It seems like an idea any environmentalist would embrace: Build one of the world's largest solar power operations in the Southern California desert and surround it with plants that run on wind and underground heat.
Yet San Diego Gas & Electric Co. and its potential partners face fierce opposition because the plan also calls for a 150-mile, high-voltage transmission line that would cut through pristine parkland to reach the nation's eighth-largest city.
The showdown over how to get renewable energy to consumers will likely play out elsewhere around the country as well, as state regulators require electric utilities to rely less on coal and natural gas to fire their plants — the biggest source of carbon dioxide emissions in the U.S.
Providers of renewable power covet cheap land and abundant sunshine and wind in places like west Texas, Montana, Wyoming and California's Mojave Desert and Imperial Valley. But utility executives say no one will build plants without power lines to connect those remote spots to big cities.
"This is a classic chicken and the egg," said Mike Niggli, chief operating officer of Sempra Energy's utilities business, which includes SDG&E. "No one can develop a project if they can't send (the electricity) anywhere. You need transmission."
SDG&E's $1.5-billion power line would cut 23 miles through the middle of Anza-Borrego Desert State Park, a spot known for its hiking trails, wildflowers, palm groves, cacti and spectacular mountain views.
"This transmission line will cross through some of the most scenic areas of San Diego," said David Hogan of the Center for Biological Diversity. "It would just ruin it with giant, metal industrial power lines."
Environmentalists are pushing for renewable power to be generated closer to heavily populated areas, rather than brought in from distant sites. They point to Southern California Edison's ambitious plan for solar panels on Los Angeles-area rooftops as an example of a better approach.
Utilities say the roof panels will help but won't produce nearly enough power to satisfy state requirements.
The California Public Utilities Commission is scheduled to vote as soon as August on SDG&E's proposed Sunrise Powerlink, which would carry enough power for about 750,000 homes — or more than half of the utility's customers.
Regulators in 29 states and the District of Columbia are forcing utilities to boost the use of renewable energy to run electric plants.
California has been among the most aggressive, with the state's three investor-owned utilities required to get 20 percent of power from renewables by the end of 2010.
Gov. Arnold Schwarzenegger wants to reach 33 percent by 2020.
SDG&E, with 1.4 million customers, is California's laggard, getting just 6 percent of its power from renewables. PG&E Corp.'s Pacific Gas and Electric, with 5.1 million customers, gets 12 percent. Edison International's Southern California Edison, with 4.8 million customers, gets 16 percent.
Nationwide, utilities get only 2 percent of electricity from renewables, said Jone-Linn Wang, managing director of the global power group at Cambridge Energy Research Associates.
Edison hopes to draw more on solar and wind power by building a transmission line from the Mojave Desert to the Los Angeles area.
"It's a trade-off," said Stuart Hemphill, Edison's vice president for renewable and alternative power. "Clean energy perhaps requires building infrastructure in potentially sensitive areas. There's no way around it."
SDG&E's proposed route through Anza-Borrego, California's largest state park, ranked second worst among seven possible routes studied by state and federal regulators for environmental damage.
The plan calls for 141 towers through the park at an average height of 130 feet. The entire route would include 554 towers from the wind-swept desert of the Imperial Valley to a site near the Pacific Ocean in San Diego.
SDG&E would build the power line but buy the juice from a host of generating companies whose proposed plants harness energy from the sun, wind and underground heat.
The most ambitious generation project relies on a commercially untested technology for a gigantic solar plant.
Stirling Energy Systems Inc., a Phoenix startup, wants to build 12,000 solar dishes, each four stories tall, near El Centro, about 100 miles east of San Diego.
Stirling says a $100 million investment from NTR PLC, an Irish energy holding company, will pay for permits and design work, with construction to begin by the end of 2009. Bruce Osborn, Stirling's chief operating officer, estimates the plant itself will cost about $400 million.
That plant would initially feed into an existing power line and provide enough electricity for more than 200,000 homes, Osborn said. Stirling, however, would need more transmission capacity to pursue plans to triple the size of the plant, he said.
