The platform, HOMER Entrance, gives battery dispatching modelling and technical and financial evaluation to assist mission builders maximise the income of their energy storage mission. It may present modelling for standalone storage in addition to these co-located with wind or {solar} PV.

“By offering correct, detailed outcomes for various system configurations, HOMER Entrance permits builders and financiers to judge the system’s efficiency and make crucial mission selections with confidence,” stated Colin Tareila, engineering supervisor of Renewables in UL’s Asset and Sustainability Efficiency group.

The brand new platform is an add-on to the present HOMER software program platform, which UL acquired in late 2019, when HOMER was best known for its microgrid software.

Customers can check and analyse the mission dimension, structure and expertise and optimise battery augmentation methods for taking part in energy and capability markets and assembly off-take settlement necessities.

Renewable mission builders at the moment are dealing with extra competitors and a rising demand for the availability of fresh, dependable energy, UL stated, and including batteries to tasks would permit them to extend revenues and system reliability. The software program incorporates modelling of varied worth streams associated to particular grid markets like California Unbiased System Operator (CAISO) and Electric Reliability Council of Texas (ERCOT).

In abstract, HOMER Entrance can present the next insights:

  • Optimum sizing of energy storage in utility-scale methods
  • Battery capability degradation and augmentation methods to maximise income and minimise bills
  • Income stack evaluation from:
    • Wholesale energy markets with hourly and sub-hourly pricing
    • Capability markets equivalent to useful resource adequacy within the CAISO market
    • Energy buy agreements, together with shaping or time of supply capability injection necessities
  • Strong sensitivity evaluation to display tasks for financial viability and de-risk inner price of return

Inside energy storage, UL is greatest recognized for UL 9540A, a check technique for evaluating thermal runaway fireplace propagation in battery energy storage methods (BESS).

Trina Storage-Power Electronics partnership targets 1GWh BESS deployments by end of next year


Trina Storage, the energy storage division of {solar} PV producer Trina {Solar}, has shaped a partnership with {solar} inverter producer Energy Electronics to collectively deploy battery storage.

The vertically-integrated Chinese language PV firm – a member of the ‘Solar Module Super League’ of main producers as coined by our colleagues over at PV Tech – mentioned at present that it’s going to deploy over 1GWh of battery energy storage system (BESS) installations by the top of 2023 that are built-in with Spain-headquartered Energy Electronics’ PCSK inverters.

The 2 firms signed a letter of intent (LOI) for the settlement to hold out the deployments collectively ultimately week’s Intersolar Europe present in Germany.

On the occasion, Trina Storage was showcasing Elementa, its grid-scale BESS resolution and launching it officially to the mainland European market, though it has already been utilized in a efficiently commissioned 50MW BESS project in Cambridgeshire within the UK.

The corporate mentioned a US launch is coming quickly.

Elementa is a fully-integrated and modular resolution designed for simple plug and play set up.

Structure & offtake challenges for UK's 7.2GW co-located storage pipeline


Co-located storage is prone to develop as a proportion of the UK market with 7.2GW of tasks within the pipeline, however structuring offers and offtake agreements presents a fancy problem in response to a venture developer.

The pairing of {solar} or wind with storage is at a reasonably early stage within the UK. Lower than 10% of its 1.7GW of operational battery energy storage methods (BESS) is co-located with wind or {solar}, totalling 158MW. And most present co-located storage tasks have two separate grid connections with a restricted quantity of shared infrastructure.

However there are 317 tasks totalling 7.2GW co-located with {solar} or wind within the improvement pipeline, round one fifth of the entire (figures from {Solar} Media’s UK Battery Storage Projects Database).

Undertaking builders are more and more taking a look at creating websites which share grid capability however this presents a myriad of complicated challenges together with structuring offtake agreements, as our supply – an worker with a senior administration duty for energy storage at a serious worldwide renewables and storage developer – defined, talking anonymously.

Grid connection queue

“Clearly, you want the import capability for battery storage. That’s a little bit of a problem, as a result of retrospectively including import capability to your present grid software may put you additional again within the queue, which isn’t a great place to be in,” they stated.

“With the intention to maximise the return on funding of a co-located venture the battery must pursue numerous income streams which depend upon grid import capability. Let’s say you have got already a PV venture in improvement and have a grid connection supply. Then you definitely wish to add storage and request extra import capability. Relying on the DNO and particular connection this might considerably delay the connection date and improve the quantity of forecasted curtailment. So you have to be properly privy to the right way to strategy this matter”. 

SPV construction

The second query when creating a co-located venture is deciding the right way to construction the deal into particular goal automobiles (SPVs), difficult by the actual fact you have got two property plus a grid connection, as our supply defined.

