Main US utility firm Duke Energy’s carbon discount plan for its North and South Carolina companies contains proposals for a “vital development” in energy storage deployments.

The corporate mentioned in its Carolinas Carbon Plan, filed yesterday with the regulatory North Carolina Utilities Fee (NCUC) that it needs to place between 3,700MW and 5,900MW of energy storage in its service space by 2035.

This might assist the expansion of renewables, together with a tripling of {solar} PV installations from present ranges and the addition of wind energy sources to diversify its renewable energy portfolio, the corporate mentioned.

By 2035, this could equate to between about 7,600MW and 11,900MW of recent {solar} PV, on high of 5,000MW of {solar} PV that will probably be on-line within the utility’s Carolinas service space by the top of 2022 and an extra 1,900MW of {solar} deliberate or already in growth.

Alongside these developments, Duke additionally needs to be allowed to take what it mentioned can be “preliminary steps” to creating zero-emitting load-following sources (ZELFRs), clear or carbon-free that may be equipped on-demand. This might embrace superior nuclear energy stations, carbon seize, storage and utilisation and different applied sciences like next-generation geothermal or hydrogen storage.

These ZELFRs and wind energy, that are newer to the energy combine within the Carolinas, will begin to come to the fore in direction of the top of this decade, the utility mentioned.

An govt order issued by North Carolina’s governor Roy Cooper in January this 12 months set coverage targets for emissions reductions of fifty% in comparison with 2005 ranges by 2030 and the achievement of web zero emissions standing by 2050 on the newest.

Duke Energy claimed that its Carolinas Carbon Plan is consistent with these goals, and that all the choices its proposal units out would meet different metrics set by the chief order, together with these on choosing the bottom value choices and sustaining electric system and provide reliability.

The utility mentioned it’s taking an “all the above” method, via the combo of applied sciences it proposes to make use of, from pure gasoline and small modular nuclear reactors to {solar} PV, wind energy and energy storage.

It could additionally take rapid motion to implement energy effectivity and demand-side administration in addition to upgrades to the grid to allow it to host larger shares of renewables.

As soon as carried out, the plan can be reviewed each two years.


By 2030, the utility is proposing:

  • 3,400MW discount in peak demand via energy effectivity and demand-side administration
  • 3,100MW of recent {solar} PV, together with 600MW paired with energy storage
  • 2,000MW of recent pure gasoline models that are ‘hydrogen succesful’
  • 1,000MW of standalone battery energy storage
  • 600MW of onshore wind
  • Early growth work to allow 800MW of offshore wind
  • Early growth work to allow 570MW of small modular nuclear
  • Early growth work to allow 1,700MW of pumped hydro energy storage (PHES)

The plan may allow a 70% CO2 discount by 2030 in addition to carbon neutrality by 2050, Duke Energy claimed, whereas the corporate can also be dedicated to closing its North and South Carolina coal crops by 2035.

Duke Energy mentioned the truth that it has a dual-state system in operation between each Carolinas helps it to maintain prices low and preserve reliability, citing buyer charges which might be beneath nationwide averages. The plan, to even be filed with South Carolina’s Public Service Fee, would necessitate a rise buyer charges between 1.9% and a pair of.7% every year to 2035.

4 separate portfolio choices have been included in it, every with a barely totally different mixture of sources. Whereas one choice may attain 70% CO2 discount by 2030, the others would take barely longer, till 2032 or 2034, to realize that, though all 4 would lead to carbon neutrality by 2050.

Duke Energy has round 7.4 million prospects for its energy companies in six US states, in addition to round 1.5 million retail pure gasoline prospects in 4 states. In March the corporate introduced the completion of three lithium-ion battery projects in Florida, totalling 34MW/58MWh. Duke additionally joined up with expertise supplier Honeywell to roll out microgrids for cities across the US a couple of weeks in the past.

The utility’s planning processes got here in for criticism in 2021, when its 2020 Built-in Useful resource Plan (IRP) was described as flawed by energy consulting agency E3. E3 mentioned that the IRP didn’t successfully enable for the variety advantages of {solar} and storage to be captured, our sister web site PV Tech reported on the time.

