#1 - Avoided / Marginal Costs<br />

• The Issue<br />

– Marginal cost intended to reflect the avoided cost of<br />

supply for that measure<br />

• Options & Challenges<br />

– Utilities often use “average” marginal costs<br />

• Seasonal marginal costs<br />

– Summer / flat loads have a different cost than winter<br />

– Is MC of fossil fuel the “right” screen?<br />

• Some jurisdictions have higher feed-in rates for green energy<br />

• CST allows use of higher MC from other utilities<br />

• <strong>FortisBC</strong> – MC gas $7.03 vs $9.90 - $15.28 for biogas (<strong>2011</strong>)
