3What is Clean Energy?
- Clean energy includes demand- and supply-side
resources that deliver clean, reliable, and
low-cost ways to meet energy demand and reduce
peak electricity system loads.
- Energy Efficiency reduces demand for energy and
peak electricity system loads. Common energy
efficiency measures include hundreds of
technologies and processes for practically all
end uses across all sectors of the economy. - Renewable Energy is partially or entirely
generated from non-fossil energy sources.
Renewable energy definitions vary by state, but
usually include solar, wind, geothermal, biomass,
biogas, and low-impact hydroelectric power. - Combined Heat Power, also known as
cogeneration, is a clean, efficient approach to
generating electric and thermal energy from a
single fuel source. Inherently an energy
efficiency measure.
4Clean Energy Benefits
- Clean energy can reduce electricity demand and
meet load growth to help address many state
energy challenges
Primary Clean Energy Benefits
Reduce energy demand
Meet load growth with fewer environmental consequences
State Energy Challenges
Electricity demand continues to rise
Electricity transmission systems are overburdened
Many base-load plants are aging
Volatile natural gas prices and financial risk as well as high energy prices
Reducing emissions to improve air quality and comply with clean air rules.
Additional Clean Energy Benefits
Reduced energy-related air emissions
Increased power reliability
Increased fuel diversity
Efficient use of natural resources
Increased state economic development
5Energy Portfolio Standards (EPS)
- Many states are creating Energy Portfolio
Standards (EPS) Renewable, Alternative Energy,
Energy Efficiency - Since FL is in initial discussion stages, I will
use EPS - Policy Objective EPS requirements create market
demand for clean energy supply by mandating that
utilities and electricity providers serve load
with a minimum requirement of clean energy. - Policy Advantages
- Due to market-based approach, has potential to
achieve policy objectives efficiently and at
relatively modest cost (ratepayer impacts
generally range from less than 1 increases to
0.5 savings). - Spreads compliance costs among all customers.
- Functions in both regulated and unregulated state
electricity markets. - Provides a clear and long-term target for clean
energy generation that can increase investors
and developers confidence in the prospects for
renewable energy.1
1. Provided the state sends strong signals that
this is a policy that will last.
6States With EPS Requirements
CHP/waste heat recovery eligible
7States With EPS Requirements (2)
States with EPS requirements mandate that between
1 251 of electricity be generated from
renewable sources by a specified date.
Note 1. Higher percentages are typically for
states that already have a relatively large
amount of RE, like NY, CA and ME Source Navigant

Renewable Energy (DSIRE) and California Energy
Commission.
8EPS Design
- States tailor EPS requirements to fit policy
objectives, electricity market conditions and
clean energy potential. - Key features of EPS design
- Goals and Objectives
- Applicability
- Eligibility
- Compliance
- Overall design of EPS requirements can influence
investor confidence, the ability of markets to
develop, and opportunities for project developers
and investors to recover capital investments.
9Key Features in EPS Design
Several best practices for EPS design features
have emerged based on state experiences.
Key features in EPS design
Accounting methods (e.g., energy production versus installed capacity requirements RECs or bundled energy only). Resource eligibility Time horizons for compliance periods Mandatory or voluntary participation Flexible compliance mechanisms to guard against high prices or the lack of supply of renewable energy Coordination with Federal and State energy policies Cost recovery mechanisms for utilities Enforcement mechanisms for non-compliance Incorporate technology tiers and/or credit multipliers to encourage particular technologies.
10Resource Eligibility
Eligibility of technologies varies by state and
depends on whether an energy resource or
technology supports state goals.