Duke’s capability enlargement methodology thought-about {solar} and storage independently, at totally different steps of the method, which E3 argued meant the synergistic benefits that exist between the two were ignored.

Because the world strikes in the direction of electrifying the transport system with the utilisation of electrical vehicles, scooters, busses, trains and many others. we want to ensure we bear in mind the inherent risks of lithium-ion batteries.

It isn’t unusual for lithium-ion batteries to catch hearth whereas charging whether or not they’re in telephones, computer systems, work instruments, home batteries or electric autos. There are various situations of homes and companies being burnt attributable to these fires.

One of many points with lithium-ion battery fires is the temperatures the fireplace will rapidly get to (extra of 1000oC) and the pace with which the fireplace will unfold to something adjoining it. The most important problem is that fireside brigades are unable to simply extinguish a lithium-ion battery hearth. All they will actually do is defend surrounding property to stop the fireplace spreading.

6 buses destroyed in UK 230522 – 2 have been electric – 2 electric and 4 non-electric busses have been destroyed. Believed to have began in a single lithium-ion battery exploding whereas being charged. Fireplace rapidly destroyed that bus and unfold to adjoining busses and busses have been alight inside minutes when firemen arrived. Plumes of poisonous smoke might be seen 18 kilometres away. Onlookers likened the ‘unbelievable noise’ to that of an explosion. There have been no reported accidents.

2 buses destroyed in France 290422 – 2 have been electric On 2 separate events stationary busses caught hearth on the streets in Paris. Smoke was seen coming from the highest of the bus and rapidly engulfed the entire bus. Passengers have been evacuated and no-one was injured in both incident. Burning particles was seen on digicam being ejected from the roof, falling onto the sidewalk and the street like a rain of fireplace.

25 buses destroyed in Germany 300921 – 2 have been electric –  Each electric and non-electric busses have been destroyed. Believed to have began in a single lithium-ion battery whereas being charged and rapidly destroyed that bus and unfold to adjoining non electric busses. Six workers acquired medical consideration through the hearth.

4 out of 5 electric buses destroyed in China 180521 –  A battery malfunction precipitated an electrical bus to catch hearth in southern. In seconds, the flames engulfed a number of equivalent busses parked adjoining to the automobile.

Lithium-ion batteries are infamous for being troublesome to place out as soon as they’ve caught hearth. Lithium-ion batteries typically reignite as soon as they’ve caught hearth and the fireplace has been put out. This may occur hours and even days after the fireplace is believed to have been extinguished. It’s much more troublesome for hearth fighters in that they will’t use water or another suppression strategies to extinguish a lithium-ion battery hearth as that might solely make the batteries explode and exacerbate the issues. You simply have to attend for the fireplace to burn itself out and defend surrounding infrastructure whereas taking thermal temperature readings each two hours.

Though electric autos with lithium-ion batteries, like most petrol or diesel autos are inherently secure the push for cheaper batteries with little regulation on battery security results in security typically being compromised. That is resulting in an rising variety of lithium-ion battery fires in varied purposes. Fortunately, so far, most lithium-ion battery fires have led to lack of autos or homes however not human lives, though there have been some human deaths.

When putting in energy storage batteries, each domestically and in enterprise, or neighborhood or grid help bigger installations, extra individuals are turning into conscious or the dangers related to batteries which have a risk of going into thermal runaway.

Increasingly more individuals are recognising that one of many main points with energy storage batteries are the risks with fires and explosions notably related to thermal runaway (self-sustaining fires). This has turn into notably related as individuals are contemplating putting in the numerous lithium-ion battery applied sciences of their homes or companies and have gotten conscious of the opportunity of the risks related to this.

Philippines’ SMC Global Power past halfway mark in 1,000MWh battery storage rollout – report



Fluence’s first Philippines project in 470MW battery storage portfolio enters commercial operation 

The primary 500MWh of a battery storage portfolio for SMC World Energy, a completely owned subsidiary of main Philippines holding firm San Miguel Company, has been put in.

