Hedging Against Natural Gas Price Volatility with Energy Storage

After a decade of low and relatively stable natural gas prices, should businesses bet on the trend continuing?

In a recent report entitled, “Wholesale electricity prices trended higher in 2021 due to increasing natural gas prices,” the United States Energy Information Association (EIA) puts into black and white what electricity, natural gas utilities, and commercial and industrial (C&I) energy consumers witnessed  over the last year: natural gas prices, which play an increasingly significant role in electricity prices, grew increasingly volatile – and expensive. According to the report, “Natural gas prices have remained relatively low in recent years; the cost of natural gas delivered to electric generators averaged $2.40 per million British thermal units (MMBtu) in 2020. However, natural gas prices trended higher over the last year. The delivered cost of natural gas to electricity generators grew from $3.19/MMBtu in January 2021 to an estimated $5.04/MMBtu in the fourth quarter of 2021.”

That’s a year-over-year increase of more than 30% from 2020 to 2021, and nearly a 60% in-year jump over the course of 2021. For all energy consumers, those are painful spikes. For energy-intensive industries, they pose an existential threat.

National benchmarks for natural gas prices have eased off their Q4 highs at the start of the year, but the market dynamics driving high and volatile natural gas prices remain in force: high global demand for natural gas, increasing use of natural gas as a bridge fuel to renewables adoption, and no significant increase in rig counts.

C&I energy users in the U.S. and Canada are just one extreme weather event away from dramatic price spikes. A cold wave in Texas last February sent spot prices up to $1000 per MMBtu – 250 times higher than normal – and had a comparable impact on electricity prices.

This winter the regional benchmark for gas prices in New England – Algonquin Citygate – has seen daily spot prices above $20 ten times so far, exceeding $30 over the weekend. Those costs are not passed to residential and some business customers immediately due to fixed tariffs but will inevitably flow through – businesses over the border in Connecticut saw their Eversource electric bills jump 30% compared a year previously, mostly due to their utility paying more for natural gas.

One key takeaway: it’s time for a fresh look at energy storage. Utility- and industrial-scale batteries can be part of a winning decarbonization and resiliency strategy that helps organizations take charge of their energy budgets and carbon footprint.

Energy Storage: A Single Solution for Many Pain Points

Natural gas is a valuable stop gap. It is cleaner burning than coal but still a fossil fuel. Getting to net zero carbon emissions by 2030, 2040, or 2050, the pledged end state of many major utilities and large energy users, is going to take a lot more than a less bad fossil fuel. And it doesn’t help that that option is no longer inexpensive.

Battery storage, whether at utility substations or on-site businesses, is growing in popularity because it makes a positive impact across energy costs, resilience, and sustainability. And when paired with solar, the impact can be even more transformative. Below are some of the key benefits of energy storage:

  1. Flexibility. Because they can be charged and discharged at the user’s discretion, they have proven to be very versatile. If a battery is connected to a solar array, the power in the battery is 100% renewable, meaning that whenever it is discharged, the resulting power use is clean energy. Less obvious, a battery can take its charge from the grid when the grid is operating most sustainably, i.e., a time when the grid is running on, or generating the most, renewable power.
  2. Cost Reduction. A charged battery is a powerful weapon in the energy budget battle. It can be discharged at times of peak demand, avoiding high-priced electricity (whether wholesale or time-of-use rate) AND reducing demand charges that impact overall rates.
  3. Resiliency. Energy storage or solar-plus-storage solutions can provide a reliable, always-on resource during blackouts or brownouts. As extreme weather events become more frequent, threatening transmission and distribution lines, energy storage solutions are being embraced by the C&I sector not only to reduce peak pricing but as an insurance policy for reliability.
  4. Back-Up Power. When extreme weather hits, who has dibs on available natural gas resources? It’s not businesses, it’s residential customers. Individual homes have priority in an emergency, meaning that if being at the back of the line isn’t a good option for your company, perhaps a battery storage system is.

As we head into 2022, and utilities and businesses step up to lead the sustainability charge, backing up carbon-neutral pledges and ESG or CSR plans with measurable actions to reduce greenhouse gas emissions is a priority to diverse stakeholders. A more modern, digital, and distributed grid is emerging to meet the moment, one that allows for more self-reliance and dexterity among power producers and large users of electricity.

Batteries are the catalyst for this smarter, cleaner new world.

Coupled with advanced software, energy storage solutions make utilities and businesses more strategic about how, when and where they use energy, so that it serves the right purpose at the right time. This gives all players the opportunity to be their greenest and most cost-effective, while banking on a dependable energy resource fully under their control.