The technology relies on mirrored dishes collecting sunlight to heat gas and drive the cylinders of an engine. It has been tested on six solar dishes in New Mexico but now would move to mass production — drawing plenty of skepticism from environmentalists.
"It's what we call new product introduction," responds Osborn, a former project manager at Ford Motor Co. "Everyone who builds a widget does the same thing. This is a big widget."
Even without Stirling, SDG&E has other, traditional renewable power generators knocking on its door with deals to provide power — far more than the utility could accommodate, Niggli said.
Environmentalists have dueled for years with SDG&E's parent company, Sempra Energy, over operations just south of the border in Mexico that help supply power to the western U.S.
Critics claim Sempra built the plants in Mexico to skirt more rigorous environmental reviews in the U.S. They suggest SDG&E's proposed power line, which would start near the Mexican border, is part of a disguised effort to get electricity into the U.S. from Mexico, where Sempra has an electricity plant and the first liquefied natural gas terminal on the West Coast.
SDG&E dismisses those claims as a conspiracy theory.
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
Canada Three-Layer Mask Recommendation advises non-medical masks with a polypropylene filter layer and tightly woven cotton, aligned with WHO guidance, to curb COVID-19 aerosols indoors through better fit, coverage, and public health compliance.
Key Points
PHAC advises three-layer non-medical masks with a polypropylene filter to improve indoor COVID-19 protection.
✅ Two fabric layers plus a non-woven polypropylene filter
✅ Ensure snug fit: cover nose, mouth, chin without gaps
✅ Aligns with WHO guidance for aerosols and droplets
The Public Health Agency of Canada is now recommending Canadians choose three-layer non-medical masks with a filter layer to prevent the spread of COVID-19, even as an IEA report projects higher electricity needs for net-zero, as they prepare to spend more time indoors over the winter.
Chief Public Health Officer Dr. Theresa Tam made the recommendation during her bi-weekly pandemic briefing in Ottawa Tuesday, as officials also track electricity grid security amid critical infrastructure concerns.
"To improve the level of protection that can be provided by non-medical masks or face coverings, we are recommending that you consider a three-layer nonmedical mask," she said.
Trust MedProtect For All Your Mask Protection

According to recently updated guidelines, two layers of the mask should be made of a tightly woven fabric, such as cotton or linen, and the middle layer should be a filter-type fabric, such as non-woven polypropylene fabric, as Canada explores post-COVID manufacturing capacity for PPE.
"We're not necessarily saying just throw out everything that you have," Tam told reporters, suggesting adding a filter can help with protection.
The Public Health website now includes instructions for making three-layer masks, while national goals like Canada's 2050 net-zero target continue to shape recovery efforts.
The World Health Organization has recommended three layers for non-medical masks since June, and experts note that cleaning up Canada's electricity is critical to broader climate resilience. When pressed about the sudden change for Canada, Tam said the research has evolved.
"This is an additional recommendation just to add another layer of protection. The science of masks has really accelerated during this particular pandemic. So we're just learning again as we go," she said.
"I do think that because it's winter, because we're all going inside, we're learning more about droplets and aerosols, and how indoor comfort systems from heating to air conditioning costs can influence behaviors."
She also urged Canadians to wear well-fitted masks that cover the nose, mouth and chin without gaping, as the federal government advances emissions and EV sales regulations alongside public health guidance.
AIDAsol shore power Rostock-Warnem fcnde delivers cold ironing for cruise ships, up to 20 MVA at berths P7 and P8, cutting port emissions during berthing and advancing AIDA's green cruising strategy across European ports.
Key Points
Rostock-Warnem fcnde shore power supplies two cruise ships up to 20 MVA, enabling cold ironing and cutting emissions.
✅ Up to 20 MVA; powers two cruise ships at berths P7 and P8
✅ Enables cold ironing for AIDA fleet to reduce berth emissions
✅ Part of AIDA green cruising with fuel cells and batteries
In a ceremony held in Rostock-Warnemünde yesterday during Germany’s 12th National Maritime Conference, the 2,174-passenger cruise ship AIDAsol inaugurated Europe’s largest shore power plants for ships.
