What is Clean Energy?What 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. Clean energy resources include:

–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.

State Approaches to EncourageClean EnergyState Approaches to EncourageClean EnergyFive state approaches with significant potential to increase clean energy supply.

State Approaches to Encourage Clean Energy Supply

Renewable Portfolio Standard (RPS)

Establish requirements for electric utilities and other retail electric providers to serve a specified minimum percentage (or absolute amount) of customer load with eligible sources of renewable electricity.


Establish clear application processes and technical requirements that apply to utilities within the state which reduce uncertainty and prevent time delays that clean distributed generation systems can encounter in obtaining approval for grid connection.

Public Benefit Funds (PBF) for State Clean

Energy Programs

Are a pool of resources used by states to invest in clean energy supply projects and are typically created by levying a small fee on customers’ electricity rates.

Utility RatesElectric and natural gas rates, set by Public Utility Commissions, can be designed to support clean distributed generation projects and avoid unintended barriers, while also providing appropriate cost recovery for utility services on which consumers depend.

Output Based Environmental

Regulations (OBR)

Establish emissions limits per unit of productive energy output of a process (i.e., electricity, thermal energy, or shaft power), with the goal of encouraging the use of efficient fuel conversion (through CHP) and renewable energy as air pollution control measures.

Standard Interconnection Encourages Clean EnergyStandard Interconnection Encourages Clean Energy

• Policy Objective: Establish clear and uniform application processes and technical requirements for connecting distributed generation (DG) systems to the electrical grid.

• Policy Advantages: These rules are an important mechanism for improving the market condition for clean DG by: – Ensuring that the costs of interconnection are the same throughout

the state and are commensurate with the nature, size, and scope of the DG project.

– Helping DG project developers accurately predict the time and costs involved in the application process and the technical requirements for interconnection.

– Ensuring that the project interconnection meets the safety and reliability needs of both the energy end-user and the utility.

Key Features of Standard Interconnection Rules Key Features of Standard Interconnection Rules

Standard interconnection rules address the application process and specify technical requirements for interconnecting DG systems

Key design feature

Application Process

• Includes all phases of the application process• May specify: application forms, timelines, fees, dispute

resolution process, insurance requirements and interconnection agreements (contractual documents)

Technical Interconnection Requirements

• Includes technical protocols and standards that govern how generators must interconnect with the electrical grid

• Standard may conform to industry or national standards (such as IEEE 1547 and UL 1741)

• May specify: type of permissible technology and system size, electrical grid attributes at point of interconnect, and equipment and protocols required at point of interconnect

Elements of Successful ImplementationElements of Successful Implementation

A number of best practices have emerged for effective implementation of standard interconnect rules.

Elements of Successful Implementation• Utility regulatory Commission leadership!

• Work collaboratively with interested stakeholder to develop clear, concise interconnection rules that are applicable to all potential DG technologies.

• Consider using existing rules and models as templates, including the National Association of Regulatory Utility Commissioners1, MidAtlantic Distributed Resources Initiative2, and rules of other states (Oregon).

• Address all components of the interconnection process, including issues related to both the application process and technical requirements.

• Consider making the application process and related fees commensurate with generator size.

• Create a streamlined process for small and simpler systems that are certified compliant to IEEE 1547 and UL Standard 1741.

• Develop standards that cover the scope of the desired DG technologies, generator types, sizes, and distribution system types.

• After adopting a standard, monitor effectiveness and update as needed based on rule effectiveness.

Leading State ExamplesLeading State Examples

• The Oregon PUC is in the process of developing uniform interconnection technical standards, procedures and agreements. They began the process in 2006 with the MADRI model rule and have initiated a stakeholder process to move forward. Currently, a draft Standard Small Generator Rule is open for comment. There have been several key improvements to the MADRI model rule: "field certification", non-inverter based Level 2 fast tracking up to 2 MW, and an increase of Level 1 to up to 25 kW. See: http://www.puc.state.or.us/PUC/admin_rules/intercon.shtml

• New York was one of the first states to issue standard interconnection requirements for DG systems. Enacted in 1999, the initial requirements were limited to DG systems rated up to 300 kW connected to radial distribution systems. New York modified these interconnection requirements to include interconnection to radial and secondary network distribution systems for DG with capacities up to 2 MW. See: http://www.dps.state.ny.us/distgen.htm.

