 Dear Friends,
We have an exciting opportunity for you to help us fund future HOMER enhancements, with a few clicks of your mouse. HOMER is entered in all three areas of GE’s Ecomagination Challenge to invent the best next generation electric grid.
We would be grateful for your vote in any or all categories:

| HOMER Energy and CU to model future energy scenarios for City of Boulder |
 |
| Boulder, Colorado |
HOMER Energy and the Renewable and Sustainable Energy Institute (RASEI) at the University of Colorado are analyzing energy scenarios that estimate the feasibility, costs, and CO2 implications of adding more renewable resources to Boulder’s power mix. The research project, led by Dr. Paul Komor and supported by Dr. Rebecca Johnson, will model power sysems that combine micro-grid and smart grid technologies with multiple types of distributed and renewable power generation and storage technologies. Because the range of future energy options is so complex, simulation modeling is essential for planning; the researchers have chosen HOMER as their modeling software. Learn more |

| Wind-Diesel for Alaska Villages |
 |
| Banner Wind Project: Nome, Alaska |
HOMER Energy will be working with the Alaska Energy Authority (AEA) to analyze wind-diesel systems for remote native communities. Until recently these communities have relied entirely on diesel for their energy needs, but fuel costs are rising rapidly. In 2009 diesel prices reported by rural utilities averaged $4 to $5 per gallon with some communities paying more than $7, including delivery costs. The HOMER software is being widely used in Alaska to realize wind energy’s promise of free fuel, predictable energy prices and lower energy costs overall. Learn more |
| HOMER Software Tip: Combined Heat & Power |
| To model a combined heat and power system (CHP) in HOMER, add a Thermal Load on the Add/Remove window and go to the Fuel tab of the Generator Inputs window and enter a Heat recovery ratio greater than zero (the default). HOMER defines the Heat recovery ratio as the percentage of the waste heat that is recoverable. To avoid any possible unmet thermal load HOMER will add a boiler and use it whenever there is insufficient waste heat to meet the thermal load. The CHP reduces the system’s net present cost by reducing fuel use on the boiler. If the system also has a secondary load controller (dump load) you can also use that energy to meet the thermal load by checking the “Allow excess electricity to serve thermal load” box in the Other settings section of the System Control Inputs window.
