Summary
 Successful organizations agree on goals and mission, then
concentrate on tactics.
 Start by understanding the environment.


Rising electric rates, rising fuel costs, concerns about excessive
fossil fuel use and global warming, manufacturing job loss, and fear
for our way of life.
Expect journalists and politicians to fix blame.
 Figure out how to fix the problem

Determine consensus goals

Identify opportunities to advance goals

Quantify the problem and opportunity
 Articulate a clear, elegant, mission
Three Key Power System Goals
 Availability of Energy Services
 Availability of Energy Services
 Availability of Energy Services
Subordinate Power System
Goals
 Limit capital expenditure
 Reduce rates
 Reduce fossil fuel use
 Reduce pollution
 Reduce global warming
 Reduce system vulnerability
 Reduce manufacturing job loss
What is the Problem?
Is it the conventional wisdom?
 Large generation has economies of
scale
 All power will flow through wires
 (New) ‘Technology is the Ticket’
President Bush, May 2005
 Free markets cannot provide the world’s
most second most important service
(Beer is first)
Assess the Power System
 Did power industry chose optimal
approaches in the past?
 What is best way to meet expected US and
world load growth?
 What are the effects of 100 years of
monopoly protection of electric
distribution?
 Compare options for meeting expected load
growth

Defining Recycled Energy
 Recycled energy is useful energy
derived from



Exhaust heat from any industrial process;
Industrial tail gas that would otherwise be
flared, incinerated or vented; and
Pressure drop in any gas

US Industrial Recycling Potential
 Recycled energy could supply 45 to 92
Gigawatts of fuel-free capacity – 13% of US peak
 Recycled energy is as clean as renewable
energy – no incremental fuel or emissions, but:



Capital costs are $500 to 1,500/kW, only 12% to 40% of
solar and wind generation,
90% load factors versus 14-40% for solar & wind
Recycled energy is both clean and economic option
for new power generation.
 EIA shows only 2.2 Gigawatts operating
Recycled Energy Case Study:
Primary Energy
 NiSource invested $300 million in six projects to
recycle blast furnace gas, coke oven exhaust in
four steel plants, 440 megawatts of electric
capacity and 460 megawatts of steam capacity.
 Steel mills save over $100 million per year and
avoid significant air pollution

The CO2 reduction is equivalent to the uptake of one
million acres of new trees.
 The projects are profitable; were recently sold for
$335 million to our firm
90 MW Recycled from Coke Production
Chicago in Background
Has US Power Industry Made
Optimal Decisions?
 We analyzed major power generation
technologies over 1988-2002 period
 Central generation needs new T&D, DG
needs 10% or less new T&D wires.
 Assumed 8% cost of capital for CG, 12%
for DG
 Determined retail price/kWh needed in
each year, given then current data.

Conclusion of Historical Study
 Electric monopolies limited choices to
central plants, ignoring cheaper and
cleaner distributed generation options
 IPP companies built DG under PURPA
rules, but shifted to central generation
with passage of EPACT
 Neither monopolies nor IPP’s built
projects to recycle industrial waste
energy
What is Optimum Future
Generation?
 We modeled 8 scenarios to meet EIA
projected US load growth through 2020
(43%)
 Found each technology’s capital cost,
performance, emissions for each year
 Added 100% T&D for central generation,
10% for DG
 Met load growth with 8 scenarios: all
central, all DG and blended scenarios

Why does the power industry
make suboptimal decisions?
 Many barriers to market competition, can be
likened to the layers of an onion
 The core of the ‘onion’ is the universal ban
on private wires.
 There can never be effective competition
when power cannot move except through
the monopolist distribution wires
 No polity in the world, to my knowledge,
allows private electric wires.
CAEM Mission (proposed)
Change the way the world makes
power by persuading governments
to remove all barriers to competitive
generation and delivery of power
and end monopoly protection of
electric distribution.
Expected Results


Increase availability of energy services

Lower capital cost

Reduce power costs
