I agree with the recommendation of Andrew Morton, however, I would like to clarify some details. To identify kilowatt-hours, I recommend that you use an international identifier from UNECE. E.g.:
"priceSpecification":{
"#type":"UnitPriceSpecification",
"price":"0.27",
"priceCurrency":"EUR",
"referenceQuantity": {
"#type":"QuantitativeValue",
"value":"1",
"unitCode":"KWH",
"sameAs":"http://www.unece.org/fileadmin/DAM/cefact/recommendations/bkup_htm/add3hk.htm"
}
}
In the content of a web page, it may be useful to use the HTML element abbr for an abbreviation of kilowatt-hours
Use the following recommendation for the price property:
Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a
decimal point. Avoid using these symbols as a readability separator.
Update 2019-09-30 related to the following question of JKB:
... But how to extend this example to also declare „base fee“? And, in
addition, set the name of the supplier?
The following markup may probably help you:
{"#context": "http://schema.org/",
"#type":"Service",
"serviceType":"Supply of electricity",
"provider":{
"#type":"LocalBusiness",
"name":"John Doe Provider"
},
"offers":{
"#type":"Offer",
"name":"Base fee",
"price": "9.90",
"priceCurrency": "EUR",
"priceSpecification":{
"#type":"UnitPriceSpecification",
"name":"Working Price",
"price":"0.27",
"priceCurrency":"EUR",
"referenceQuantity": {
"#type":"QuantitativeValue",
"value":"1",
"unitCode":"KWH",
"sameAs":"http://www.unece.org/fileadmin/DAM/cefact/recommendations/bkup_htm/add3hk.htm"
}
}
}
}
I set here the top-level type such as Service however, I do not have a clear understanding of whether this is a service or a product. Therefore you need to clearly determine whether the supply of electricity is a service or is it an intangible product. If this is a product, then adjust this markup for the type Product.
