ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 2/16 Small CV Marcel Didden 1998Master in electrical engineering, RWTH Aachen K.U.Leuven, Energy Institute DSM and IRP in a deregulated electricity market K.U.Leuven, Energy Institute Cost benefit analysis of voltage sag immunization methods

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 3/16 Outline 1. Introduction 2. Large customers without energy intensive process 3. Energy Performance Contracting 4. Conclusions and future perspective

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 4/16 1. Introduction Kyoto commitments in Europe High expectations for energy efficiency - High saving potential known (technical as well as economic) - Market barriers prevent the realization of this potential Governments should help to remove these barriers

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 5/16 1. Introduction Different approaches for different consumer-groups 1) Large consumers with energy intensive process 2) Large consumers without energy intensive process 3) Others: Small and Medium Enterprises, residentials Presentation: focus on 2)

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 6/16 Large consumers without energy intensive process Electricity: Huge savings potential 1) Motors (50% of overall electricity consumption) - Variable Speed Drives - High efficiency motors 2) Lighting (80% consumption in office environment) - 16 mm TL-lamps - Fittings 3) Process air 4) Cooling

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 7/16 Large consumers without energy intensive process Some market barriers in industry: - Short term awareness / Bounded rationality -Reluctancy to adopt new techniques -Split incentives -Disruption in routine -Limited investment capital

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 8/16 Large consumers without energy intensive process Approaches: 1) Giving general information 2) Energy audit 3) Outsourcing Company pays fix price for lighting or motors

Energy Performance Contracting 4) Energy Performance Contracting Third party installs, maintains and bares risk for installation and is only paid for by a part of the savings To good to be true? Some issues: a) stipulation / measurement of the savings b) initial investment c) general confidence in this type of contract

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 10/16 3. Energy Performance Contracting a) Stipulation of the savings General question: how to measure savings ? US: many argumentation about these savings - Influence of the weather (especially in heating contracts) - Influence of increase / decrease production

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 11/16 3. Energy Performance Contracting - Solution: measurement protocols for different retrofits - 4 different types of measurement in the International Performance Measurement and verification protocol. -Important: measurement costs are 1-10% of retrofit costs For example: Protocol A - If usage of application is constant or known in forehand - Only measurement of power before and after the retrofit - Measurement error to be expected: +/- 20%

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 12/16 3. Energy Performance Contracting b) Initial investment Small ESCO’s only get a high-risk loan at the bank Options: i) Guaranteed savings: - Company takes loan at the bank and ESCO gets part of the savings - Savings lower: ESCO pays company extra - Savings higher: surplus is divided

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 13/16 3. Energy Performance Contracting ii) Shared savings - ESCO takes loan at the bank, company pays % of savings Pay from savings - Almost the same as shared savings but the payments to the bank are proportional to the actual savings - Not often used since bank demands a very high intrest Guaranteed Savings (GS) vs Shared Savings (SS) - Most contracts in the US are GS - GS paybacks up to 5 years, SS up to 3 years

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 14/16 3. Energy Performance Contracting c) General confidence - ESCO’s in the US have bad name due to contracts in the past -Organization (US: National Association of ESCO’s or NAESCO) gives accreditation to reliable ESCO’s End goal: - Tender by company where accredited ESCO’s can apply - ESCO that proves the highest savings, is contracted

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 15/16 4. Conclusions -ESCO-market is a good method to overcome market barriers in large companies without energy intensive production process - Regulatory framework has to be set by the government to get a well functioning market: - measurement guidelines - accreditation

ENERGY INSTITUTE KATHOLIEKE UNIVERSITEIT LEUVEN 16/16 4. Future Perspective Deregulation: -ESCO-market is expected to grow in future -Also alliances with utilities who want to gain consumers Additional Information NAESCO: International Performance Measurement and verification protocol : IEA-DSM Agreement: dsm.iea.org  library  Task VI
