AI data centre, Taoyuan, Dayuan, 25 MW

Problem
map stakeholder roles and the competitive landscape for a 25 MW AI data centre in Dayuan, Taoyuan.

Work

mapped storage and rooftop solar roles across the project, catalogued supply typologies, and profiled the Taiwan specific market players active in this segment.

roles, not technology, were unresolved

the open questions were about who does what, which party owns storage, which owns rooftop solar, and how supply is contracted, rather than about which technology to deploy.

Consequence
the deliverable was a role map and player landscape the client could use to structure procurement, ahead of any technical sizing work.

Bakeware and baking equipment manufacturer, Taichung

Problem
size behind the meter storage and review the time of use economics for a bakeware and baking equipment manufacturer.

Work

analysed the time of use bill, tested storage configurations against the plant's production schedule, and reviewed the resulting economics.

batch production, not a flat load

demand followed the plant's batch production schedule rather than a flat industrial load, which shifted the best charge and discharge windows away from the tariff's default assumption.

Consequence
the dispatch schedule was built around the production calendar rather than the tariff's standard peak and off peak windows.

Full case study

Cement manufacturer, Hualien, eastern Taiwan

Problem
size behind the meter storage for a heavy industrial cement plant on a high voltage tariff.

Work

reviewed the plant's contract capacity history, decomposed the time of use bill into its component charges, and built a revenue stack around peak shaving and time of use arbitrage.

peak shaving, not arbitrage

on this tariff, peak shaving against the existing contract capacity carried most of the modelled revenue stack, with time of use arbitrage as a secondary contributor rather than the main case.

Consequence
the sizing case was built around demand charge avoidance first, with arbitrage revenue treated as upside rather than the primary justification.

Full case study

Chemical plant, southern Taiwan, science park facility

Problem
build a defensible dispatch and savings model for a large science park facility using fifteen minute interval data.

Work

developed peak shaving and over contract suppression logic with state of charge floors and round trip efficiency integrated into the tariff calculation, and added customer baseline calculation and utilisation metrics.

19 percentdischarge utilisation

Approximately 19 percent discharge utilisation and around 70 equivalent full cycles per year. The battery was being paid for as infrastructure and used as insurance.

Consequence
utilisation replaced return on investment as the first metric reviewed at subsequent sizing meetings.

Full case study

Data centre campus, 110 MW, Taiwan

Problem
scope power and storage for a 110 MW data centre campus under Taiwan's high voltage time of use structure.

Work

assessed how storage fits a large, high load factor site, and identified where behind the meter value exists under the high voltage tariff.

load factor compresses the case

a high, steady load factor leaves a narrower gap between peak and average demand than lower load factor industrial sites, so the pool of behind the meter value available to storage is smaller in proportion to the site's size.

Consequence
the scoping work flagged resilience value and grid interconnection timing as more material to the project than time of use arbitrage.

Full case study

Data centre, northern Taiwan, 5,000 kW

Problem
establish whether behind the meter storage could be justified at a data centre site with a 5,000 kW Taipower contract.

Work

rebuilt a corrected 8,760 hour load profile at a load factor of 0.89, ran a full dispatch simulation under high voltage three tier time of use, and modelled land to megawatt density scenarios and the effect of the free supplementary off peak contract allowance.

near zerointernal rate of return

Pure time of use arbitrage returned a near zero internal rate of return at roughly 350 US dollars per kilowatt hour installed, without subsidy. Additional off peak contract capacity widened the charging window without improving the return.

Consequence
the client stopped optimising charging headroom, which was not the binding constraint, and reframed the project around resilience value and a possible subsidy trigger.

Full case study

Second hand diesel generation barge, 40 MW, Philippines

Problem
assess a 40 MW second hand diesel generator barge for deployment, repowering, and its fit as dispatchable capacity.

Work

reviewed the barge's condition and repowering requirements, and assessed its fit as dispatchable capacity within the target grid.

dispatchability over efficiency

the case rested on the asset's value as fast, dispatchable capacity rather than on fuel efficiency, which is where a newer unit would have competed.

Consequence
the assessment framed the asset against reserve and dispatchable capacity needs rather than against a new build efficiency benchmark.

Full case study

Industrial site with two utility feeders, Kaohsiung

Problem
size storage for a site served by two separate utility feeder lines with independent contract capacity and metering.

Work

modelled each feeder's load and demand profile separately, checked how far the two feeders' peaks coincided in time, and combined the results into a single storage and dispatch strategy.

the peaks did not coincide

the two feeders' demand peaks did not line up in time, so a single combined capacity figure would have overstated the site's real exposure and misled the sizing case.

