Arcadia vs UtilityAPI vs Urjanet
The three names every utility-data build-versus-buy evaluation starts with. Urjanet is now inside Arcadia, which buyers constantly conflate: here is what actually differs.
A product or engineering lead at a broker or climate-software company sourcing a utility data feed will start here, and the first thing worth clearing up is that two of these three are now the same company. Arcadia acquired Urjanet in 2022, and Urjanet’s platform has been consolidating into Arcadia since.
That leaves a genuine two-way comparison, Arcadia and UtilityAPI, plus a migration question for anyone still on Urjanet contracts. Arcadia offers the broadest US ecosystem; UtilityAPI offers stronger customer authorization tooling and deep roots in distributed energy.
Underneath that is the build-versus-buy question these evaluations are really about. Buying a feed is not the same as buying a data layer, and the difference is all the work that turns records into something you can put in front of a customer.

Rows marked “via partner network” are delivered by Nectar partners (energy brokers, procurement consultants, and trading desks in the Nectar Marketplace of Solutions), rather than by Nectar directly. Bill pay is executed by Nectar or through an integrated payment provider depending on the customer.
Competitor details are taken from each vendor’s own published material and were accurate at the time of writing: Arcadia, UtilityAPI, Urjanet.
What each vendor is actually good at
Arcadia
A utility data platform sold primarily as a developer API. Arcadia acquired Urjanet in 2022 and ENGIE Impact in 2026, consolidating utility data feeds and a managed service under one owner.
Best fit for
Product and engineering teams building an energy application who want the raw data feed and will build the workflow themselves.
Where Arcadia wins
- A mature, well-documented API with strong developer adoption
- Broad US coverage, expanded by absorbing the Urjanet base
- Interval data alongside billing data
- A large ecosystem of existing integrations
Where Nectar wins
- Nectar publishes a parsing accuracy figure and backs flagged bills with human QA
- Completeness is a product surface rather than something you build on top of an API
- Line-item parsing across demand, supply, delivery, taxes, and fees out of the box
- A usable application for energy and sustainability teams, not only an API
UtilityAPI
A utility data API focused on authorized access to US utility accounts and interval data, widely used in solar, storage, and demand-side energy applications.
Best fit for
Developers in US clean energy who need customer-authorized interval and billing data with a clear consent flow.
Where UtilityAPI wins
- Strong customer authorization and consent tooling for US utilities
- Well established in solar and distributed energy workflows
- Interval data depth for load analysis
Where Nectar wins
- Nectar covers 7,000+ providers globally rather than a US focus
- Line-item bill parsing across demand, supply, delivery, taxes, and fees
- A completeness view and audit trail rather than raw endpoints alone
- Multi-commodity coverage beyond electricity
Urjanet
A pioneering utility data aggregator acquired by Arcadia in 2022. Its legacy contracts and endpoints are progressively consolidating into the Arcadia platform.
Best fit for
Existing customers running on legacy Urjanet contracts who have not yet re-evaluated their utility data source.
Where Urjanet wins
- A long operating history and established enterprise integrations
- Recognized brand among earlier utility data buyers
- Continuity for teams already built against its endpoints
Where Nectar wins
- Nectar is an independent platform with a roadmap of its own rather than a consolidating legacy product
- Published coverage of 7,000+ providers and 99.2% parsing accuracy
- Completeness tracking and an audit trail to every source bill
- Line-item parsing rather than summary billing fields
Build versus buy is really buy-how-much
Almost nobody builds utility data collection from scratch anymore: maintaining connections to thousands of provider portals that change without notice is a permanent engineering cost with no product differentiation at the end of it. So the real question is how much of the stack you buy.
Buy only the feed and you own parsing depth, completeness detection, provenance retention, and the operational response when a provider changes format. Buy the layer and those arrive with it, at the cost of less control over the shape of the data.
For a company whose product is energy software, the feed-only option looks cheaper and frequently is not, because the maintenance lands on the same engineers building your actual product. Nectar sells the layer through an API precisely for that buyer.
Where Nectar fits
Treat this as Arcadia versus UtilityAPI, with Urjanet as a migration question. Arcadia for ecosystem breadth, UtilityAPI for consent tooling and DER workflows. Choose Nectar when you want the layer rather than the feed: global coverage, line-item parsing, completeness, and provenance, delivered through the same API.
Frequently asked questions
Is Urjanet still a separate product?
Functionally it is consolidating into Arcadia following the 2022 acquisition. If you are evaluating it as an independent option, you are effectively evaluating Arcadia with legacy endpoints, and it is worth asking directly what the support timeline for those endpoints is.
What should a build-versus-buy analysis actually price?
Not just the API contract. Include parsing maintenance, completeness monitoring, provenance storage, and the on-call cost when a provider breaks a format at quarter end. Those are the line items that make feed-only look cheap in a spreadsheet and expensive in practice.
How does Nectar price against a raw feed?
Higher per record than a feed-only vendor and lower than a feed plus the engineering to make it trustworthy. The comparison only makes sense if you cost both sides fully.
Can we start with a feed and add a layer later?
You can, though migrating means re-establishing historical continuity. If you already know your product needs completeness and provenance in front of customers, building it twice is the expensive path.
