Title: Shades of Green Update


1
Shades of Green Update
  • J.P. Blackford
  • The George Washington University
  • School of Engineering and Applied Science
  • DEED Intern

2
Shades of Green Update Agenda
  • Whats New
  • Where we are in 2005 the Update
  • Proposed New Additions
  • Where do we go from here??

3
Shades of Green Whats New?
  • Biggest change from 2001 Shades
  • Non-Utility Generators

4
Shades of Green The Update
  • Public Power still leads the way with hydro and
    has the second lowest coal generation
  • Non-Utility Generators have very high Natural Gas
    generation

5
Renewable Capcity
  • Public Powers position remained very strong, but
    showed no significant growth (but, neither did
    IOUs or Co-Ops).
  • Vast majority of renewables are Hydro

6
A bit more on Renewables
  • We lead the way with Hydro
  • We fall behind on non-hydro renewables to the
    Non-Utility generators

7
Fossil Fuel Mix -- Capacity
  • PP uses less coal than all but Non-Utility
  • PP uses more oil than the others
  • But, the fuel mix isnt really all that
    significant

8
Fossil Fuel Mix -- Generation
  • PP has significant non-utilized gas capacity
  • Peaking units are gas-fired
  • This is a snap-shot of one year
  • PP coal generation has declined, IOUs increased,
    Co-Ops remained steady

9
Operating Coal Capacity Age
  • Obviously, plants have gotten older, so the
    graphs show that change

10
Emissions Sulfur Dioxide
  • PP retains its rank as the lowest Sulfur Dioxide
    emissions

11
Emissions Nitrogen Oxides
  • PP is still lower than IOUs and Co-Ops, but, is
    higher than Non-Utility Generators

12
Emissions Carbon DioxideBased on Capacity
  • Weve improved!
  • But, the Non-Utility generators emissions are
    lower than ours.

13
Emissions Carbon DioxideBased on Generation
  • The trend between PP, IOUs and Co-Ops remains the
    same, but, Non-Utilities are slightly better than
    PP

14
Hydroelectric Capacity
  • PP still has approximately 4 times the hydro
    capacity as IOUs

15
Non-Hydro Renewables
  • Non-Utility Generators have significantly more
    non-hydro renewables.
  • PP has increased its non-hydro capacity (by about
    20), while IOU capacity decreased and co-ops
    remained nearly the same

16
DSM
  • Same general trend, though PP spending did
    decrease.

17
Landfill Gas
  • Currently
  • 370 LFGE projects already exist and another 200
    are under development
  • In 2003, these projects removed over 17.7 MMTCE
    of methane annually, which equates to removing
    emissions equivalent to 14.3 million cars,
    planting 19.3 million acres of forest, or
    preventing the use of 152 million barrels of oil.
  • Previously
  • 317 LFGE projects existed and another 54 are
    under construction

Landfill gas may prove to be more significant
since new EPA data shows that the heat trapping
potential of methane is 23 times as strong as
carbon dioxide this is up from 21.
18
Whats New??
19
Zero Emissions Capacity
  • This counts Hydro and Nuclear.
  • PP clearly leads the way in these generating
    technologies that have no emissions

20
Mercury
  • Graph considers Fossil Fuel generation only.
  • PP has significantly lower mercury emissions than
    the other generators.

21
Green Pricing
  • PP has significantly more utilities offering
    green pricing programs to their customers

22
Green Pricing Continued
  • PP average green pricing premium is less than
    IOUs or Co-Ops.
  • This is misleading, though, due to IOU solar
    programs which have significantly higher
    premiums.
  • Looking at the median, the premiums are similar

23
Renewable Portfolio Standards
  • Disclaimers
  • Hydro may or may not be counted in all of the
    state RPS standards
  • Some figures are misleading due to limited PP
    presence in some states
  • Credit may or may not be given for existing
    renewables in the proposed RPS

24
Why are we Green?
  • Things we really cant control
  • Location
  • Weve got a lot of Hydro capacity due to where
    were generating our power (Pacific NW, for
    instance)
  • Age
  • We got into the generation side later, so our
    plants are newer, and therefore cleaner

Still
25
Conclusions
  • Were still greener than the IOUs and Co-Ops
  • Thats great, but, it poses a bigger question

26
Where do we go from here?
  • How do we want to proceed on the Shades of Green
    Update
  • Case Studies
  • Small Member Contributions

27
The spin on the Update
  • Were still Green, but look at what were doing
    to become even greener
  • Case Studies (more on that soon)
  • Policy Pressures that PP will be facing
  • GHG intensity
  • RPS
  • Others?
  • Opportunities for PP
  • Landfill Gas
  • Anything Else?

28
Case Studies
  • We want to show that while PP is green, were
    trying to be greener
  • Tree Power
  • Holland (MI) mercury thermometer and industrial
    switch program
  • Others??
  • These are likely programs that were not getting
    credit for elsewhere!

29
Small Member Contributions
  • How can we collect what our smaller (lt25 MWh)
    generators are doing?
  • Most are exempt from reporting
  • Voluntary reporting may be too burdensome for
    smaller generators

30
Anything else?
  • Other items to include in the update to Shades of
    Green
  • Questions?
  • Comments / Suggestions?