• In November 1999, the Texas Public Utility Commission adopted substantive rules that apply to interconnecting generation facilities up to 10 MW. This ruling applies to both radial and secondary network systems. The rules require that Texas utilities evaluate applications based on pre-specified screening criteria, including equipment size and the relative size of the DG system to feeder load. These rules are intended to streamline the interconnection process for applicants. Texas ’s interconnection standards can be found in the Distributed Generation Interconnection Manual, available at: http://www.puc.state.tx.us/electric/business/dg/dgmanual.pdf

Utility Rates and Clean Energy (1 of 2) Utility Rates and Clean Energy (1 of 2)

Utility Rate Issues Related to Clean Energy

Exit FeesExit (or stranded asset recovery) fees are charged by utilities to departing loads to recover the fixed costs of capital assets without shifting these cost to other customers.

Standby Rates

Distributed clean energy facilities usually need to have standby power accessible. Utilities assess these rates based on the costs of providing intermittent service (i.e., the capability to provide grid power when needed).

Buyback RatesUtilities often buyback electricity from distributed clean energy projects. The rate for the power can be a critical component of project economics.

Electric utilities may have rate structures that create barriers to the development of clean distributed generation.

Utility Rates and Clean Energy (2 of 2)Utility Rates and Clean Energy (2 of 2)

States are employing strategies to avoid undue barriers and reap the benefits of clean DG while providing utilities with appropriate cost recovery.

Rate Strategies to Encourage DG Clean Energy

Exit Fee ExemptionsSome states have adopted exit fee exemptions for existing loads that leave a utility’s distribution system that are replaced with clean DG. (e.g. IL, MA, NY)

Standby RatesSome states are exploring approaches to standby rates that may more accurately reflect utility cost of providing standby service. (e.g. OR, CA, NY)

Buyback RatesSome states have net-metering regulation that provide small generators a guaranteed purchase price for excess generation.

DecouplingStates are evaluating new rate designs to “decouple” utility profits from sales volume removing a utility disincentive to support DG.

Rate CalculationStates are attempting to ensure that rates accurately reflect the costs and benefits of clean DG.

Quantifying DG Benefits

States may wish to explore ways to ensure that the benefits of clean DG can accrue to the electricity grid.

Natural Gas Rates Some states have established favorable natural gas rates for CHP facilities. (e.g. CT, CA, NY)

Best practices have emerged based on state experiences.

Elements of Successful Design & Implementation• Ensure that state PUC commissioners and staff have current and accurate

information regarding the rate issues for clean DG and their potential benefits for the electric system.

• Open a PUC docket to explore actual costs and system benefits of onsite clean energy supply and appropriateness of related rates.

• Establish a working group of interested stakeholders to consider design issues and develop recommendations for revised rates.

• Identify if existing or pending Renewable/Energy Efficiency Portfolio Standards or other policies, which might be significant drivers to new onsite clean DG, generate a need for rate evaluations.

• Whenever new rates are adopted, monitor utility compliance, pace of new clean energy installations, and impact on rate payers.



• California and New York have established revised standby rate structures that ensure fair and reasonable treatment of clean DG. Other states have adopted exit fee exemptions for existing loads that leave a utility's distribution system. Illinois, Massachusetts, and New York allow certain levels of exemption from these fees for loads that are replaced by clean DG, specifically CHP and renewables.

• In 2004, the Oregon Public Utilities Commission approved a settlement regarding Portland General Electric Company’s tariffs for partial requirements customers. The load served by the on-site generation is treated in the same manner as any other load on the system, which under Oregon rules is obligated to have (or contract for) its share of contingency reserves. The on-site generation is, in effect, both contributing to and deriving benefits from the system’s overall reserve margin. Under the new rates, the partial requirements customer must pay or contract for contingency reserves equal to 7.0 percent (3.5 percent each for spinning and supplemental reserves) of the “reserve capacity” (i.e., either the nameplate capacity of the on-site unit or the amount of load it does not want to lose in case of an unscheduled outage; if the customer is able to shed load at the time its unit goes down, then it will be able to reduce the amount of contingency reserves it must carry). A similar pricing package has been adopted by PacifiCorp.

