RULE §25.181Energy Efficiency Goal

  (30) Industrial customer--A for-profit entity engaged in an industrial process taking electric service at transmission voltage, or a for-profit entity engaged in an industrial process taking electric service at distribution voltage that qualifies for a tax exemption under Tax Code §151.317 and has submitted an identification notice under subsection (u) of this section.

  (31) Inspection--Examination of a project to verify that an energy efficiency measure has been installed, is capable of performing its intended function, and is producing an energy savings or demand reduction equivalent to the energy savings or demand reduction reported towards meeting the energy efficiency goals of this section.

  (32) Installation rate--The percentage of measures that receive incentives under an energy efficiency program that are actually installed in a defined period of time. The installation rate is calculated by dividing the number of measures installed by the number of measures that receive incentives under an efficiency program in a defined period of time.

  (33) International performance measurement and verification protocol (IPMVP)--A guidance document issued by the Efficiency Valuation Organization with a framework and definitions describing the M&V approaches.

  (34) Lifetime energy (demand) savings--The energy (demand) savings over the lifetime of an installed measure(s), project(s), or program(s). May include consideration of measure estimated useful life, technical degradation, and other factors. Can be gross or net savings.

  (35) Load control--Activities that place the operation of electricity-consuming equipment under the control or dispatch of an energy efficiency service provider, an independent system operator, or other transmission organization or that are controlled by the customer, with the objective of producing energy or demand savings.

  (36) Load management--Load control activities that result in a reduction in peak demand, or a shifting of energy usage from a peak to an off-peak period or from high-price periods to lower price periods.

  (37) Market transformation program--Strategic programs intended to induce lasting structural or behavioral changes in the market that result in increased adoption of energy efficient technologies, services, and practices, as described in this section.

  (38) Measurement and verification--A subset of program impact evaluation that is associated with the documentation of energy or demand savings at individual sites or projects using one or more methods that can involve measurements, engineering calculations, statistical analyses, and/or computer simulation modeling. M&V approaches are defined in the IPMVP.

  (39) Net savings--The total change in load that is attributable to an energy efficiency program. This change in energy and/or demand use shall include, implicitly or explicitly, consideration of appropriate factors. These factors may include free ridership, participant and non-participant spillover, induced market effects, changes in the level of energy service, and/or other non-program causes of changes in energy use and/or demand.

  (40) Net-to-gross--A factor representing net program savings divided by gross program savings that is applied to gross program impacts to convert them into net program impacts. The factor may be made up of a variety of factors that create differences between gross and net savings, commonly considering the effects of free riders and spillover.

  (41) Non-participant spillover--Energy savings that occur when a program non-participant installs energy efficiency measures or applies energy savings practices as a result of a program's influence.

  (42) Off-peak period--Period during which the demand on an electric utility system is not at or near its maximum. For the purpose of this section, the off-peak period includes all hours that are not in the peak period.

  (43) Participant spillover--The additional energy savings that occur when a program participant independently installs incremental energy efficiency measures or applies energy savings practices after having participated in the efficiency program as a result of the program's influence.

  (44) Peak demand--Electrical demand at the times of highest annual demand on the utility's system at the source. Peak demand refers to Texas retail peak demand and, therefore, does not include demand of retail customers in other states or wholesale customers.

  (45) Peak demand reduction--Reduction in demand on the utility's system at the times of the utility's summer peak period or winter peak period.

  (46) Peak period--For the purpose of this section, the peak period consists of the hours from one p.m. to seven p.m. during the months of June, July, August, and September, and the hours of six a.m. to ten a.m. and six p.m. to ten p.m. during the months of December, January, and February, excluding weekends and Federal holidays.

  (47) Program year--A year in which an energy efficiency incentive program is implemented, beginning January 1 and ending December 31.

  (48) Projected savings--Values reported by an electric utility prior to the time the energy efficiency activities are implemented. Are typically estimates of savings prepared for program and/or portfolio design or planning purposes. These values are based on pre-program or portfolio estimates of factors such as per-unit savings values, operating hours, installation rates, and savings persistence rates. These values may utilize results of prior evaluations and/or values in the Technical Reference Manual. Can be indicated as first year, annual demand or energy savings, and/or lifetime energy or demand savings values. Can be indicated as gross savings and/or net savings values.

  (49) Renewable demand side management (DSM) technologies--Equipment that uses a renewable energy resource (renewable resource), as defined in §25.173(c) of this title (relating to Goal for Renewable Energy), a geothermal heat pump, a solar water heater, or another natural mechanism of the environment, that when installed at a customer site, reduces the customer's net purchases of energy, demand, or both.

  (50) Savings-to-Investment Ratio (SIR)--The ratio of the present value of a customer's estimated lifetime electricity cost savings from energy efficiency measures to the present value of the installation costs, inclusive of any incidental repairs, of those energy efficiency measures.

  (51) Self-delivered program--A program developed by a utility in an area in which customer choice is not offered that provides incentives directly to customers. The utility may use internal or external resources to design and administer the program.

  (52) Spillover--Reductions in energy consumption and/or demand caused by the presence of an energy efficiency program, beyond the program-related gross savings of the participants and without financial or technical assistance from the program. There can be participant and/or non-participant spillover.

  (53) Spillover rate--Estimate of energy savings attributable to spillover expressed as a percent of savings installed by participants through an energy efficiency program.

  (54) Standard offer contract--A contract between an energy efficiency service provider and a participating utility or between a participating utility and a commercial customer specifying standard payments based upon the amount of energy and peak demand savings achieved through energy efficiency measures, the measurement and verification protocols, and other terms and conditions, consistent with this section.

  (55) Standard offer program--A program under which a utility administers standard offer contracts between the utility and energy efficiency service providers.

  (56) Technical reference manual (TRM)--A resource document compiled by the commission's EM&V contractor that includes information used in program planning and reporting of energy efficiency programs. It can include savings values for measures, engineering algorithms to calculate savings, impact factors to be applied to calculated savings (e.g., net-to-gross values), protocols, source documentation, specified assumptions, and other relevant material to support the calculation of measure and program savings.

  (57) Verification--An independent assessment that a program has been implemented in accordance with the program design. The objectives of measure installation verification are to confirm the installation rate, that the installation meets reasonable quality standards, and that the measures are operating correctly and have the potential to generate the predicted savings. Verification activities are generally conducted during on-site surveys of a sample of projects. Project site inspections, participant phone and mail surveys and/or implementer and participant documentation review are typical activities associated with verification. Verification is also a subset of evaluation.