Consequence
the model kept the feeders separate through the demand analysis and only merged them once each side of the dispatch strategy was confirmed.

Full case study

Electronics manufacturing group, behind the meter storage and solar surplus, Philippines

Problem
recover value from underused rooftop solar generation for an electronics manufacturing group.

Work

assessed the existing rooftop solar installation's underused output, and built a behind the meter storage proposal aimed at recovering that value.

the asset already existed

the solar generation was already installed and underused, so the proposal was a revitalisation case built around an existing asset rather than a new build investment case.

Consequence
the economics were framed around incremental value recovery, which carried a lower bar than a new installation would have needed to clear.

Full case study

Energy infrastructure fund structuring, Asia Pacific

Problem
build investor facing structures and materials for storage and renewable infrastructure vehicles across Japan, Southeast Asia and Oceania.

Work

produced bilingual fund proposals across several mandates and ticket sizes, designed partner structures, tranching and return targets, reconciled competing prospectus drafts, and conducted diligence on a prospective listing vehicle and a first investment target.

operating assumptions

Diligence pressure concentrated on operating assumptions rather than on the capital structure.

Consequence
the technical model was rebuilt to the same standard as the financial model before the materials went out.

Full case study

Footwear manufacturer, Vietnam, industrial rooftop solar

Problem
surplus rooftop generation and commercial exposure under the site's rooftop solar offtake agreement.

Work

matched solar output to factory consumption, assessed minimum consumption and surplus energy treatment, compared time of use, solar capture, power factor and prospective capacity charge value streams across several all in one cabinet configurations, and modelled fifteen year returns and sensitivities.

not the best configuration

The largest configuration was not the best configuration. Contract structure and surplus recovery outweighed arbitrage.

Consequence
the recommendation was a phased approach with a defined trigger, since validated by the 2026 change to the surplus sale cap described on the Vietnam page.

Full case study

Forged aluminium wheel manufacturer, Yunlin

Problem
assess behind the meter storage for a forged aluminium wheel producer with a power intensive forging and machining load.

Work

profiled the demand driven by heavy forging and machining equipment, and assessed storage against the resulting load shape and tariff.

short, sharp demand spikes

forging and machining equipment produced short, sharp demand spikes rather than a smooth load curve, which made the storage power rating, not its energy capacity, the binding design constraint.

Consequence
the system was sized on power rating first, with energy capacity following once the spike behaviour was captured.

Full case study

Island wide grid development, Mindoro, Philippines

Problem
propose an island wide grid development path for Mindoro, moving the island up to the next service level.

Work

built the island wide grid development proposal, and paired it with a microgrid service case study designed as a replication template for comparable islands.

a template, not a one off

the case study was structured so the same method could be pointed at another island's grid without starting from a blank page.

Consequence
the client asked for a shortlist of comparable islands where the same template could be applied next.

Full case study

Grid flexibility and virtual power plant architecture, Philippines

Problem
define how distributed batteries, microgrids, renewable generation, controllable loads and backup resources could be aggregated into a workable flexibility platform.

Work

reviewed ancillary service and reserve use cases, designed aggregation architecture, separated system operator, market, aggregator and asset owner responsibilities, and specified a staged deployment path.

thinner than the software roadmap assumed

The platform concept was sound but the dispatchable field resource base was thinner than the software roadmap assumed.

Consequence
deployment was staged behind resource acquisition rather than behind software delivery.

Full case study

Industrial manufacturer, Yunlin, central Taiwan

Problem
size behind the meter storage to match a Yunlin manufacturing site's demand profile and tariff.

Work

analysed the site's billing history and demand profile, and matched storage size and configuration to the tariff structure in place.

tariff read before system size

getting the tariff structure right came first. once the billing components were correctly decomposed, the appropriate system size followed directly from the demand profile.

Consequence
the sizing recommendation was anchored to the corrected tariff read rather than to a generic capacity target.

Full case study

Off grid storage, Mindoro, Philippines

Problem
build a financial model for storage in an area outside the main transmission grid, under the small island and isolated grid operator framework.

Work

analysed the published 2025 to 2034 ancillary services procurement plan to extract storage eligible procurement rates by service type and grid region, assessed modular architecture, island logistics for heavy equipment, resilience and remote operation requirements, handled contract authentication and storage specific translation, and identified local assumptions requiring verification.

2.08 to 2.20pesos per kilowatt hour

No storage dispatchable reserve contract existed as a precedent, so regulator approved rates had to serve as the baseline. Regulating reserve rates, at roughly 2.08 to 2.20 pesos per kilowatt hour, sat above contingency reserve rates at 1.25 to 1.50, and the off grid framework tends to price above on grid benchmarks.

