to serve the grid, adding flexibility that supports PGE's transition to a clean energy future. When the program launches this fall, incentives will be available to residential customers across PGE's service area. Rebates will be available to customers within three neighborhoods participating in PGE's Smart Grid Test Bed, and income-qualified customers participating in Energy Trust of Oregon's Solar Within Reach offer.

PGE will study the full benefits of energy storage that these distributed energy assets can provide the grid while also increasing resiliency for each participating customer. PGE will operate and test the benefits of using homes' batteries, each capable of storing 12 to 16 kWh of energy, to optimize the use of renewable energy and grid capabilities. In the event of a power outage, participating customers can rely on them as a backup power resource.

"Our vision for clean energy relies on a smart, integrated grid. One of the ways that we'll achieve that is through creative partnerships and diversified energy resources, including those behind-the-meter," said Larry Bekkedahl, vice president of Grid Architecture, Integration and Systems Operation. "This pilot project will allow PGE to integrate even more intermittent renewable energy and enhance grid capabilities while also giving participating customers peace of mind in the event of an outage."

Energy storage maximizes renewables and the grid, improves power quality

Energy storage, including long-duration energy storage solutions, is vital to help capture and store energy from renewable power sources, such as wind and solar, that are more variable. As a virtual power plant, the residential battery storage pilot will create a single resource that can help the grid balance energy production with energy demand, freeing up the generation resources that are typically held on standby, ready to kick in when the wind doesn't blow or the sun doesn't shine. As a clean energy option that takes the place of standby resources, the virtual power plant also gives customers access to reliable energy, even in the event of system outages.

The test program will also allow PGE to test new smart-grid control devices across its distribution system that will more effectively allow a two-way exchange between PGE and pilot participants. The new controls will more actively manage the way that electricity is distributed across PGE's system to incorporate energy that customers generate, such as through solar panels, while also meeting power demand that is less predictable, such as for charging electric vehicles, supporting EVs for grid stability strategies. The controls will allow PGE to more actively manage power distribution to improve power quality for all customers.

Select rebates and incentives will be available to participants, aligned with electric vehicle programs that encourage transportation electrification

When it launches in fall 2020, participation in the program will be available to residential customers, including:

* Those across PGE's service area who already have or are installing a qualifying battery. Participation will require an application, and in exchange for allowing PGE to operate their battery for grid services, similar to programs where EV owners selling power back for compensation, participating customers will receive a monthly bill credit of $40, or $20 if the battery is charged with solar power.

* Customers across PGE's service area who are participating in the Solar Within Reach offering from Energy Trust of Oregon. Participants will be eligible for a $5,000 instant rebate in addition to the monthly bill credits.

* Those living within the PGE Smart Grid Test Bed who purchase a battery will be eligible for an instant rebate, in addition to the monthly bill credit of $40 or $20, which will allow PGE to test the localized grid impact of having a large concentration of battery storage devices available on one substation and explore interfaces with vehicle-to-grid pilots in the region.

PGE is working with Energy Trust to cost-effectively procure the residential battery storage systems, as utilities invest in advanced storage solutions across the region, by leveraging the existing Solar incentive program infrastructure and trade ally contractor network. Customers who participate in the program will own their battery systems, and rebates will only be available for systems installed by an Energy Trust solar trade ally. The program may also accept customers with a qualifying battery that is was previously installed, following a process to ensure safe operation.

EPA Power Plant Emissions Rule proposes strict greenhouse gas limits for coal and gas units, leveraging carbon capture (CCS) under the Clean Air Act to cut CO2 and accelerate decarbonization of the U.S. grid.

Key Points

A proposed EPA rule setting CO2 limits for coal and gas plants, using CCS to cut power-sector greenhouse gases.

✅ Applies to existing and new coal and large gas units

✅ Targets near-zero CO2 by 2038 via CCS or retirement

✅ Cites grid, health, and climate benefits; faces legal challenges

The Biden administration has proposed new limits on greenhouse gas emissions from coal- and gas-fired power plants, its most ambitious effort yet to roll back planet-warming pollution from the nation’s second-largest contributor to climate change.

A rule announced by the Environmental Protection Agency could force power plants to capture smokestack emissions using a technology that has long been promised but is not used widely in the United States, and arrives amid changes stemming from the NEPA rewrite that affect project reviews.

“This administration is committed to meeting the urgency of the climate crisis and taking the necessary actions required,″ said EPA Administrator Michael Regan.

The plan would not only “improve air quality nationwide, but it will bring substantial health benefits to communities all across the country, especially our front-line communities ... that have unjustly borne the burden of pollution for decades,” Regan said in a speech at the University of Maryland.

President Joe Biden, whose climate agenda includes a clean electricity standard as a key pillar, called the plan “a major step forward in the climate crisis and protecting public health.”

If finalized, the proposed regulation would mark the first time the federal government has restricted carbon dioxide emissions from existing power plants, following a Trump-era replacement of Obama’s power plant overhaul, which generate about 25% of U.S. greenhouse gas pollution, second only to the transportation sector. The rule also would apply to future electric plants and would avoid up to 617 million metric tons of carbon dioxide through 2042, equivalent to annual emissions of 137 million passenger vehicles, the EPA said.

