Behind the meter storage right sizing and revenue stacking
Our core practice, for factories, science park tenants, cold chain operators, data centres, hospitals and other large electricity users. We reconstruct how the site consumes power before deciding how storage should be deployed.
- Interval load analysis and profile reconstruction, including sites whose measured profile has already been distorted by existing storage, demand response, curtailment or on site generation
- Contract capacity strategy and suppression of over contract penalties
- Time of use arbitrage, demand charge control and solar self consumption modelled as separate value streams rather than added together
- Charging headroom assessment, which kills more projects than equipment price does
- Dispatch simulation with state of charge floors, round trip efficiency and degradation built into the tariff calculation rather than applied afterwards
- Sizing to the point where extra energy capacity stops producing proportional return
- Return, payback and utilisation metrics, including equivalent full cycles per year, discharge utilisation and cycle depth
The deliverable is a size and an operating rule. It is not a product recommendation.
Renewables plus storage development
We treat solar and storage as one energy delivery asset rather than two equipment packages.
- Site and land capacity screening, generation to storage ratio, and coupling architecture
- Solar to storage energy flow modelling and delivery window analysis
- Grid charging assumptions, curtailment exposure and replacement power risk
- Interconnection concept covering collector system, substation and voltage level
- Development phasing, offtake structuring, and preliminary capital and operating cost modelling
The question is not how much capacity can be installed. It is what the combined asset can be contracted to deliver, and what happens on the days it cannot.
Grid services and virtual power plants
A battery earns more than arbitrage only where the market rules, the dispatch obligation and the physical asset agree with each other. In several Asian markets right now they do not.
- Service eligibility and market entry pathway, tested against the actual equipment rather than the nameplate
- Power, duration and response time qualification
- State of charge reservation, availability, and conflict with host site obligations
- Revenue stacking, and more usefully, revenue stack conflicts
- Aggregation architecture and virtual power plant design, keeping system operator, market operator, aggregator and asset owner responsibilities separate
- Baseline methodology, performance verification, and exposure to non performance penalties
- Registration and qualification workload, which is normally underestimated by a wide margin
Two examples of what this work catches. A 0.5P system rated 5 MWh could not bid into a frequency regulation product because its 2.5 MW power ceiling sat below the 3 MW qualification threshold. That was visible on the datasheet and absent from the commercial case. Separately, in Taiwan the day ahead ancillary service products that carried early storage business cases have cleared at zero for extended periods, which changes what a new front of meter project can honestly promise an investor. The Taiwan page sets out the numbers. A virtual power plant is a set of contractual obligations before it is a software product. If the dispatchable field resources and the responsibility split are unresolved, what gets built is a dashboard.
Microgrids and island systems
Off grid and weak grid projects are operating system problems rather than generation problems. Adding intermittent capacity to a small grid without control, reserve and operating coordination creates new instability.
- Whole system assessment covering demand, renewable output, storage, conventional generation, distribution constraints, operating responsibility and recovery from contingencies
- Solar, storage and conventional generation integration, and fuel displacement analysis
- Grid forming, black start and restoration concepts
- Modular architecture sized for local logistics, including whether containerised equipment can physically reach the site
- Distribution utility coordination, load growth scenarios and tariff or subsidy interaction
- Remote operation, monitoring and maintainability under real local staffing conditions
- Regulatory route to operate, which differs sharply by country and is covered on each market page
In the Philippines this work runs through the Microgrid Systems Act framework, where a provider is not treated as a public utility and does not need a congressional franchise, but does need an authority to operate from the regulator and normally has to win a competitive selection process. That regulatory route shapes the technical design more than the site conditions do.
Market intelligence and regulatory tracking
Storage economics in Asia are set by instruments that change every few months. A feasibility study built on last year's rules is not conservative, it is wrong.
- Market screening, sizing and segmentation for a specific product or project type
- Regulatory tracking on named instruments, with effective dates and what each one changes for a project already in development
- Tariff and revenue mechanism review, including auction, feed in tariff, capacity payment and ancillary service design
- Grid code and interconnection requirement review
- Pipeline, partner and stakeholder mapping
- Commercial model comparison across markets
- Risk register development and local execution planning
- Decision memoranda for boards and investment committees
We separate verified fact, working assumption, and item requiring local confirmation, and we label which is which in the document. Anything we cannot source, we say we cannot source.
Capital formation and investment assessment
We work on the capital structure with the same scrutiny we apply to the technical case.
- Fund and vehicle structuring, including general partner and limited partner architecture, tranching, return target design and development fund concepts
- Investor materials in English and Traditional Chinese, including pitch decks, information memoranda and decision papers
- Technical and commercial due diligence on target pipelines and platforms
- Listing vehicle and de-SPAC assessment, covering trust mechanics, redemption risk and sponsor governance
- Introduction, commission and warrant agreements between sponsors, brokers and project owners
- Sensitivity and downside modelling that a technical adviser is willing to sign rather than a placement agent
Storage funds fail diligence on the operating assumptions rather than the capital structure. The dispatch model has to survive the same scrutiny as the waterfall.
Product compliance and market entry for suppliers
For battery, power conversion system and inverter manufacturers entering a new Asian market, the barrier is rarely the product. It is the certification chain and the utility approved product list.
- Certification gap analysis, including the scope difference between IEC 62477 and IEC 62109 for storage power conversion systems, the distinction between UL 9540 and UL 9540A, national marks such as BSMI in Taiwan and TISI in Thailand, and Japan's JC-STAR cybersecurity label, which is becoming a grid connection precondition rather than a marketing point
- Utility and grid code compliance, interconnection review requirements, and distribution utility approved product lists
- Battery and power conversion system compatibility review, covering 1500 V architecture, battery management to converter protocol alignment, and protection coordination
- Competitive and price stack benchmarking, from cell cost through to installed cost
- Phased twelve month market entry plans naming the approval bodies and realistic queue times
Time to market in most Asian storage markets is set by the certification queue rather than the sales cycle. Manufacturers routinely plan for the second and budget for the first.