The power plant has been established under a joint agreement between AIDA Cruises, a unit of Carnival Corporation & plc (NYSE/LSE: CCL; NYSE: CUK), the state government of Mecklenburg-Western Pomerania, the city of Rostock and the Port of Rostock.
“With our green cruising strategy, we have been investing in a sustainable cruise market for many years,” said AIDA Cruises President Felix Eichhorn. “The shore power plant in Rostock-Warnemünde is another important step — after the facility in Hamburg — on our way to an emission-neutral cruise that we want to achieve with our fleet. I would like to thank the state government of Mecklenburg-Western Pomerania and all partners involved for the good and trusting cooperation. Together, we are sending out an important signal, not just in Germany, but throughout Europe.”
CAN POWER TWO CRUISE SHIPS AT A TIME The shore power plant, which was completed in summer 2020, is currently the largest in Europe and aligns with port electrification efforts such as the all-electric berth at London Gateway in the UK. With an output of up to 20 megavolt amperes (MVA), two cruise ships can be supplied with electricity at the same time at berths P7 and P8 in Warnemünde.
In regular passenger operation AIDAsol needs up to 4.5 megawatts per hour (MWh) of electricity.
The use of shore power to supply ships with energy is a decisive step in AIDA Cruises’ plans to reduce local emissions to zero during berthing, complementing recent progress with electric ships on the B.C. coast, as a cruise ship typically stays in port around 40% of its operating time.
As early as 2004, when the order for the construction of AIDAdiva was placed, and for all other ships put into service in subsequent years, the company has considered the use of shore power as an option for environmentally friendly ship operation.
Since 2017, AIDA Cruises has been using Europe’s first shore power plant in Hamburg-Altona, where AIDAsol is in regular operation, while operators like BC Ferries add hybrid ferries to expand low-emission service in Canada. Currently, 10 ships in the AIDA fleet can either use shore power where available or are technically prepared for it.
The aim is to convert all ships built from 2000 onwards, supporting future solutions like offshore charging with wind power.
With AIDA Cruises starting a cruise season from Kiel, Germany, on May 22, AIDAsol will also be the first cruise ship to complete the final tests on a newly built shore power plant there, as innovations such as Berlin’s electric flying ferry highlight the broader shift toward electrified waterways. Construction of that plant is the result of a joint initiative by the state government of Schleswig-Holstein, the city and the port of Kiel and AIDA Cruises. AIDAsol is scheduled to arrive in Kiel on the afternoon of May 13.
As part of its green cruising strategy, AIDA Cruises has been investing in a sustainable cruise operation for many years, paralleling urban shifts toward zero-emission bus fleets in Berlin. Other steps on the path to the zero emission ship of the future are already in preparation. This year, AIDAnova will receive the first fuel cell to be used on an ocean-going cruise ship. In 2022, the largest battery storage system to date in cruise shipping will go into operation on board an AIDA ship, similar to advances in battery-electric ferries in the U.S. In addition, the company is already addressing the question of how renewable fuels can be used on board cruise ships in the future.
Middle Tennessee Power Outages disrupt 100,000+ customers as severe thunderstorms, straight-line winds, downed trees, and debris challenge Nashville crews, slow restoration amid COVID-19, and threaten more hail, flash flooding, and damaging gusts.
Key Points
Blackouts across Nashville after severe storms and winds, leaving customers without power and facing restoration delays.
✅ Straight-line winds 60-80 mph toppled trees and power lines
✅ 130,000+ customers impacted; some outages may last 1-2 weeks
✅ Restoration slowed by debris, COVID-19 protocols, and new storms
Some middle Tennessee residents could be without electricity for up to two weeks after strong thunderstorms swept through the area Sunday, knocking out power for more than 100,000 customers, a scale comparable to Los Angeles outages after a station fire.
