■ What is the prospect for lower electricity prices? US electricity prices have steadily increased in nominal terms over the last five decades. However, using history as a guide, we observe two distinct periods of falling prices driven by technology and government subsidies. We believe that a confluence of factors could once again result in structurally lower prices.
■ Factors at play – Cheaper natural gas, the falling cost of photovoltaic solar systems, and the emergence of battery storage have the potential to drive down retail electricity prices. Transmission and distribution expenditure is often cited as a key driver of higher electricity prices, but our research forecasts a relatively minimal contribution of these expenditures to the real electricity price through 2040.
■ Potential impact to power market participants – In discussing implications for power market participants under a declining electricity price scenario, we posit: 1) consumers and utility-scale renewable energy generators would benefit; 2) wires-only utilities would see a mixed/neutral impact; and 3) vertically integrated utilities and retail/commercial scale renewable energy generators would be challenged.
■ A closer look at SolarCity – As a proxy for the US rooftop solar market, we consider SolarCity’s business model with a particular focus on the annual price escalator included in customer contracts. If electricity prices fall, our analysis suggests that renewal rate assumptions may prove aggressive – a risk to the company’s valuation.