• Three states have established special gas rates for electric generators, including CHP projects. California has special gas tariffs for all electric generators. In 2003, the New York PSC ordered natural gas companies to create a rate class specifically for DG users and certify that they had removed rate-related barriers to DG. In 2005, the Connecticut Energy Independence Act included a provision that the natural gas delivery charges for customer-sited DG be waived and those costs recovered by the electric distribution company.

Utility Rates

Renewable Portfolio Standards (RPS) and Clean EnergyRenewable Portfolio Standards (RPS) and Clean Energy

• Policy Objective: RPS 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

States with RPS Requirements

States With RPS Requirements (1 of 2)States With RPS Requirements (1 of 2)

As of December 2006, RPS requirements have been established in 21 states plus the District of Columbia. Five of these states include CHP or waste heat recovery as an eligible resource..

Notes: In Minnesota the RPS is mandatory for the largest utility, Xcel, however, for the rest of the utilities and service providers it is a “good faith effort”. Under a separate agreement, and in addition to the RPS requirements, Xcel is required to build or contract for 125 MW of biomass electricity, and must build or contract for 1,125 MW of wind by 2010. In addition, Illinois has established a non-mandatory state goal for renewable energy. Arizona explicitly includes renewably fueled CHP systems

Key Features of RPS Design? (1 of 3)Key Features of RPS Design? (1 of 3)

States tailor RPS requirements to fit policy objectives, electricity market conditions and renewable potential.

Key features of effective RPS design

Goals and Objectives

To produce the best RPS design for the state, it is important to articulate goals and objectives early in the process that serve as a guide for design choices and avoid protracted rule implementation debate.

ApplicabilityRPS requirements are most commonly applied to investor-owned utilities and electric service providers. It is unusual for mandatory RPS requirements to extend to municipal utilities and cooperatives, as these entities are predominately self-regulated.

Eligibility

To support RPS goals, issues that states typically have considered include: What fuel sources and technologies are eligible? Do existing renewable sources count toward compliance? What geographic areas are eligible (e.g., generation within the state boundary or within a regional power pool)? Are central and customer-sited systems treated differently? (See Table on next slide.)

Compliance

Generally three ways that electricity suppliers may comply with the RPS requirements;

1) Own a renewable energy facility,

2) Purchase Renewable Energy Certificates,

3) Purchase electricity from a renewable facility inclusive of all renewable attributes.

The overall design of RPS requirements can influence investor confidence, the ability of markets to develop, and opportunities for project developers and investors to recover capital investments.

Eligibility of technologies varies by state and depends on whether an energy resource or technology supports state goals.


Key features in RPS design• Accounting methods (e.g., energy production versus installed

capacity requirements; RECs or bundled energy only).

• 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.

Several best practices for RPS design features have emerged based on state experiences.



A number of best practices have emerged for implementing effective RPS requirements based on state experiences.

Elements of Successful Implementation• Develop broad support, including top-level support of the

Governor and/or legislature and hold action –oriented 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 RPS 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.


• The legislation for California’s RPS requirements was enacted in September 2002. California’s RPS requirements originally required retail sellers of electricity to purchase 20% renewable electricity by 2017. Because of perceived significant IOU progress towards this goal, California accelerated this goal of 20% renewables to 2010 and set the state's 2020 goal at 33%. Retail sellers of electricity are required to increase their procurement of eligible renewable-energy resources by at least 2% per year, so that 20% of their retail sales are procured from eligible renewable energy resources by 2010. http://www.energy.ca.gov/portfolio/index.html

• The Connecticut RPS was originally promulgated in 1998 and took effect July 1, 2000, establishing requirements for two classes of renewable generating resources. In June 2005, Connecticut passed “An Act Concerning Energy Independence,” establishing a new RPS Class III that must be fulfilled with CHP and electricity savings from Conservation and Load Management programs. The new standard will require electric suppliers and distribution companies to obtain 1% of their generation from Class III resources beginning in 2007 and increasing by 1% per year until leveling out at 4% in 2010 and thereafter. The total RPS requirement started at 4% in 2004 and will rise to and remain at 14% in 2010 and thereafter (including the new Class III). http://www.cga.ct.gov/2005/ACT/PA/2005PA-00001-R00HB-07501SS1-PA.htm.
