Smart Grids and Sustainability I
Smart grids coordinate needs & capabilities of generators grid operator end users electricity market stakeholders
to operate all parts of the system maximizing efficiency minimising costs minimising environmental impacts maximising system reliability, resilience, stability

Smart Grids and Sustainability II
Smart grids are important for
addressing current concerns with existing electricity systems, e.g., aging infrastructure
addressing increasing peak demands
enabling clean and/or
low-carbon technologies,
e.g., renewables, electric cars

Smart Grids and Sustainability III
Smart grids can help deployment of new electricity infrastructure in
developing countries and emerging economies
rural areas
sparsely populated areas
small “remote” systems not connected to centralized electricity infrastructure
