II.A.2.b Hypo<strong>the</strong>tical DG (< 1 MW) Cases<br />
The technologies typical <strong>of</strong> those that form <strong>the</strong> current installed base <strong>of</strong> smallscale<br />
DG (< 1 MW) in California are diesel and NG ICEs and NG turbines. The only<br />
technologies that are certified by CARB for sale and installation in California after 2003<br />
are microturbines and fuel cells. While each <strong>of</strong> <strong>the</strong>se technologies can be operated in a<br />
number <strong>of</strong> different operational modes (e.g., peaking, load-following or baseload), for<br />
this assessment, we model <strong>the</strong>m in continuous (baseload) mode for consistency with our<br />
treatment <strong>of</strong> <strong>the</strong> existing units. 10 Each technology class is modeled as if it were colocated<br />
at <strong>the</strong> site <strong>of</strong> <strong>the</strong> existing units. In addition, each is modeled at <strong>the</strong> city halls <strong>of</strong> <strong>the</strong><br />
eleven most populous cities in California. Figure 6 displays <strong>the</strong> locations <strong>of</strong> <strong>the</strong>se city<br />
halls, labeled by <strong>the</strong> city name. Table 9 summarizes <strong>the</strong> background characteristics <strong>of</strong><br />
each <strong>of</strong> <strong>the</strong> five technologies types modeled as hypo<strong>the</strong>tical DG cases. Figure 7 depicts<br />
four <strong>of</strong> <strong>the</strong> five small-scale DG technologies.<br />
10 In fact, DG technologies are marketed as useful baseload electricity sources (e.g., Capstone Turbine<br />
Corporation, 2003).<br />
