The resPolicy.xml
file defines a renewable energy standard policy for
the electricity sector. (Support for other sectors is coming.)
The elements that comprise the resPolicy.xml
file are described below.
This is the outermost element, which takes no attributes and contains one
or more <portfolio-standard>
elements. It may also contain <comment>
elements.
Defines a single portfolio standard, for a given set of regions.
This element takes no attributes and contains one or more
<certificate>
elements, and zero or more <comment>
elements.
The <certificate>
element defines a single renewable energy certificate,
or REC, that is generated by electricity producers that are incentivized by
the policy, and consumed by technologies deemed regulated by the policy.
The <certificate>
element takes a single required attribute, name
,
which is the name of the traded REC.
Attribute | Required | Default | Values |
---|---|---|---|
name | yes | (none) | text |
A <certificate>
element must include exactly one of each of the following
sub-elements: <targets>
, <producers>
, and <consumers>
, and may
contain any number of <comment>
elements.
The <targets>
element takes no attributes and must contain one or more
<target>
elements, and any number of <comment>
elements.
The <target>
element defines the required fraction of total output that
must be covered by RECs, by year. That is, for a 20% RPS in 2020, each regulated
electricity provider would have a target of <target year="2020" fraction="0.2"/>
.
Attribute | Required | Default | Values |
---|---|---|---|
year | yes | (none) | text |
fraction | yes | (none) | float |
The <producers>
defines technologies deemed to produce RECs, i.e., the
renewable technologies incentivized by the policy. The <consumers>
element
defines those technologies which must acquire credits at the level described
in the <targets>
.
The <producers>
and <consumers>
take no attributes, and must each
contain one or more <tech>
elements, can have and any number of <comment>
elements.
The <tech>
element identifies a single technology or set of technologies.
It takes 3 attributes: The (required) sector
attribute identifies a
sector containing some number of technologies. This can be an exact match
for a technology (in the global-technology-database) or a regular expression
matching multiple sectors. The other two attributes, subsector
and
technology
are optional; if not specified all technologies matching the
sector and subsector (if subsector
is provided) or sector (if subsector
is absent) are matched. As with sector
, subsector
and technology
can be exact matches or regular expressions.
Attribute | Required | Default | Values |
---|---|---|---|
sector | yes | (none) | text |
subsector | no | (none) | text |
technology | no | (none) | text |