Almost all coal plants — along with large, frequently used gas-fired plants — would have to cut or capture nearly all their carbon dioxide emissions by 2038, the EPA said, a timeline that echoed concerns raised during proposed electricity pricing changes in the prior administration. Plants that cannot meet the new standards would be forced to retire.

The plan is likely to be challenged by industry groups and Republican-leaning states, much like litigation over the Affordable Clean Energy rule unfolded in recent years. They have accused the Democratic administration of overreach on environmental regulations and warn of a pending reliability crisis for the electric grid. The power plant rule is one of at least a half-dozen EPA rules limiting power plant emissions and wastewater treatment rules.

“It’s truly an onslaught” of government regulation “designed to shut down the coal fleet prematurely,″ said Rich Nolan, president and CEO of the National Mining Association.

Regan denied that the power plant rule was aimed at shutting down the coal sector, but acknowledged — even after the end to the 'war on coal' rhetoric — “We will see some coal retirements.”

Wind And Solar Energy Growth is reshaping the global power mix, accelerating grid decarbonization as coal declines; boosted by pandemic demand drops, renewables now supply near 10% of electricity, advancing climate targets toward net-zero trajectories.

Key Points

It is the rise in wind and solar's share of electricity, driving decarbonization and displacing coal globally.

✅ Share doubled in five years across 83% of global electricity

✅ Coal's share fell; renewables neared 10% in H1 2020

✅ Growth still insufficient for 1.5 C; needs ~13% coal cuts yearly

Wind and solar energy doubled its share of the global power mix over the last five years, with renewable power records underscoring the trend, moving the world closer to a path that would limit the worst effects of global warming.

The sources of renewable energy made up nearly 10% of power in most parts of the world in the first half of this year, according to analysis from U.K. environmental group Ember, while globally over 30% of electricity is renewable in broader assessments.

That decarbonization of the power grid was boosted this year as shutdowns to contain the coronavirus reduced demand overall, leaving renewables to pick up the slack.

Ember analyzed generation in 48 countries that represent 83% of global electricity. The data showed wind and solar power increased 14% in the first half of 2020 compared with the same period last year while global demand fell 3% because of the impact of the coronavirus.

At the same time that wind turbines and solar panels have proliferated, coal’s share of the mix has fallen around the world. In some, mainly western European countries, where renewables surpassed fossil fuels, coal has been all but eliminated from electricity generation.

China relied on the dirtiest fossil fuel for 68% of its power five years ago, and solar PV growth in China has accelerated since then. That share dipped to 62% this year and renewables made up 10% of all electricity generated.

Still, the growth of renewables may not be going fast enough for the world to hit its climate goals, even as the U.S. is projected to have one-fourth of electricity from renewables soon, and coal is still being burnt for power in many parts of the world.

Coal use needs to fall by about 79% by 2030 from last year’s levels - a fall of 13% every year throughout the decade to come, and in the U.S. renewable electricity surpassed coal in 2022, Ember said.

New installations of wind farms are set to hold more or less steady in the next five years, according to data from BloombergNEF on deployment trends. That will make it difficult to realize a sustained pace of doubling renewable power every five years.

“If your expectations are that we need to be on target for 1.5 degrees, clearly we’re not going fast enough,” said Dave Jones, an analyst at Ember. “We’re not on a trajectory where we’re reducing coal emissions fast enough.”

Manitoba Hydro unpaid leave plan offers unpaid days off to curb workforce costs amid COVID-19, avoiding temporary layoffs and pay cuts, targeting $5.7M savings through executive, manager, and engineer participation, with union options under discussion.

Key Points

A cost-saving measure offering unpaid days off to avert layoffs and pay cuts, targeting $5.7M savings amid COVID-19.

✅ 3 unpaid days for executives, managers, engineers

✅ Targets $5.7M total; $1.4M from non-union staff

✅ Avoids about 240 layoffs over a four-month period

The Manitoba government's Crown energy utility is offering workers unpaid days off as an alternative to temporary layoffs or pay cuts, even as residential electricity use rises due to more working from home.

In an email to employees, Manitoba Hydro president Jay Grewal says executives, managers, and engineers will take three unpaid days off before the fiscal year ends next March.

She says similar options are being discussed with other employee groups, which are represented by unions, as the Saskatchewan COVID-19 crisis reshaped workforces across the Prairies.

The provincial government ordered Manitoba Hydro to reduce workforce costs during the COVID-19 pandemic, as some power operators considered on-site staffing plans, and at one point the utility said it was looking at 600 to 700 temporary layoffs.

The organization said it’s looking for targeted savings of $5.7 million, down from $11 million previously estimated, while peers like BC Hydro’s Site C began reporting COVID-19 updates.

A spokesperson for Manitoba Hydro said non-unionized staff taking three days of unpaid leave will save $1.4 million of the $5.7 million savings.

“Three days of unpaid leave for every employee would eliminate layoffs entirely,” the spokesperson said in an email. “For comparison, approximately 240 layoffs would have to occur over a four-month period, while measures like Alberta's worker transition fund aim to support displaced workers, to achieve savings of $4.3 million.”

Grewal says the unpaid days off were a preferred option among the executives, managers, and engineers in an industry that recently saw a Hydro One worker injury case.

She says unions representing the other workers have been asked to respond by next Wednesday.