"Straight line winds as high as 60-80 miles per hour knocked down trees, power lines and power polls, interrupting power to 130,000 of our 400,000+ customers," Nashville Electric said in a statement Monday. The utility said the outage was one of the largest on record, though Carolina power outages recently left a quarter-million without power as well.
"Restoration times will depend on individual circumstances. In some cases, power could be out for a week or two" as challenges related to coronavirus and the need for utilities adapt to climate change complicated crews' responses and more storms were expected, the statement said. "This is unfortunate timing on the heels of a tornado and as we deal with battling COVID-19."
Metropolitan Nashville and Davidson County Mayor John Cooper also noted that the power outages were especially inconvenient, a challenge similar to Hong Kong families without power during Typhoon Mangkhut, as people were largely staying home to slow the spread of coronavirus. He also pointed out that the storms came on the two month anniversary of the Nashville tornado that left at least two dozen people dead.
"Crews are working diligently to restore power and clear any debris in neighborhoods," Cooper said.
He said that no fatalities were reported in the county but sent condolences to Spring Hill, whose police department reported that firefighter Mitchell Earwood died during the storm due to "a tragic weather-related incident" while at his home and off duty. He had served with the fire department for 10 years.
The Metro Nashville Department of Public Works said it received reports of more than 80 downed trees in Davidson County.
Officials also warn that copper theft can be deadly when electrical infrastructure is damaged after storms.
The National Weather Service Nashville said a 72 mph wind gust was measured at Nashville International Airport — the fifth fastest on record.
The weather service warned that strong storms with winds of up to 75 mph, large hail, record-long lightning bolt potential seen in the U.S., and isolated flash flooding could hit middle Tennessee again Monday afternoon and night.
"Treat Severe Thunderstorm Warnings the same way you would Tornado Warnings and review storm safety tips before you JUST TAKE SHELTER," the NWS instructs. "70 mph is 70 mph whether it's spinning around in a circle or blowing in a straight line."
Siwash Creek Hydroelectric Project faces downsizing under a BC Hydro power purchase agreement, with run-of-river generation, high grid interconnection costs, First Nations partnership, and surplus electricity from Site C reshaping clean energy procurement.
Key Points
A downsized run-of-river plant in BC, co-owned by Kanaka Bar and Green Valley, selling power via a BC Hydro PPA.
✅ Approved at 500 kW under a BC Hydro clean-energy program
✅ Grid interconnection initially quoted at $2.1M
✅ Joint venture: Kanaka Bar and Green Valley Power
A small run-of-river hydroelectric project recently selected by B.C. Hydro for a power purchase agreement may no longer be financially viable.
The Siwash Creek project was originally conceived as a two-megawatt power plant by the original proponent Chad Peterson, who holds a 50-per-cent stake through Green Valley Power, with the Kanaka Bar Indian Band holding the other half.
The partners were asked by B.C. Hydro to trim the capacity back to one megawatt, but by the time the Crown corporation announced its approval, it agreed to only half that — 500 kilowatts — under its Standing Order clean-energy program.
“Hydro wanted to charge us $2.1 million to connect to the grid, but then they said they could reduce it if we took a little trim on the project,” said Kanaka Bar Chief Patrick Michell.
The revenue stream for the band and Green Valley Power has been halved to about $250,000 a year. The original cost of running the $3.7-million plant, including financing, was projected to be $273,000 a year, according to the Kanaka Bar economic development plan.
“By our initial forecast, we will have to subsidize the loan for 20 years,” said Michell. “It doesn’t make any sense.”
The Kanaka Band has already invested $450,000 in feasibility, hydrology and engineering studies, with a similar investment from Green Valley.
B.C. Hydro announced it would pursue five purchase agreements last March with five First Nations projects — including Siwash Creek — including hydro, solar and wind energy projects, as two new generating stations were being commissioned at the time. A purchase agreement allows proponents to sell electricity to B.C. Hydro at a set price.
However, at least ten other “shovel-ready” clean energy projects may be doomed while B.C. Hydro completes a review of its own operations and its place in the energy sector, where legal outcomes like the Squamish power project ruling add uncertainty, including B.C.’s future power needs.
