Zoom into your project area on the map. When you have zoomed-in far enough, drawing tools will become visible on the left side of the map.

Use the drawing tools to create a polygon for analysis. The polygon represents the boundary of your project and allows us to subset the data accordingly.

Below the map, select inputs for the C-BREC modeling app from the various dropdowns. These are the options that define what type of forestry practices and biopower generation to evaluate with the app. Selections from each category must be made before the app can be run.

When you have finished making your choices, click the 'Submit' button to start you analysis. When the results are available, the tables will be updated at the bottom of the page.

Thin From Above: remove the largest trees first, opening up the canopy for the understory.

Thin From Below: remove trees with the smallest basal areas first, for forest health thinnings or fuel reduction treatments.

Clearcut: remove the maximum amount of wood volume, while conforming to California forest practice rules and regulations.

In a clearcut, 100% of the available basal area is removed. For either type of thin, 20% to 80% of the basal area will be removed, depending on your selection.

The percentage of the residual biomass (branches, tops, breakage, etc) that is piled.

All Technically Recoverable: collect everything possible.

Piles Only: only collect piles.

Dry Grind: <= 50% moisture, ground, large project (>=1,000 BDT residue and >= 13 BDT per acre)

Green Chip: > 50% moisture, chipped, large project (>=1,000 BDT residue and >= 13 BDT per acre)

Green Grind: > 50% moisture, ground, large project (>=1,000 BDT residue and >= 13 BDT per acre)

Dry Grind, Low Density: <= 50% moisture, ground, small project (<1,000 BDT residue or < 13 BDT per acre)

What would have been done with the residue if not removed for biopower generation?

Left in Place: the residue would be left to decay in the field.

Prescribed Burn: the residue would be burned.

Current Generation Combustion Plant: must specify hauling distance.

Current Generation Integrated Gasification and Combustion Plant: must specify hauling distance.

Next Generation Thermochemical Plant: must specify hauling distance.

< 1MW Plant: must specify hauling distance.

What is the hauling distance from the project site to a power plant facility? If you select Nearest as the facility type, the distance is automatically calculated. If you select any other type of power plant facility, you can choose hauling distance in 40 km / 25 mile increments.

Specify whether the destination power plant facility has or will have CHP.

CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. CHP can be located at an individual facility or building, or be a district energy or utility resource. CHP is typically located at facilities where there is a need for both electricity and thermal energy. EPA
