Tech and industry (Energy and utilities), Renewable share

Today's generation mix as a departures board: the share from renewables large on flaps as the headline, the mix by source (up to eight) as one bar and a board of rows with their shares, the date and the source, the supplier's notice at the foot throughout. The board ripples, each source is told in turn, before a tip, the button and the presenter. About eight to twelve seconds: it grows with the number of sources.

What it accepts

Today's generation mix as a departures board: the share from renewables large on flaps as the headline, the mix by source (up to eight) as one bar and a board of rows with their shares, the date and the source, your notice throughout. Each source told in turn, then a tip, the button and your presenter. Eight to twelve seconds, by the number of sources. metaData is never drawn.

Field	Type	Required	Limit	What it is
`clipData`	group	yes		Clip data: Everything drawn in the clip: the share from renewables, the sources and their shares, the day and area, the source of the figures, the words on the board, the tip, the call to action and your notice.
`clipData.section`	text		up to 32 characters	Section: The section in the header, painted as a sign beside your title line, such as Generation mix.
`clipData.kicker`	text		up to 40 characters	Kicker: A short line above the headline, such as Electricity generation today.
`clipData.headline`	text		up to 64 characters	Headline: The headline, set large. Say what the mix shows; it must agree with the share below.
`clipData.day`	datetime	yes		Day: The day the mix is for, such as 2026-10-18T00:00:00+02:00. Only the date is read, as it is written here, and it is spelled out in the channel's language under the headline.
`clipData.area`	text		up to 40 characters	Area: The grid or country the mix is for, shown after the date, such as Germany or Great Britain.
`clipData.renewableShare`	number	yes	from 0, to 100, 1 decimals	Share from renewables: The share of today's generation that comes from renewable sources, in percent, as you state it, such as 62.4. It is the headline figure and is drawn exactly as sent: the template adds nothing up.
`clipData.sources`	list	yes	at least 2, up to 8	Sources of power: Two to eight sources in the order they should be shown, each with its share of generation in percent as sent (they should add up to 100). Each is a segment of the bar and a row of the board.
`clipData.sources[]`	group			Source of power
`clipData.sources[].name`	text	yes	up to 24 characters	Name: The source, such as Wind, Solar, Hydropower or Natural gas.
`clipData.sources[].share`	number	yes	from 0, to 100, 1 decimals	Share: Its share of generation in percent, drawn exactly as sent.
`clipData.sources[].renewable`	boolean			Renewable: Marks the source as renewable: its row carries the renewable tag from your words below.
`clipData.source`	text	yes	up to 80 characters	Source: Where the figures come from, shown under the board, such as Source: ENTSO-E Transparency Platform, net public generation.
`clipData.labels`	group			Words on the board: The words the board shows beside the figures, in your language.
`clipData.labels.renewables`	text		up to 24 characters	Renewables: The caption over the headline share, such as Renewables.
`clipData.labels.tag`	text		up to 16 characters	Renewable tag: Shown on the row of every source marked renewable, such as Renewable.
`clipData.labels.name`	text		up to 24 characters	Source heading: The heading over the names, such as Source of power.
`clipData.labels.share`	text		up to 16 characters	Share heading: The heading over the shares, such as Share.
`clipData.tip`	text		up to 120 characters	Tip: One sentence shown at the end above the button, such as when power is greenest. Name nothing the mix does not show; never promise a saving.
`clipData.cta`	group			Call to action: The button at the end and the line under it, such as a web address, a handle or a phone number.
`clipData.cta.label`	text	yes	up to 28 characters	Button: What the button says.
`clipData.cta.detail`	text		up to 48 characters	Line under it: An address, a handle, an app, a phone number.
`clipData.notice`	text	yes	up to 300 characters	Notice: Who supplies, your licence or registration, and whether the mix is the grid's or your own supply's, as your regulator asks. Shown at the foot from the first frame to the last; a long notice is set smaller, never cut.
`clipData.footnote`	text		up to 200 characters	Small print: Any other line that must be shown, such as how the shares were measured or that they may be revised.
`clipData.look`	group			Look: How the clip looks and moves. The same six switches in every format (theme, pace, corners, alignment, logo, logo size). Leave any out for the package's default: dark, standard pace, softly rounded, text at the start.
`clipData.look.theme`	enum		`brand`, `light`, `dark`, `bold`	Theme: Brand: your brand's own colours and background. Light or dark: a page tinted with your brand colour. Bold: your brand colour as the page.
`clipData.look.pace`	enum		`calm`, `standard`, `punchy`	Pace: How things arrive: calm fades, a standard rhythm, or punchy slams and hard cuts.
`clipData.look.corners`	enum		`square`, `soft`, `round`	Corners: The shape of cards, pictures and buttons.
`clipData.look.align`	enum		`start`, `centre`	Text alignment: Where the text lines up.
`clipData.look.logo`	enum		`auto`, `free`	Logo: The style's own: the logo on a small plate so it reads on any page. As it is: the logo whole, with no plate, frame or crop, for a logo made to stand on the page, such as one with a transparent background. As it is, make sure your logo reads on the page of the theme you choose.
`clipData.look.logoSize`	enum		`auto`, `small`, `large`	Logo size: Standard is the style's own size. Small draws the logo a fifth smaller, with its plate. Large draws it a quarter larger wherever the style has room for it, and at the standard size where it has none.
`metaData`	group			Meta data: Everything about the post that is never drawn in the clip: its title, its description in four lengths, one per kind of platform, and its hashtags. Reelwire adds the brand's description, link and hashtags after it. Left out, the post text is generated from the clip data.
`metaData.title`	text		up to 100 characters	Title: Used where the platform has a title of its own: Facebook Feed, LinkedIn, Pinterest and YouTube. Up to 100 characters, which every one of them takes.
`metaData.captionTiny`	text		up to 200 characters	Tiny description (Pinterest, Threads, X): Up to 200 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionShort`	text		up to 500 characters	Short description (Telegram, Threema, WeChat, WhatsApp): Up to 500 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionMedium`	text		up to 1500 characters	Medium description (Discord, Facebook Reels, Instagram, LinkedIn, Signal, Slack, TikTok): Up to 1500 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.captionLong`	text		up to 4000 characters	Long description (Facebook Feed, YouTube): Up to 4000 characters. The brand's description, link and hashtags follow it within the platform's limit.
`metaData.hashtags`	list		up to 15	Hashtags: Written without the #. Up to 15, which every platform takes.
`metaData.hashtags[]`	text		up to 60 characters	Hashtag

locales carries other languages: under each language code, the parts of clipData and metaData that differ, laid over the default, so a language with no copy still renders.

A picture is always a file from your media library: media:// followed by its id or its name. Anything the table does not list is refused, and so is anything over its limit, with a 400 schema_validation error that names the field.

Your own system sends this to one of your streams, POST /v1/stream, and every channel listening to that stream draws it with its template. data is the document described above; a stream with an empty field map passes it to the template unchanged. Try it first on POST /v1/stream/validate, which answers the same without publishing anything. Streams and feeds explains the rest, including how to map a document of your own shape instead.

The delivery names no version: which build draws it is the channel's choice, the newest of its variant or the one it is pinned to. eventId is a ULID you make once per event: sending the same one again changes nothing. occurredAt is when the thing happened, not when you sent it. locale is the language of the text in data, and data.locales carries other languages beside it.