“There are principally two choices: you may have the grid connection, {solar} and storage multi functional single SPV which lets you optimise the plant extra holistically by for instance saving capex on infrastructure and know-how gear and likewise to cost the battery from {solar}. Or, if you wish to have doubtlessly two totally different homeowners for PV and battery you’d most likely have three SPVs. One grid SPV which offers capability to the PV SPV and the battery SPV.”

Co-location with wind (pictured) is prone to grow to be extra prevalent in future within the UK because the market’s priorities shift to extra energy-based functions. Picture: Fluence.

Offtake settlement

However the offtake settlement is the actually difficult half, our supply defined, and above all must be as easy and de-risked as attainable for the longer term long-term proprietor.

“You’re combining the standard utility world of 5 or 10 yr energy buy agreements (PPAs) for the PV with AI algorithm-based totally automated buying and selling and bidding methods introduced by small startups for the BESS and the query is the right way to work that out,” they stated.

“From the venture SPV authorized entity perspective, you don’t need two unbiased contracts which then need to battle for the grid connection after which if one thing goes mistaken finger pointing begins, proper? From the long run proprietor’s perspective, this isn’t engaging. So you have to discover a manner that duties and all what-ifs and potential dangers are very clarified and minimised.”

“Ideally, you have got one celebration who provides you one contract providing each; is in-house able to providing you with a long run mounted PPA worth, with the in accordance steadiness sheet or credit score worthiness to again this, but in addition is ready to do the flowery new AI stuff with batteries to create revenues on the flexibleness aspect.”

This mix a minimum of within the UK market is considerably uncommon, they added, and so that you sometimes have to discover a mixture of gamers who supply a mixed contract. Energy-Storage.information has not too long ago interviewed among the predominant BESS optimisers on the market like Habitat Energy and Flexitricity that take property into market on behalf of their shoppers.

Our supply: “There are normally two predominant choices: you may go and choose your two most well-liked events from each worlds and have them working collectively on the identical grid connection. They then additionally have to have to ascertain agreements between one another.”

“One key danger to take care of here’s what if one of many two events falls away which obligations and pursuits does the opposite celebration have to interact with a alternative celebration as shortly as attainable to make sure you don’t have a stranded asset? It’d look much less dangerous to have a single path to market supplier who takes on each PV and storage, however then you’re doubtlessly not in a position to choose the perfect of each worlds.”

Most co-located storage tasks pair with {solar} PV as wind requires rather more biking and likewise a a lot bigger battery. Anesco has delivered a number of giant co-located tasks whereas BayWa r.e. acquired tasks from Concord Energy and JBM in April 2022 and July 2021, respectively.

Co-location with wind might are available just a few years when the market strikes extra in direction of energy buying and selling, our supply added. Some 80-85% of BESS revenues are nonetheless from grid ancillary providers according to Gore Street Capital, one of many main traders available in the market.

The Swiss-American startup is creating a novel energy storage know-how primarily based on gravitational energy. Though it had previously said shortly before listing that it hasn’t but perfected its grid-scale energy storage system (ESS) product, EVx, the corporate stated extra lately that construction work has begun on a 25MW/100MWh project in China.

In keeping with its quarterly monetary outcomes which it introduced a number of days in the past, a licensing settlement from Atlas Renewable  –  a US firm particularly set as much as create connections between the US and Chinese language renewable energy industries – drove Q1 2022 revenues of US$42.9 million.

Versus a GAAP web lack of US$20.1 million largely regarding the price of its merger with particular goal acquisition firm (SPAC) Novus Capital Company II, its GAAP working revenue was US$20.8 million for the quarter.

Its transaction with Novus Capital which took the corporate public included US$50 million non-public funding into public fairness (PIPE) commitments from every of Atlas Renewable and Korea Zinc. Energy Vault ended the quarter with US$303.5 million money and money equivalents.

Energy Vault additionally famous that it’s in discussions with Indian state-owned power producer NTPC and Enel Green Power relating to doable deployments in India and the US respectively. An 18MW/36MWh undertaking in Texas with Enel is predicted to interrupt floor in September, the corporate stated.

It’s also creating software program options below its energy administration platform division to which it has appointed energy storage and cloud computing industry veteran John Jung as head and in addition made a variety of key govt and advisory board hires over Q1.

“We made vital progress on our progress technique this quarter as we signed a number of new agreements and MOUs with world-class clients who additionally selected to make massive investments in Energy Vault, together with with Korea Zinc and Atlas Renewable, which expanded our footprint in Australia and China, the place we broke floor on our first EVx deployment in March 2022,” CEO Robert Picconi stated.

The corporate expects to make additional bulletins on deployments for EVx and its software program platform Energy Vault Options within the US, China and Australia throughout 2022, Picconi claimed.
