Energy service company - Wikipedia, the free encyclopedia. An energy service company or energy savings company (ESCO or ESCo) is a commercial or non- profit business providing a broad range of energy solutions including designs and implementation of energy savings projects, retrofitting, energy conservation, energy infrastructure outsourcing, power generation and energy supply, and risk management. A newer breed of ESCO evolving in the UK now focuses more on innovative financing methods. These include off- balance sheet vehicles which own a range of applicable equipment configured in such a way as to reduce the energy cost of a building. 12/2/09 1 eere.energy.gov DOE-FEMP Super ESPC Process Flowcharts 12/01/09 eere.energy.gov Phase 1: Project Planning Assemble acquisition team Notify DOE COR of intent to respond ESCO Joint Effort Agency FFS & agency get.The building occupants, or landlord, then benefit from the energy savings and pay a fee to the ESCO SPV in return. At all times, the saving is guaranteed to exceed the fee. The ESCO starts by performing an analysis of the property, designs an energy efficient solution, installs the required elements, and maintains the system to ensure energy savings during the payback period. If the project does not provide returns on the investment, the ESCO is often responsible to pay the difference. One of the earliest examples was a company in Texas, Time Energy, which introduced a device to automate the switching of lights and other equipment to regulate energy use. The primary reason that the product did not initially sell was because potential users doubted that the savings would actually materialize. To combat this doubt, the company decided to install the device upfront and ask for a percentage of the savings that was accumulated. This report presents the results of Level 2 of a three-tiered evaluation of the U.S. Department of Energy Federal Energy Management Program's Super Energy Savings Performance Contract (Super ESPC) Program.

The result was the basis for the ESCO model. Through this process, the company achieved higher sales and more return since the savings were large. The first wave of ESCOs were often small divisions of large energy companies or small, upstart, independent companies. However, after the energy crisis came to an end, the companies had little leverage on potential clients to perform energy- saving projects, given the lower cost of energy. This prevented the growth experienced in the late 1. The industry grew slowly through the 1. HEC Inc., later renamed Select Energy Services, was acquired in 1. Northeast Utilities, and sold in 2. Ameresco. The term ESCO has also become more widely known among potential clients looking to upgrade their building systems that are either outdated and need to be replaced, or for campus and district energy plant upgrades. With deregulation in the U. S. Utilities, which for decades enjoyed the shelter of monopolies with guaranteed returns on power plant investments, now had to compete to supply power to many of their largest customers. They now looked to energy services as a potential new business line to retain their existing large customers. Also, with the new opportunities on the supply side, many energy services companies (ESCOs) started to expand into the generation market, building district power plants or including cogeneration facilities within efficiency projects. In 1. 99. 8, BGA entered the District Energy Plant business, completing construction on the first 3rd- party owned and operated district cooling plant in Florida. There was a significant consolidation among the remaining independent firms. According to the industry group NAESCO, revenues of ESCOs in the U. S. Other possible services provided include energy infrastructure outsourcing, energy supply, financing and risk management. It is this comprehensiveness of services that differentiates an ESCO from a common energy company, whose main business is solely providing energy to its customers. Typically compensation to the ESCO is performance based so that the benefits of improved energy efficiency are shared between the client and the ESCO. ESCOs often use performance contracting, meaning that if the project does not provide returns on the investment, the ESCO is responsible to pay the difference, thus assuring their clients of the energy and cost savings. Therefore, ESCOs are fundamentally different from consulting engineers and equipment contractors: the former are typically paid for their advice, whereas the latter are paid for the equipment, and neither accept any project risk. The risk- free nature of the service the ESCOs provide offers a convincing incentive for their clients to invest. Some have large parent companies, which allows them to self- finance projects. However, all ESCOs rely to some extent on third- party financing. Developing a project. This task is usually the responsibility of the ESCO. The ESCO often approaches a potential client with a proposal of an energy savings project and a performance contract. This ESCO is said to . Once the owner is aware of the possibility of an energy savings project, he or she may chose to place it out for bid, or just stick with