4th International Wind Energy Summit 2019 • Marriot Hotel, Karachi • Development & Challenges of Renewable Energy • Towards Renewable Energy Dominance • Mayura Botejue • Renewable Energy Specialist • August 30, 2019
Renewed Debate on Role of Renewable Energy (RE) • Power Division Secretary Remarks • RE related technologies advancing & cost declining • Harnessing RE resources to the maximum for: • - Attaining energy security with RE contribution 30% by 2030 • - Decrease impact of thermal generation on environment • Benefits of visionary RE policy: • - Technological advancement • - Increased local investment in infrastructure • - Dispersed project development activity • - Skilled job creation • - Alignment with globally expressed climate change concerns
Pakistan - Abundant RE Resources • Maximized RE contribution via: • Utility scale projects • N-S & E-W (south) HV transmission links • Distributed generation through hybrid plants (wind, solar, hydro + storage) • Mini, micro grids (grid tied or isolated) • Net-metered roof top solar + storage • Biomass Hydro (North) Potential > 30 GW Solar Wind Potential > 1,000 GW Potential > 40 GW Ka-La = 1,200 KM Ka-Gw = 600 KM
RE Dominance - Long Way to Go Wind & Solar < 5% Dawn - 23 Aug 2019 https://www.dawn.com/news/1501131/energy-future-hinges-on-renewables
Barriers to Rapid RE Development • Institutional resistance • - Lack of familiarity • - Conventional mind set (concern on “unregulated” power) • - Era of advanced “disruptive” technologies • - Regulatory impediments • - Development pitfalls • Outdated analytical tools & inputs • - Era of intermittent power • - Impact of; • Distributed generation • Storage • DSM, smart meters & variable tariff • Land issue • - Zoning is key! Who lobbies for wind & solar?
RE Infrastructure Development Conventional Approach Outdated • Large capacity plants vs distributed generation • Raising capital - Institutional funding vs private capital • Skill sets of technocracy outdated - must adapt to master impact of advanced RE technologies • Conventional plants - long gestation period, delays & cost over runs • RE plants - fast track • Emergence of “Prosumers” • Institutional inertia Prosumer = Producer/Consumer (Net metered solar with battery storage)
Facilitating RE Dominance • Change essential - era of rapid technological advances: • Distributed generation • Grid unbundling • State institutions role: Forecaster, planner, regulator and technical standards enforcer • Private sector driven development (plant and infrastructure) • Development agency funds solicited for; • Resource mapping, GIS& resource assessments • Policy formulation • Training professional cadre on RE technologies
RE Dominance - Commercial & Technical Influences • Commercial • Electricity viewed as a commodity (buy/sell) • Wheeling of “green” power to businesses • Demand charge, time of day tariff & off grid option • Technical • Advanced forecasting of wind, solar & hydro energy yield • Net-metered roof top solar PV with battery storage (residential, commercial, industrial prosumers) - smart meters & DSM programs • Emergence of mini/micro grids • Run of river hydro with ‘pondage’ for regulation • Utility scale battery storage
Investment Climate & Regulations • State must declare intent: • - Goal of rapid expansion of RE capacity • IEEs conducted at zoned lands • No fatal flaws or citizen resistance • Tariff • FIT • Reverse auction (current trend) • Private sector investment • - Essential to increase rate of development • - Meet investor expectations (domestic & foreign) • - Address investor risk concerns (multiple)
RE Development Potential • ‘Hybridization’ of existing wind power plants in Sindh - solar &battery storage (fast track) • Further expansion of wind in Sindh (with solar + battery storage) • Run of river hydro (fast track & multiple) • Harnessing large scale wind & solar in Balochistan • Networked regional grids (wind, solar, hydro hybrids) • Isolated micro grids (biomass, solar + battery storage) • Net metered solar PV with storage (industrial, commercial & residential prosumers) • Offshore wind
Expansion of RE in Sindh • Wind in NE direction along Gharo corridor • - Large capacity WTGs (>3MW, net CF > 40%) • Solar &battery storage in hybrid arrangement • In SW direction on intertidal zone • Offshore wind Gharo wind corridor
Hybrid Power - Wind, Solar & Storage Suitable at operational wind projects • Power evacuated through existing substation • Analysis to optimize solar & battery capacities (resource & financial): • Wind (MW) • Solar (MW) • Battery (MWh) • Transformer (MVA) Maximize energy output through existing substation economically
Wind Power • Gharo Intertidal Zone • Close to Karachi • Land available • Major civil engineering challenge • Operational wind projects in Gharo
Wind, Solar & Hydro in Hybrid Mini Grid • Wind on ridge line, corridor • Solar in valley or rooftop • Battery storage • Hydro (pondage, regulation, pumped)
Harnessing large scale wind & solar in Balochistan • Wind plant • Solar PV &CSP plant • HVDC link to major N-S transmission artery • Battery storage (ramp rate control for intermittency) • Gas turbines & diesel for regulation (south) • Hydropower for regulation (north) Solar Wind Larger project capacity = Economics of scale
Smart Grid in the Prosumer Environment • DSM • Time of day tariff • Producing/consuming • Wheeling * Prosumer Fixed output No regulation Regulation Seasonal shortfall Phasing out Storage * Regulation Ancillary services *
Residential Prosumer • Building operating as a micro utility (networked or isolated) • Demand charge & time day tariff regime • Smart, integrated &network centric Not suitable in urban environment
Challenge of Distributed Generation Adv. Forecasting Networked Smart DSM Storage Australia Energy Market Operator
Isolated micro grids (solar + battery storage) • Solar & battery storage micro grids to serve rural sector • - Solar at individual houses if widely scattered • T&D losses eliminated • Carbon footprint reduced Pakistan: 60% rural population How many ‘off grid’? Solar & Storage Micro Grid in Tanzania
