A battery may cover a factory\u2019s largest isolated demand event and still miss a smaller event later that day. The first discharge changes the energy available for the second. If the site cannot recharge in between, a sizing calculation that treats each peak independently can promise a result the dispatch cannot deliver.<\/p>\n

BESS multiple-peak dispatch therefore needs a chronological review. Follow battery energy, charge capability, site import and protected reserve through the actual sequence. The question is not only \u201cHow large is the biggest peak?\u201d It is \u201cWhat condition is the battery in when each relevant peak arrives?\u201d<\/p>\n

Define the target at the billing meter<\/h2>\n

Identify the tariff\u2019s demand measurement and the meter that determines the bill. Establish whether the target is a site import ceiling, a time-dependent threshold or another contract-specific rule. Do not substitute the PCS power reading for the billing-meter requirement without explaining the boundary.<\/p>\n

SAM\u2019s electricity-rate documentation<\/a> distinguishes demand and energy calculations and describes billing-demand inputs. Its model conventions must be checked against the actual local tariff; software defaults are not the customer\u2019s electricity agreement.<\/p>\n

Jest to peak-shaving sizing guide<\/a> establishes the basic power and energy requirements. The chronological review below addresses the extra constraint created when several events compete for the same stored energy.<\/p>\n

Build an event ledger before choosing a capacity<\/h2>\n

Keep the actual interval-load trace as the underlying evidence, then use a concise event ledger to explain the difficult sequences to decision-makers. The ledger should not replace the time-series simulation. It makes the critical constraints visible rather than hiding them behind one annual savings value.<\/p>\n\n\n\n\n\n\n\n\n\n

After the final event<\/td>\nReadiness for the following period<\/td>\nDoes recovery create a new demand or reserve shortfall?<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

At every step, distinguish nominal storage from energy available for the selected service. Reserve policy, operating limits and measured condition can restrict the portion that may be dispatched. Do not spend the same reserve once for tariff savings and again for outage support in the financial model.<\/p>\n

The recharge gap is a power constraint as well as a time constraint<\/h2>\n

A long gap between peaks is useful only if charging is permitted and sufficient power is available. When factory demand remains near the import ceiling, charging at the battery\u2019s maximum rating can defeat the purpose of peak shaving. The controller may need to reduce charging, leaving less restored energy than a capacity-only calculation assumes.<\/p>\n

SAM\u2019s behind-the-meter battery dispatch documentation<\/a> describes charging and discharging against grid-power targets subject to battery capacity and SOC. This is a modelling framework, not a guarantee that a particular EMS implements the same algorithm.<\/p>\n

Review recharge against transformer and connection headroom, allowed grid charging, solar availability, battery charge limits and tariff timing. A charger setting is not proof that the site can continuously supply that power. Also check whether auxiliary loads lie inside the constrained meter boundary.<\/p>\n

For a cabinet-scale installation, use the configuration review in sizing a commercial BESS<\/a> to identify the limits that belong in this chronological calculation. A system\u2019s model name cannot establish the usable energy or recharge conditions of the project.<\/p>\n

Test imperfect forecasts, not only a perfect replay<\/h2>\n

A retrospective simulation can know tomorrow\u2019s demand because the entire historic trace is already present. A live controller has forecasts, current measurements and an operating policy. Ask whether the quoted result assumes perfect information, a day-ahead forecast or a fixed schedule, and how forecast error changes reserve allocation.<\/p>\n

A sensible review includes unexpectedly early demand, a longer-than-usual production run and reduced recharge availability. These should use actual observed sequences where possible. Hypothetical cases must be clearly labelled and must not be represented as site measurements.<\/p>\n\n\n\n\n\n\n\n\n\n
