“The smart grid” is a notoriously complex subject that is still quite abstract to many in the energy industry. Few know more about it than Silicon Valley-based boardroom consultant, author (of the bilingual English-Chinese “Smart Grid Dictionary”), and professional explainer Christine Hertzog. In this article she offers her insights on the major smart grids trends to be expected in the coming years. Her focus is on the U.S., but for European readers it is very instructive as well – and might even serve as an inspiration. Some of her major predictions: cities will redefine what being a smart city means; consumers will be increasingly lured by new business models, standards will see increasing global adoption, grid resiliency strategies will take priority for investors, low-voltage grids and microgrids will gain in importance.
There are a number of prognostications about 2014 Smart Grid trends and anticipated accomplishments. This article offers a longer and broader view out to 2020. That’s a milestone year for renewable portfolio standards (RPS) in twelve states including California, Colorado, Connecticut, Massachusetts, New Jersey, Pennsylvania and Washington.
How much can change in the six years leading to 2020? Think about how much changed from 2007 to 2013. In that six year timeframe, the costs of solar panels dropped from $3.40/watt to 80 cents/watt, and PV deployments in the USA increased from 735 MW to 7200 MW. Over 37 million smart meters were installed in the USA.
Cybersecurity went from an afterthought to a significant concern for utilities as cyberattacks climbed. Water utilities alone have experienced a 60% increase in attacks in this timeframe. The term “prius effect” defined how awareness of driving style influences energy consumption. That insight launched scores of companies that wanted to do the same for home energy consumption. Home energy management systems became mainstream offerings from national telecommunications providers instead of customized integrations from niche solution providers. Much can happen in six years’ time.
Here are ten predictions about Smart Grid and Smart Cities activity occurring by 2020. Five are featured this week, and the remaining five will be identified next week.
1) California hits and exceeds its RPS objective of 33% renewable sources of electricity by 2020 – the most ambitious of all states with this calendar deadline. Other states also meet their RPS objectives. Here’s the twist – a significant portion of solar deployment is attached to the distribution grid, not the transmission grid. The surge in privately-owned deployments occurs as innovative business services reduce expensive friction in planning, financing, and sourcing solar installations. These distributed generation (DG) deployments obviate the need for expensive transmission grid investments and focus utility money on the historically underinvested low voltage grid. The Smart Grid’s bi-directional flow of electricity takes a big leap forward.
2) Grid resiliency strategies take priority for investor-owned, municipal, and rural utilities. Grid resiliency combines Smart Grid and grid hardening initiatives – because a hardened grid characterized by centralized generation, long distance transmission and dumb distribution is still a brittle grid. Hardware and software investments have to prove their value in situational awareness by reducing service outages and/or accelerating service recoveries from natural and human-caused disasters. Governmental, commercial and residential interests build microgrids that are capable of delivering a limited degree of building self-sufficiency in energy. “Graceful degradation” becomes the new buzzword phrase.
3) As utilities consider grid hardening, cities redefine what being a smart city really means. Smart cities aren’t smart if their critical infrastructure relies on fragile transmission or distribution grids. Resiliency planning looms large for smaller municipalities and regional governmental agencies. Utility line workers and pipeline workers are recognized as first responders and utilities play larger roles in local and regional disaster response/recovery planning exercises – whether the disaster is catastrophic weather or the grid is the target of a cyber attack. Critical infrastructure like police, fire, and medical facilities as well as centers for refuge are retrofitted whenever possible with microgrid solutions for energy security.
4) Consumer intermediation threats abound for utilities. Some investor-owned utilities, pummeled by Wall Street, will belatedly discover the value of “owning” a relationship and retaining and growing lifetime consumer value as alternative service providers intermediate their formerly captive customers. The localization of energy goes mainstream. Small-scale generation of kilowatts and negawatts is commonly available with a number of suppliers and service providers offering commercial and then residential consumers options that intermediate the traditional utility/consumer relationships. Consumers will be lured by business models that offer unique financial justifications, ease of doing business, and even fun in the form of gamification of programs that encourage consumer interactions.
5) Standards that define how to integrate or grid-tie microgrids and other standalone generation and energy storage assets for bi-directional electricity flows to utility distribution grids are globally adopted. In the USA, momentum from the commercial business sector, which fuel building as microgrid and building self-sufficiency concepts into projects, motivates utilities and regulatory agencies into proactive stances on standards development initiatives – particularly around cybersecurity and interoperability of privately-owned microgrid management systems and standalone generation and energy storage assets with utility distribution management systems.
