DTE is committed to delivering safe, reliable and affordable energy. One way we work to keep prices as low as possible is by buying natural gas supplies year-round, often when costs are lower.
We lock in natural gas prices up to three years in advance and buy throughout the year well before you need it. We then safely store the gas underground in naturally-occurring rock formations. These reservoirs, located deep underground, hold the gas until demand increases. Michigan’s geology makes it ideal for storing gas thanks to rock formations that previously held oil and gas, which has since been extracted.
Buying natural gas in advance helps protect you from unexpected price spikes. The majority of our supply is sourced from within the U.S., and we don’t mark up the cost of natural gas – so you pay what we pay.
While the cost of natural gas is constantly changing, our buying and storage strategy is keeping DTE’s costs among the lowest in Michigan and the entire nation.
