COMPARE & SIZE

Storage laboratory

Fast-load laboratory

15-MINUTE COMPARISON

Compare engines alone, BESS, and BESS + flywheel against identical sharp load changes. Uses the current plant settings and day-one noon demand; removes outages and automatic service for this controlled test. Utility settings are retained in all cases.

Load step · %

Battery and flywheel sizing comes from Plant settings, even when their enable boxes are off. Results describe real-power response, not frequency stability or trip immunity.

Storage sizing sweep

15 CONTROLLED CANDIDATES

Find sizes that meet a service target in the 15-minute fast-load test above. Sweep battery power and energy around plant settings, then compare hybrid banks with BESS-only alternatives matched for total power, full usable AC energy and starting usable AC energy.

Minimum service · % Longest interruption · seconds

Uses the fast-load step percentage above. Targets can be changed after calculation. A passing case meets both targets in this test only.

Seven-day validation

Use “Validate 7 days” on a candidate after the sweep. Validation restores the captured daily load, outage schedule and maintenance settings. Fast-load pulses are not repeated. Storage and engine state continue across midnight.

No candidates validated yet.

OPERATIONS & MAINTENANCE

Outage schedule

Outage & maintenance editor

Edit events in elapsed hours (16.5 = day 1 at 16:30; 40 = day 2 at 16:00). Increase the study horizon to fit longer outages. Equipment IDs: engine-1, block-1, bus-1, utility-1, bess-1 or flywheel-1. Engine and block numbers must exist in the configured plant; Storage must be enabled for an outage on that storage type.

Import JSON

Changes apply on the next run. Save the completed study to retain its schedule. Import replaces the editor schedule; files stay local.

Overlapping events are allowed. A block outage disconnects all its engines; a common-bus outage interrupts all sources. Planned maintenance is labeled separately but has the same unavailability behavior; advance preparation is not modeled.

Studies & costs

Saved studies & operating costs

Compare completed runs using one set of illustrative USD rates. Edit these to match your project. Pricing does not change dispatch.

Study name

Up to 12 studies, saved only in this browser. Restore settings, then run to recalculate.

Gas price and billing details are editable in Plant settings. Engine LHV consumption is converted internally to the selected tariff basis. Startup fuel is already included in gas. Maintenance covers modeled running time including cooldown. Cycling is an assumed allowance.

Costs exclude capital, fixed costs and restoring initial battery charge. Positive battery draw means stored energy was consumed. Compare service, excess power and battery draw alongside cost; this table does not rank a winner. Matching events have the same equipment IDs and times; changing block size changes the capacity lost. Rates reset to illustrative defaults on refresh.
