Delta-Montrose Electric Association (DMEA) Solar Guide: Net Metering and Banking

If you are a Delta-Montrose Electric Association member thinking about solar, here is the short version: DMEA uses a kilowatt hour banking model, so the surplus your panels send to the grid is stored as a credit you draw down later rather than cashed out at full retail every month. The piece that matters most for your numbers is how those banked credits are eventually trued up, which DMEA settles at an avoided-cost rate. That rate is lower than retail and changes over time, so the smart play with DMEA solar net metering is to size your system to your own usage and lean on the bank, not to oversize and hope the leftover is paid out at a high price.

DMEA is a member owned cooperative serving Delta, Montrose and much of the surrounding Western Slope, including the North Fork Valley and the communities along the Uncompahgre and Gunnison rivers. Because it is a co-op rather than an investor owned utility, its board sets the local solar rules, fees and crediting structure. That is why DMEA solar follows its own playbook, and the details differ from what a friend on a different utility may have told you.

How DMEA solar net metering and kWh banking work

Net metering is the billing arrangement that credits you for the solar energy your system exports to the grid. When your panels produce more than your home is using, the surplus flows out onto DMEA's lines and your meter records that export. At night or on cloudy days, you pull power back from the grid as usual. If you are new to the concept, our overview of how net metering works walks through the mechanics step by step.

What makes DMEA distinct is the banking layer. Rather than zeroing out your account every single month, DMEA carries your net excess generation forward as a credit in kilowatt hours. Think of it as a savings account measured in energy. In the long, sunny days of late spring and summer, your system likely produces more than you use, and those surplus kilowatt hours go into the bank. In the short days of winter, when production drops and heating loads climb, you draw that banked energy back down. Over a full year the goal is for the bank to smooth out the seasonal swings.

What banking means for your bill

• Month to month, surplus does not disappear. A high production month builds a credit you can use in a low production month, so a strong summer helps cover a lean December.
• The bank is denominated in energy, not dollars. Because credits are tracked as kilowatt hours, a banked kilowatt hour offsets a kilowatt hour you would otherwise buy, which protects its value as long as you are using it against your own consumption.
• The settlement is where the rate matters. Banking is generous while you are drawing credits down against your own usage. The question is what happens to any net surplus that remains at the true-up, which we cover next.

True-up and the avoided-cost rate

At a defined point in the cycle, DMEA settles, or trues up, any accumulated net generation that you did not use yourself. That leftover surplus is credited at an avoided-cost rate rather than the full retail rate. Avoided cost is roughly what it would have cost the co-op to generate or buy that power elsewhere, and it is meaningfully lower than the retail rate you pay to consume electricity.

Important caveat on the exact figure: the specific DMEA avoided-cost true-up rate should be treated as approximate and confirmed before you rely on it. Co-op rates are set by the board and updated periodically through the tariff, so the number that applies to your project may differ from any figure quoted online or by a salesperson. Please confirm the current avoided-cost true-up rate, and the exact settlement timing, directly with DMEA before you finalize a system design. We will pull the live tariff with you as part of your proposal so the math reflects what you will actually receive.

The practical takeaway is the same one that applies across most Colorado co-ops: a banking-plus-avoided-cost model rewards self consumption and penalizes oversizing. Every kilowatt hour you use on site, or bank and later use yourself, holds full value. Every kilowatt hour that spills over at the annual true-up is paid at the lower avoided-cost rate. So the design target is a system that closely matches your annual usage rather than one that produces a large permanent surplus.

Sizing your DMEA solar system the right way

Because DMEA credits banked energy that you use yourself at full value and trues up leftover surplus at avoided cost, sizing is the single most important design decision. A system sized to roughly cover your annual consumption lets you use almost everything you generate, either in real time or out of the bank, and leaves little to settle at the low rate.

A few things shape the right size on the Western Slope:

• Your real usage history. We start from twelve months of your actual kilowatt hours, not a rule of thumb, so the array is matched to your home.
• Seasonal load shape. Electric heat, a heat pump, a well pump or an EV all change the winter draw, which is exactly when the bank gets spent down. The banking model is most valuable when summer surplus is sized to carry those winter months.
• Future electrification. If a heat pump or EV is on your horizon, we can plan for that load now so you are not undersized in a year.

This avoided-cost banking structure is common across Western Slope co-ops. Members just up the valley around Grand Junction run into a comparable buyback approach with Grand Valley Power, which also settles excess at avoided cost. The lesson is consistent: match production to usage and keep the value on your side of the meter.

Does a battery make sense with DMEA?

A battery is not required to benefit from DMEA net metering, since the kilowatt hour bank already shifts energy across seasons. But storage can still earn its keep, especially for homes that want backup during Western Slope outages or that have a load shape where production and usage do not line up well. A battery stores midday solar for evening use, which keeps more energy on site at full value instead of leaning on the grid. Some neighboring co-ops actively reward storage with rebates, such as the program in nearby Gunnison County Electric territory, so it is always worth checking whether DMEA has any current storage incentive when you plan your project.

Why work with ProGreen Solar in DMEA territory

ProGreen Solar is a Colorado company serving both the Front Range and the Western Slope. We are NABCEP certified, hold an A plus rating from the BBB, and are a licensed electrical contractor under EC.0101788. With a co-op like DMEA, the difference between a system that pencils out and one that disappoints usually comes down to the local details: how the kilowatt hour bank works, when the true-up lands, and what the current avoided-cost rate actually is. We design to those specifics, confirm the live DMEA tariff with you rather than guessing, and size your array to your own usage so your banked energy stays valuable.

Getting started

Solar with Delta-Montrose Electric Association is a strong fit once you understand the kilowatt hour banking model and plan around the avoided-cost true-up. The smartest first step is a usage review so we can size your system to your home, confirm the current DMEA banking and true-up terms together, and show you whether storage adds value for your situation.
