Utilities and regulators evaluate grid modernization initiatives using economic paradigms. They determine if investments at the grid edge are cost effective relative to investments made in traditional generation, transmission and distribution assets. The Intergovernmental Panel on Climate Change (IPCC) recently published a special report titled ‘Global Warming of 1.5°C’, with an accompanying Summary for Policymakers. The Summary stated that if global warming continues at its current rate, we will likely reach a 1.5°C increase in global mean surface temperature (GMST) compared to pre-industrial levels between the years 2030 and 2052. The Report and Summary provided a comparison of outcomes we can expect if GMST increases to 1.5°C versus 2.0°C. It also presented solutions to support limiting global warming to the smaller value.  

Peak demand is the highest rate of electricity use. Fortunately, it only occurs a few times a year – usually on the hottest days of the year or on the very coldest days of the year, depending on your geography. Our power systems are prepared for these peaks (otherwise we risk potential blackouts), but as urban populations increase, and we add more variable renewable energy resources to our grid, we see more need to accommodate increases in peak demand. Traditionally, utilities would forecast demand in their service territories and resort to upgrading or building new peaking power plants to supply the anticipated increase in electricity demand. This solution tends to be land-intensive and has resulted in significant increases in greenhouse gas emissions.

I take the bus to work. On any given weekday, you can find me waiting on the side of a road while vehicles of all shapes and sizes whiz by, leaving behind a trail of noise and exhaust. It would be all well and good if this was just another weekday annoyance that could be easily shrugged off, like a fresh pile of snow blocking the sidewalk or a texter blissfully skipping the line at a busy coffee shop. But that’s not the case. Vehicle exhaust is a known pollutant that significantly affects human health and the environment. Regulators put limits on emissions – but these generally focus on new car sales, and then they can still be tampered with. So as a commuter waiting at the side of a busy road, I don’t feel too reassured. But, when I see that clean technology goals for electric vehicles are on track, hear announcements from companies like Tesla, Thor and Volvo electrifying trucking fleets, and read about commitments by governments to support these efforts, I do feel hopeful.