Renewable CHP systems are eligible
fossil-fueled CHP systems are not
eligible. Includes only those states that allow
fuel cells using nonrenewable energy sources of
hydrogen. Some states allow only renewable fuel
cells (Arizona, California, Colorado, Delaware,
Massachusetts, Maryland, New Mexico, New York,
Rhode Island, Wisconsin) as eligible
technologies. Source U.S. EPA Clean
Energy-Environment Guide to Action (2006),
Database of State Incentives for Renewable Energy
(DSIRE) last accessed July 2007,
11Resource Eligibility (2)
- EPS requirements should fit policy objectives,
electricity market conditions and clean energy
potential. - Important to complete a potential study
- Clearly understand implications of eligible
vintage resources - Increasingly, states are including non-renewable
energy in EPS (e.g. EE, CHP) - By including EE, North Carolina found the overall
cost of a RPS was reduced over the long-term - By including CHP, states promote the efficient
generation of electricity and thermal energy
12Incorporating CHP into EPS
- States are increasingly including CHP as an
eligible EPS resource. - Inclusion may require a minimum efficiency
requirement (e.g., 50 total efficiency in
Connecticut) or designation as a qualifying
facility under the Public Utilities Regulatory
Policy Act (such as in Maine ). - These efficiency requirements also usually
require some minimum threshold of recovered
electric and/or thermal energy, such as
Connecticuts 20 minimum thermal threshold. - EPS eligibility requirements may set emission
limits for emitting technologies. - Through 2005, California sources were required to
produce zero emissions or meet the 2007 state
emission limits for DG to qualify as eligible. - In Connecticut, emission limits apply to biomass
facilities.
13Incorporating CHP into EPS (2)
- CHP systems that are fueled with a qualifying
renewable resource are eligible under traditional
EPS. In this context, typically only the electric
output of the CHP system is eligible. States can
also include the thermal output for these systems
in EPS to fully value CHP benefits. - There are numerous states that credit thermal
output in their environmental regulations - California, Maine, Rhode Island, and Texas
include thermal output in their Small DG Rule. As
well as EPAs Combustion Turbine New Source
Performance Standards. - To account for the thermal output of CHP units,
convert the measured steam output (Btu) to an
equivalent electrical output (MWh) through a unit
conversion factor (1 MWh 3.413 MMBtu). By
adding the thermal and electric output together,
states are recognizing the full environmental and
emissions benefits of CHP. - EPS language can be modified to state that CHP
output will be calculated as the electric output
plus the thermal output in MW, based on the
conversion of 1 MWh 3.413 MMBtu of heat output.
14Incorporating EE into EPS
- Increasingly, states are setting EE goals
- Goals include of demand growth (TX, CA), of
supply (CT), of sales (HI) - Important to have clear EMV established
- Recent ACEEE report for FL assumed EE goal of
0.2 of electricity sales in 2009, an additional
0.4 in 2010 until savings of 1 per year are
being achieved. Gas sales 0.1 in year one, 0.2
in year two, increasing to 0.5 savings in year
five and thereafter. - Including EE as part of an ERS can reduce the
overall cost to achieve goals over the long term
(NC)
15Incorporating EE into EPS (2)
- CA, CO, CT, HI, IL, NV, NJ, PA, TX, VT
- Hawaii, Nevada, and Pennsylvania have indirect
EEPS as part of their RPS/AEPS. - Illinois's EEPS is a goal (not a requirement)
under the state's Sustainable Energy Plan. - Colorado EEPS is part of a utility/PUC settlement
agreement - Vermont EEPS is incorporated into statewide
contracts for energy efficiency. - As of 1/1/07. http//www.epa.gov/cleanenergy/state

North Carolina RPS Study Results
17Tiers and Multipliers
Credit Multipliers
- States regularly incorporate technology tiers
and/or vintage tiers and/or credit
multipliers to encourage particular
technologies. - By using tiers, different types of resources
arent competing for the same percentage. - Connecticut 3 tiers. Tier I and II are new
renewable generation and Tier III is EE, CHP and
DR. - Credit multipliers are an effective method of
placing increased value on a specific resource.
