Diesel gensets

!  Hybrid Control ensures stable grid provided by the gensets

!  The solar grid inverters only follow the grid

!  Control/ measurement of total load

!  Regulation of inverter power - Power Management (PM) - to ensure stable and safe operation of minimum 1 genset

!  Genset Spinning Reserve, ensuring enough genset capacity available

!  Reverse Power Control, protection of gensets

!  Remote Emergency Control, immediate zero-power mode of inverters

Hybrid Control

PV plant integrated in diesel grid of luxury hotel

!  Luxury hotel in the Atacama Desert, Chile

!  Island system supplied by 3 diesel generators

!  ~ US$ 100,000 annual diesel costs

!  Diesel price of 0.85 US$ per liter

!  Project phase 1: 23 kWp PV plant

!  Feed into diesel grid

!  Hybrid controller ensures co-generation

!  Commissioned: June 2013

Case study

Solar power reduces diesel consumption

Case study

!  Load profile measurements during project planning

!  System solution: integration of PV in diesel grid, min of 1 genset must run continuously

!  Diesel savings of ~15% p.a.

!  Investment payback in 3 years

!  Project phase 2 (2017): 156kWp PV / 317kWh Li-Ion battery diesel hybrid system, diesel savings of ~65% p.a.

Huge potential for PV-diesel hybrid systems in offgrid agriculture and tourism in Egypt

Agriculture and tourism can become drivers of transition to solar power

Solar energy for self-consumption pays off - depending on fossil fuel subsidies, FX rate and capital cost

Comparison of energy costs in Egypt

Industrial energy costs

on-grid

Energy from diesel

generators1)

Energy from photovoltaic

plants2)

1)  Only diesel costs considered: 2.75 EGP/Liter

2)  LCOE method, all costs considered over 25 years lifetime: CAPEX, M&O, capital costs

Stable

Implementing solar energy in a business…

!  can sink operating expenses

!  increases planning dependability

!  creates greater independence

!  protects the environment as-is

w/o subsidies

Market barriers for PV-diesel hybrid solutions in Egypt

Diesel subsidies Time schedule of phase out is uncertain

Finance Unaccustomed cash flows, short investment horizon, weak EGP, high interest rate

Expertise More complex than solar home systems

Awareness / trust Local investors, farms, hotels, banks lack know-how and experience

Barriers need to be tackled in order to make solar PV successful

Agenda

!  Market development for PV-diesel hybrid solutions in Egypt

!  Increase awareness on reliability and cost-efficiency of PV-diesel hybrid solutions

!  Target group: local investors and financiers such as farms, hotels, commercial banks, leasing companies, funds
