Feature overview

Everything new in HOMER Front 1.6

Eight coordinated capabilities, delivered as one integrated release.

  1. 1

    Imperfect foresight

    More options to build the expected production depending on the type of market.

  2. 2

    Multiple TOD contracts

    Combine obligations and dispatch pathways.

  3. 3

    Multi-year participation

    Vary market assumptions by project year.

  4. 4

    RT volume knob

    Steer RT attribution relative to DAM.

  5. 5

    Ignore cycling cost

    Explore accelerated cycling scenarios.

  6. 6

    Fixed block duration

    Commit across complete bid windows.

  7. 7

    DAM display logic

    Show DAM inputs only when relevant.

  8. 8

    Self-consumption

    Model condition-dependent auxiliary loads.

1–3 · Market realism and structure

More realistic forecasts, contract structures and lifetime assumptions.

1

Imperfect foresight

Compose the next 48-hour forecast from Week-1, Day-1 and DAM signals. DAM contribution can be adjusted or disabled, while forecast and realized prices can diverge to represent price uncertainty.

Forecast quality set to 100% with forecast model weights: Previous Day Price 60%, Previous Week Price 40%, Current Market price 0%
Set forecast quality and weight the previous-day, previous-week and current market prices.
2

Multiple simultaneous TOD contracts

Model multiple dispatch mechanisms and obligations in parallel. Allocate distinct energy shares and prices to each Time-of-Delivery arrangement, and separate dispatch by technology when required.

3

Multi-year market participation

Vary Storage Throughput (Activation), Probability of Winning Auction and BESS capacity availability by project year, replacing one static lifetime assumption.

BESS Throughput Schedule dialog with three throughput levels painted on a month-by-hour grid, above the Storage Throughput and Probability of Winning Auction inputs with Timeseries and Schedule buttons
Schedule BESS throughput by month and hour, or load Storage Throughput and Probability of Winning Auction as time series.

4–8 · Optimization control

More control over dispatch, participation and operating loads.

4

RT volume knob

Set Real-Time market volume relative to DAM, guiding realistic energy allocation across markets based on available volume.

Energy Market Configuration with DAM 90 and RTM 10, and capacity bid templates Aggressive 90/-/10, Concentrated 70/-/30 and Balanced 50/-/50
Pick a capacity bid template or set the DAM, FMM and RTM shares directly.
  1. 5

    Ignore cycling cost

    Optionally remove the cycling-cost constraint to test more aggressive BESS cycling and an accelerated modeled break-even.

  2. 6

    Fixed block duration

    Represent regulation markets such as FCR, where the BESS commits to the complete bid window, typically four hours, rather than participating hour by hour.

  3. 7

    DAM display logic

    Display Day-Ahead Market percentages only when DAM is active, keeping inputs and results clearer.

8

Self-consumption

Differentiate auxiliary consumption by temperature and BESS operating state: idling, charging or discharging.

Model Self-consumption panel: define 12×24 self-consumption limits, select a period, paint when each limit applies on a month-by-hour chart, and import a price time series per limit
Define self-consumption limits, paint when each one applies across the year, and attach a price time series to each.

Release foundation

Major stabilization behind the new capabilities.

A broad stabilization effort strengthens calculation integrity, market settlement, reporting consistency and product resilience.

Calculation integrity

Grid sales totals, export-limit behavior, C-rate and capacity values.

Market settlement

TOD allocation and penalties, aFRR Down and Reg Down expense.

Results consistency

UI versus Excel, decimal separators and production versus development alignment.

Product resilience

1.5 stabilization QA, security alerts and incident workflow.

Major defects removed+More consistent results=A stronger production foundation