AZ 1.5 for in-state solar generation installed pre-2005 1.3 for renewables installed in 2001, 1.2 for 2002, 1.1 for 2003 in-state manufacturing and DG multipliers proposed rule would eliminate multipliers for projects installed after 2005
DE 3 for solar or fuel cells before 2014 1.5 for wind sited in DE before end of 2012
CO 1.25 for in-state renewable resources
NV 1.15 for distributed renewable generation 2.4 for PV (2.55 for DG PV) 0.7 for customer-sited reverse polymerization waste tire facilities
NM 2 for biomass, geothermal, LFG, or fuel cell 3 for solar
DC 1.2 for wind and solar through 2006 and 1.1 from 2007 to 2009 1.1 for methane gas through 2009
MD 1.2 for wind through 2005 and 1.1 for wind from 2006 to 2008 1.1 for landfill methane through 2008 2.0 for solar

18Scope of EPS (entities that must meet requirement)
- EPS requirements are most commonly applied to
investor-owned utilities and electric service
providers. - Unusual for mandatory EPS requirements to extend
to municipal utilities and cooperatives, as these
entities are predominately self-regulated. - Hawaii and Wisconsin require public utilities to
fully comply with RPS - Some states have created EPS provisions for
munis and coops - Colorado RPS includes municipal and cooperative
utilities, but they can opt-out or self-certify.
If they self-certify, compliance reports are for
informational purposes only. - Washington RPS passed by ballot initiative calls
for electric utilities that serve more than
25,000 customers in the state to obtain 15 of
their electricity from new renewables by 2020 and
to undertake cost-effective energy conservation.
19EPS Compliance
- Generally, there are two types
- Regulated markets
- Tend to use long-term bundled contracts for
electricity and RECs - Utility RFP solicitations or bilateral
negotiations with PUC oversight - Restructured markets
- Tend to use short-term RECs trade to multiple
parties, without PUC oversight - Developers often sell electricity and RECs
separately - NYSERDAs central procurement approach intended
to (in some degree) replicate regulated market
outcomes in a restructured environment
20Using RECs to Meet EPS Requirement
- EPS Compliance
- Generally three ways that affected entities may
comply with the EPS requirements - Own a renewable energy facility,
- Purchase Renewable Energy Certificates (RECs),
- Purchase electricity from a renewable facility
inclusive of all renewable attributes. - Clearly identifying accounting methods for the
EPS is critical (e.g., energy production versus
installed capacity requirements RECs or bundled
energy only).
21Using RECs to Meet EPS Requirement (2)
- Most states require affected entities to meet EPS
through surrender and retirement of RECs. - Increases flexibility and reduces compliance cost
- Can provide income to project developers
- Important to understand tradeoff of accepting
out-of-state RECs (reduce compliance cost) and
the development of in-state clean energy and
economic development. - Policymakers should have clear understanding of
available in-state resource potential
22Using RECs to Meet EPS Requirement (3)
- Most cases, formation of a REC amount of
electricity generated (and thermal if CHP
eligible) - EPS must have system of tracking the generation
in place to ensure it actually comes from
eligible resource. Many existing tracking systems
used to meet emissions disclosure requirements - Northeast NEPOOL GIS
- Mid-Atlantic PJM GATS
- West WREGIS
- TX ERCOT
23Penalties for Not Achieving EPS Requirement
- States have found having a credible
non-compliance mechanism in place in the form of
penalties is helpful however, states provide
flexibility in compliance. - Many states use alternative compliance payments
(ACP) which an affected entity can pay if they
are unable to procure the required amount of
clean energy. - If the affected entities cant purchase RECs
below the ACP price, they pay the state the ACP
as an alternative. - The state typically use these funds to promote
clean energy projects - ACP price typically escalates over time
24Elements of Successful Implementation
A number of best practices have emerged for
implementing effective EPS requirements based on
state experiences.
Elements of Successful Implementation
Develop broad support, including top-level support of the Governor and/or legislature and hold actionoriented facilitated discussions among key stakeholders. Determine mix and amount of clean energy desired. (Careful analysis and modeling of expected impacts prior to establishing target is key to success.) Establish a long timeline to encourage private investment. Establish cost caps on the price to comply with EPS requirements, high enough to encourage use of a range of eligible technologies but low enough to protect electricity suppliers. Make sure a credible non-compliance mechanism is in place in the form of penalties however, provide flexibility in compliance.
25Aligning Other Policies to Achieve EPS
- Ensuring other key policies are aligned with
promoting increased use of clean energy can
greatly increase the success of the EPS - Utility throughput-incentive
- Standby-rates
- Interconnection rules
- Output-based emission for DG
- Consider other policy options, such as a resource
loading order as in California