With the 1,100-megawatt Site C Dam planned for completion in 2024, and LNG demand cited to justify it, B.C. Hydro now projects it will have a surplus of electricity until the early 2030s.
Even if British Columbians put 300,000 electric vehicles on the road over the next 12 years, amid BC Hydro’s first call for power, they will require only 300 megawatts of new capacity, the company said.
A long-term surplus could effectively halt all small-scale clean energy development, according to Clean Energy B.C., even as Hydro One’s U.S. coal plant remains online in the region.
“(B.C. Hydro) dropped their offer down to 500 kilowatts right around the time they announced their review,” said Michell. “So we filled out the paperwork at 500 kilowatts and (B.C. Hydro) got to make its announcement of five projects.”
In the new few weeks, Kanaka and Green Valley will discuss whether they can move forward with a new financial model or shelve the project, he said.
B.C. Hydro declined to comment on the rationale for downsizing Siwash Creek’s power purchase agreement.
The Kanaka Bar Band successfully operates a 49.9-megawatt run-of-river plant on Kwoiek Creek with partners Innergex Renewable Energy.
Grid Modernization drives utilities to integrate DER, AMI, and battery storage while balancing reliability, safety, and affordability; regulators pursue cost-benefit analyses, new rate design, and policy actions to guide investment and protect customer-owned resources.
Key Points
Upgrading the grid to manage DER with digital tools, while maintaining reliability, safety, and customer affordability.
✅ AMI and storage deployments enable DER visibility and control
✅ Rate design reforms support customer-owned resources
Utilities’ pursuit of a modern grid, including the digital grid concept, to maintain the reliability and safety pillars of electricity delivery has raised a lot of questions about the third pillar — affordability.
Utilities are seeing rising penetrations of emerging technologies, highlighted in recent grid edge trends reports, like distributed solar, behind-the-meter battery storage, and electric vehicles. These new distributed energy resources (DER) do not eliminate utilities' need to keep distribution systems safe and reliable.
But the need for modern tools to manage DER imposes costs on utilities, prompting calls to invest in smarter infrastructure even as some regulators, lawmakers and policymakers are concerned those costs could drive up electricity rates.
The result is an increasing number of legislative and regulatory grid modernization actions aimed at identifying what is necessary to serve the coming power sector transformation and address climate change risks across the grid.
The rise of grid modernization
Grid modernization, which is supported by both conservatives and distributed energy resources advocates, got a lot of attention last year. According to the 2017 review of grid modernization policy by the North Carolina Clean Energy Technology Center (NCCETC), 288 grid modernization policy actions were proposed, pending or enacted in 39 states.
These numbers from NCCETC's first annual review of policy activity set a benchmark against which future years' activity can be measured.
The most common type of state actions, by far, were those that focused on the deployment of advanced metering infrastructure (AMI) and battery energy storage. Those are two of the 2017 trends identified in NCCETC’s 50 States of Grid Modernization report. But deployment of those technologies, while foundational to an updated grid, only begins to prepare distribution systems for the coming power sector transformation.
Bigger advances, including the newest energy system management tools, are being held back by 2017’s other policy actions requiring more deliberation and fact-finding, even as grid vulnerability report cards underscore the risks that modernization seeks to mitigate.
Utilities’ proposals to more fully prepare their grids to deliver 21st century technologies are being met with questions about completeness and cost.
Utilities are being asked to address these questions in comprehensive, public utility commission-led cost-benefit analyses and studies. This is also one of NCCETC’s top 2017 policy action trends for grid modernization. The outcome to date appears to be an increased, but still incomplete, understanding of what is needed to build a 21st century grid.
Among the top objectives of those driving the policy actions are resolving questions about private sector participation in grid modernizaton buildouts and developing new rate designs to protect and support customer-owned distributed energy resources. Actions on those topics are also on NCCETC’s list of 2017 policy trends.
Altogether, the trend list is dominated by actions that do not lead to completion of grid modernization but to more work on it.