Consequence
the model states its baseline as a regulatory document rather than a market price, and flags that assumption on the front page rather than in an appendix.

Full case study

Retail and property group microgrid proposal, Philippines

Problem
propose a microgrid strategy for a large retail and property group across its site portfolio.

Work

surveyed the group's site portfolio for microgrid candidates, and built a proposal covering the sites with the strongest fit.

portfolio, not single site

the strongest economics came from treating the portfolio as a single pipeline rather than sizing each site in isolation, since scale improved procurement and financing terms across sites.

Consequence
the proposal was structured around a phased, portfolio wide rollout rather than a single flagship site.

Full case study

Rooftop solar billing reconciliation and storage case, Ho Chi Minh City

Problem
trace an unexplained extra charge on a Vietnamese manufacturing plant's electricity bill, running rooftop solar under a power purchase agreement, and assess whether storage could reduce it.

Work

matched the plant's interval data to the correct utility meter, since an early candidate meter looked plausible from its description but its bill was two orders of magnitude too small, then confirmed the match by reconciling roughly 271,800 kilowatt hours derived from the file against 277,200 kilowatt hours billed for the same period.
split the disputed charge into a standard reactive energy charge from low power factor, unrelated to solar, and a separate minimum consumption shortfall fee under the power purchase agreement, then traced the fee to a 75 percent minimum consumption commitment against projected output, against which actual consumption came in at 66.1 percent.
derived recoverable solar from two separate inverter monitoring platforms, since the utility's own portal does not expose behind the meter generation, then built a four layer storage revenue stack, time of use shifting, maximum demand reduction, charging from recoverable solar, and additional fee relief, and modelled two system configurations against it.

two charges, not one

the extra charge on the bill was not a single billing error. it was a standard reactive energy charge from low power factor, unrelated to solar, plus a separate minimum consumption shortfall under the power purchase agreement, worth roughly 292 million Vietnamese dong for the year once traced to its source.

Consequence
the dispute was redirected from the bill, which was correct, to what storage could realistically recover. an 800 kW, 800 kilowatt hour system reached roughly 30.7 percent return driven mainly by maximum demand savings, while a larger 1,000 kW, 2,000 kilowatt hour system gave more duration at a lower 13.8 percent. recovering the full consumption shortfall through storage alone needed close to 500 kW, 990 kilowatt hour of usable capacity, and only if the contract recognises stored solar as solar consumption.

Full case study

Solar plus storage, Visayas, Philippines, 40 MW

Problem
build a development case for 40 MW of solar plus storage in the Visayas under a fixed offtake price.

Work

sized generation and storage against a power purchase agreement price of 6.5 pesos per kilowatt hour, and modelled the resulting revenue picture.

6.5 pesos per kilowatt hourofftake price

the offtake price was fixed by contract, so the sizing question was how much storage that price could support, rather than what price the project needed to reach.

Consequence
the storage component was sized to the revenue the fixed price could carry, rather than to a target return set independently of the contract.

Full case study

Storage manufacturer market entry, Thailand

Problem
establish what a foreign storage manufacturer must complete before it can sell into the Thai market.

Work

mapped the two distribution utilities' approved product requirements, identified national standards certification gaps, assessed grid code compliance obligations, and produced a phased twelve month plan naming the approval bodies.
the current phase extends this into energy management system and power conversion system regulation, alongside a wider grid code study.

certification queue

The binding constraint on market entry was the certification queue rather than commercial readiness.

Consequence
the launch plan was rebuilt around approval milestones, and the sales hiring schedule moved back accordingly. the current phase of work is carrying that same approval first logic into the equipment's control and conversion systems.

Full case study

Textile manufacturer, Yunlin, Douliu, roughly 22,500 kW contract

Problem
determine the appropriate storage size under complex time of use, demand response and contract capacity conditions, for a site running a heavy round the clock base load.

Work

analysed billing across regular and supplementary contract capacity, modelled multiple power and energy configurations including 15 MW with 90 MWh and 15 MW with 60 MWh, and tested achievable contract capacity targets against the site's genuine base load.

below roughly 16,000 kW

The 50 percent free allowance on supplementary contract capacity removed a savings opportunity the original business case had assumed. Contract capacity targets below roughly 16,000 kW were unreachable at any battery size.

Consequence
two of the largest lines in the original model were removed. They were arithmetic errors in the tariff logic rather than optimistic assumptions, and the corrected case supported a smaller system.