the original ESCO. During the initial period of research and investigation, an energy auditor from the ESCO surveys the site and reviews the project's systems to determine areas where cost savings are feasible, usually free of charge to the client. This is the energy audit, and the phase is often referred to as the feasibility study. A hypothesis of the potential project is developed by the client and the auditor, and then the ESCO. The engineers are responsible for creating cost- effective measures to obtain the highest potential of energy savings. Following the completion of this phase, the monitoring and maintenance or Measurement and Verification (M & V) phase begins. This phase is the verification of the pre- construction calculations and is used to determine the actual cost savings. This phase is not always included in the performance contract. In fact, there are three options the owner must consider during the performance contract review. The client pays the ESCO its regular energy cost (or a large fraction of it), but the energy savings enable the ESCO to pay only a fraction of that to their energy supplier. The difference goes to pay the interest on the loan and to profit. Typically, ESCs are able to implement and finance the efficiency improvements better than their client company could by itself. Choosing an ESCO. This is usually the case when the client has developed the project on his or her own or is required to allow others to bid on the work as required by the government. The latter is the case on any state or federally funded project. The typical process includes a Request for Qualification (RFQ) in which the interested ESCO. Once received, the client creates a . This list is of the companies whose profile for the project best matches with the owners. The client then asks for a Request for Proposal (RFP) that is a much more detailed explanation of the project. This document contains all cost savings measures, products, M & V plans, and the performance contract. The client often allows a minimum of six weeks to compile the information before having it submitted. Once submitted, the Proposals are then reviewed by the client, who may conduct interviews with the applicants. The client then selects the ESCO that presents the best possible solution to the energy project, as determined by the client. A good ESCO will help the owner put all the pieces together from start to finish. According to the Energy Services Coalition. A common way to calculate energy savings is to measure the flows of energy associated with the ECM, and then to apply spreadsheet calculations to determine savings. For example, a chiller retrofit would require measurements of chilled water supply and return temperatures and k. W. The benefit of this approach is that the ECM is isolated, and that only energy flows associated with the ECM itself are considered. This method is described as Option A or Option B in the International Performance Measurement and Verification Protocol (IPMVP). Option A requires some measurement and allows for estimations of some parameters. Option B requires measurement of all parameters. In both options, calculations are done (typically in spreadsheets) to determine what energy savings. Option C uses utility bills to determine energy savings. There are many situations where Option A or Option B (Metering and Calculating) is the best approach to measuring energy savings, however, some ESCOs insist upon only using Option A or Option B, when clearly Option C would be most appropriate. If the ESCO was a lighting contractor, then Option A should work in all cases. Spot measurements of fixtures before and after, agreed upon hours of operation, and simple calculations can be inserted into a spreadsheet that can calculate savings. The same spreadsheet can be used over and over. However, for ESCOs that offer a variety of different retrofits, it is necessary to be able to employ all options so that the best option can be selected for each individual job. Controls Retrofits, or retrofits to HVAC systems are typically excellent candidates for Option C. This process, termed Measurement and Verification (M& V), is frequently performed by the ESCO, but may also be performed by the customer or a third party. The International Performance Measurement and Verification Protocol (IPMVP) is the standard M& V guideline for determining actual savings created by an energy management program. Because savings are the absence of energy use, they cannot be directly measured. IPMVP provides 4 methods for using measurement to reliably determine actual savings. A plan for applying the most appropriate of the 4 general methods to a specific project is typically created and agreed upon by all parties before implementation of the ECMs. IPMVP Option A . Parameters not selected for field measurement are estimated. IPMVP Option B . The simulation model must be calibrated so that it predicts an energy pattern that approximately matches actual metered data. Table 1 provides suggested IPMVP options for different project characteristics. For each project, an M& V approach which balances the uncertainty in achieved savings and the cost of the M& V plan should be selected.