In response to a report by newspaper Manilla Customary, the corporate introduced it had reached the midway level in its rollout of 1,000MW/1,000MWh of battery energy storage programs yesterday (30 June 2022).

The system will present grid balancing providers to electrical energy networks on islands within the Southeast Asian nation, similar to frequency response, reserve energy and voltage regulation.

The Customary quoted San Miguel Company president Ramon Ang as having stated put in capability will attain 700MWh by the top of 2022 and all 31 amenities within the pipeline will likely be accomplished “inside 12 months”.

Energy-Storage.information reached out to San Miguel Company – one of many Philippines’ largest privately-owned entities –  to investigate in regards to the information and for additional particulars however is but to obtain a reply.

What is understood nevertheless is that set up of about 80MW/80MWh of the primary battery energy storage programs (BESS) within the portfolio was accomplished and introduced final June.

A 20MW/20MWh system delivered by international system integrator Fluence was then entered into commercial operations at the beginning of this year. Fluence equipped, put in and commissioned the system on a turnkey engineering, procurement and development (EPC) contract foundation.

Fluence had revealed it was contracted to ship 470MW/470MWh of the preliminary buildout, which SMC stated it was investing round US$1 billion into, whereas different firms identified to be engaged on tasks embody Wärtsilä and ABB.

SMC: Complete progress at 61% as of finish of Could

SMC has progressed challenge improvement rapidly. Having been the primary firm to deploy a large-scale BESS of 10MW/10MWh within the nation, on the website of a coal plant it owns, it stated in April 2021 that it aimed to construct tasks within the new portfolio “concurrently”.

In a prospectus filed with the Philippines Securities and Trade Fee (SEC) on the finish of Could this yr, SMC World Energy famous that its diversified energy portfolio stood at 4,734MW, comprising property together with pure fuel, coal, renewable energy and battery energy storage programs.   

This is the same as 19% of capability on the Nationwide Grid, 26% of capability on the grid of the island of Luzon and seven% of capability on Mindanao’s grid.

SMC famous that the 20MW Masinloc BESS challenge which Fluence accomplished entered right into a five-year ancillary providers settlement with Nationwide Grid Company from January. It’s anticipated that related contracts will likely be entered into over the approaching months for the subsequent tasks.

As of the top of April, almost all the tools required for the 1,000MW portfolio had been delivered to challenge websites, together with 860MWh of battery modules and 690MWh of inverters. Whereas the quantity of energy capability put in has reached 500MWh, precise challenge completion for the portfolio was at about 61% by that point, the corporate stated in its SEC-filed prospectus.

SMC stated 4 websites totalling 80MWh had been absolutely accomplished, 150MWh was present process testing and commissioning and eight extra websites totalling 260MWh could be coming into testing and commissioning throughout Could.

One other fascinating level disclosed to the SEC is that SMC entered right into a Memorandum of Understanding with battery producer Samsung SDI in January 2020. This gave the ability firm most popular buyer standing, and tied Samsung SDI into efficiency ensures, aggressive pricing, warranties and different deal phrases.

SMC World Energy listed gaining market share for ancillary providers “and renewable energy initiatives” by means of battery energy storage programs amongst its principal enterprise methods. It’s actively searching for alternatives to develop battery programs for purposes that embody peak shaving, microgrids, energy high quality administration, black begin of energy crops and grids, energy aggregation, reactive energy help and different ancillary providers.

That is together with renewable energy integration purposes, with the corporate constructing lots of of megawatts of {solar} PV within the Philippines, which goes by means of an ongoing interval of rising demand for electrical energy amid calls to scale back its reliance on coal-fired technology.

Different energy technology firms within the nation are additionally developing standalone battery storage, whereas the Philippines first solar-plus-storage hybrid plant got here on-line this yr. A lately proposed giga-hybrid challenge might pair between 2,500MW and 3,500MW of solar PV with between 4,000MWh and 4,500MWh of BESS, Prime Infrastructure Holdings, the corporate behind it, stated.

Final month, Energy-Storage.information reported that the Philippines Division of Energy had issued builders of 529MW /829MWh battery tasks with clearance to undertake grid impact studies for their proposals.
