1 KINGDOM OF MOROCCO ENERGY EFFICIENCY STRATEGY AT THE NATIONAL OFFICE OF ELECTRICITY AND DRINKING WATER «ONEE» ALGIERS, ALGERIA DECEMBER 2013 MUSTAPHA HAJJI ONEE-IEA BS. MSC, MBA, Ph.DC

2 ECONOMIC CONTEXT & THE DRIVING FORCES FOR EE MOROCCO IS ENERGY DEPENDENT GLOBAL ENERGY DEMAND IS GROWING RAPIDLY, WITH SHIFTING DEMAND AND SUPPLY PATTERNS GROWING ECONOMY, URBANIZATION AND POPULATION THE CONTINUOUS RISING AND VOLATILITY OF OIL AND GAS PRICES ENVIRONMENTAL CONCERNS «CLIMATE CHANGE» ENERGY FUTURE UNCERTAINTIES SECTOR OF WW WATER AND WASTEWATER ARE INTRINSICALLY ENERGY INTENSIVE SCARE AND FAR RESOURCES DEEP AQUIFER DUE TO OVER EXPLOITATION AND FREQUENT DROUGHT SEASONS ENVIRONMENTAL CONCERNS WASTEWATER MANAGEMENT

3 Water services are monopolistic by nature (on a local level) and are not naturally driven to increase efficiency and achieve best practices

4 LEGAL AND INSTITUTIONAL FRAMEWORK LAW ON ENERGY EFFICIENCY ENERGY EFFICIENCY IS NOW CONSIDERED A FOURTH ENERGY AFTER FOSSIL FUELS, RENEWABLE ENERGY AND NUCLEAR ENERGY. THIS LAW AIMS TO INCREASE ENERGY EFFICIENCY IN THE USE OF ENERGY, AVOID WASTE, REDUCE THE BURDEN ENERGY COST ON THE NATIONAL ECONOMY AND CONTRIBUTE TO SUSTAINABLE DEVELOPMENT. AS DEFINED BY THE 1ST ARTICLE TROUGH :+ ENERGY EFFICIENCY ACTION PROGRAM ENERGY PERFORMANCE ENERGY AUDIT ESCOS ENERGY SERVICE COMPANY ENERGY IMPACT STUDIES PENALTIES FOR VIOLATION OF THE LAWS WAITING FOR ENFORCEMENT DECREE? INSTITUTIONS CREATION OF ADEREE MASEN

15 Facts Water sector is the largest consumer of electrical energy in Morocco (> 10 % of total energy consumption) High potential for energy reduction (estimation before project appraisal 20%) High potential in particular in the field of pumping stations, submersible pumps in well fields

16 STRATEGY FOR ENERGY EFFICIENCY THE ONEE WATER BRANCH CONFERS A GREAT IMPORTANCE TO THE COST OF ENERGY, THE RATIONALIZATION AND THE OPTIMIZATION OF THE ENERGY BILL. TO THIS END, SEVERAL ACTIONS ARE TAKEN AT DIFFERENT STAGES: NEW PROJECT: SYSTEM DESIGN PHASE : THE CHOICE OF THE OPTIMAL SOLUTION TAKING INTO ACCOUNT THE PROJECT LIFE CYCLE ( TECHNICAL AND ECONOMIC ALTERNATIVES ANALYSIS AND CHOICE OF ECONOMIC DIAMETER THAT MINIMIZES ENERGY COST) SETTING A MINIMUM PERFORMANCE REQUIREMENT FOR PUMPING UNITS AND USING VARIABLE SPEED PUMPS CHOICE OF DESALINATION SYSTEM WITH HIGH ENERGY PERFORMANCES AND ENERGY RECOVERY GIS DEM «HEAD MINIMIZING» REMOTE SENSING AND SCADA CONTRACTING PHASE HIGH ATTRIBUTION TO SYSTEM PERFORMANCE (PUMP STATION, TREATMENT PLANT.) REVIEW OF THE PROJECET ENERGY BALANCE SUBMITTED BY BIDDERS; OPTIMIZATION OF ELECTRICAL INSTALLATIONS ( INSTALLING COMPENSATING BATTERIES, INSTALLATION OF CENTRAL MEASURES, LIMITING THE VOLTAGE DROP SETTING THE STANDARDS OF ELECTRICAL INSTALLATIONS... ) ; OPTIMIZATION OF HYDRAULIC NETWORK FOR NONE REVENUE WATER

17 STRATEGY FOR ENERGY EFFICIENCY EXISTING FACILITIES: THE FOLLOWING ACTIONS ARE BEEN IMPLEMENTED AS A CONTINUOUS PROCESS: DATA VERIFICATION AND DOUBLE CHECKING OF INVOICES ISSUED BY ENERGY SUPPLIERS ( ONE -BRANCH ELECTRICITY BOARDS AND DEALERS ) ; CAPACITOR INSTALLATION AND MONITORING FOR ADEQUATE TUNING OF POWER FACTOR (PHI COSINE ) TO AVOID AS MUCH AS POSSIBLE THE CORRESPONDING PENALTIES AND ENERGY LOSS FOR THE ELECTRICITY PROVIDER ; COORDINATION WITH SUPPLIERS OF ELECTRICITY TO MINIMIZE POWER OUTAGES THAT NEGATIVELY INFLUENCE THE HYDRAULIC PERFORMANCE OF FACILITIES ONEE ELECTRICITY BRANCH; ANNUAL SEMINARS ARE ORGANIZED FOR EVALUATION AND PLANNING FOR THE FUTURE ACTIONS; MEASUREMENT CAMPAIGNS TO ASSESS PUMP PERFORMANCES WITH THE AIM OF MASTERING THE KWH/M3 RATIO ; IMPLEMENTATION OF ENERGY AUDITS OF SOME LARGE FACILITIES TO STREAMLINE AND OPTIMIZE THE COSTS OF ELECTRIC POWER; INCREASE WATER STORAGE RAW AND TREATED IN ORDER TO REDUCE PEAK PUMPING; ACQUIRE NEW EFFICIENT MOTORS FOR THE RENEWAL OF OBSOLETE OR LESS PERFORMING ONES WITHIN THE PERFORMANCE PROGRAM II. A BUDGET OF ABOUT 150 MILLION DIRHAMS IS ALLOCATED FOR THIS PURPOSE. O&M PROGRAM FOR WATER LOSS AND PRESSURE CONTROL INSTALLING SCADA SYSTEM FOR A REAL TIME MONITORING AND DATA ACQUISITION

18 PERFORMANCE CONTRACT A MANAGEMENT CONTRACT IS CONCLUDED EVERY YEAR BETWEEN THE ONEE HEADQUARTER AND THE REGIONAL DIRECTORATES. THE CONTRACT SETS THE PERFORMANCE TO OBTAIN PRIORITIES LOSS CONTROL «NRW» TRACKING AND REPORTING ENERGY PERFORMANCES BY RATIO MANAGEMENT «KwH/M3» STORAGE AUTONOMY Budget Central authorities RD PC

19 Management contact for energy use chapter Step 4: share your success and repeat «annual meetings» Step1establish a baseline for electricity use Act Plan Check Do Step 3 track and evaluate the improvements semi annual Step2: implement improvement projects

20 Current Actions for Optimizing Energy Use Central authorities provides: 1- Technical support and follow-up of their action plan : optimize energy consumption Analyze operating reports and energy costs, The control is operated on the 80% on the total incurred energy expenses of the 20% of the water facilities energy intensive 20
