Smart-meter readings and travel-card data can show how people live and move. Supply, billing and planning fit the purpose consumers gave data for; offers from partners do not. Aggregate wherever the question allows.
The first four things to sort out
Check the purpose before each analysis.
Aggregate meter and travel data for planning.
Never share consumer lists for partners' own offers.
Give analysis copies their own deletion date.
A worked example
Data and analytics head
A discom plans load forecasting with smart-meter data
Day 1Planning asks for household-level readings for a year.
Day 3The team checks the purpose: billing and supply planning are covered.
Week 1The model uses readings totalled by feeder and area, with no consumer names.
AfterThe household-level copy is deleted and the aggregate is kept.

Planning needs totals, not households.

9 questions the Data and analytics head asks, answered in full
Short answer: Yes, you are responsible for what they do with your consumers' data
When distributors, dealers or franchisees handle consumer data for your service, they act for you, and you are responsible. Give them only what they need, add a data clause to agreements, train them, and check a sample every year. If a partner uses data for its own business, such as selling insurance, that is outside your purpose and must stop.
Short answer: Yes, within the purpose or with consent
Yes, where the use fits the purpose people were told, or you have consent for it. Improving the service people signed up for usually fits. Selling insights, profiling for third parties or targeting children does not. Mask or aggregate wherever the question allows, and give analysis copies their own deletion date.
From your seat: Data and analytics head. Check the purpose before each new analysis. Purpose decides whether you need consent.
What the law says
Section 4 needs a lawful basis for each purpose. Section 6 needs specific consent. Section 9 bars behavioural monitoring of children. Section 8(3) asks for accuracy when data drives decisions. Section 4 · Section 6 · Section 9 · Rules 10, 12 · Section 8(3)
Short answer: It depends on the use; most organisations need both
For every use of personal data you need one basis: consent, or one of the legitimate uses in Section 7, such as a legal duty, employment, a medical emergency, or data a person gave voluntarily for a specific purpose. Anything beyond what the person expects, such as marketing, profiling or sharing with partners, usually needs consent.
From your seat: Data and analytics head. Your models can only use data whose basis covers that use.
Example in PSUs and utilities
Supplying the service rests on the purpose consumers gave data for; marketing and partner offers need consent.
What the law says
Section 4 allows processing only with consent or for a legitimate use. Section 6 sets what valid consent looks like. Section 7 lists the uses that need no consent. Section 4 · Section 6 · Section 7
Steps
List each purpose for which you use personal data.
Against each purpose, write the basis: consent or the exact clause of Section 7.
Where the basis is consent, check that it was asked separately, with a clear action and no pre-ticked box.
Stop or re-paper any purpose with no basis.
Review the list whenever a new product, campaign or system starts.
Evidence to keep
Purpose and basis register
Consent records with date, version and channel
Legal sign-off on each legitimate use relied on
Common mistakes
Treating account terms as consent for marketing
Bundling several purposes in one tick-box
Relying on 'legitimate interest', which the Indian Act does not have
Short answer: Four questions at design, then build the basics in
Ask four questions at the design stage: what personal data, why, for how long, and who sees it. Then build in what the Act assumes: a notice, consent where needed, role-based access, logs of record views, a way to delete, and a way to answer requests. Adding these after launch costs far more.
From your seat: Data and analytics head. Work with masked or aggregated data wherever the question allows.
Short answer: Required only for SDFs; good practice for high-risk changes
By law, only Significant Data Fiduciaries must do a yearly impact assessment. For everyone else it is good practice for high-risk changes: new tracking, profiling, large data sharing, children's data or moving data abroad. A short assessment before the change is cheaper than fixing it later.
From your seat: Data and analytics head. Profiling and automated decisions deserve an assessment.
Short answer: Check every channel; children often appear where you least expect
Anyone under 18 is a child under the Act. For a child's data you need verifiable consent from a parent or lawful guardian, and you must not track, behaviourally monitor or show targeted ads to children. Some classes and purposes are exempt under Rule 12 and the Fourth Schedule, for example healthcare to the extent needed to protect the child's health, and educational institutions for their educational work.
From your seat: Data and analytics head. No behavioural monitoring of under-18s.
Example in PSUs and utilities
PSU schools and hospitals handle children's data.
What the law says
Section 9 sets the duties. Rule 10 explains how to verify the parent. Rule 12 and the Fourth Schedule list the exemptions. Section 9 · Rules 10, 12 · Section 6
Steps
Find where children's data enters: customers, dependants, interns, visitors, scholarships, app sign-ups.
Decide whether an exemption in the Fourth Schedule applies to that purpose.
Where none applies, add an age question and a parent-consent step.
Switch off tracking and targeted ads for under-18 users.
Record the decision for each channel.
Evidence to keep
Channel-by-channel note on children's data
Parent-consent records
Ad and tracking settings
Common mistakes
Assuming 'we are B2B, so no children'
Using the age 13 or 16 from foreign laws
Treating a tick-box from the child as parental consent
Short answer: For the legal or business period, then erase
Keep data for as long as its purpose needs, or as long as a law requires, and then erase it. Every organisation must keep personal data and logs for at least one year under Rule 8(3). Write a retention schedule by record type, with the law or reason against each period.
From your seat: Data and analytics head. Analytics copies often outlive the source. Give them their own period.
Example in PSUs and utilities
Pension and service records are kept long; consumer records follow legal and business needs.
What the law says
Section 8(7) asks for erasure when the purpose is over, unless a law requires retention. Rule 8(3) sets a one-year minimum for personal data, traffic data and logs. Section 8(7) · Rule 8 · Section 8(5) · Rule 6
Steps
List the record types you hold.
Write the period for each, with the law, regulator rule or business reason.
Set a trigger for the period to start: end of relationship, date of transaction, exit date.
Automate deletion where you can; for paper, schedule shredding.
Keep a deletion log.
Evidence to keep
Retention schedule approved by Legal
Deletion log
Shredding or disposal certificates
Common mistakes
'Keep everything forever' because storage is cheap
Usually in more places than anyone expects: core systems, email, shared drives, laptops, vendor systems, backups, test copies, spreadsheets and paper. A simple inventory, one row per system, is the base for every other duty.
From your seat: Data and analytics head. Register every data set and its source.
Example in PSUs and utilities
Include distributor software and township systems.
Short answer: Yes, every vendor that touches personal data
You stay responsible for what your vendors do with personal data. The contract should say what data they get, for what purpose, the security they must keep, how fast they must tell you about an incident, that sub-contractors need your approval, and how data is returned or deleted at the end.
From your seat: Data and analytics head. Analytics and cloud vendors receive large copies. Check their terms.
Example in PSUs and utilities
Distributors, franchisees, meter vendors, ticketing vendors and labour contractors.
DPDP Act, Section 2(x) and Article 12 of the Constitution
The Act defines 'State' with the meaning in Article 12. Many PSUs have been treated as 'the State' by courts, depending on government control.
Get a legal view on which activities can rely on Section 7(b), 7(c) and 17(4). Customer-facing commercial work usually follows full duties.
