As Texans begin to recover from last month's once-in-a-century winter storm, many wonder how the state — an icon of the oil and gas industry and home to Houston, "the energy capital of the world" — was thrust into darkness for days on end.
When the Texas power grid began failing in communities statewide, many in positions of power quickly laid the blame at the feet of the renewables industry. But with solar and wind power accounting for only 28.6 percent of the state's energy supply, clearly, renewables were not the sole, or even primary, culprits responsible for the massive outages. The facts point to a much more complex set of circumstances — a series of extreme weather events, one after the other; a burgeoning population; and a grossly unprepared system — all of which combined to cause an increasingly strained, aging grid to fail spectacularly.
The events of last month were a not-so-subtle demonstration of the inadequacy of our current power structure, but what does that mean for the future of Texas energy? Obviously, Texas leaders and the Electric Reliability Council of Texas (ERCOT) must begin updating the state's grid with the resources necessary to sustain the rapidly increasing demand for reliable power. Undoubtedly, that will cause a hike in consumer energy costs, especially in deregulated markets like Houston, where profitability and demand drive prices.
Widespread distributed generation of solar energy—rather than the state's current emphasis on utility-scale solar generation — would provide a highly effective, long-term solution to minimizing strain on Texas' power grid. This means dramatically increasing the number of local solar installations on residential and commercial properties statewide. Think about it: The distance and infrastructure required to bring power from West Texas solar farms to the state's urban centers leaves too much room for vulnerabilities. Solar makes more sense on-site, behind the meter, and paired with storage for backup power.
Simply stated, the more businesses and residences who have solar power, the less burden on the grid and the more insulated the grid is against failure. Further, by installing batteries such as the Tesla Powerwall for backup power, solar customers control their own power supply and ensure its reliability, even during extreme weather events like the one we just experienced. These batteries are mass market-ready, reliable and cost-efficient today.
With the increasing volatility of the Texas energy market, home and business owners are finding solar is a more appealing investment than ever before.
The amount of solar power required to power a home or business depends on the amount of energy the owner seeks to offset. For example, a solar array geared toward reducing an energy bill will be significantly smaller than a system designed to take the customer off the grid entirely. Backup power solutions are similarly dependent, with options ranging from a single battery capable of powering small household appliances to a bank of several batteries or a generator able to power a whole household or commercial space. Either way, the combination of solar power and backup provides reliability many Texans wished they had during the record freeze we just endured.
The public outcry over the massive power outages has laid a mandate at the feet of state leaders: Do what is necessary to make the power grid sustainable. At the same time, utilities statewide are looking at what they can do to increase reliability in their own communities. Deregulated energy prices will only rise because of continuing population growth and the need to update grid infrastructure.
No matter how you look at it, enlarging the state's independent solar infrastructure is a reliable way to protect businesses and homeowners alike against surging energy costs and weather-related power outages.
